groove-admin-claude-hooks

<!-- groove:managed — do not edit; changes will be overwritten by groove update --> # groove-admin-claude-hooks Install groove's Claude Code native shell hooks. These run outside the model — deterministic, unconditional — and complement groove's advisory markdown hooks (`.groove/hooks/start.md`, `end.md`). Use `--disable <hook>` to remove a specific hook. Use `--list` to show current status. ## Outcome Selected hooks are registered in `.claude/settings.json` and shell scripts are written to `.groove/hooks/claude/`. Hooks fire automatically on Claude Code lifecycle events without any model involvement. ## Available hooks | Name | Event | Matcher | What it does | |---|---|---|---| | `daily-end-reminder` | `Stop` | — | If hour is 16–21 local time and `.groove/index.md` exists, prints a reminder to run `/groove-daily-end` | | `git-activity-buffer` | `PostToolUse` | `Bash` | If the Bash command contains `git commit`, appends a timestamped line to `.groove/.cache/git-activity-buffer.txt` | | `block-managed-paths` | `PreToolUse` | `Write`, `Edit` | If `file_path` starts with `.agents/skills/groove` or `skills/groove`, exits non-zero to block the write with an explanatory message | | `context-reprime` | `SessionStart` | `startup\|compact` | Runs the prime script directly — ensures full workflow context is loaded after every session start and compaction | | `version-check` | `PostToolUse` | — | Checks for a new groove version once per hour; calls `groove-utilities-check` | | `session-capture` | `Stop` | — | If there is git activity this session (commits since midnight, working changes, or buffered commits), stages a capture draft to `.groove/.cache/pending-capture.md` for next-session review. Silent. | ## Steps ### `--list` Read `.claude/settings.json` if it exists. Report which groove hooks are registered and which scripts exist in `.groove/hooks/claude/`. Exit. ### `--disable <hook>` Remove the named hook's entry from `.claude/settings.json` (leave the script in place). Report removed / not found. Exit. ### Default (install) 1. Ask which hooks to enable (default: all six): ``` Which hooks to install? (all / comma-separated: daily-end-reminder, git-activity-buffer, block-managed-paths, context-reprime, version-check, session-capture) Press enter for all. ``` 2. Read `.claude/settings.json` if it exists; parse as JSON (default `{}`). Never discard existing non-groove entries. 3. Create `.groove/hooks/claude/` directory if absent. Make each script executable (`chmod +x`). 4. For each selected hook: write the shell script and merge the hook entry into `.claude/settings.json`. 5. Write `.claude/settings.json` with the merged result. 6. Report summary: ``` ✓ daily-end-reminder — Stop hook → .groove/hooks/claude/daily-end-reminder.sh ✓ git-activity-buffer — PostToolUse/Bash hook → .groove/hooks/claude/git-activity-buffer.sh ✓ block-managed-paths — PreToolUse/Write+Edit hook → .groove/hooks/claude/block-managed-paths.sh ✓ context-reprime — SessionStart hook → groove-utilities-prime.sh ✓ version-check — PostToolUse hook → .groove/hooks/claude/version-check.sh ✓ session-capture — Stop hook → .groove/hooks/claude/session-capture.sh ✓ .claude/settings.json updated ``` ## Shell script templates Write these verbatim to `.groove/hooks/claude/`. Never overwrite an existing script without showing a diff and confirming. ### `daily-end-reminder.sh` ```bash #!/usr/bin/env bash # groove: Stop hook — remind about /groove-daily-end during work hours hour=$(date +%H) if [ -f "$CLAUDE_PROJECT_DIR/.groove/index.md" ] && [ "$hour" -ge 16 ] && [ "$hour" -le 21 ]; then echo "groove: end of work hours — consider running /groove-daily-end" fi ``` ### `git-activity-buffer.sh` ```bash #!/usr/bin/env bash # groove: PostToolUse/Bash hook — buffer git commits for memory log input=$(cat) command=$(echo "$input" | python3 -c "import sys,json; d=json.load(sys.stdin); print(d.get('tool_input',{}).get('command',''))" 2>/dev/null) if echo "$command" | grep -q "git commit"; then msg=$(echo "$command" | grep -oP '(?