Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

What it costs to keep this loaded
Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00044 | $0.02486 |
| Opus 5.5 | $0.00018 | $0.00994 |
| Sonnet 5.5 | $0.00009 | $0.00497 |
| Haiku 4.5 | $0.00004 | $0.00249 |
Grade A, and why
groove-admin-claude-hooks scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 242 lines — stays where its author put it; the contents beside it link to each section on GitHub.
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.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
