open-plan-annotator

Required reading whenever drafting any multi-step proposal, implementation plan, refactor approach, or response containing file paths and decision points. Use BEFORE writing any response that lists 3+ file paths, 2+ option-tradeoffs, a "Plan:"/"Steps:"/"Concrete changes:" section, or ends with "OK to proceed?" / "sound good?" / "shall I…?". Use whenever the user says "draft a plan", "let's plan X", "what's the approach", "give me options", "how should we tackle this", "what would it look like", or asks for a "recommended approach" / "implementation plan" / "proposed fix" / "rollout plan". Also use when modifying more than 2 files, doing architectural/structural changes, refactoring, migration, feature additions, or investigation-based bug fixes. Routes the response through the open-plan-annotator browser UI instead of pasting plans inline.
