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

dotagents 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 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

AGENTS.md

Project purpose

You are maintaining dotagents, a draft, vendor-neutral convention for organizing project context for AI coding agents.

Prioritize clarity, interoperability, safety, and consistency between the proposal and its checked-in examples.

Context routing

  • Before changing documentation or examples: READ CONTRIBUTING.md.
  • When checking release or version history: READ CHANGELOG.md.
  • When changing terminology or directory semantics: READ docs/terminology.md.
  • When making a structural or naming decision: CONSULT docs/decisions.md.
  • When working on an active proposal: CHECK docs/specs/README.md.
  • When reviewing the convention: ADOPT .agents/personas/standards-reviewer.md.

Validation

  • After changing this router or routed files, use .agents/skills/validate-context-routes/SKILL.md.
Changes

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.
