Analyze the current branch's diff against its merge-base with main.
/diff # Stat overview (default)
/diff full # Full patch output
/diff files # List changed files only
/diff commits # List commits on this branch
/diff overlap feature/other-branch # Check for file overlap with another branch
# CORRECT — only shows YOUR changes
git diff $(git merge-base main HEAD)..HEAD
# WRONG — includes main's forward progress as noise
git diff main
| Argument | Action |
|---|---|
stat or (empty) | git --no-pager diff $(git merge-base main HEAD)..HEAD --stat |
full | git --no-pager diff $(git merge-base main HEAD)..HEAD | head -200 |
files | git --no-pager diff $(git merge-base main HEAD)..HEAD --name-only |
commits | git --no-pager log $(git merge-base main HEAD)..HEAD --oneline |
overlap <branch> | Cross-branch file overlap check (see below) |
BRANCH_A_FILES=$(git --no-pager diff $(git merge-base main HEAD)..HEAD --name-only)
BRANCH_B_FILES=$(git --no-pager diff $(git merge-base main <other-branch>)..<other-branch> --name-only)
# Show files that appear in both
comm -12 <(echo "$BRANCH_A_FILES" | sort) <(echo "$BRANCH_B_FILES" | sort)

Route a codebase question to the right tool — structural graph, semantic search, or risk analysis. Use when you need to find or understand code without knowing exact file names.

Auto-configure CLAUDE.md and claude/ knowledge docs for a new project. Use when setting up Brain Bootstrap in a new repository. Discovers the codebase, fills in templates, and writes project-specific configuration.

Use before any new feature, component, or behavioral change — when you need to explore requirements and design before writing code

Activate safety guards for the session. Use /careful before critical operations — blocks rm -rf, DROP TABLE, git push --force, kubectl delete namespace, docker system prune via PreToolUse hook.

Generate a user-facing changelog from git commits — categorize, filter noise, translate to user language. Runs in isolated fork context.

Save session state before context gets full or before ending. Writes current task state, branch, and loaded docs to claude/tasks/todo.md so the next session can resume cleanly.
