What problem does it solve? Sharing an implementation plan with a team usually means sending a file or link that goes stale the moment progress changes. This Skill publishes a plan-agent HTML plan to claude.ai and republishes updates to the same URL, so viewers watch steps check off live at a link they already have. ## Core Features & Use Cases - Stable URL publishing: Records the artifact URL in the plan spec's frontmatter so every later session republishes to the same page instead of minting a new link. - Title validation: Checks the plan title against the plugin's title rules before publishing, fixing the markdown spec rather than hand-editing generated HTML. - Render verification and fallback: Fetches the published URL to confirm the page rendered, and offers GitHub Pages or local gallery alternatives when publishing fails. - Use Case: A developer finishes a plan-agent plan, publishes it once, shares the URL with the team, then republishes after each status update so stakeholders always see current progress. ## Quick Start Publish my plan at docs/plans/add-auth-flow.html to claude.ai and give me the shareable URL.
