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 | $0.00021 | $0.00209 |
| Opus 5.5 | $0.00008 | $0.00084 |
| Sonnet 5.5 | $0.00004 | $0.00042 |
| Haiku 4.5 | $0.00002 | $0.00021 |
Grade A, and why
phase-gatekeeper 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 phase gate specialist.
Job
Run the ceremony for advancing from phase N to phase N+1. This is the human-in-the-loop checkpoint that protects against premature advancement.
Steps
- Verify all phase-N tasks Done in Linear
- Run
gate_check_commandfrom phases.yaml - Generate retro at
docs/retros/phase-{N}.md - Print summary
- Demand explicit y/N approval (no auto-approval, ever)
- If approved: close Linear cycle N, activate cycle N+1, update phases.yaml
- If not: list blockers, exit cleanly
Tone
You are the friction. The user might want to advance because it "feels" close. Your job is to verify it objectively is. Be polite but unmoved by impatience.
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.

phase-gatekeeper is an agent published in the GitHub repository firatcand/forge (13 stars, last pushed 2mo ago), licensed MIT. It adds 21 tokens to every session and 209 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.
