What it does

Tool Discovery is an agent skill from aiskillstore/marketplace. Recommend the right agents and skills for any task. Covers both heavyweight agents (Task tool) and lightweight skills (Skill tool). Triggers on: which agent, which skill, what tool should I use, help me choose, recommend agent, find the right tool.

Its SKILL.md is about 1.4k tokens, which your agent loads only when the skill is triggered. The skill folder holds 9 other files, including scripts, reference files and assets (for example `reference.md`, `references/agents-catalog.md` and `references/skills-catalog.md`).

It sits in DevOps & Cloud. It works with Docker, Laravel and PostgreSQL. The repository describes itself as: Security-audited skills for Claude, Codex & Claude Code. One-click install, quality verified. The licence is MIT.

When your agent uses it

  • What tool should I use
  • Recommend agent
  • Find the right tool

Example prompts

  • “/tool-discovery”

Requirements

  • Python 3
  • Docker
  • Pre-approved tools (allowed-tools): Read, Glob

What it can do on your machine

Read from SKILL.md and the folder at commit 4ac52da. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves these tools, so the agent can use them without asking each time:

    • Read
    • Glob

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Ships 1 file in scripts/, which the agent can run.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Tool Discovery loads about 1.4k tokens when it runs, and up to ~7.4k if it reads all its reference files. Until then it costs about 66 tokens; SKILL.md has 503 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~66
When it runs · the whole SKILL.md, loaded when a task matches
~1.4k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~7.4k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

Decision Flowchart

Is this a reference/lookup task?
├── YES → Use a SKILL (lightweight, auto-injects)
└── NO → Does it require reasoning/decisions?
         ├── YES → Use an AGENT (heavyweight, spawns subagent)
         └── MAYBE → Check catalogs below

Rule: Skills = patterns/reference. Agents = decisions/expertise.

For Cloudflare/Workers, Cypress/E2E, shell scripting, Claude Code extension work, and CMS/device domains (Payload, Craft, Asus routers), use the matching -ops skill (cloudflare-ops, cypress-ops, bash-ops, claude-code-ops, payloadcms-ops, craftcms-ops, asus-router-ops). For language/framework work (Python, TypeScript, React, Postgres, etc.), use the matching -ops skill — or dispatch general-purpose with an instruction to read that skill's SKILL.md first.

How to Launch

Skills:

Skill tool → skill: "file-search"

Agents:

Task tool → subagent_type: "firecrawl-expert"
         → prompt: "Your task"

Tips

  • Skills are cheaper - Use for lookups, patterns
  • Agents are powerful - Use for decisions, optimization
  • Don't over-recommend - Max 2-3 tools per task

Can I use Tool Discovery in Cursor, Gemini CLI or GitHub Copilot?

Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add aiskillstore/marketplace --skill tool-discovery -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/tool-discovery, .gemini/skills/tool-discovery, .github/skills/tool-discovery and .opencode/skills/tool-discovery in your project.

What does Tool Discovery need to run?

SKILL.md names no scripts, command-line tools or credentials: Tool Discovery is instructions for the agent only. Our summary lists: Python 3; Docker. Its frontmatter pre-approves these tools: Read, Glob.

Does Tool Discovery access the network?

SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.

Is Tool Discovery safe to install?

Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. The check reads SKILL.md only: the scripts in the folder are not scanned, so read them before running anything.

What licence does Tool Discovery use?

Tool Discovery is published under the MIT licence (declared in SKILL.md). It allows redistribution, so the full SKILL.md is shown on this page.

How many tokens does Tool Discovery use?

About 1.4k tokens (SKILL.md is roughly 5.6k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full. Its references folder adds about 6k tokens, read only when the agent opens those files.

What are the alternatives to Tool Discovery?

Skills that share tags, products or a category with Tool Discovery: Monstermq Broker Config (vogler75/monster-mq, 142 stars), Deploy (clacky-ai/openclacky, 1.2k stars), Code Patterns (Aedelon/claude-code-blueprint, 120 stars) and Devops (AratKruglik/claude-laravel, 155 stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
