What it does
Session Timeline is an agent skill from hoangsonww/Claude-Code-Agent-Monitor. 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.
Its SKILL.md is about 660 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files (for example `agents/openai.yaml`).
The repository describes itself as: 🚀 A real-time monitoring dashboard for Claude Code & Codex, built with SQLite3, Node.js, Express, React, Vite, TailwindCSS, & WebSockets. It tracks sessions, agent activity… The licence is MIT.
When your agent uses it
- Reconstructing what happened in a session step by step
Example prompts
- “/session-timeline”
Workflow steps
5 steps, taken from the step headings in SKILL.md.
What it can do on your machine
Read from SKILL.md and the folder at commit 1a10d68. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
npm
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use npm, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Session Timeline loads about 658 tokens when it runs. Until then it costs about 88 tokens; SKILL.md has 282 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

- description
- 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.
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,
tool_name (when present), and a one-line summary.
3. Compute durations
Pair each PreToolUse with its matching PostToolUse (same tool_name, next
occurrence) and show the tool's wall-clock duration. For TurnDuration events use
the recorded duration directly. Flag any PreToolUse with no matching PostToolUse
as unclosed.
4. Annotate notable points
Mark APIError (❌), Compaction (⚠️ context compressed), SubagentStop
(subagent finished), Notification (ℹ️), and any timeline gap > 30s between
consecutive events as an idle window.
5. Tallies
Event count by type, total tool time vs. session wall time, and the longest single tool call.
Output
A Markdown table — offset | event_type | tool_name | duration | summary — in
strict timestamp order, preceded by the header line and followed by the tallies.
Durations in ms or mm:ss.mmm; currency as USD to 4 decimal places. Never invent a
duration when a PostToolUse is missing — label it unclosed. If the dashboard is
unreachable, tell the user to start it with npm start from the repo root.
