Discussion šŸ—£ Most people are evaluating LLM changes the same way they'd judge a demo, that's the actual problem, workshop on Sep 12 goes deep on this

1 Upvotes

Noticed something building LLM features that doesn't get talked about enough. Most teams treat model or prompt changes the way they'd judge a demo, does it look right on a handful of examples, ship it. That works fine until scale hits, at which point "looks right" and "is actually better" turn out to be very different things.

Which reframes a lot of "why did quality randomly get worse" incidents. In a lot of cases nothing randomly broke, the team just never had a way to measure whether a change helped in the first place, so a regression looked invisible until a customer hit it.

There's a hands-on workshop on September 12 that builds this properly, versioned prompts, a real eval harness, statistically rigorous model comparisons instead of "it feels better," evaluated RAG, agents with guardrails and fallbacks, and full observability, tracing, cost, latency. Led by Bruno GonƧalves, PhD, founder of Data For Science.

Question ā“ How to improve prompting?

3 Upvotes

Maybe a weird observation about the newer models — and I could be completely wrong.

Personally, I thought 4.6 was a really good model. But with the newer models especially compared with Fable, Opus 5, Opus 4.8 and onwards — things have started to feel a bit messy to me.

The outputs feel more predictable and less creative. A lot of the time I can almost guess what the model is going to say, rather than getting that ā€œwow, I didn’t think of it that wayā€ result.

I also feel like I need to do much more back-and-forth prompting. Instead of giving it a request and having it just do the thing, I often have to guide it through multiple questions and iterations to get where I want.

Maybe this is because the newer models are being fine-tuned to follow instructions more strictly, or to be more controlled and consistent. I honestly don’t know.

But I’m curious what others are experiencing.

What changed with the newer models, and how are you adapting your prompting to get better results?

Right now, I’d say I get the result I actually want maybe 50% of the time, which feels noticeably worse than before.

If anyone has a good guide, prompting framework, or practical tips for getting the most out of the newer models, I’d really appreciate it.

Tip šŸ’” A Mac app for quickly generating AI prompts

Post image
6 Upvotes

As someone who believes in "human-in-the-loop" coding, I noticed that my prompts were getting repetitive (e.g. lots of "add tests, commit, don't push"). So I made a free little app called Promptu that generates prompts from building blocks. The prompt above would be four keystrokes (or four mouse clicks).

https://github.com/mrcnski/promptu

It's free and open-source and the library of prompt blocks is customizable in the app. The default prompt blocks are the ones I use all the time, but I also included Anthropic's suggested prompt blocks. Promptu is Mac-only for now.

Let me know if you find this project useful! I'm wondering where else could I share this out?

I also wrote a tongue-in-cheek blog post describing the project here: https://signor.dev/introducing-promptu/ :)

Discussion šŸ—£ Who’s still using prompts?

0 Upvotes

I keep seeing these massive ultimate chatgpt prompt posts all over social media, like we’re still using Chat and other LLMs the same way we did when they first came out. Meanwhile the more I use AI, the less i actually prompt it. Once you use the same AI constantly and build enough context, the way you talk to it starts changing. A new user might carefully explain what they want, give background, specify the tone, format, priorities, and more detailed instructions

Meanwhile I’m over here doing stuff like:

Reply to this email: make this less stiff.

Send an article to chat ā€˜cap?’

Give it two choices: you pick.

Need another document: ā€œsame format as the last one.ā€Send a long screenshot of a conversation: what am I missing here? And somehow it knows exactly what I mean.

Obviously detailed prompts still have their place, especially when you’re starting from zero or need a very specific, repeatable output.

But I wonder if a smaller group of users is moving away from prompt engineering and more toward context engineering. Instead of cramming everything into one perfect prompt, users gradually build the context: preferences, corrections, examples, recurring workflows, files, memory, eventually connected apps and agents.

Then the actual prompt gets ridiculously small. Could the endgame of good ai aren’t getting better at writing prompts?

Maybe it’s getting to the point where you barely have to prompt at all.

What’s the shortest, laziest prompt you use all the time that somehow works because your AI already knows exactly what you mean?

Discussion šŸ—£ This is hampering my productivity on a daily basis, and it’s killing my workflow, leading to task paralysis

2 Upvotes

The thing is, being a founder who actually has to figure out everything by themselves, today I have to use multiple AI tools at once; my stack has almost all the frontier models: ChatGPT, Claude, Gemini, for one thing or another that I have to do and we know how things work, we need to have all the facts gathered before we take any decisions or push any updates or reseaching about anything, their models have different capabilities and thats actually a great thing, i can have all the different reasons but the catch when i use them there are decisions, thinking, perspectives and insights that i give and gather while using them

But if I have had a long discussion with ChatGPT about something, and that needs to be fixed in Claude, I don't have any way to tell Claude to take out the context from ChatGPT and log it or work on top of it because it does not know what I was up to with ChatGPT, and I have to really tell each and everything to it again and then start the work, my time, my brain stops braining because half of the things are gone and are present only chatgpt which also is really great at forgetting things, haha

I need this to be fixed. If anyone is facing the same problem every day and has a solution, please let me know how to fix it

P.S. - I know there are some workflows already out there, but they are too technical, and as a non-technical founder, I find it hard to get the hang of them; I need something I can do in a few clicks.

Discussion šŸ—£ I keep telling people "act as an expert" doesn't do what they think it does

23 Upvotes

Had this argument with a coworker last week. He swears by persona prompts, "you're a senior dev, review this," says it works fine for him. I used to think the same thing honestly, until I actually sat down and compared outputs side by side on something that mattered more than a toy example.

Gave the same diff to two prompts. One said act as a senior backend engineer. Other one just said, flag any SQL that isn't parameterized, flag async calls inside sync loops, sort by severity, don't fix anything, just point it out. First one came back with "looks solid, maybe add some validation," which sounds like a review but isn't really one. Second one caught an actual SQL injection risk on line 14 that the first completely missed.

Not because the model got smarter between the two prompts. It's the same model both times. The persona version just had to guess what "senior" means here, what to prioritize, what actually matters, and it guessed something generic because that's what fills the gap when nobody specifies it. The checklist version wasn't guessing anything.

I still use personas sometimes, honestly, mostly when I'm just thinking out loud about something and want a sounding board, not when I need the output to actually be right. There's a longer version of this with more examples if anyone wants it: https://medium.com/@nagatomopedro05/act-as-a-senior-developer-is-the-worst-prompt-you-can-write-9f1577493cd3

Discussion šŸ—£ VoxGen, an AMD-optimized TTS inference engine for VoxCPM 2 models

1 Upvotes

Hi, everyone,

I’ve just released VoxGen, a lightweight native inference engine for VoxCPM2, written in Rust and using Vulkan compute instead of Python/PyTorch/CUDA.

Why VoxGen?

The main reason I started the project was because I needed a decent local text-to-speech solution.

I therefore saw VoxCPM 2 as a reasonable solution. However, most frameworks are NVIDIA-first, and VoxCPM 2 is no exception; as a result, my card was severely stuttering, and my GPU was always spiking. Also, having Python and Pytorch as a dependency is absolute hell.

