act-sdk-js: Skill for Claude Code

.agents/skills/find-skills/SKILL.md

find-skills is a skill for Claude Code, Codex from act-sdk/act-sdk-js. It costs 67 tokens per session (1,295 once invoked), scanned A, a copy of find-skills, MIT.

A guide for finding and installing skills that add specialized workflows to an AI coding agent. It uses the Skills CLI, a package manager for browsing, installing, and updating these skills.

In plain words
What is it for?
Use it when you need help discovering a skill for tasks such as design, testing, deployment, or another specialized area.
Why use it?
It removes the need to know which skill exists or where to find it. It helps turn a general request into a search for a suitable add-on.

Skill for Claude CodeCodex

Written for no agent in particular: nothing here depends on one. Also seen: installed under .agents/ (shared by several agents).

This is act-sdk/act-sdk-js's own configuration. It tells Claude Code and Codex how to work on act-sdk-js itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything act-sdk-js configures →

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

find-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 9d 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.

Find Skills

This skill helps you discover and install skills from the open agent skills ecosystem.

When to Use This Skill

Use this skill when the user:

  • Asks "how do I do X" where X might be a common task with an existing skill
  • Says "find a skill for X" or "is there a skill for X"
  • Asks "can you do X" where X is a specialized capability
  • Expresses interest in extending agent capabilities
  • Wants to search for tools, templates, or workflows
  • Mentions they wish they had help with a specific domain (design, testing, deployment, etc.)

What is the Skills CLI?

The Skills CLI (npx skills) is the package manager for the open agent skills ecosystem. Skills are modular packages that extend agent capabilities with specialized knowledge, workflows, and tools.

Key commands:

  • npx skills find [query] - Search for skills interactively or by keyword
  • npx skills add <package> - Install a skill from GitHub or other sources
  • npx skills check - Check for skill updates
  • npx skills update - Update all installed skills

Browse skills at: https://skills.sh/

How to Help Users Find Skills

Step 1: Understand What They Need

When a user asks for help with something, identify:

  1. The domain (e.g., React, testing, design, deployment)
  2. The specific task (e.g., writing tests, creating animations, reviewing PRs)
  3. Whether this is a common enough task that a skill likely exists

Step 2: Check the Leaderboard First

Before running a CLI search, check the skills.sh leaderboard to see if a well-known skill already exists for the domain. The leaderboard ranks skills by total installs, surfacing the most popular and battle-tested options.

For example, top skills for web development include:

  • vercel-labs/agent-skills — React, Next.js, web design (100K+ installs each)
  • anthropics/skills — Frontend design, document processing (100K+ installs)

Step 3: Search for Skills

If the leaderboard doesn't cover the user's need, run the find command:

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.
