Breadth Reader
Read-only skill for exploring/reviewing/summarizing large data sources.
When to Use
Single-verb breadth tasks:
- "explore ~/dev/project/"
- "review the code in src/"
- "summarize all files in docs/"
Behavior
- Runs in forked context (isolated from main agent)
- Claude auto-optimizes parallelism internally
- Returns summary only to main agent
- No orchestration overhead
Parallel Exploration
For large data sources, spawn multiple Explore subagents (Haiku, cheap, fast):
subagent_type: Explorewith thoroughness: quick/medium/thorough
Output
Return a structured summary. Do NOT return raw file contents.
