If empty, fetch <code>GET /api/sessions?limit=1</code> and report on the most recent session, stating which one.</p>\n<h2>Data Sources</h2>\n<table>\n<thead>\n<tr>\n<th>Endpoint</th>\n<th>Returns</th>\n</tr>\n</thead>\n<tbody>\n<tr>\n<td><code>GET /api/workflows/{sessionId}</code></td>\n<td>The <code>concurrency</code> dataset (overlapping agent execution lanes with start/end timing) and the <code>complexity</code> dataset (numeric score from depth, breadth, and tool diversity)</td>\n</tr>\n</tbody>\n</table>\n<h2>Report Sections</h2>\n<h3>1. Parallelism Summary</h3>\n<p>From <code>concurrency</code>: number of distinct lanes, peak parallel width (max agents running simultaneously), and total agents. Pair with the <code>complexity</code> score to judge whether the parallelism matched the work's size.\n<code>Lanes: N · Peak parallel: M · Agents: K · Complexity: S</code></p>\n<h3>2. Lane Timeline</h3>\n<p>A per-lane list of the agents that occupied each lane in order:\n<code>Lane 1: explore (0–12s) → code-review (12–48s)</code>\n<code>Lane 2: debugger (5–30s)</code>\nShow overlapping windows so simultaneity is visible.</p>\n<h3>3. Utilization</h3>\n<p>| Lane | Busy time | Idle time | Utilization % |\n|------|-----------|-----------|---------------|\nPlus an overall utilization figure (busy lane-time / total lane-time).</p>\n<h3>4. Serialization Bottlenecks</h3>\n<p>Identify sequential chains where one agent waited on the previous despite no apparent dependency — candidates to run as parallel lanes. State the chain and the wall-clock time it cost. Only flag chains the <code>concurrency</code> timing data actually shows as sequential.</p>\n<h2>Output</h2>\n<ul>\n<li>Markdown tables for utilization; a fenced list for the lane timeline.</li>\n<li>Durations in human units (e.g. <code>48s</code>, <code>2m 10s</code>); percentages to whole numbers.</li>\n<li>Use ▲/▼ when comparing utilization against an even-distribution baseline.</li>\n<li>Cite only timing returned by the API; never invent lane overlaps or durations.</li>\n<li>If the session ran a single agent (no concurrency), say so plainly rather than inventing lanes.</li>\n<li>If the dashboard is unreachable, tell the user to start it with <code>npm start</code> from the repo root.</li>\n</ul>\n","files":[{"path":"agents/openai.yaml","sizeBytes":278,"isText":true},{"path":"SKILL.md","sizeBytes":2543,"isText":true}],"reviewScore":null,"reviewSummary":null,"trust":{"provenance":"trusted-source-unreviewed","notice":"Community-authored content, reproduced verbatim and not vetted as instructions.