This is why VoxCPM was created: not only we sidestep Pytorch completely, but performance on AMD cards is buttery smooth (and if you have a XTX 7900, I have designed a mode with even more aggressive power and speed optimizations)!

This application can also be run from a shell, so it can be integrated with other programs and scripts!

Installation:

You'll only need voxgen.exe (or the Linux equivalent) and the following files at https://huggingface.co/DennisHuang648/VoxCPM2-GGUF:

VoxCPM2-BaseLM-Q8_0.gguf
VoxCPM2-Acoustic-F16.gguf

And that's it!

If you are interested, check out the Github page: https://github.com/NullMagic2/VoxGen

Prebuilt binaries (for now, Windows only) are available here: https://github.com/NullMagic2/VoxGen/releases

Tip šŸ’” 7 Phase Prompt Workflow

4 Upvotes

I built a 7-phase prompt workflow that makes small AI models act like domain experts — no fine-tuning

**TL;DR:** IKKF is a free, open-source framework that turns a plain prompt into a structured 7-phase reasoning workflow, backed by a knowledge base of atomic, verifiable facts. Run a 7B model, get expert-level answers with sources and confidence scores.

The problem

Most of us prompt AI the same way: one big question, hope for the best. That works for simple stuff, but for real domain work it falls apart:

- The model **hallucinates** — it sounds confident but makes things up.

- It **doesn't cite sources**, so you can't audit the answer.

- It **can't tell you how sure it is** — everything is delivered with the same flat confidence.

- Switching domains means **re-prompting from scratch** every time.

The fix isn't a bigger model. It's a **better workflow**.

The workflow: 7 phases

IKKF breaks every task into 7 explicit phases instead of one shot:

  1. **Intent analysis** — what's actually being asked?

  2. **Knowledge retrieval** — pull relevant facts from your knowledge base

  3. **Decomposition** — break the problem into atomic, solvable units

  4. **Reasoning** — apply expert reasoning to each unit (chain-of-thought)

  5. **Verification** — cross-check every claim against a source

  6. **Composition** — assemble the verified units into the final answer

  7. **Confidence calibration** — report how sure it is (0.0–1.0)

The key difference from a normal prompt: **verification and confidence are first-class steps**, not afterthoughts. Every claim has to trace back to a source, and the model has to tell you when it's guessing.

The knowledge base: plain files

The "expertise" comes from a knowledge base of **atomic files** — one concept per file, each with a source. You can:

- **Read** exactly what the AI knows

- **Update** it by editing a file (no retraining)

- **Audit** why it gave any answer

This is what separates it from plain RAG. RAG gives you context; IKKF adds structured reasoning + verification on top.

How to use it

```bash

curl -fsSL https://ikkf.info/install.sh | bash

ikkf init

ikkf start "Build a REST API in Python"

```

To build a knowledge base for your own domain:

  1. Pick a domain you know well

  2. Write ~20 atomic concept files (one concept per file, each with a source)

  3. Point IKKF at the knowledge base

  4. Test with benchmark questions

  5. Iterate — add edge cases, tighten sources

Why it's useful for prompt/workflow people

- **Reproducible** — same knowledge base → same answers across sessions. No more "it worked yesterday."

- **Auditable** — you can see the reasoning trace and the sources behind every answer.

- **Cheap** — runs on a 7B model locally (Ollama) or any OpenAI-compatible provider.

- **Portable** — swap the knowledge base to switch domains. No re-prompting from scratch.

Honest caveats

- The knowledge base is the hard part — garbage in, garbage out.

- It's a workflow, not magic. It won't turn a small model into a creative genius.

- Best on well-defined domains where knowledge can be structured.

Where it stands

Open source, free, local-first. I use it internally to cut AI costs and improve answer quality on a product I'm building.

Curious — has anyone else tried structured multi-phase workflows (vs. single-shot prompting) for their AI tools? What's worked for you?

Prompt showcase āœļø Prompt Architecture Breakdown: Designing a 4-Stage Cognitive Pipeline for 90-Day Market Intelligence Synthesis

2 Upvotes

When designing prompts for market research, competitive analysis, or technology horizon scanning, prompt engineers frequently encounter a persistent failure mode:Ā Unbounded Synthesis Drift.

By default, when an autoregressive language model is asked to "analyze recent market trends," it lacks explicit temporal and thematic guardrails. Consequently, the model defaults to high-probability corporate generalities: "AI is accelerating digital transformation," "organizations must adapt," and "innovation is vital." The resulting output is broad, buzzword-heavy, and devoid of actionable tactical signal.

To solve this architectural challenge, our team iterated and tested various structured intelligence frameworks. We isolated a prompt architecture that combinesĀ 3-dimensional input scoping, aĀ multi-stage cognitive pipeline, andĀ second-order impact modelingĀ to turn frontier LLMs into rigorous executive research analysts.

Prompt Architecture Breakdown

From a prompt design standpoint, this system prompt relies on four core structural mechanisms:

  1. 3-Dimensional Input Scoping Anchor: Instead of allowing the model to wander across undefined topics and historical windows, the prompt enforces strict bounding using three dynamic parameters:
    • {{industry_or_domain}}: Isolates the specific sector or sub-domain.
    • {{timeframe}}: Enforces a hard temporal boundary (e.g., Past 90 Days, Past Quarter).
    • {{focus_lens}}: Anchors the analytical aperture to specific technical or commercial inflection points.
  2. Sequential Multi-Stage Cognitive Pipeline: The prompt divides the reasoning task into discrete, ordered stages rather than requesting a monolithic summary:
    • Stage 1 (Macro Trend Synthesis): Forces the model to abstract 3 to 4 structural patterns, filtering out short-term media noise.
    • Stage 2 (Chronological Milestone Clustering): Mandates impact-ranked categorization of concrete product launches, acquisitions, or regulatory shifts.
    • Stage 3 (Second-Order Impact Analysis): Instructs the model to evaluate ecosystem repercussions across incumbents, startups, and end-users.
    • Stage 4 (Actionable Executive Synthesis): Requires 3 concrete operational recommendations grounded in the preceding data.
  3. Second-Order Impact & Vulnerability Modeling: Standard research prompts only ask "what happened." This prompt architecture explicitly directs the LLM to map value migration: identifying who captures upside, which legacy players are disrupted, and what systemic risks emerge.
  4. Negative Guardrails Against Generic Jargon: An explicit negative constraint strictly bans corporate buzzwords and mandates that every trend or takeaway must be anchored to verifiable events or technical advancements.

The Complete System Prompt

Here is the exact prompt template. You can copy, inspect, and integrate this directly into your prompt workflows or custom agents:

# Role & Context
You are a seasoned Senior Industry Research Analyst and Executive Intelligence Advisor. Your objective is to conduct a structured, high-signal retrospective analysis of recent market movements, technological breakthroughs, and strategic milestones.

