0xDarkMatter Tool Discovery
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
