# Session Scan (Tier 1)
Compute deterministic metrics for sessions discovered via ccrider MCP.
## STOP — Read Before Executing
**NEVER call `mcp__ccrider__get_session_messages` in main context.**
Each response is 5-50KB of JSON. Fetching N sessions directly = context crash.
**You MUST delegate all scoring to subagents.** The main context only does:
discovery, deduplication, subagent spawning, and result collection.
## Requirements
Requires **ccrider MCP**. If not available:
> ccrider MCP is required. See: <https://github.com/neilberkman/ccrider>
