Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.03790 | $0.03790 |
| Opus 5 | $0.01895 | $0.01895 |
| Sonnet 5 | $0.00758 | $0.00758 |
| Haiku 4.5 | $0.00379 | $0.00379 |
Grade A, and why
ai CLAUDE.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 2d 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 Overview
@formio/ai — the Form.io agentic coding toolset. A pnpm + Turborepo monorepo shipping three things: the @formio/mcp Model Context Protocol server (packages/mcp-server/, exposing form_* / role_* / action_* / project_* tools), the @formio/ai agent plugin (plugin/, bundling the server + skill library behind three manifests — .claude-plugin/plugin.json for Claude Code, .cursor-plugin/plugin.json for Cursor, and plugin.json + mcp.json for the vendor-neutral Agent Plugins layout), and a @formio/skill-tests package (packages/skill-tests/) that runs the formio-sdk skill's doc examples against the real @formio/js. The skill library lives at plugin/skills/ (eleven activatable skills). It is also installable skills-only with npx skills add formio/ai, in which case plugin/skills/formio-mcp-setup/ connects the MCP server on first use — every other skill carries a preflight that hands off to it when the Form.io tools are missing, and is forbidden from working around the gap with raw HTTP.

Skills Library
The repository ships a Claude skills library at plugin/skills/ covering every endpoint in the Form.io API Postman collection. The Form.io API surface is consolidated into a single activatable skill at plugin/skills/formio-api/SKILL.md; per-capability-group endpoint details live as reference documents under plugin/skills/formio-api/references/ (one .md file per group, no frontmatter). Claude activates the router skill whenever the user asks about a Form.io REST endpoint and navigates into the relevant reference by scope (platform, project, runtime, pdf).
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.

ai CLAUDE.md is an instructions file published in the GitHub repository formio/ai (6 stars, last pushed 2d ago), licensed MIT. It adds 3,790 tokens to every session, about $0.0190 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
