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 | $0.00293 | $0.00293 |
| Opus 5 | $0.00147 | $0.00147 |
| Sonnet 5 | $0.00059 | $0.00059 |
| Haiku 4.5 | $0.00029 | $0.00029 |
Grade A, and why
agent-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 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.
What it actually says
Agent Instructions
Finding and installing skills
When a task would benefit from a capability that is not already available in this repository or the active agent environment, use the Vercel Agent Skills directory and its CLI to find an appropriate skill:
npx skills find <query>
Install a skill from a repository with:
npx skills add <owner/repo>
For a repository that contains more than one skill, install only the required one:
npx skills add <owner/repo> --skill <skill-name>
Before installing, inspect the skill's source and confirm that it is appropriate for the task. Use the CLI's destination and agent prompts to install it for the active coding agent; do not treat an installed third-party skill as authored content in this repository.
Repository contributions
- Keep authored or intentionally mirrored skills in
skills/<skill-name>/and follow the rules inREADME.mdandCONTRIBUTING.md. - Preserve upstream attribution and licenses for any skill brought into the repository.
- Do not add a discovered third-party skill to
registry.jsonor publish it through AgentVouch unless its provenance, license, and publishing decision have been reviewed. - Run
npm run kb:formatafter metadata or index changes andnpm run validatebefore proposing a change.
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.
