unwind-labs 0.3.0

Outside-in web observer for Claude Code sessions and callstack call trees

unwind

Inspect Claude Code sessions, callstack call trees, and subagents.

Run unwind serve in any project folder; a browser tab opens showing every Claude Code session that's run there, the conversation for each one, and — when the callstack plugin's /call skill is used — the call hierarchy between sessions and any spawned subagents.

Install

pip install unwind-labs

(PyPI distribution name is unwind-labs; the installed command is unwind and the Python import is unwind.)

Web UI

cd /path/to/your/claude-project
unwind serve

A browser tab opens at http://127.0.0.1:<port>/ with that project's sessions. Ctrl-C to stop.

unwind serve --help lists flags (custom port, --all project picker, --no-browser, etc.).

Keyboard shortcuts

• ← / → — switch between panes
• ↑ / ↓ — select a session or call-tree node
• Enter — open the selected node's details
• Esc — close details

CLI inspection

The same data the web UI shows is also available from the CLI. Run any of them with --help for full options; most accept --json for scripting.

• unwind project list | show | current | path — discover known projects and resolve slugs.
• unwind session list | show | tree — list sessions in a project, inspect one, or render its call/subagent tree.
• unwind messages dump | grep — dump a session's normalized messages (text/json/markdown) or grep them.
• unwind task tree | list | roots | forks — explore the unified call+subagent tree, top-level roots, and in-flight forks.

How it works

unwind reads:

• ~/.claude/projects/<slug>/*.jsonl — Claude Code's own session logs
• <project>/.claude/callstack/log/ — /call invocation reports written by the callstack plugin

…and renders them in a live-updating web UI (or prints them via the CLI). Loopback only (127.0.0.1).