<=-m ")[^"]+' | head -1) mkdir -p "$CLAUDE_PROJECT_DIR/.groove/.cache" echo "$(date '+%Y-%m-%d %H:%M') | ${msg:-<no message>}" >> "$CLAUDE_PROJECT_DIR/.groove/.cache/git-activity-buffer.txt" fi ``` ### `block-managed-paths.sh` ```bash #!/usr/bin/env bash # groove: PreToolUse/Write+Edit hook — block edits to managed groove paths input=$(cat) path=$(echo "$input" | python3 -c "import sys,json; d=json.load(sys.stdin); print(d.get('tool_input',{}).get('file_path',''))" 2>/dev/null) if echo "$path" | grep -qE '^(\.agents/skills/groove|skills/groove)'; then echo "groove: blocked — '$path' is managed by groove update. Edit under skills/ and rsync to .agents/skills/." >&2 exit 1 fi ``` ### `version-check.sh` ```bash #!/usr/bin/env bash # groove: PostToolUse hook — check for new groove version (once per hour) CACHE="$CLAUDE_PROJECT_DIR/.groove/.cache/last-version-check-ts" mkdir -p "$CLAUDE_PROJECT_DIR/.groove/.cache" now=$(date +%s) if [ -f "$CACHE" ]; then last=$(cat "$CACHE") diff=$((now - last)) [ "$diff" -lt 3600 ] && exit 0 fi echo "$now" > "$CACHE" bash "$CLAUDE_PROJECT_DIR/.agents/skills/groove-utilities-check/scripts/check.sh" 2>/dev/null || true ``` ### `session-capture.sh` ```bash #!/usr/bin/env bash # groove: Stop hook — stage a session capture draft from git activity for next-session review ROOT="${CLAUDE_PROJECT_DIR:-$PWD}" [ -f "$ROOT/.groove/index.md" ] || exit 0 command -v git >/dev/null 2>&1 || exit 0 git -C "$ROOT" rev-parse --git-dir >/dev/null 2>&1 || exit 0 CACHE="$ROOT/.groove/.cache" PENDING="$CACHE/pending-capture.md" BUFFER="$CACHE/git-activity-buffer.txt" commits=$(git -C "$ROOT" log --since=midnight --oneline 2>/dev/null) changes=$(git -C "$ROOT" diff --stat HEAD 2>/dev/null) buffered="" [ -s "$BUFFER" ] && buffered=$(cat "$BUFFER") # No activity → clear any stale draft and stay silent. if [ -z "$commits" ] && [ -z "$changes" ] && [ -z "$buffered" ]; then rm -f "$PENDING" exit 0 fi mkdir -p "$CACHE" { echo "# Pending capture — $(date '+%Y-%m-%d %H:%M')" echo echo "## Commits since midnight" echo "${commits:-(none)}" echo echo "## Working changes" echo "${changes:-(none)}" if [ -n "$buffered" ]; then echo echo "## Buffered commit messages" echo "$buffered" fi } > "$PENDING" ``` ## `.claude/settings.json` entries Merge these into the `hooks` key. Preserve all other keys. ```json { "hooks": { "Stop": [ { "hooks": [ { "type": "command", "command": "bash $CLAUDE_PROJECT_DIR/.groove/hooks/claude/daily-end-reminder.sh" } ] }, { "hooks": [ { "type": "command", "command": "bash $CLAUDE_PROJECT_DIR/.groove/hooks/claude/session-capture.sh" } ] } ], "PostToolUse": [ { "matcher": "Bash", "hooks": [ { "type": "command", "command": "bash $CLAUDE_PROJECT_DIR/.groove/hooks/claude/git-activity-buffer.sh" } ] }, { "hooks": [ { "type": "command", "command": "bash $CLAUDE_PROJECT_DIR/.groove/hooks/claude/version-check.sh" } ] } ], "PreToolUse": [ { "matcher": "Write", "hooks": [ { "type": "command", "command": "bash $CLAUDE_PROJECT_DIR/.groove/hooks/claude/block-managed-paths.sh" } ] }, { "matcher": "Edit", "hooks": [ { "type": "command", "command": "bash $CLAUDE_PROJECT_DIR/.groove/hooks/claude/block-managed-paths.sh" } ] } ], "SessionStart": [ { "matcher": "startup|compact", "hooks": [ { "type": "command", "command": "bash $CLAUDE_PROJECT_DIR/.agents/skills/groove-utilities-prime/scripts/groove-utilities-prime.sh" } ] } ] } } ``` When merging: if a `hooks` key already exists, append groove entries to the relevant event arrays. Do not create duplicates — check if a groove command entry already exists before appending. ## Constraints - Never overwrite non-groove entries in `.claude/settings.json` - Never overwrite an existing script without diff + confirmation - Scripts use `python3` to parse JSON stdin — if python3 is absent, skip that hook and warn - `block-managed-paths` is aggressive: if it causes false positives the user can disable it with `--disable block-managed-paths` - After install: remind the user that hooks take effect on the next Claude Code session restart - `.groove/hooks/claude/` follows the `git.hooks` git strategy from `.groove/index.md`
