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.

How to Launch
Skills:
Skill tool → skill: "file-search"
Agents:
Task tool → subagent_type: "python-expert"
→ prompt: "Your task"
Match by Task Type
| Task | Skill First | Agent If Needed | |------|-------------|-----------------| | "How to write a CTE?" | sql-ops | sql-expert | | "Optimize this query" | — | postgres-expert | | "Find files named X" | file-search | Explore | | "Set up Python project" | python-env | python-expert | | "What HTTP status for X?" | rest-ops | — | | "React Server Components?" | react-ops | react-expert | | "Vue 3 composable pattern" | vue-ops | vue-expert | | "Configure nginx SSL" | nginx-ops | — | | "JWT vs session auth" | auth-ops | — | | "Set up Prometheus" | monitoring-ops | — | | "Debug memory leak" | debug-ops | — |
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
