Session Report
Generates a single self-contained HTML file that reconstructs an agent session from its transcript and shows what is in the model's context window and how every token is spent — a forensic debugger for context bloat and the "dumb zone" (context-rot past ~40% of the window).
This is a user-invoked command (/session-report); it is not auto-invoked by the model.
The session id is passed as the $session_id argument.
What the report shows
- Verdict header + gauge: peak context vs window, health (Healthy / Degrading / Rotting), one-click jump chips to every issue.
- Context budget at peak: a stacked bar + table partitioning the peak context into system+tools, listings (skills/agents/tools), CLAUDE.md/memory, opened files, user prompts, tool results, assistant text, thinking, and an honest "unattributed (tool schemas/overhead)".
- Context-growth timeline: inline-SVG stacked area of real context size per turn, with the dumb-zone band, the 200K-model ghost line, compaction cliffs, peak marker, and the first dumb-zone crossing.
- Loaded artifacts: CLAUDE.md/AGENTS.md/memory sizes (read from disk), skill/agent/tool listings, opened files — sortable, with "trim me" callouts.
- Biggest items and a full collapsible history of every event (tool calls, results, attachments) with search/filter and the dumb-zone divider inline.
