Command

/lessons

Load, view, and save project lessons from tasks/lessons.md. Works on ALL platforms — Claude Code, Windsurf, Cursor, Codex, Antigravity, OpenCode.

Run:/lessons

/lessons — Project Self-Improvement

Cross-platform command for the Compound Learning System. Works everywhere, with or without hooks.

Usage

/lessons              → load and show all lessons for this session
/lessons save         → extract corrections from this session and write to tasks/lessons.md
/lessons add "<rule>" → add a manual rule immediately
/lessons clear        → show lessons and ask which to remove

What This Command Does

/lessons (no args) — Load lessons

  • Check if tasks/lessons.md exists in the project root
  • Read all lesson rules (lines starting with -)
  • Inject them as PROJECT LESSONS — HARD RULES for this session
  • Print a summary of how many rules are active
  • Apply them immediately — do not wait for another message
If tasks/lessons.md does not exist yet, say: > "No lessons file found. Corrections you give me this session will build it. Run /lessons save at the end of the session to write them."

/lessons save — Capture session corrections

Scan the current conversation for user corrections:

  • Phrases matching: "no don't", "use X instead", "stop doing Y", "wrong approach", "we always", "we never", "I told you", "that's not how we", "use X not Y"
  • Extract each as a plain-language rule
  • Show the extracted rules to the user before writing
  • Ask: "Write these N rules to tasks/lessons.md?"
  • On confirmation: create tasks/ if needed, append rules with today's date

/lessons add "" — Add a manual rule

Immediately append the rule to tasks/lessons.md: 

## 2026-05-06

  • <rule>
    •
Confirm: "Rule added. It will be active from the next session (or reload with /lessons)."

/lessons clear — Review and prune

Show all current rules numbered. Ask: "Which numbers to remove? (e.g. 1,3,5 or 'all')" Remove selected lines and rewrite the file.

Format of tasks/lessons.md
