Use when the user asks for a review, before creating a PR, or when re-checking a diff that answers earlier review findings. Do not use after ordinary edits, and do not use for routine branch review — the built-in /code-review covers that.
context-compactor
Analyzes and compacts context-affecting documents (project memory, CLAUDE.md, skill files) to reduce token usage and compaction frequency. Manual trigger only. Always requires user approval before making changes.
doc-rules

Writes Conventional Commits messages with a Japanese explanation. Do not use to merely inspect git status or a diff.
handoff
Session migration for context corruption recovery. Writes a fact-based handoff file so work can continue in a fresh session, or resumes from one. Manual trigger only (`/handoff`).

journal-manager
Writes and maintains work journals under WORK/ in the Obsidian vault. Use after an experiment or analysis produces a reading that has no permanent home yet, and when consolidating or promoting existing journals. Do not use for ordinary implementation work, progress logs, or findings that already have a destination.
knowledge-manager
Records and retrieves the AI_KNOWLEDGE base in the Obsidian vault (patterns, troubleshooting, best practices).
