Produce a comprehensive, bounded post-run report after a long agent session — many hours, many tickets, or thousands of lines — and write it as a self-contained HTML artifact into `.recaps/` in the repo. Answers the question a commit list cannot: what can I do now that I could not before, what needs me, and what should I not trust. Use when the user says "recap", "what did you just do", "session report", "post-task report", "summarize this session", "what changed", "I can't follow the scrollback", or at the end of any run too long to reconstruct by reading the tail of the console. Prefer running it from a FRESH session against the finished one. Do NOT use for a periodic project update to an audience (activity-report), a customer changelog, or a PR description (pr-creator).

A Cursor Canvas is a live React app that the user can open beside the chat. You MUST use a canvas when the agent produces a standalone analytical artifact — quantitative analyses, billing investigations, security audits, architecture reviews, data-heavy content, timelines, charts, tables, interactive explorations, repeatable tools, or any response that benefits from visual layout. Especially prefer a canvas when presenting results from MCP tools (Datadog, Databricks, Linear, Sentry, Slack, etc.) where the data is the deliverable — render it in a rich canvas rather than dumping it into a markdown table or code block. If you catch yourself about to write a markdown table, stop and use a canvas instead. You MUST also read this skill whenever you create, edit, or debug any .canvas.tsx file.
