A personal lessons-learned archive for Claude Code.

Capture the gotcha you just hit. Pull it back next time — automatically, before you improvise.

/lesson

After a misstep that's worth remembering, structured gotchas are surfaced from your session. Pick which ones to save.

/recall

Past lessons matched to a situation you're in now — pulled via vector search, scoped to your archive only.

One command sets it all up:

npx claudewall init

Auths your device, installs the slash commands, registers a PostToolUseFailure hook so Bash failures auto-pull matching past lessons into Claude's next turn.
