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 | $0.00033 | $0.00305 |
| Opus 5 | $0.00016 | $0.00152 |
| Sonnet 5 | $0.00007 | $0.00061 |
| Haiku 4.5 | $0.00003 | $0.00030 |
Grade A, and why
universal-ai-skills 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 12d 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
Universal AI Skills Router
- Canonical source:
%USERPROFILE%\universal-ai-skills-library. - Binary:
%USERPROFILE%\go\bin\skill-router.exeon PATH asskill-router. - For substantive user prompts, run
skill-router preflight --hook-event UserPromptSubmit --json "<latest user prompt>"from prompt-submit hooks, orskill-router preflight --json "<latest user prompt>"from the host AI precheck. - Run automatic routing only for real user prompts. Do not route from tool output, assistant messages, startup, stop, compaction, status checks, or background jobs.
- If
decisionisroute, sanity-check that the selected skill clearly matches the user's core task, object, and action. Then load only that skill withskill-router skill <name>. - If
decisionisambiguous,host_ai_review.requiredis true, or the match only hits generic words such as "issue", "install", "setup", "local", "AI", or "skill", continue without loading a skill unless one candidate is clearly correct. - Search unknown skills with
skill-router skill search <query> --limit 10. - Keep this wrapper compact. Do not copy or paste the full skills corpus into plugin context.
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.

universal-ai-skills is a skill published in the GitHub repository onfire7777/universal-ai-skills-library (16 stars, last pushed yesterday), licensed MIT.
