re0-memo — скилл для Claude Code: уроки из рабочего цикла

name: re0-memo
description: "Turn a finished, failed, or disappointing work cycle into portable lessons, anti-patterns, quality gates, and next-cycle vocabulary. Use after a build, QA pass, demo, user complaint, or abandoned attempt when the useful output is what the next pass must learn rather than the code itself."
---

Turn a completed cycle into lessons the next cycle can actually use.

## Goal

`re0-memo` extracts durable learning from a work cycle without defending the artifact that produced it. A cycle can run, pass tests, and still be the wrong thing. The output is not a changelog or therapy note: it is a local, evidence-backed record of what worked, what misled the build, and what gate the next pass must clear.

Use `re0-memo` when the artifact is done, failed, disappointing, or ambiguous enough that the next agent needs the cycle's lessons more than its momentum.

## Workflow

1. Read the original objective, final artifact, QA evidence, user complaints, and any local planning notes.
2. Separate working assets from misleading progress: contracts, schemas, tests, services, vocabulary, and examples that earned reuse vs. UI, panels, scaffolds, or abstractions that only looked productive.
3. Generalize before recording: when feedback arrives as many specific complaints, cluster them upward into the shared pattern before writing anything down — many specifics against many items usually share one root gap. Record the root and its pattern family as the lesson; keep the specifics under it as evidence, not as lessons themselves.
4. Name each failure as an anti-pattern, not a mood.
5. Convert repeated or high-impact failures into quality gates for the next pass.
6. Convert vague user direction into architecture vocabulary a fresh agent can use.
7. Write or refresh local docs for the cycle: a re0-memo for lessons and a plan for next-cycle contracts, gates, and vocabulary.
8. Verify that a from-scratch agent could avoid the same failure from those docs alone.

## Rules

- Do not defend the artifact. If it missed the product, say what missed.
- Do not write a changelog. File lists and effort summaries are not lessons.
- Do not transcribe a specific complaint as a lesson. A lesson that only fixes the reported case keeps the system human-in-the-loop: the same class of failure returns anywhere a person didn't point. Escalate every specific to the pattern that catches its whole class — the reporter's exact words are evidence, not the gate.
- Preserve negative corpus. Failed paths are training data.
- Prefer hard gates over advice.
- Cite evidence from the cycle: objective, file facts, QA output, screenshots, transcripts, diffs, or user feedback.
- If the next agent cannot act on it, it is not a lesson yet.
- Keep provenance local; shipped artifacts should not narrate their scars.

## Verification

Before finishing:

1. Every lesson traces to observed cycle evidence.
2. Every anti-pattern names a concrete failure mode and the gate that catches it.
3. No lesson is a single reported case in disguise: each covers a class, with the specifics that raised it sitting under it as evidence.
4. A fresh agent can tell what to preserve, what to discard, and what to test first without reading the whole old session.
