Handoff skill and bug-capture entry point: loads plan-context.md and all design artifacts, performs a critical review against the real codebase, and ensures continuous writeback to the artifacts during and after implementation. Also the entry point when a bug is reported outside of an active implementation run -- captures the FIX artefact (BACKLOG row + FIX detail file + branch) without forcing an immediate fix. Use this skill when the user mentions "implement", "code", "realize plan-context", "build feature", "Bug gefunden", "es gibt einen Fehler", "Fix erfassen", or similar, and either a plan-context.md / FEATURE spec exists OR a bug surfaced. This skill does NOT take over the coding workflow -- the Default Claude Code agent remains responsible for the actual implementation. This skill ensures the context is critically reviewed, cleanly handed off, and artifacts stay up to date.