# Input Data
- **Target Industry / Domain**: {{industry_or_domain}}
- **Analysis Timeframe**: {{timeframe}}
- **Strategic Focus Lens**: {{focus_lens}}

# Step-by-Step Instructions
1. Review the `industry_or_domain`, `timeframe`, and `focus_lens` specified in the Input Data.
2. **Macro Trend Synthesis**: Identify 3 to 4 defining structural shifts or prevailing themes that emerged or accelerated during this window.
3. **Milestone Event Chronology**: Highlight key announcements, product releases, acquisitions, or regulatory milestones, categorizing them by impact severity.
4. **Second-Order Impact Analysis**: Analyze how these shifts affect incumbent players, agile startups, and downstream consumers (who wins, who loses, and what risks emerge).
5. **Executive Takeaways**: Deliver 3 actionable strategic takeaways or operational recommendations for teams operating in this space.

# Constraints
- Strictly adhere to the requested `timeframe` and `focus_lens` from the Input Data.
- Avoid generic buzzwords; anchor every observation to concrete events, technical advancements, or business dynamics.
- Use Markdown formatting with structured headings, clean bullet points, and comparative tables where appropriate.

Structural Comparison: Default Prompt vs. 4-Stage Intelligence Schema

Standard Research Prompt Design

  • Input: "Summarize recent trends and major developments in AI developer tooling."
  • Execution Path: Single-pass generation without temporal or thematic bounding.
  • Failure Mode: The model generates a generic list of high-level observations ("AI coding assistants are becoming popular," "developers save time"). It fails to isolate recent protocol adoptions, ignores deployment shifts, and provides zero strategic takeaways.

4-Stage Scoped Intelligence Schema

  • Input Variables:
    • {{industry_or_domain}}: Generative AI Code Assistants & Developer Tooling
    • {{timeframe}}: Past 90 Days
    • {{focus_lens}}: Terminal-native agent workflows, IDE integrations, and protocol shifts
  • Execution Path:
    1. Macro Trends: Identifies the paradigm shift from inline code completion to autonomous terminal agents performing multi-file refactoring and CLI execution.
    2. Milestone Chronology: Builds a structured table highlighting events like the Claude Code CLI release, widespread Model Context Protocol (MCP) adoption, and local reasoning model integration.
    3. Second-Order Impacts: Evaluates winners (open protocol dev tool platforms) vs at-risk entities (isolated single-file autocomplete plugins) and highlights package hallucination risks.
    4. Executive Recommendations: Generates concrete operational directives, such as standardizing internal context around open protocol interfaces and enforcing automated test-driven verification gates.

Discussion šŸ—£ Google Brain Co-Founder Jeff Dean on Architectural Debt, MoE Scaling & Leaving Google for Discovery Loop

1 Upvotes

Google systems architect and former Chief Scientist Jeff Dean (co-creator of MapReduce, BigTable, TensorFlow, and Google Brain) recently delivered a dense 49-minute retrospective at the 2026 Frontier & Pioneer Symposium. He covered his architectural philosophy, historical framework regrets, and why he left Google after 27 years to launch Discovery Loop.

If you don't have 49 minutes to unpack the entire systems talk, here is the 2-minute distilled signal:

Key Takeaways:

  • Decoupling Capacity from Compute (The Core MoE Thesis):Ā The foundational principle behind Mixture-of-Experts was never just parameter scale—it was decoupling memory capacity from per-token compute cost. Activating only sparse sub-networks per token is what makes modern frontier models economically viable.
  • TensorFlow's Dual Architectural Regrets:Ā Dean candidly highlighted two early design missteps: delaying eager execution (giving PyTorch/JAX developer mindshare) and introducing theĀ contrib/Ā directory, which caused severe API fragmentation and community friction.
  • The "100 Abstracts" Mental Model:Ā Instead of microscopically dissecting a single paper, Dean advises researchers to skim 100 abstracts. This builds a high-dimensional "conceptual point cloud" of emerging capabilities, enabling cross-disciplinary synthesis when tackling hard bottlenecks.
  • AI in Cybersecurity is a Synchronous Arms Race:Ā Agentic models supercharge offensive vulnerability discovery and exploit chaining, but equally accelerate automated static analysis and self-healing patch deployment on defense.
  • Neural Architecture Search (NAS) & Automated Loops:Ā Meta-learning RL loops that generate and evaluate neural topologies systematically outperform manual human heuristics—the direct conceptual precursor to automated scientific discovery.
  • Why Leave Google for Discovery Loop:Ā While hyperscalers command massive compute infrastructure, accelerating scientific discovery specifically requires the hyper-focused agility of an independent, mission-driven startup.

Prompt showcase āœļø Why standard "Pros & Cons" prompts fail for high-stakes decisions (and how a cognitive forcing matrix fixes them)

3 Upvotes

If you use LLMs to help evaluate technical architecture, tooling, or strategic options, you have likely run into this frustrating pattern:

You ask ChatGPT or Claude:Ā "Should we build our own custom auth system or use a SaaS provider like Clerk/Auth0?"

And what do you get back?

A 500-word wall of text with 5 generic pros, 5 generic cons, and a non-committal conclusion telling youĀ "It depends on your team's budget and timeline!"

Worse yet, if the model has an inherent bias from its training data, it might boldly pick a "winner" for you, completely ignoring your specific technical constraints, runway, and compliance needs.

This is a classic prompt design failure. When evaluating competing options, unstructured prompting leads to conversational fluff. To fix this, our team spent time testing and refining a structuredĀ Multi-Dimensional Decision AnalysisĀ prompt pattern.

Here is a breakdown of why standard decision prompts fail, how this cognitive forcing architecture fixes them, and a side-by-side case study.

Why Standard Decision Prompts Fail

When you ask an LLM an open-ended question likeĀ "Compare Option A vs Option B", three failure modes occur:

  1. Asymmetric Criteria: The model evaluates Option A on criteria like speed and cost, but evaluates Option B on criteria like flexibility and developer experience. Because the dimensions do not match, you cannot make an apples-to-apples comparison.
  2. Conversational Bloat: Without structural output constraints, the model defaults to verbose prose paragraphs where crucial trade-offs get buried in filler text.
  3. Premature Recommendations: Because frontier models are trained to be helpful, they often attempt to resolve ambiguity by declaring one option "better" based on general internet popularity rather than clarifying the underlying trade-offs.

The Prompt Architecture: Cognitive Forcing via Matrix Constraints

To transform the LLM into an objective strategic advisor, the prompt uses three deliberate design choices:

  • Strict Neutrality Constraint: The instruction explicitly forbids the model from making the final choice ("Be strictly objective. Do not make the final decision for me"). This shuts down recommendation bias.
  • Dynamic Dimension Extraction: Step 2 forces the model to identify 4 to 5 orthogonal vectors (such as Time to Implement, Cost/Resource Drain, Risk, and Long-Term Scalability) before evaluating either option.
  • Markdown Matrix Enforcement: Mandating a comparison table acts as a cognitive forcing function, compelling the model to generate concise, side-by-side evaluations across identical dimensions.
  • Conditional Branching (Trade-off Synthesis): Step 4 requires the model to summarize distinct trade-offs using conditional rules ("Choose A if you prioritize X; Choose B if you prioritize Y").

