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 5.1 | $0.00190 | $0.00190 |
| Opus 5 | $0.00095 | $0.00095 |
| Sonnet 5 | $0.00038 | $0.00038 |
| Haiku 4.5 | $0.00019 | $0.00019 |
Grade A, and why
xiaobei-skill 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 6d 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
XiaoBei Skill Collection Routing
This repository is a collection of independently installable Codex skills. The repository root is intentionally not an installable skill and must not contain SKILL.md.
When a user asks to install xiaobei-skill, this repository, or its root URL without naming a child skill:
- Read
skill-catalog.json. - Show every listed skill's
display_name, description, and path. - Ask the user which one they want.
- After the user chooses, install only that exact child path with
$skill-installer. - Do not infer a default and do not install all skills unless the user explicitly asks for all of them.
When a user explicitly names one child skill, install that child directly. When the user explicitly asks for all skills, install every path listed in the catalog.
Do not treat repository documentation, examples, gallery assets, or the repository root as skills.
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.

xiaobei-skill AGENTS.md is an instructions file published in the GitHub repository xiao24bei/xiaobei-skill (280 stars, last pushed 9d ago), licensed Apache-2.0. It adds 190 tokens to every session, about $0.0010 per session on Opus 5. A static security scan graded it A with 0 findings.
