Keeps a persistent LOGBOOK.md in your project root as high-signal institutional memory (findings, decisions, root causes, regressions).

• Mention logbook with entry text to record an event (the skill formats it with a date header, timestamp, and tags).
• Mention logbook review to summarize the current logbook without writing a new entry.

Tip: For better triggerability, document this skill’s usage in your repo instructions (e.g. AGENTS.md, CLAUDE.md, etc.).

See SKILL.md for the full rules and entry format.