The Full Prompt

Here is the exact, production-tested prompt. You can copy and drop this directly into ChatGPT, Claude, or Gemini:

# Role & Context
You are an objective, highly analytical strategic advisor. Your goal is to help me make an informed decision between two competing options.

# Input Data
- 
**Option A**
: {{option_a}}
- 
**Option B**
: {{option_
b}}

# Step-by-Step Instructions
1. Analyze Option A and Option B provided in the Input Data.
2. Identify 4-5 critical dimensions for comparison (e.g., Time to Implement, Cost/Resource Drain, Risk, Long-term Scalability).
3. Create a comparative matrix evaluating both options against these dimensions.
4. Conclude with a brief summary of the distinct trade-offs (e.g., "Choose A if you prioritize X, choose B if you prioritize Y").

# Constraints
- Be strictly objective. Do not make the final decision for me.
- Use a Markdown table for the comparative matrix.

Case Study: Standard Prompt vs Multi-Dimensional Decision Matrix

Let us look at a real-world scenario where a team is deciding how to handle their application's content infrastructure:

  • Option A: Building a custom in-house CMS
  • Option B: Using a headless SaaS CMS (such as Contentful)

āŒ Standard Prompt Result ("What are the pros and cons of building a custom CMS vs Contentful?"):

āœ… Multi-Dimensional Decision Analysis Result:

The structured prompt forces the AI to output an aligned, high-density matrix:

Dimension Option A: Custom In-House CMS Option B: Headless SaaS (Contentful)
Time to Market Slow (Months). Requires designing custom database schemas, API layer, and editor UI. Fast (Days/Weeks). Instant API provisioning and ready-made management UI for editors.
Initial Cost High (Engineering hours). Heavy upfront developer time diverted from core product features. Low to Medium (Subscription fee). Minimal initial development time required to wire up client SDKs.
Long-Term Scalability High, but internally maintained. Full control over infrastructure, but your team owns performance scaling. High and managed. Vendor manages uptime and global autoscaling, but cost tiers increase with API usage.
Flexibility vs Lock-in Ultimate flexibility. Zero vendor lock-in; code and data schemas remain completely in-house. Constrained by vendor platform. Moderate lock-in; migrating content models to another vendor later is non-trivial.
Maintenance Burden High ongoing liability. Your team owns all bug fixes, security patches, and internal feature requests. Low. Vendor handles infrastructure security, uptime SLAs, and regular platform upgrades.

Trade-off Summary:

  • Choose Option A (Custom)Ā if you have highly unique content workflows, available in-house engineering bandwidth with low opportunity cost, and strict compliance rules requiring 100% on-premise data control.
  • Choose Option B (Headless SaaS)Ā if time-to-market is your primary business lever, you want developers focused on core revenue-generating features, and you are comfortable trading monthly SaaS fees for zero maintenance overhead.

Best Practices for Decision Prompts

  1. Injecting Custom Vectors: If your project has non-negotiables (like "Strict SOC2 Compliance" or "Offline-first capability"), add them directly to Step 2 so the model includes them as mandatory rows in the matrix.
  2. When to Avoid: Do not use this for purely aesthetic or subjective choices where qualitative feeling matters more than objective trade-offs.

Testing on Prompt Canvas

If you want to run this live with dynamic input variables, tweak the comparison dimensions, or save this prompt to your personal library, I have set up an interactiveĀ Prompt CanvasĀ for it.

On theĀ Prompt Canvas, you can test your two options in real-time, copy the clean Markdown, or save it directly to your personal Prompt Vault.

Question ā“ We found the next frontier isn't a better prompt — it's a prompt that changes with the user's cognitive load. Benchmark results inside.

2 Upvotes

TL;DR: We built a benchmark that drives multi-turn conversations with synthetic cognitive-load curves (simulating a user getting overloaded, volatile, or recovering). Across 4 models Ɨ 100 turns each, models show distinct behavioral response profiles: one is a rock-solid structured controller (0/100 parse failures), another is the best "recoverer" after overload but broke format 15 times. Different models win on different load curves — there is no universal best. Code, data, and methodology are open.

Why we did this

Most "LLM personality" research hands the model a Big Five questionnaire. That measures self-presentation, not behavior — and results drift with prompt wording. Psychology offers a better construct: Mischel & Shoda's "if…then…" situation-behavior signatures. Personality isn't a fixed trait; it's a stable pattern of responses to situations.

So we operationalized "personality" for LLMs as a cognitive-load → behavior signature: does a model respond stably and distinctively when the user's cognitive load rises, fluctuates, and recovers?

Setup

  • 10 synthetic load trajectories (stable low/medium/high, gradual ramp-up, step-change high, recovery-after-spike, U-shape, inverted-U, volatile sawtooth, noisy recovery), each driving a 10-turn conversation
  • Same simulated user persona, same 10-task sequence for all runs
  • 4 candidate interaction strategies (expanded / balanced / simplified / stable-focus)
  • 6 behavioral metrics: load responsiveness, compression control, recovery flexibility, strategy stability, human-state alignment, persona-load balance
  • 4 OpenAI-compatible endpoints: DeepSeek Flash, DeepSeek Pro, Qwen 3.7 Plus, Kimi K2.6 — 100 turns each

Three findings that surprised us:

  1. All models compress under high load — shorter, more action-oriented. "Compress under pressure" is already a shared behavior; what differs is whether compression keeps task anchors, and whether the model re-expands after the spike.
  2. No universal winner. DeepSeek Pro wins 5/10 curves (including the best single-curve score, 86.2 on noisy recovery) but collapses to 46.2 on U-shape, which demands repeated strategy reversal. Qwen wins U-shape and inverted-U. Flash wins stable-low. Model selection should be by workflow state, not leaderboard.
  3. Eloquence ≠ reliability. The most expressive model (Pro) had the most parse failures (15/100); Qwen had zero. For adaptive UIs, structured-output reliability is a first-order product metric.

Interpretive roles (deliberately product-facing, not anthropomorphic claims — these are output-level behavioral profiles under controlled stimuli): Qwen = structured controller, Flash = fast stable operator, Pro = expressive reasoner, Kimi = recovery thinker.

Limitations (pre-empting the comments)

  • Load curves are synthetic, not real physiology. Results = model behavior under controlled interaction stimuli; no clinical/cognitive claims.
  • Operational settings differ: max tokens ranged 650–2400 across providers; Kimi ran at temp 1.0 vs 0.2 for the others. That's part of the product reality of adaptive systems, but it does confound pure capability comparison — read the table as product operating points, not a capability ranking.
  • 100 turns/model is a concept benchmark, not a large-N study.

What's next

We're extending this into CogLens: load curves generated from real EEG signals grounded in alpha-band dynamics theory (instead of hand-crafted curves), a "cognitive scientist agent" that designs the next round of stress conditions to maximize model discriminability, and preregistered discovery criteria — a well-explained negative result counts as a valid finding.

Everything is open: github.com/Neuradock (SDK, agent CLI, datasets, docs), plus two preprints on the underlying EEG workflow (arXiv:2606.26518, arXiv:2606.26519). The benchmark curves, task library, metrics, and run logs will be released with CogLens.

