Render an ordered timeline of one Claude Code session's events (every event type) with per-event durations and tool names, reconstructed from Agent Monitor data. Pairs PreToolUse with PostToolUse to compute tool durations and surfaces gaps, errors, and compaction points. Use when reconstructing what happened in a session step by step.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Session Timeline Reconstruct the chronological event timeline of a single Claude Code session. ## Input The user provides: **$ARGUMENTS** - A **session ID** to time-line, or - "latest" / "last" for the most recent session. ## Data Sources | Endpoint | Returns | |----------|---------| | `GET /api/sessions/:id` | session header: status, model, cwd, started_at, ended_at, cost, metadata (thinking_blocks, turn_count, total_turn_duration_ms) — and nested events | | `GET /api/events?session_id=X` | the full event stream: event_type (PreToolUse, PostToolUse, Stop, SubagentStop, SessionStart, SessionEnd, Notification, Compaction, APIError, TurnDuration), tool_name, summary, data, timestamp | ## Report Sections ### 1. Resolve & header If "latest", `GET /api/sessions?limit=1` to get the id, then `GET /api/sessions/:id`. Print a one-line header: id, status, model, cwd basename, started_at → ended_at, turn_count, total_turn_duration_ms, cost. ### 2. Build the ordered timeline `GET /api/events?session_id=X`. Sort strictly by `timestamp`. For each event emit a row with: relative offset from `started_at` (e.g. `+00:03.412`), event_type, …

How to install
mdr add hoangsonww/claude-code-agent-monitor/session-timeline@sha256:b46c7ab4990abda9The line at the top of this page pins the label git:20260804.9eab0d7, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
