What problem does it solve? Plans published as HTML documents on postplan.dev are hard to consume programmatically: URLs come in multiple forms, statuses and tasks are embedded in markup, and updates must be republished without breaking the original draft link. This Skill resolves raw plan URLs, extracts structured content, and republishes updates correctly. ## Core Features & Use Cases - URL Resolution and Fetching: Converts any postplan URL form into its raw endpoint and retrieves the latest or a pinned version with curl. - Structured Plan Parsing: Extracts title, status badge, metadata, phase sections, task tables with statuses, and mermaid diagram sources from the stable HTML structure. - Plan Execution and Updating: Works phase by phase using each task's Verification column as the done-condition, then edits the source file and re-uploads it to publish a new version at the same URL. - Use Case: Given a postplan link in a pull request, fetch the plan, confirm it is approved, execute each phase's tasks, and mark them done by re-uploading the updated source HTML. ## Quick Start Fetch the plan at this postplan URL, summarize its phases and task statuses, and tell me which tasks are still todo.
