Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

agent-skills 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 7d 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.

Origin

This is a copy

100% identical to agent-skills AGENTS.md — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

How it starts

The opening of the file, as written. The whole thing — 97 lines — stays where its author put it; the contents beside it link to each section on GitHub.

AGENTS.md

This file provides guidance to AI coding agents (Claude Code, Cursor, Copilot, etc.) when authoring skills in this repository.

Repository overview

A collection of skills for AI coding agents, maintained by Zapier teams. Skills are packaged instructions and scripts that extend an agent's capabilities. Skills are indexed by skills.sh and installable via npx skills add.

Creating a new skill

Directory structure

Skills are grouped into a subfolder per team or project under skills/:

skills/
  <team-or-project>/        # kebab-case team/project namespace, e.g. workflows
    <skill-name>/           # kebab-case skill directory
      SKILL.md              # Required: skill definition
      scripts/              # Optional: executable scripts
        <script-name>.sh    # Bash scripts
        <script-name>.mjs   # Node scripts
      references/           # Optional: supporting docs loaded on demand
      lib/                  # Optional: shared code for scripts

Naming conventions

  • Team/project folder: kebab-case (e.g. workflows).
  • Skill directory: kebab-case (e.g. install, build).
  • SKILL.md: always uppercase, always this exact filename.
  • name: field: prefix with <team>- (e.g. workflows-install). The folder can stay short, but the name: is what the agent sees once a skill is installed alongside skills from every other source — keep it unambiguous and collision-proof. Generic names like install or build must be namespaced.
  • Scripts: kebab-case.sh or kebab-case.mjs.

SKILL.md format

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.
