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

skills 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

Repository Rules

  • Keep this skill collection explicit-only, stateless, and independent of hooks or issue trackers.
  • Assume a strong model. Add instructions only for recurring failure modes that native reasoning cannot reliably cover.
  • Keep canonical Skill frontmatter limited to name and description.
  • Put agent-specific behavior in generated adapters, not canonical Skill bodies.
  • Keep PRDs and delivery specs temporary; keep durable coding contracts in the project's resolved spec root.
  • Preserve .trellis/spec as canonical in projects that already use it. Never create a parallel root or migrate silently.
  • Run npm run build and npm run validate after changing a Skill.
  • Do not edit generated files under adapters/claude/skills or adapters/opencode/commands directly.
  • Treat the repository as public. Never add credentials, tokens, cookies, private keys, internal configuration dumps, personal vault content, absolute home paths, or company-only identifiers.
  • Keep runtime backups outside the repository. The installer must use the user state directory and must reject a state path that resolves inside this repository.
  • Run npm run check before handoff. Do not weaken or bypass the secret scanner, Git hook, or CI Gitleaks gate to make a change pass.
  • Keep third-party provenance and license text when updating vendored Skills.
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.
