What problem does it solve? Planning a feature or refactor without knowing the real codebase structure leads to hallucinated file paths, missed dependencies, and broken implementations. This Skill grounds implementation plans in the actual code graph, validating every reference before you write code. ## Core Features & Use Cases - Graph-grounded planning: Generates ordered navigation waypoints and a YAML implementation spec via ch_ocxp_plan, combining route and spec generation in one call. - Reference validation: Runs ch_ocxp_standards_check to catch hallucinated file paths and function names, then corrects them with ch_ocxp_search. - Compliance and impact analysis: Audits the plan against codebase rules with ch_ocxp_audit and maps the blast radius of changes using ch_ocxp_references, topology, and community detection. - Use Case: Ask to plan adding rate limiting to an API, and receive a structured plan listing files to modify in dependency order, new files to create, affected downstream consumers, naming constraints, and risks. ## Quick Start Ask the assistant to plan a refactor of the authentication module and show which files and downstream consumers are affected.