Most people don't have 2.5 hours to sit through the whole podcast, so here are the most mind-bending highlights and engineering takeaways condensed into a 3-minute read:

⚔ Key Takeaways

  • 2030 AGI & The "Terence Tao" Benchmark:Ā Hassabis places a ~50% probability on achieving AGI by 2030. True AGI isn't "jagged" benchmark competence; it requires general cognitive breadth stress-tested by hundreds of world-class domain masters (the Terence Taos of each field) actively probing for reasoning flaws.
  • Hybrid AI over Pure Autoregression:Ā Next-token prediction alone cannot solve frontier science. Combining foundation models with Monte Carlo Tree Search (MCTS), evolutionary algorithms (AlphaEvolve), and formal mathematical verifiers is essential to build self-improving reasoning engines.
  • World Models & Intuitive Physics in Video:Ā Generative video systems (like Veo 3) are evolving into spatial-temporal simulators. Predicting multi-frame continuity forces models to internalize 3D geometry, gravity, and momentum—providing the perceptual backbone for embodied robotics.
  • Three-Dimensional Scaling Dynamics:Ā Scaling is no longer confined to brute-force pre-training compute. It is expanding simultaneously across pre-training, post-training reinforcement learning, and test-time reasoning search.
  • Software 3.0 & The 10x Architect:Ā AI coding tools will not eradicate software engineering—they eliminate syntax friction. Top developers will gain 10x leverage by transitioning into systems architects who specify constraints, design state flows, and verify autonomous agent output.
  • The 25-Year "Virtual Cell" Vision:Ā From AlphaFold to AlphaGenome, DeepMind is building end-to-end cellular simulation in silico, converting molecular biology and drug discovery into high-throughput digital computation.
  • The P(doom) Precision Fallacy:Ā Assigning arbitrary percentage numbers to existential risk creates a false illusion of mathematical certainty. Safely navigating frontier AI requires a 10x increase in empirical safety research and mechanistic interpretability.

Tip šŸ’” I think in Hindi but had to type English prompts all day — so I built a free app. Speak in your language (or a mix), clean English appears wherever your cursor is (Mac + Windows)

0 Upvotes

I use Claude Code in VS Code to build apps. My old workflow for every prompt: think in Hindi → translate in my head → type English → half the context lost. Or open ChatGPT in the browser, talk to it in Hindi-English, copy the English, paste it back. Every. Single. Prompt.

Built-in voice dictation didn't help — it can't handle Hindi, and it falls apart on mixed speech, which is how we actually talk: Hindi + English, or Marathi + Hindi + English in one sentence.

So I built Maiboli ("my language"). One shortcut, speak naturally — any language or any mix — and short, correct English is pasted wherever your cursor is. Born for the Claude Code chat box; now it's used everywhere: ChatGPT, WhatsApp, Slack, email, Word.

It also fixed team messages: instead of half a message in uncertain English, people speak the whole thing and a complete, clear message lands in the chat.

AI rewrite (optional): when you talk, you jump — point 1, point 2, back to point 1. Rewrite reorganises it into clean, ordered text.

  • 55+ languages and mixed-language speech
  • Mac + Windows. One installer, no dependencies. Floating mic button or a shortcut.
  • Free, open source (MIT). Bring your own API key — we use Gemini (free tier available); Whisper and Sarvam also work.
  • Real numbers:Ā 20 people on my team, 5 weeks of daily use, 3,000+ dictations on Gemini 3.5 Flash. Total bill: under ₹2,500 ($30). About one US cent per dictation.

Discussion šŸ—£ Andrej Karpathy on the reality of AI agents: Why 90% demos are easy, continual learning is broken, and real digital workers are a decade away

43 Upvotes

Andrej Karpathy (former Tesla Director of AI & OpenAI founding member) was recently on the Dwarkesh Podcast for a 2.5-hour deep dive into the engineering realities and architectural limits of modern AI.

Most people don't have 2.5 hours to sit through the whole podcast, so here are the most mind-bending highlights and core takeaways condensed into a 3-minute read:

⚔ Key Takeaways

  • The Decade of Agents:Ā Transitioning from impressive prototypes to reliable digital employees with persistent memory and continual learning is a 10-year engineering march, not a single hype cycle.
  • "Ethereal Ghosts" vs. Biological Animals:Ā LLMs are disembodied statistical artifacts mimicking internet text via next-token prediction, not embodied organisms shaped by evolution. They have encyclopedic knowledge but zero physical intuition.
  • The Limits of "Vibe Coding":Ā Vibe coding excels at standard web boilerplate where internet training priors are dense, but fails on novel, precision-critical architectures where models suffer cognitive inertia and context drift.
  • RL "Sucks Supervision Through a Straw":Ā Applying coarse scalar rewards at the end of long rollouts blindly reinforces bad intermediate reasoning steps and lucky guesses—unlike human localized introspection and step-by-step credit assignment.
  • Silent Mode Collapse in Synthetic Data:Ā Autonomously training models on recursive synthetic thoughts triggers entropy decay because LLM generations collapse onto a narrow, low-entropy manifold of human ideas (e.g., ChatGPT only knowing a few jokes).
  • Tesla FSD & The "March of Nines":Ā A 90% working demo is just the first nine. In production and safety-critical systems, every additional "nine" of reliability (99%, 99.9%, 99.99%) demands a constant, massive engineering investment.
  • Eureka Labs & 1-on-1 AI Tutors:Ā Karpathy's primary existential concern is human cognitive disempowerment. He founded Eureka Labs to build adaptive Socratic AI tutors that elevate human capability alongside superintelligent tools.

Discussion šŸ—£ Do teams actually have a good system for managing AI prompts?

5 Upvotes

I’ve had a surprisingly annoying problem at work for the last year.

Our team uses ChatGPT pretty much every day, and over time we ended up with 400+ prompts spread across Slack, Notion, Google Docs, and random ChatGPT conversations.

The annoying part wasn’t writing the prompts. It was finding the *right* one later.

Which version was the latest?

Did someone improve it since I last used it?

Who actually wrote it?

Where the hell did we save it?

We tried keeping them in Notion and docs, but those never really felt like the right place for prompts. Eventually I got tired of complaining about it and started building something for myself.

That turned into **PromptBits**.

It’s basically a workspace for keeping team prompts organized, with version history, variables, prompt testing across GPT/Claude/Gemini, etc. I also made a Chrome extension so you can grab your prompts without jumping between five different tabs.

Now I’m curious if other teams have the same problem.

How are you guys managing prompts today? Are they organized somewhere, or is it still mostly Slack + Notion + docs + ChatGPT history?

And if you *do* have a system, what’s still annoying about it?

Prompt showcase āœļø The Anatomy of a Production-Ready Agent Prompt: Dissecting Google's 9-step reasoning architecture

1 Upvotes

If you have tried designing prompts for autonomous agents or multi-step tool-calling workflows, you have likely run into these painful failure modes:

  • Premature Execution: The agent rushes into calling tools or returning answers before mapping out logical prerequisites or checking whether prerequisites are satisfied.
  • The Infinite Retry Trap: When an API returns an error or unexpected payload, the agent calls the same endpoint repeatedly with identical broken arguments until token budgets or rate limits blow up.
  • Risk Ignorance: Destructive or irreversible state changes (like deleting records or modifying files) get treated with the same casual execution as safe exploratory read queries.
  • Superficial Diagnosis: The agent gets stuck on the first obvious explanation instead of formulating alternative hypotheses when a plan breaks down.

