What this skill tells your AI
The instructions your AI receives, as published by haabe/mycelium in tests/bash/fixtures/check_31/present/plugins/mycelium/skills/goodskill/SKILL.md and read by ahel’s review.
This skill writes to .claude/canvas/purpose.yml (Update canvas/purpose.yml).
Preflight: Read target canvas file
Before any canvas write, this skill reads the target file first per the Read-before-Write hard rule (anti-pattern #7 instance #5 prevention).
Read .claude/canvas/purpose.yml (limit: 1 for Edit, full Read for Write)
Then proceeds with the write.
