What problem does it solve? Long investigations, code reviews, and multi-source research lose structure and traceability when pasted as markdown in chat. This Skill turns an analytical result into a single self-contained index.html with a mandatory executive summary, cited findings, drilldown evidence, and a run-metadata appendix. ## Core Features & Use Cases - Structured report contract: Every report includes an executive summary (question, context, findings, confidence), optional recommendations / open questions / out-of-scope sections, and an appendix recording model, prompt, tools, and sources. - Rich block catalog: Typed blocks for tables (sortable), code with syntax highlighting, diffs, key-value lists, collapsible drilldowns, figures, and Vega-Lite charts, all inlined into one portable HTML file. - Deep provenance: Findings link via stable src- ids to URLs, file:line references, PRs, commits, and screenshots listed in the appendix. - Use Case: After investigating why p99 write latency spiked in a service, ask for an HTML report; the Skill assembles findings, traces, diffs, and benchmark tables into ~/reports/<slug>-<ts>/index.html and optionally opens it in your browser. ## Quick Start Investigate the recent latency spike in the order service and write the results up as an HTML report with cited sources and a confidence rating.
