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: Explore with thoroughness: quick/medium/thorough

Output

Return a structured summary. Do NOT return raw file contents.
