Tool Discovery
SkillProductivityRecommend 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.
Available today. Use it from your connected AI after setup.

What this skill tells your AI
The instructions your AI receives, as published by 0xdarkmatter/claude-mods in skills/tool-discovery/SKILL.md and read by ahel’s review.
Recommend the right agents and skills for any task.
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"
Match by Task Type
| Task | Skill First | Agent If Needed |
|---|---|---|
| "How to write a CTE?" | sql-ops | — |
| "Optimize this query" | postgres-ops | — |
| "Find files named X" | file-search | Explore |
| "Set up Python project" | python-env | — |
| "What HTTP status for X?" | rest-ops | — |
| "React Server Components?" | react-ops | — |
| "Vue 3 composable pattern" | vue-ops | — |
| "Configure nginx SSL" | nginx-ops | — |
| "JWT vs session auth" | auth-ops | — |
| "Set up Prometheus" | monitoring-ops | — |
| "Debug memory leak" | debug-ops | — |
| "Scrape a blocked site" | jina-ops | firecrawl-expert |
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
