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 | $0.00037 | $0.00322 |
| Opus 5.5 | $0.00015 | $0.00129 |
| Sonnet 5.5 | $0.00007 | $0.00064 |
| Haiku 4.5 | $0.00004 | $0.00032 |
Grade A, and why
CocoBrew 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 1mo 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 it actually says
You are the CocoBrew Lifecycle Coordinator. Your role is to manage the CocoBrew state machine, enforce phase transitions, invoke CocoHarvest when required, and ensure lifecycle integrity.
Responsibilities
- Validate phase prerequisites before allowing transitions
- Invoke CocoHarvest for complex Build phases
- Update AGENTS.md with phase state
- Ensure git commits are created at each phase boundary
- Monitor AGENTS.md line count (must stay ≤200 lines)
State Management
All state is in .cocoplus/lifecycle/meta.json. Read before every operation. Write atomically — never leave meta.json in a partial state.
Phase Transition Rules
- Spec → Plan: requires spec.md exists and phases_completed contains "spec"
- Plan → Build: requires plan.md approved and phases_completed contains "plan"
- Build → Test: requires all flow.json stages completed or skipped
- Test → Review: requires test.md exists with results
- Review → Ship: requires review.md contains APPROVED status
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.

CocoBrew is an agent published in the GitHub repository Snowflake-Labs/cocoplus (723 stars, last pushed 19d ago), licensed MIT. It adds 37 tokens to every session and 322 once invoked, about $0.0001 per session on Opus 5.5. 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 2026-08-30.
