What problem does it solve? Sharing agent-generated reports, diagrams, and prototypes as browsable pages requires manual hosting and link management. This Skill lets an agent publish, update, retrieve, and delete Markdown, Mermaid, HTML, and raster image resources through the Agent Whiteboard CLI, returning shareable capability URLs with controlled expiration. ## Core Features & Use Cases - Publishing workflow: Create Markdown, trusted standalone HTML, and PNG/JPEG/GIF/WebP image resources with mandatory creator context, title, and summary metadata, using structured JSON output. - Local catalog discovery: Search this laptop's metadata-only history of previously created boards with catalog list before creating duplicates or asking for known URLs. - Lifecycle management: Update content while preserving capability URLs and expiration, retrieve exact source and context, and delete resources to revoke access. - Safety and size controls: Strip secrets before publishing, respect the 500,000-byte Page Agent authoring budget, and recover correctly from catalog warnings like catalog_write_failed and creation_uncertain. - Use Case: Turn an incident report with Mermaid diagrams into a published page expiring in seven days, then return the verified absolute URL to share with teammates. ## Quick Start Use agent-whiteboard to publish this Markdown report with its diagram as a page expiring in one hour and give me the verified URL.
