Use this skill when the task involves understanding the real control plane of the repository, identifying authoritative modules, mapping startup order, call chains, and hidden side effects before any refactor or migration.
Use this skill when migrating the terminal app, REPL loop, prompt submission flow, command dispatch, and interactive runtime behavior to Python.
Use this skill when touching configuration, settings, caches, plugin-injected settings, or precedence rules during migration.
Use this skill when planning the staged transition from the TypeScript implementation to the Python implementation with minimal behavior drift.
Use this skill when porting MCP config, client lifecycle, memoized connections, tool/resource discovery, plugin loading, or extension behavior.
Use this skill when building verification harnesses that prove the Python port matches the TypeScript implementation for key user flows.
Use this skill when working on permission policy, tool allow/deny/ask behavior, sandbox enforcement, or execution safety during the Python migration.
Use this skill when preserving behavior matters more than rewriting style, especially during TypeScript-to-Python migration of orchestration-heavy systems.
