What is skills AGENTS.md?

Project instructions for the WorkOS skills package, covering integrations such as sign-in, single sign-on, directory synchronization, roles, and fine-grained access control.

Use them when developing or reviewing WorkOS integration skills, running tests and checks, or evaluating specific cases.

They give contributors the commands and conventions needed to test, format, lint, and evaluate changes in that package.

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.

Model	Per session	Once invoked
Fable 5.1	$0.01740	$0.01740
Opus 5.5	$0.00696	$0.00696
Sonnet 5.5	$0.00348	$0.00348
Haiku 4.5	$0.00174	$0.00174

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 10d 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.

Project Structure

.agents/plugins/marketplace.json — Codex marketplace catalog (source: ./plugins/workos)
.cursor-plugin/marketplace.json — Cursor marketplace catalog (mirrors Claude catalog)
plugins/workos/ — installable plugin (only this gets cached)
- .codex-plugin/plugin.json — Codex plugin manifest
- .cursor-plugin/plugin.json — Cursor plugin manifest (mirrors Claude manifest; versions synced by release-please)
- skills/ — skill directories, each with SKILL.md
  - Hand-crafted AuthKit skills: workos-authkit-base, workos-authkit-nextjs, workos-authkit-react, workos-authkit-react-router, workos-authkit-tanstack-start, workos-authkit-vanilla-js, workos-widgets
  - Router: workos/SKILL.md — routes user requests to the right topic file or AuthKit skill
  - Topic files: workos/references/*.md — lean files with doc URLs + gotchas + optional endpoint tables
well-known/setup/SKILL.md — standalone setup skill that workos.com serves at /SKILL.md. Not part of the plugin; it condenses the router's "Start here" section, so update both together
scripts/ — eval framework (not cached with plugin)
- tests/ — *.spec.ts files using vitest
- build-well-known.ts — builds the /.well-known/agent-skills/ archives and index.json that .github/workflows/well-known.yml attaches to each release; workos.com serves the latest release's index, which points at that release's archives

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.
