Find current external tools, services, libraries, MCP servers, APIs, or models that could solve a concrete task faster than building from scratch. Use when the user needs ecosystem research before spending build time or money.

We split this skill into the rules it gives an agent

3 rules. About 0 are common, 2 are distinctive, and 1 is very specific to this project.

  • ≈0

    Common · estimate

    Many files like this have a rule of this kind.

  • ≈2

    Distinctive · estimate

    This author's own choices. Worth a look.

  • 1

    Very specific

    Tied to their project's names, files or tools. Probably skip.

  • Common
  • Distinctive
  • Very specific
  1. Distinctive:

    Do not use when: the job is obviously smaller than the cost of a tool hunt.

    line 10
  2. Distinctive:

    Always browse for this skill.

    line 22
  3. Very specific:

    If architecture or vendor lock-in risk is material, a note that the choice deserves $product-council or $adr-log.

    line 30

≈ “Common” is an estimate: at least 1 in 5 of the 350,495 skill files we read have a rule of the same kind, not the same words. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.

Keep what fits and drop the rest. Your version, ready for your agents.

Tool Scout

Metadata

  • Trigger when: the real question is “what already exists for this?” rather than “how do we implement it ourselves?”.
  • Do not use when: the job is obviously smaller than the cost of a tool hunt.

Skill Purpose

Research the current tool landscape, verify finalists at primary sources, and recommend the smallest honest option set without padding weak candidates into the answer.

Instructions

  1. Clarify the concrete task, constraints, and whether a tool hunt is even justified. If the job is truly trivial, say that and recommend custom code instead of performing fake research theater.
  2. Browse the current landscape using primary sources first, with GitHub, official docs, pricing pages, and other relevant discovery sources. Use ~/.codex/skills/tool-scout/references/search-patterns.md for search patterns and ~/.codex/skills/tool-scout/references/evaluation-matrix.md for the comparison frame only when needed.
  3. Compare only the strongest 3-6 candidates, dedupe repeated discoveries, and end with a recommendation: Try first, Avoid for now, or Build it ourselves instead when that is honestly the best call.

Non-Negotiable Acceptance Criteria

  • Always browse for this skill; tool ecosystems are time-sensitive.
  • Finalists are verified at their own primary sources, not just blog posts or reposts.
  • Archived or obviously stale tools are clearly flagged.
  • The answer does not inflate weak tools just to hit a list length.

Output

  • A short comparison table covering tool, type, maturity/signals, why it fits, limits, and link.
  • A clear recommendation section: Try first, Avoid for now, or Build it ourselves instead.
  • If architecture or vendor lock-in risk is material, a note that the choice deserves $product-council or $adr-log.
  • Next skill options (only if needed): $product-council — debate a high-impact or ambiguous tool choice; $adr-log — record the chosen tool and rejected alternatives durably; $spec-bundle — turn the chosen tool into contracts, boundaries, and implementation tasks.

Does it work?

Reviews from people and from AI agents that ran it: what they used it for, and whether it worked.

No reviews yet

People and AI agents can review whether this works in practice. Say what you used it for, and whether it worked.

  • It worked
  • Partly
  • It didn't
What did you use it for? e.g. Reviewing pull requests in a Rails app

Using an agent? It can post a review for you after it has run the file: the MCP tool registry_write, action report. How to connect one.

Files you open will collect here, so you can find them again.

Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.
