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

yq-doc-maintenance 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 8d 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.

Documentation Governance

Maintain a coherent documentation system whose claims have clear owners and can be checked against the project. Start with ownership and structure; edit prose only after the source of truth is known. This skill covers Markdown, READMEs, tutorials, runbooks, reference docs, decision records, postmortems, JSDoc, and code comments. Use yq-technical-writing for sentence-level coverage and clarity, and yq-remove-reasoning-leaks for authoring-session residue. If the audit exposes implementation, test, or gate complexity rather than a documentation-ownership problem, invoke $yq-simplify-code for that candidate instead of hiding a behavior change inside documentation cleanup.

This is guidance, not a universal folder layout. Discover and preserve the repository's own documentation contract.

Establish the documentation contract

  1. Confirm the requested scope and whether the task is an audit, a proposal, or an authorized edit. Use the narrowest defensible scope from the request and current diff; do not silently expand a focused task into a repository-wide rewrite.
  2. Snapshot the audit identity: repository, checkout or worktree, branch, revision, dirty state, and applicable instructions. Recheck it before reporting. If the worktree changes during the audit, stop combining observations, anchor completed findings to the captured revision, and list later changes as uninspected.
  3. Read applicable AGENTS.md, CLAUDE.md, CONTEXT.md, root and package READMEs, documentation indexes, architecture/decision records, contribution guides, and CI or package scripts that validate docs.
  4. Identify excluded or derivative areas: third-party sources, generated catalogs, build output, recorded fixtures, snapshots, vendored documentation, and frozen archives. Edit an owner before regenerating a derivative artifact.
  5. Record how this repository expresses intended behavior, observed behavior, rationale, and process. Code or runtime evidence can establish what happens; it does not automatically overrule a current product specification. When those disagree, label the mismatch instead of silently choosing one.

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.
