Token cost

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.

Security

Grade A, and why

hidden-achievements-skill AGENTS.md 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.

How it starts

The opening of the file, as written. The whole thing — 214 lines — stays where its author put it; the contents beside it link to each section on GitHub.

PURPOSE

AGENTS.md is the policy gateway for agents in this repository. It provides strict routing, hard constraints, and command contracts. Detailed procedures live in canonical modules from ## CANONICAL DOCS.

PROJECT

  • Repository type: user project initialized with agentplane.
  • CLI rule: prefer ap for compact agent-oriented commands; fall back to agentplane; if neither is available, stop and request installation guidance (do not invent repo-local entrypoints).
  • Startup shortcut: run ## COMMANDS -> Preflight; use ap quickstart; activate ap role ORCHESTRATOR for planning and ap role <ROLE> for execution; then apply ## LOAD RULES before mutation. The guarded route is determined by workflow.mode in .agentplane/WORKFLOW.md; treat ap task brief <task-id> and ap task next-action <task-id> --explain as the route oracle: follow the emitted checkout, blocker, and next command instead of reconstructing workflow state.

SOURCES OF TRUTH

Priority order (highest first):

  1. Enforcement: CI, tests, linters, hooks, CLI validations.
  2. Policy gateway: AGENTS.md.
  3. Canonical policy modules from ## CANONICAL DOCS.
  4. CLI guidance: ap quickstart, ap role <ROLE>, .agentplane/WORKFLOW.md.
  5. Reference examples from ## REFERENCE EXAMPLES.

Conflict rule:

  • If documentation conflicts with enforcement, enforcement wins.
  • If lower-priority text conflicts with higher-priority policy, higher-priority policy wins.

SCOPE BOUNDARY

  • MUST keep all actions inside this repository unless the user explicitly approves outside-repo access.
  • MUST NOT read or modify global user files (~, /etc, keychains, ssh keys, global git config) without explicit user approval.
  • MUST treat network access as approval-gated when agents.approvals.require_network=true.

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.
