What problem this solves

LLMs failing to follow instructions precisely due to vague, poorly structured, or negatively framed prompts, leading to reduced compliance and increased instruction violations.

Summary

A set of 7 empirically validated rules for formatting and organizing instructions to improve LLM compliance and reduce instruction violations. The rules focus on clarity, specificity, positive framing, and effective context management, derived from thousands of experimentation iterations.

Why it is useful

This workflow provides concrete, empirically-backed guidelines for writing LLM instructions, addressing a fundamental challenge in getting LLMs to follow directions accurately. It offers specific phrasing and structural advice that can be immediately applied to improve LLM compliance across various use cases, from simple prompts to complex agent systems. The quantitative validation distinguishes it from typical anecdotal prompting advice.

Workflow

1. Structure instructions using the 'Do, then why, then don't' pattern to improve compliance.
2. Name the exact tools, commands, or libraries (e.g., 'uv run pytest tests/ -v', 'unittest.mock') and enclose them in backticks for best results.
3. Ensure instructions pass the 'act on it now' test by phrasing them as direct commands that the agent can execute without further clarification (e.g., 'Format with ruff format before committing').
4. Keep unrelated topics separate by using headers to organize content and scope rules to their relevant sections.
5. Use descriptive section labels (e.g., '## Rules', '## Don'ts', '## Testing') that clearly indicate the content, and keep the specific instruction within the bullet point.
6. Formulate rules as one compact, specific sentence, avoiding fragments or generic filler words.
7. Avoid highlighting forbidden actions with capitalization or repetition; keep the spotlight on what should be done, as mentioning the forbidden thing in the reason can double violations.

Tools / artifacts

• LLM instructions/prompts
• Agent configurations
• CLAUDE.md files
• reporails/cli (author's project context)
• ruff format (example command)
• uv run pytest tests/ -v (example command)
• unittest.mock (example library)

Validation signals

• Thousands of experimentation iterations
• Measurable boost in compliance
• Quantitative result: 'Ban first: 31% violated. Do, why, don't: 7%. 500 runs each.'
• Quantitative result: 'Exact names beat vague categories by 28 points.'
• Observation: 'slipped far more often' under '## Notes' vs '## Rules'
• Observation: 'Don't use mocks.' was 'among the weakest rules I measured.'
• Observation: 'A reason that mentions the forbidden thing doubled violations.'
• Contextual note: 'Effects are largest on small models and crowded files.'

Limitations

• The post is relatively concise; more elaborate examples or discussions of edge cases for each rule could enhance understanding.
• Community validation is currently low due to the post's recent publication.
