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.

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 | $0.00050 | $0.03496 |
| Opus 5 | $0.00025 | $0.01748 |
| Sonnet 5 | $0.00010 | $0.00699 |
| Haiku 4.5 | $0.00005 | $0.00350 |
Grade A, and why
gut 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 9d 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.

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.

gut is a skill published in the GitHub repository rockerBOO/gut-skill (2 stars, last pushed 4mo ago), licensed GPL-3.0. It adds 50 tokens to every session and 3,496 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.

Use for dev story tasks that turn a design or bug into an implementation-ready story with owner, files, acceptance tests, and dependencies; produce verification evidence, changed or proposed files, and handoff boundaries.
cgs-regression-suite
Use for regression suite tasks that define or run regression coverage for changed systems, prior bugs, critical paths, and release blockers; produce verification evidence, changed or proposed files, and handoff boundaries.
cgs-soak-test
Use for soak test tasks that plan longer stability checks for memory, performance drift, save/load, networking, and live-ops loops; produce verification evidence, changed or proposed files, and handoff boundaries.
vibe-debugging-journal
Records resolved bugs in a persistent journal — symptom, root cause, difficulty, fix, prevention. Organized by category for future reference.
