What problem does it solve? Before committing to a code change, teams need to understand the current architecture, affected files, and trade-offs between approaches. This Skill performs that investigation as a dedicated exploration sub-agent and returns a structured analysis instead of ad-hoc notes. ## Core Features & Use Cases - Codebase Investigation: Reads entry points, related functionality, tests, and dependencies to map current behavior and affected files. - Approach Comparison: Compares multiple implementation options with pros, cons, and effort estimates in a consistent table format. - Artifact Persistence: Saves exploration results to Engram, OpenSpec, hybrid, or prompt-only modes depending on the configured artifact store. - Use Case: An orchestrator receives a feature request, launches this Skill to investigate the codebase, and gets back a structured report with affected files, approach options, risks, and a recommendation ready for the proposal phase. ## Quick Start Ask the orchestrator to explore how a proposed feature would affect the codebase and return a structured analysis with recommended approaches.
