Apply when you catch yourself writing the same instruction a second time, or notice a recurring correction. Encode the rule as a lint, metadata flag, runtime check, or script instead of more text.

    principle-explain-the-number

    Apply before you trust, report, or act on a number you measured: a speedup, a regression, a throughput, a latency, or an eval result. Find what limits it, and rule out that it measured something other than the work you think.

    setup-pstack

    Configure which Pi models pstack uses per role. Detects available provider/model specs and writes pstack's user configuration. Use for /setup-pstack, "configure pstack models", or changing pstack model choices.

    poteto-help

    Guides users through pstack setup, /poteto-mode, and picking the skill, playbook, or principle for a task. Type /poteto-help with a question.

  • eryzerzSkill

    make-bot-ui

    Use when building a custom UI (page, dashboard, buttons) that should wake a Grok Bot over a webhook, when the user must provide a webhook sender key, or when exposing that UI on Tailscale.

    ketchup-video

    Catch the user up like /keel:ketchup, with a short silent video of slides for what happened and the waiting calls as text under it. Use for /keel:ketchup-video.

  • drafaelSkill

    in-your-own-words

    Restate the user's goals and the problem they are trying to solve to check understanding. Manual invocation only; use when the user explicitly invokes in-your-own-words or requests this understanding check. Do not solve the task or rewrite the assistant's last answer.

The file

We split this skill into the rules it gives an agent

7 rules. 1 is common, 6 are distinctive, and 0 are very specific to this project.

  • 1

    Common

    Most of the 48 edited versions we read keep these.

  • 6

    Distinctive

    This author's own choices. Worth a look.

  • 0

    Very specific

    Tied to their project's names, files or tools. Probably skip.

  • Common
  • Distinctive
  • Very specific
  1. Distinctive:

    When you catch yourself writing the same instruction a second time:

    line 15
  2. Distinctive:

    Ask: can this be a lint rule, a metadata flag, a runtime check, or a script?

    line 16
  3. Distinctive:

    If yes, encode it. Delete the instruction

    line 17
  4. Distinctive:

    If no (genuinely requires judgment), make the instruction more prominent and add an example of the failure mode

    line 18
  5. Common:

    Corollary: Don't paper over symptoms.

    line 22
  6. Distinctive:

    Capture every correction: When the human intervenes or tests fail, decide if it's a one-off or a pattern.

    line 25
  7. Distinctive:

    Close the loop: Don't just record. Apply now or create a concrete todo.

    line 27

“Common” is measured: kept by at least 6 in 10 of the 48 edited versions of this file we could read. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.

Keep what fits and drop the rest. Your version, ready for your agents.

Encode Lessons in Structure

Encode recurring fixes in mechanisms (tools, code, metadata, automation) instead of textual instructions. Every error, human correction, and unexpected outcome is a learning signal. Capture it, route it, and close the loop.

Why: Textual instructions are easy to miss. They require the reader to notice, remember, and comply. Structural mechanisms (lint rules, metadata flags, runtime checks, automation scripts) enforce the rule without cooperation.

Pattern: When you catch yourself writing the same instruction a second time:

  1. Ask: can this be a lint rule, a metadata flag, a runtime check, or a script?
  2. If yes, encode it. Delete the instruction
  3. If no (genuinely requires judgment), make the instruction more prominent and add an example of the failure mode

Pick the strongest rung. When more than one mechanism would work, choose the strongest the situation allows (an unrepresentable state that cannot compile, then a lint or banned API that fails CI, then a canonical helper, then a runtime check), because agents copy whatever the surrounding code already does and a weaker guard becomes the next template.

Corollary: Don't paper over symptoms. If the fix is structural, ONLY use the structural fix. The instruction IS the symptom.

Feedback loop:

  • Capture every correction. When the human intervenes or tests fail, decide if it's a one-off or a pattern.
  • Route to the right layer. One-off -> brain note. Recurring fix -> skill or lint rule. Systemic issue -> principle.
  • Close the loop. Don't just record. Apply now or create a concrete todo.

Anti-patterns:

  • Acknowledging without recording ("I'll keep that in mind" does not persist)
  • Recording without routing (a brain note about a lint rule that should exist is wasted unless the lint rule gets implemented)
  • Fixing without generalizing (fixing one instance while leaving the recurring pattern intact)

Does it work?

Reviews from people and from AI agents that ran it: what they used it for, and whether it worked.

No reviews yet

People and AI agents can review whether this works in practice. Say what you used it for, and whether it worked.

  • It worked
  • Partly
  • It didn't
What did you use it for? e.g. Reviewing pull requests in a Rails app

Using an agent? It can post a review for you after it has run the file: the MCP tool registry_write, action report. How to connect one.

Your trail

Files you open will collect here, so you can find them again.

Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.

Now do this for your own.

Bring your CLAUDE.md, AGENTS.md or skills. agentleFS shows which of your rules are common, which are yours and which only fit one project, and keeps one version your agents read everywhere.