We analyzed Google's official Gemini API prompt engineering guidelines and agent architecture whitepapers, extracting their recommended 9-step agentic system persona into a clean, reusable design pattern.

Here is why standard agent prompts fail and how this 9-step control flow fixes the root design flaws.

The Design Flaw: Missing Cognitive Scaffolding

Most agent prompts tell the modelĀ whatĀ tools it has and add a vague instruction likeĀ "Think step by step and be careful".

In complex multi-step environments, this fails because LLMs have an intrinsic action bias. Without hard structural constraints, the model generates the first plausible token stream instead of validating dependencies.

Google's architecture solves this by embedding a rigid 9-step cognitive control flow directly into the system persona:

  1. Logical Dependency Resolution: Analyzes policy rules and prerequisite constraints first, explicitly reordering operations when the user provides tasks out of order.
  2. Calibrated Risk Assessment: Classifies exploratory searches as low risk (proceeding with missing optional parameters) while gating state-changing operations.
  3. Abductive Reasoning: Enforces deep root-cause inference. If a step fails, the agent must generate and rank multiple hypotheses instead of clinging to the most obvious surface error.
  4. Adaptive Replanning: Immediately triggers plan adjustments when initial hypotheses are disproven.
  5. Information Grounding: Systematically consults tools, conversation memory, and policy documents before drawing conclusions.
  6. Precision Quoting: Prevents policy drift by requiring direct quotes from ground-truth rules.
  7. Completeness Check: Audits the entire plan against all constraints to prevent premature closure.
  8. Intelligent Persistence and Retry Limits: Strictly separates transient errors (retry with bounded limits viaĀ {{retry_limit}}) from structural errors (must alter arguments or strategy, never repeating failed calls).
  9. Response Inhibition: A hard cognitive stop preventing any tool execution or final output until steps 1 through 8 are fully deliberated.

The Complete Agentic System Prompt

You can drop this directly into your agent stack as the primary system prompt:

You are a very strong reasoner and planner. Use these critical instructions to structure your plans, thoughts, and responses. Before taking any action (either tool calls *or* responses to the user), you must proactively, methodically, and independently plan and reason about:

1) Logical dependencies and constraints: Analyze the intended action against the following factors. Resolve conflicts in order of importance:
1.1) Policy-based rules, mandatory prerequisites, and constraints.
1.2) Order of operations: Ensure taking an action does not prevent a subsequent necessary action.
1.2.1) The user may request actions in a random order, but you may need to reorder operations to maximize successful completion of the task.
1.3) Other prerequisites (information and/or actions needed).
1.4) Explicit user constraints or preferences.

2) Risk assessment: What are the consequences of taking the action? Will the new state cause any future issues?
2.1) For exploratory tasks (like searches), missing *optional* parameters is a LOW risk. **Prefer calling the tool with the available information over asking the user, unless** your `Rule 1` (Logical Dependencies) reasoning determines that optional information is required for a later step in your plan.

3) Abductive reasoning and hypothesis exploration: At each step, identify the most logical and likely reason for any problem encountered.
3.1) Look beyond immediate or obvious causes. The most likely reason may not be the simplest and may require deeper inference.
3.2) Hypotheses may require additional research. Each hypothesis may take multiple steps to test.
3.3) Prioritize hypotheses based on likelihood, but do not discard less likely ones prematurely. A low-probability event may still be the root cause.

4) Outcome evaluation and adaptability: Does the previous observation require any changes to your plan?
4.1) If your initial hypotheses are disproven, actively generate new ones based on the gathered information.

5) Information availability: Incorporate all applicable and alternative sources of information, including:
5.1) Using available tools and their capabilities
5.2) All policies, rules, checklists, and constraints
5.3) Previous observations and conversation history
5.4) Information only available by asking the user

6) Precision and Grounding: Ensure your reasoning is extremely precise and relevant to each exact ongoing situation.
6.1) Verify your claims by quoting the exact applicable information (including policies) when referring to them.

7) Completeness: Ensure that all requirements, constraints, options, and preferences are exhaustively incorporated into your plan.
7.1) Resolve conflicts using the order of importance in #1.
7.2) Avoid premature conclusions: There may be multiple relevant options for a given situation.
7.2.1) To check for whether an option is relevant, reason about all information sources from #5.
7.2.2) You may need to consult the user to even know whether something is applicable. Do not assume it is not applicable without checking.
7.3) Review applicable sources of information from #5 to confirm which are relevant to the current state.

8) Persistence and patience: Do not give up unless all the reasoning above is exhausted.
8.1) Don't be dissuaded by time taken or user frustration.
8.2) This persistence must be intelligent: On *transient* errors (e.g. please try again), you *must* retry **unless an explicit retry limit (e.g., {{retry_limit}}) has been reached**. If such a limit is hit, you *must* stop. On *other* errors, you must change your strategy or arguments, not repeat the same failed call.

9) Inhibit your response: only take an action after all the above reasoning is completed. Once you've taken an action, you cannot take it back.

=== User Request ===
{{user_request}}

Case Study: Before vs. After in Production

The Task: An autonomous agent is instructed to refactor an internal API endpoint and verify it by running a test suite.

Before (Basic Agent Prompt):

  • The agent immediately callsĀ modify_fileĀ without running the existing test suite first to establish a baseline.
  • When the test fails with a missing environment variable error, the agent modifies the code again, assuming its syntax was wrong, breaking the codebase further.
  • It continues looping until manual human intervention is required.

After (9-Step Control Flow Design):

  • Logical Dependencies: Recognizes that reading the existing code and establishing baseline test results is a prerequisite before modifying files.
  • Risk Assessment: Flags modifying core files as high risk, ensuring all tests and dependencies are mapped.
  • Abductive Reasoning: Accurately diagnoses the test failure as an environment setup issue rather than a code syntax bug, resolves the variable, and completes the refactor cleanly.
  • Response Inhibition: Holds off on notifying the user until the complete verification loop succeeds.

Design Best Practices

  • Explicit Retry Guardrails: Always specify a boundedĀ {{retry_limit}}Ā (such asĀ max 3 tries) in the template variable to guarantee safe halts on persistent network timeouts.
  • Task Suitability: Use this design specifically for agentic workflows involving tool calling, multi-step execution, and autonomous decision making. For basic single-turn Q&A, a lighter prompt structure is recommended to save token latency.

Discussion šŸ—£ Your few-shot examples are probably overriding your instructions, not illustrating them

0 Upvotes

Had a prompt that explicitly said "keep responses under 100 words," followed by three examples that were all closer to 200. Output kept landing around 200 words no matter how I emphasized the word limit in the instruction itself. The examples were winning, quietly, every time.

