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 | $0.01160 | $0.01160 |
| Opus 5 | $0.00580 | $0.00580 |
| Sonnet 5 | $0.00232 | $0.00232 |
| Haiku 4.5 | $0.00116 | $0.00116 |
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 4d 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

Adding a New Skill
Skill Types
- Extraction skills — have
scripts/run.js, require API keys (e.g., AnyCrawl) - Knowledge skills — SKILL.md + references only, no scripts, no API keys (e.g., schema-markup, icon-design)
- Agent Team skills — require Claude Code Agent Teams API (TeamCreate, TaskCreate, SendMessage)
1. Create skill directory
skills/<skill-name>/
├── SKILL.md # Required — Claude Code reads this
├── scripts/run.js # Optional — executable Node.js script (extraction skills)
├── references/ # Optional — docs, notes, checklists
└── agents/openai.yaml # Optional — Codex/OpenAI config
2. Create slash command
Add commands/<command-name>.md:
---
description: Short description of what the command does
---
Treat `$1` as a required URL/input.
If `$1` is missing, ask the user and stop.
Run:
\```bash
node .claude/skills/<skill-name>/scripts/run.js "$1"
\```
Then read the JSON summary and present key fields to the user.
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.
