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