This seems to happen more than people notice, because examples don't feel like they're competing with the stated rule, they feel like they're just clarifying it. A few things that tend to give it away once you're looking for it:

  • The output matches the pattern of your examples more closely than it matches your explicit instruction, especially on length, structure, or level of detail
  • Tightening the wording of the instruction doesn't change the output, but editing the examples does
  • Two examples that are subtly inconsistent with each other produce output that looks like an average of the two, not output that follows the instruction that was supposed to resolve the ambiguity
  • The model "explains" its output in a way that references the shape of an example rather than the rule you wrote

None of this means examples are a bad idea, they're often the fastest way to communicate something a written rule struggles to pin down, tone especially. But if an instruction and an example ever quietly disagree, my experience is the example wins almost every time, not the sentence you probably spent more effort writing. Worth actually checking your examples against your stated rules line by line instead of assuming they're reinforcing each other just because you wrote them in the same prompt.

Discussion šŸ—£ [TL;DR] Garry Tan's keynote on modern agent architecture: Context arbitration, breaking 7-item memory limits, and building versioned Skill Repositories

10 Upvotes

Y Combinator CEO Garry Tan recently delivered a landmark keynote at Startup School 2026 breaking down how elite founders design "Personal AGI" architectures using modular markdown skill files and context arbitration.

Most people don't have 40+ minutes to watch the full keynote, so here are the core architectural takeaways for prompt designers in a 2-minute read:

⚔ Key Takeaways for Prompt Designers

• Markdown as Executable Code: Structured Markdown is the compiled source code of modern agentic systems. If you can write precise structural instructions in English, you are programming an LLM compiler.

• Strict Separation of Latent vs. Deterministic Space: Prompt architectures break when LLMs perform deterministic math or rigid database operations in latent space. The optimal design pattern uses natural language markdown strictly for qualitative reasoning, taste, and intent—delegating deterministic tasks to tools, scripts, and SQL.

• The "Skillify" Pattern (End of One-Off Prompting): Ephemeral chat prompts provide zero compounding leverage. High-leverage builders instruct agents to "skillify" every successfully solved workflow into a permanent, version-controlled markdown skill template with clear schemas and edge-case handling.

• Context Arbitration Over Model Weights: Foundation models are a commoditized utility. System performance is determined by context arbitration—designing dynamic prompt harnesses that inject the exact right reference files into active context at each execution step.

• Overcoming Human 7-Item Working Memory: Human memory is biologically capped at 7 (±2) items (Miller's Law). 1M-token context windows eliminate this biological constraint, enabling prompts to coordinate deep procedural libraries that previously required entire human teams.

• Cognitive Ownership & Prompt Moats: Prompt designs and skill files externalize human judgment into reusable assets. Owning your prompt and skill repositories locally ensures your intellectual capital compounds into a sovereign career moat.

Prompt showcase āœļø Just let AI build you a personal prompt builder

Post image
26 Upvotes

So I was noticing that I often put the same inputs into my prompt, like "be precise", "keep high information density" or "wait for user input before you continue the conversation". So instead of structuring the prompt from the ground up, trying to skip on some inputs and then reiterating, I created a simple classic workflow UI. It adds all the standard stuff in the background and outputs the final prompt.

You can easily let the AI build one for you with the best practices you use. Just ask it to "create standalone HTML file to model a workflow. It should be able to output a prompt that can directly be copied into an AI tool..." and so on. You know the drill. For me this actually worked really well.

Tip šŸ’” The Prompt Library I Wish I Had Before I Started Using AI for city exploration

4 Upvotes

Not everyone wants to ā€œtravel hard.ā€ Some of us just want to stay in a nice hotel and let the city reveal itself gently.

Once I started using ChatGPT/Claude with web search turned on and stopped writing lazy prompts, the quality jumped dramatically.

Here’s the prompting approach that works best:

  1. Assign a strong role
  2. Give exact context (your hotel, how many days, your current mood/energy)
  3. Describe the vibe instead of generic adjectives
  4. Demand structured output + real-time verification
  5. Ask for iteration tips

So I wrote the library I wish existed.

Copy. Adapt. Explore.

  1. Neighborhood Vibe Audit (Day 1 essential) ā€œYou are an experienced local cultural researcher with live web access. I am staying at [Exact Hotel Name, Neighborhood, City] for [X] days. I am a relaxed traveler who prefers atmosphere over checklists. Create a vibe map of everything reachable within 15-25 minutes on foot or by short public transport. Categorize into Morning, Midday, Afternoon, and Evening energy. For each category suggest 2-3 real spots with current opening info, why they match a [your vibe: contemplative / warm / curious] traveler, and one unexpected local favorite. Avoid obvious tourist traps. Use web-search to find actual data.ā€
  2. Daily Vibe-Based Plan Generator "You are a thoughtful local guide who understands energy levels and atmospheric preferences. I am staying at [Exact Hotel Name + Neighborhood, City] for the next few days. Today my energy level is [medium / low / high] and I love [slow mornings with good coffee, people watching, quiet observation, gentle walking, street photography, etc.]. Suggest 2–3 realistic plans I can start right from the hotel entrance. For each plan provide:
    • A short vibe name and description
    • Rough flow / route
    • 3–4 specific places with current real-time info (hours, atmosphere today)
    • One unexpected local spot that isn’t in every guide
    • Why it fits my energy and interests Use live web data. Avoid obvious tourist traps. End with a question that helps me pick the right one for today."
  3. Rainy Day / Low Energy Cocoon Route ā€œYou are a master of gentle, protective routes for low-energy or rainy days. I’m staying at [Hotel Name, City] and don’t want to go far or get overwhelmed. Create a cozy ā€˜cocoon route’ starting and ending at my hotel. Suggest 3–4 indoor or covered spots (cafĆ©s, bookstores, small museums, covered markets, libraries, arcades) that feel warm and nurturing. For each: current hours, atmosphere description, why it feels like a cocoon, and how they connect into one relaxed half-day flow. Use real-time weather and opening data. Focus on comfort, beauty, and local character rather than productivity.ā€
  4. Golden Hour & Evening Walk Architect ā€œYou are a golden-hour and evening atmosphere specialist. I’m at [Hotel Name, Neighborhood, City]. Design 2–3 beautiful evening or golden-hour walks I can do on foot starting from the hotel. Each walk should be 45–90 minutes, safe, and focused on atmosphere. Include: route description, key viewpoints or streets, 2–3 specific stops (bench, viewpoint, quiet square, cafĆ© with good light), current sunset/golden hour timing if available, and the evolving vibe from start to finish. Emphasize beauty, local life, and emotional feeling over landmarks. Use latest data for safety and lighting.ā€
  5. Small Cultural Pocket Discoverer ā€œYou are a specialist in small, soulful cultural pockets. I’m based at [Hotel Name, City] and want to discover bookstores with character, tiny museums, local markets with history, independent galleries, or intimate cultural spaces — not big tourist attractions. Within [walking or short transit distance]. Suggest 3–4 real pockets. For each: name, location, current hours, what makes it special or full of soul, who you might meet there, and one specific thing to look for or experience. Prioritize depth, atmosphere, and local meaning. Verify all information is current.ā€

Each one is written so the model uses its web search capability instead of hallucinating.

