# Agent Transit

A local subway map for one AI coding-agent session: tool families are lines and tool calls are stations.

🔒 Session logs can contain prompts, source code, command output, credentials, and other secrets. This skill is default-deny: it keeps only tool name, family, target basename, timing, status, and `agent.source`. Prompt text, assistant text, tool output, file contents, full commands, and arguments are dropped. `--show-args` is an explicit opt-in and includes only a truncated, redacted argument preview.

## Where things are

`<skill>` means the folder containing this file. Run scripts from it by absolute path, e.g. `node <skill>/src/agent-transit/scripts/find-session.mjs --source codex`. The shared engine is at `<skill>/core/`.

## Steps

1. Find the newest local session path without reading its contents: `node <skill>/src/agent-transit/scripts/find-session.mjs --source claude-code|codex|cursor`.
2. Build one page to share: `node <skill>/core/build.mjs <session.jsonl> --format claude-code --share --title "Agent: one coding session, tool by tool"`.
   Without `--out` the file is named after the title and the first failed tool call, in `./transit-out/`, e.g. `transit-out/agent-shell-git-service-alert.html`.
   `--share` scrubs at the strict level, refuses `--no-scrub`, and opens the page paused on the first failed call with a one-line verdict above the map.
   Idle stretches with nothing running (e.g. model thinking time between tool calls) longer than 3 s are shortened to 3 s so the animation isn't dead air; the header says how many were shortened and the root span keeps the wall time as `transit.wall_ms`. Pass `--max-gap-ms N` to change the cap, or `--max-gap-ms 0` for true wall-clock timing.
3. Share the HTML file: give the user its path and the verdict line the build printed, ready to paste with the file in Slack
   (desktop and iOS open it as the interactive page). Use the printed verdict as is. For example:
   > shell · git failed after 12.0 s: denied · SERVICE ALERT · 18 calls
   > `agent-shell-git-service-alert.html` opens on the denied call. Only tool names and timing are in it.
4. Optional teaser (GIF + MP4) with the bundled renderer: `node <skill>/core/render.mjs <session.jsonl> --format claude-code --name agent`.
5. Check it with the bundled verifier: `node <skill>/core/verify.mjs <session.jsonl> --format claude-code --name agent`.

Use `--format codex` or `--format cursor` for those sources.

Cursor: most Cursor installs keep chats only in `state.vscdb`, not as transcripts. Export one composer to a metadata-only JSONL (tool name, status, file basename or command word, timestamps; never message text, params or results), opened read-only:
`node <skill>/src/agent-transit/scripts/export-cursor.mjs --list` (sessions for the current workspace; `--workspace DIR` or `--all-workspaces`), then `node <skill>/src/agent-transit/scripts/export-cursor.mjs --composer <id or prefix> --out ./transit-out/agent/cursor.cursor.jsonl`, and build that with `--format cursor`.
Cursor builds since about Sep 2025 stamp each message bubble with `createdAt`, so calls start at real times; Cursor stores no tool end time, so each call ends at the next message (an upper bound). Older bubbles and `agent-transcripts` files have no timestamps: order only, with uniform synthetic durations. Keep session files local and never upload them. Synthetic fixtures are provided in `samples/`; no real home-directory logs belong in this repository.

## Rules

- Never expose or copy prompts, code, command lines, outputs, or arguments by default.
- Only use the bundled build/render/verify scripts; never hand-write a substitute renderer.
- Do not upload a session or render unless the user explicitly asks.
- Review errors, denials, slow calls, and subagent branches in the map without revealing their payloads.
```

# agent-transit

A transit map for your coding-agent sessions.

![Animated Transit map of a coding-agent session: tool families are lines, tool calls are stations, with DELAY and SERVICE ALERT markers on slow and failed calls](https://raw.githubusercontent.com/israelvicars/transit/main/docs/agent.gif)

## Example prompts

- “Make an MP4 of my last Claude Code session.”
- “Draw my latest Codex session as a transit map. Which tool calls were slow?”
- “Render my newest Cursor session as a GIF.”
- “Map this saved session log and show me where the tool errors were.”

## What it maps

Tool families become lines and tool calls become stations. Long calls receive DELAY markers, while errors or denials receive SERVICE ALERT markers.

Supported sources are Claude Code, Codex CLI, and Cursor (experimental). Session files and renders remain local.

## Install

```sh
npx skills add israelvicars/transit --skill agent-transit
```

## Privacy

Runs locally only, with no telemetry. By default it keeps only tool names, timing, status, target basenames, and the agent source.

# Synthetic agent sessions

These JSONL files are hand-built fixtures, not copied from any real `~/.claude`, `~/.codex`, or `~/.cursor` directory. Claude Code and Codex fixtures carry a synthetic marker; the Cursor fixture follows the native transcript shape and is synthetic by this README/test context. The payloads intentionally contain prompt, output, file-content, and command-argument canaries so tests prove they never reach HTML by default. Cursor timing is synthetic because the format has no timestamps or results.

// Based on the renderer in Florence's "Opus 5.5 Motion Lab" article, with fixes:
//   - viewport comes from --width/--height, else window.STAGE, else the page's first <canvas>
//     (the article hardcoded 1200x675 and silently cropped anything else)
//   - the page's requestAnimationFrame loop is frozen during capture, so a preview loop
//     cannot overwrite the frame between renderAt(t) and the screenshot (the article's version
//     produced different PNGs on repeat runs when the page had a rAF loop)
//   - old NNNN.png frames are removed first (only those files, never the folder's other contents),
//     so stale frames from a longer earlier render never end up in the MP4/GIF
//   - --frames renders only named stills (for the review loop), --scale renders at 2x
//
// usage:
//   node render.mjs <file.html> [seconds=6] [fps=24] [options]
//   node render.mjs anim.html 4 24
