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-patterns | 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-patterns | — |
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
