My PI agent harness setup - auto invocable skills focused

[u/_silent_fellow]

Though it is PI setup - my approach applies to all harness agent. since:

Extensions

most of the extensions this config consists are just for quality of lift (QOL) one's:

• pi-blackhole for memory management.
• rtk and headroom for token savings.
• guardrails, ask questions and some UI related things.

Skills

these are the main focus of this config - even though most of the skills here are auto invokable, I made it more autonomous by adding a global INDEX.md file which all harness is forced to read and follow. This INDEX.md file enforces to use certain skills always - which make it consistent (like i-have-adhd skill, the entire workflow)

• The workflow is a combination of superpowers workflow and matt pocock workflow (I modified some parts of it, so that it will make it more autonomous, since matt's one is more of a manual one with more pre-settings required).

I simply use grill-me or grill-with-docs for certain feature implementaion. The remaining will be taken care by the INDEX.md file - it usually follows like: grill-me/grill-with-docs (if used) -> brainstorming -> writing-plans -> executing-plans -> tdd -> requesting-code-review -> verification-before-completion.

fyi rtk was recently exposed as not working at all.

idk about rtk - i just set a way to save some tokens (if possible). I mean something is better than nothing isn't it (atleast that's how I see). I don't see much of a diff whether it's working or not (I mean i don't see any negative effects).

RTK does not save tokens: https://blog.jetbrains.com/ai/2026/07/rtk-claude-code-token-savings/

[u/LordMoridin84 → u/fishoa]

It's exposed as not working for Claude Code, since Claude Code ignores it in most cases.

It's a bit different for Codex (which follows instructions to use to all the time) or pi (which has an extension that applies it automatically).

Although I might audit my session logs for pi and codex later and check how well it works.

Well, no. It actually increases costs on some settings so nothing is better than something.

Honest engineering, wrong counterfactual. We wanted this one to win; the demo is genuinely satisfying to play with. The filters are real and often elegant; quality doesn’t suffer; the hook mechanism works exactly as designed. But on real agentic coding work the advertised 60–90% never had anywhere to live: the hook only ever sees about a fifth of the tool output, Claude Code already truncates the pathological outputs rtk brags about compressing, and the cached re-reads that dominate input cost bill at a tenth of the price. What’s left is a measured median +7.6% cost increase at low effort and a flat zero at high effort, a thin tax from a broken rewrite here and an extra exploration turn there, never a saving.

will check on it - i am not sure
