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 | $0.00083 | $0.01067 |
| Opus 5 | $0.00042 | $0.00534 |
| Sonnet 5 | $0.00017 | $0.00213 |
| Haiku 4.5 | $0.00008 | $0.00107 |
Grade A, and why
ap-policies 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 yesterday.
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 — 110 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Completion Policies
When to use
Use ap-policies to gate a session (or fan-in group) at turn-end by an
objective check — a shell command's exit code or a judge sub-agent's verdict
— instead of trusting the agent's own "done" claim, and/or to auto-commit
once that gate is green, pending an explicit human ack.
MCP tool: policy_attach
Attach a gate to one sessionId, or a sessionIds array for a fan-in group
(the policy resolves once ALL sessions in the group reach turn-end). The gate
is either a shell command (basename must be allowlisted, see ap-run-command)
or a judge adapter + prompt. then decides what happens on pass: emit
(just publish policy:passed) or commit (stage + commit specific paths,
gated by requireHumanAck). onFail controls retries with a nudge prompt.
next chains another policy as a DAG.

MCP tools: policy_status / policy_list
policy_status polls state (pending | passed | failed |
awaiting_ack) plus awaitingQuestions — judge follow-ups blocking
resolution. policy_list lists active/recent policies, optionally filtered
by sessionId.

{ "tool": "policy_list", "args": { "sessionId": "sess_a1b2" } }
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.

ap-policies is a skill published in the GitHub repository agentproto/ts (5 stars, last pushed today), licensed Apache-2.0. It adds 83 tokens to every session and 1,067 once invoked, about $0.0004 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 2026-09-04.
