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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00931 | $0.00931 |
| Opus 5.5 | $0.00372 | $0.00372 |
| Sonnet 5.5 | $0.00186 | $0.00186 |
| Haiku 4.5 | $0.00093 | $0.00093 |
Grade A, and why
orchestkit 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 5d 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 — 74 lines — stays where its author put it; the contents beside it link to each section on GitHub.
AGENTS.md
Instructions for AI coding agents working in the OrchestKit repository. This is the
vendor-neutral companion to CLAUDE.md; where both exist, they say the same thing.
OrchestKit is a plugin for Claude Code (Anthropic's agentic CLI). It packages reusable
skills, specialist agents, and lifecycle hooks. It is source-built: you edit src/ and a
build step assembles the installable plugins/ tree. It is not a hosted service and has no
runtime backend.
The one rule that prevents most broken PRs
Edit src/ and manifests/. Never edit plugins/ by hand — it is generated.
src/ ← EDIT HERE
skills/<name>/SKILL.md # skills (YAML frontmatter + Markdown body, <500 lines)
agents/<name>.md # agents (frontmatter: name, description, model, tools, skills)
hooks/src/<category>/*.ts # TypeScript lifecycle hooks
manifests/ ← EDIT HERE (plugin definitions)
plugins/ ← GENERATED by `npm run build` — do not hand-edit
After any src/ change, run npm run build, then stage the resulting plugins/ diff
together with your src/ change in the same commit. A plugins/ diff after a build is
expected, not noise. If plugins/ comes out empty, the build was interrupted — run it again.
Build and verify
npm run build # assemble plugins/ from src/ — required after editing src/
npm test # full suite (lint + unit + security + integration + e2e)
npm test --quick # skip integration/e2e/performance
npm run test:skills # skill structure validation
npm run test:agents # agent frontmatter validation
npm run test:security # security tests — MUST pass, gates push
npm run typecheck # TypeScript check (run if hooks changed)
Before opening a PR: npm test and npm run test:security must pass, and git diff should
show real changes (not no-ops left over from a previous session).
Adding a component
- Skill — create
src/skills/<name>/SKILL.mdwith frontmatter (name,description,tags,user-invocable,complexity); body stays under 500 lines. Add it tomanifests/ork.json, thennpm run build. Seesrc/skills/CONTRIBUTING-SKILLS.md. - Agent — create
src/agents/<name>.mdwith the required frontmatter, add to the manifest, rebuild. - Hook — create
src/hooks/src/<category>/<name>.tsand register it in bothsrc/hooks/hooks.jsonand the entries mapsrc/hooks/src/entries/<event>.ts. One without the other is a silently-dead hook. Rebuild withcd src/hooks && npm run build.
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.
