What problem does it solve? When working on a large repository, broad grep-style searches waste time and miss structural relationships. This Skill retrieves structural codebase knowledge—symbols, call graphs, ownership, dependencies, and impact maps—through the codebase-memory MCP index so each workflow stage gets precise, justified code context. ## Core Features & Use Cases - Structural Code Queries: Looks up symbols, callers/callees, files, and modules through the codebase-memory MCP index instead of broad repository searches. - Impact Mapping: Maps impacted packages and boundaries, escalating cross-package impacts to the Technical Architect role. - Graceful Degradation: Falls back to targeted file reads when the MCP index is unavailable and records the degraded mode in the output. - Use Case: During a multi-stage spec-driven workflow, a stage needs to know which modules are affected by changing a shared utility function. This Skill queries the index, maps the impacted packages, and returns a typed context.codebase evidence package with confidence and handoff fields. ## Quick Start Ask the agent to gather structural codebase context for the current stage, including impacted symbols, callers, and package boundaries, using the codebase-memory index.
