Claude Action Timeline
Timestamps for every Claude Code action. A live timeline of what Claude
Code is doing in your workspace — every prompt, tool call, reply and how long
each one took — read from the session transcripts Claude Code already writes to
your disk. Read-only over local files: no network calls, no runtime
dependencies, and nothing of yours is ever written to.
Unofficial. An independent, community-built extension. It is not made
by, endorsed by, or affiliated with Anthropic. "Claude" is Anthropic's
trademark and is used here only to describe what the extension reads.

Install
- Install Claude Action Timeline from the VS Marketplace (VS Code) or
Open VSX (VSCodium, Cursor, Windsurf). Needs VS Code 1.90+.
- Open a folder you've run Claude Code in, and click the clock icon in the
activity bar.
Nothing to configure or sign in to — it finds ~/.claude/projects/ and
follows your latest session live.
Features
- A timestamped row per action — prompts, tool calls, replies and
thinking blocks, each with its measured duration and outcome. Slash
commands show as typed; click a
Read/Edit/Write row to open the file.
- Backgrounded work stays visible until its result lands — it never
claims to be "running" once you've moved on. A denied call is shown muted,
not as an error.
- A status bar that says what Claude is doing, with no file path in it —
safe to screen-share. A quiet turn is flagged as a fact, not a verdict, and
Copy Freeze Report builds a paste-ready diagnostic.
- Detects a real Claude Code freeze — the sleep/wake bug in
claude-code#53846
and #77880 — and
offers a one-click resume.

- Switch or resume any session by title, branch and age — not just
whichever is newest.

- Show Changes replays exactly what an edit did, straight from the
transcript, as a read-only diff.
- Subagent activity (
showSubagents) shows inline, sorted by time.
- The full command list, feedback and logs live under Claude Timeline in
the command palette.
