Correct

A class is a mistake that happened twice. Fix it where it can never happen again.

Before anything else: read $HOME/.agentic-workflow/toolkit/skills/_preamble.md and follow it (skill index, provider capability map, bootstrap check, session context). Run its Session Close section when this skill finishes.

Steps

1. Find the repeats. Look through this session and recent ones in this repo for human corrections that point at the same mistake. Count both kinds: the approach or design was wrong ("no, wrong file", "you missed", "don't use that"), and the process was wrong (it belongs in CI, in another doc or tool, or in a different order of steps). Judge by what the human meant, not by trigger words. A class needs at least two corrections from two different sessions on two different days.
2. Name the class. One sentence: what the agent did, and what it should have done.
3. Pick the highest level that works, in this order:
   1. Architecture: make the mistake impossible to express.
   2. Types: make the compiler refuse it.
   3. Lint: an error message that names the fix.
   4. Test: a failing test for the past mistake.
   5. Docs: last, only when nothing above can enforce it.
4. Prove it. Say which past correction the check would have caught. If it would not have caught one, it is the wrong level.
5. Report. Print the class, the level, the proposed change (files and a description, not a patch) and the evidence. Do not edit any file.
6. Record. End with: "sindri evolve correct runs this weekly over this repo's transcripts."