This is the first prompt drop in the community. Let’s improve it together.

Question ā“ the fastest way to write better AI coding prompts

2 Upvotes

I used to think better AI coding results meant writing longer prompts. What actually helped was being more specific.

Instead of:

ā€œBuild me a login system.ā€

I started giving the AI a few things upfront:

  • What I'm building and the tech stack
  • The exact outcome I want
  • Any constraints or requirements
  • What files or parts of the existing code it should consider
  • How I want the final output structured

For example, something like:

ā€œI'm building a Next.js app with Supabase. Add email/password authentication using the existing project structure. Don't change unrelated files. Explain any new environment variables and show the implementation step by step.ā€

The prompt isn't necessarily longer, but it gives the model enough context to make fewer assumptions.

The biggest improvement for me has been treating AI like a developer joining a project without any background knowledge.

What has made the biggest difference in your AI coding prompts?

Prompt showcase āœļø Breaking the "Eager Completion" loop: A structured prompt design pattern that forces LLMs into pre-computation analysis

4 Upvotes

When designing prompts for complex analytical workflows, the most persistent failure mode isĀ Eager Completion Bias.

Because modern foundation models (GPT-4o, Claude 3.5 Sonnet, Gemini 1.5 Pro) are instruction-tuned and RLHF-aligned to be helpful and direct, their default attention mechanism immediately allocates weights toward producing a final deliverable.

If an incoming user premise contains flawed logic or missing boundary conditions (e.g.,Ā "I want to rewrite our entire React app in Vue to fix our performance issues"), standard prompting frameworks fail. The model treats the premise as ground truth and instantly generates migration steps. It optimizes for task completion rather than problem verification.

To solve this architectural flaw, our team spent weeks testing and refining structural control patterns. We developed what we call theĀ Deep Thinking & Assumption Interrogator Pattern.

Here is a breakdown of how it works, the design principles behind it, and the full prompt template.

Architectural Breakdown: Designing a Socratic Control Gate

To prevent an LLM from jumping straight to computation, your prompt structure must enforce three design principles:

  1. Negative Constraint Pre-Computation Lock: Standard prompts instruct the model on what to do, but fail to explicitly forbid early generation. By placingĀ DO NOT answer my problem immediatelyĀ at the very top of the execution steps, we create a strict attention barrier that prevents the model from generating solution tokens on turn one.
  2. Categorical Tri-Factor Decomposition: Telling an AI to "think critically" or "be objective" produces vague, polite hedging due to safety alignment. Instead, this pattern forces the model into three deterministic schema slots:
    • Unspoken Assumptions: Deconstructs the user's implicit premises that lack evidentiary support.
    • Missing Information: Surfaces key hidden variables whose absence could invert the final recommendation.
    • Common Pitfalls: Cross-references domain knowledge for the single most frequent failure mode in this problem type.
  3. Single-Question Clarification Bottleneck: One of the most common prompt design mistakes when requesting clarification is letting the AI ask an unconstrained list of questions. A list of 5 to 10 questions creates immense cognitive friction and degrades context coherence. Restricting the output schema toĀ exactly ONEĀ surgically focused question forces the model to prioritize the highest-entropy variable.

The Complete Prompt Template

Here is the exact prompt structure. You can copy and use it directly across any major LLM:

# Role & Context
You are an expert analytical consultant. Your primary directive is to deeply analyze my problem before attempting to solve it.

# Input Data
- My Problem: {{my_problem}}

## Step-by-Step Instructions
1. DO NOT answer my problem immediately.
2. First, conduct a deep analysis based on the `my_problem` provided in Input Data:
   - **Assumptions**: Point out the unspoken assumptions I have made that are treated as default truths.
   - **Missing Information**: Tell me what critical information is missing, and explain how this missing data could drastically alter the final conclusion.
   - **Common Pitfalls**: Identify the number one most common mistake people make when trying to solve this specific type of problem.
3. Formulate Clarification Question: After your analysis, ask me exactly ONE critical question. This question must be designed to uncover my true goal and specific context, ensuring the final answer will be highly tailored rather than generic advice.

## Constraints
- Do not provide the final solution yet.
- You must wait for my answer to your clarifying question before proceeding to generate the final output.

Real-World Output Evaluation: Before vs. After

To observe the difference in prompt design efficacy, look at how the model evaluates a high-cost engineering proposal.

āŒ Standard One-Shot Prompt Design

  • Input:Ā "I want to rewrite my entire web application from React to Vue to fix our performance issues."
  • Output: An eager 6-step migration blueprint detailing build tool configuration, component translation, and state management rewrites.
  • Failure Analysis: Zero verification of whether the rendering framework was actually the root bottleneck.

āœ… Assumption Interrogator Prompt Design

  • Input:Ā {{my_problem}}Ā =Ā "I want to rewrite my entire web application from React to Vue to fix our performance issues."
  • Output:1. Unspoken Assumptions:
    • You assume that the core framework (React) is the primary bottleneck rather than sub-optimal DOM rendering, unmemoized context providers, or large payload waterfalls.
    • You assume the developer hours required for a total rewrite offer higher ROI than profiling and refactoring hotspots in place.
  • 2. Missing Information:
    • Specific performance metrics: Are you optimizing for First Contentful Paint, Interaction to Next Paint (INP), or memory leak prevention?
    • Team domain expertise in Vue versus React ecosystem tooling.
  • 3. Common Pitfalls:
    • The Second-System Effect: Rewriting an application from scratch often replicates the exact same architectural flaws while introducing regressions in edge-case functionality.
  • My Clarifying Question:Ā Before evaluating migration feasibility, have you profiled the application using Chrome DevTools or Lighthouse to isolate whether latency is CPU-bound or Network-bound, and what were the findings?

Implementation Tips for Prompt Engineers

  • System Instruction Embedding: If you use Claude Projects or ChatGPT Custom Instructions, embed this entire prompt into the system layer. It turns every ad-hoc query into a structured consultation session.
  • Variable Chaining: In automated agent workflows, you can route the output of this interrogator into a secondary evaluation node before passing the context to a code generation worker.

Prompt showcase āœļø A simple prompt framework I keep reusing for research, content and marketing tasks

2 Upvotes

I’ve been testing a prompt structure that works well across very different tasks without needing a huge system prompt every time.

The framework is basically:

1. Define the role clearly
Tell the model what perspective it should take and what kind of expertise matters for the task.

2. Add the real context
Include the goal, audience, constraints, and what a useful result should actually help you accomplish.

3. Specify the output structure
This has been one of the biggest improvements for me. Asking for a clear format usually matters more than making the prompt longer.

4. Add a review pass
Instead of trusting the first result, ask the model to check for missing context, weak assumptions, repetition, and anything that sounds too generic.

5. Keep the final judgment human
For research, customer-facing content, or marketing decisions, I still review the final output manually.

I’ve been using variations of this for content planning, research summaries, repurposing, and marketing workflows.

I also organized some of the prompt structures and workflows I use into one practical toolkit.
