Reduces context exhaustion during /gsd:map-codebase by having agents
write documents directly instead of returning findings to orchestrator.
- Create gsd-codebase-mapper agent with embedded templates
- Agent understands downstream consumers (plan-phase, execute-plan)
- Parameterized by focus: tech, arch, quality, concerns
- Each focus writes specific documents directly to .planning/codebase/
- Orchestrator receives only confirmation + line counts
Context savings: ~40 lines returned vs potentially thousands of lines
of exploration findings previously transferred back to orchestrator.
