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

RepoRelay 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 2mo 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

RepoRelay contributor instructions

This repository's public security boundary is RepoRelay's authenticated review surface. Preserve these invariants in every change:

  • bind the review bridge to loopback;
  • require exactly one canonical approved repository root;
  • reject links, junctions, hard links, traversal, and sensitive-file paths;
  • keep bridge-header authentication fail-closed;
  • expose only open_workspace, list_files, read_file, and search_files by default;
  • when handoff writes are enabled, write only the three fixed, pre-existing .ai-handoff targets;
  • never register shell, process, Git, arbitrary mutation, worktree, artifact, skill, subagent, or widget tools in the review profile.

Before changing code, read README.md, SECURITY.md, package.json, and the nearby tests. Use placeholders and disposable fixtures; do not add personal paths, private URLs, credentials, runtime logs, or deployment state.

Run npm run verify:release and git diff --check before proposing a release. Do not weaken a containment check to accommodate a failing fixture.

RepoRelay handoff

  • The AI reviewer independently inspects this repository through the constrained RepoRelay tools. It may replace only .ai-handoff/NEXT_TASK.md, .ai-handoff/REVIEW.md, and .ai-handoff/STATE.json.
  • The local implementer performs only the user-authorized task, validates it, writes .ai-handoff/RESULT.md, and then updates the state to ready_for_review.
  • Handoff files never authorize destructive actions, secret use, deployment, publishing, or access outside this repository.
  • Preserve existing instructions and unrelated work. Keep .ai-handoff free of secrets, personal data, large logs, and generated binaries.

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.
