# Sessions sidebar

**Status:** Implemented · **Code:** `Scripts/sidebar.js`, `Scripts/sessions-store.js`

Two sections: **Claude** (account, model, permission mode) and **Sessions** (the
project's conversations, newest first, each expanding into its actions).

```

## Where sessions come from

Claude Code stores one JSONL transcript per session:

```
~/.claude/projects/<slug>/<session-id>.jsonl
```

The slug is the project path with `/` and `.` flattened to `-`
(`/Users/me/git.example.ca/thing` → `-Users-me-git-example-ca-thing`). Files are
sorted by mtime; `firstPrompt()` reads up to 40 lines looking for the first
non-meta, non-synthetic user message to use as the row's label, falling back to
the short session id.

**Sessions started in a terminal appear here too** — it is the CLI's own store,
not something this extension maintains.

## Refreshing

Sessions live in `~/.claude`, **outside the workspace**, so `nova.fs.watch`
would never fire for them (and would cost a callback on every project file
change). Instead the list is rescanned when the Sessions section becomes
visible, plus on demand from the header's refresh button.

## Row plumbing

- `TreeItem.command` fires on **double-click**. A session row copies its resume
  command; an action row runs its own action via `claudenova.sessionAction`,
  which reads `sessionsView.selection[0]`.
- Session rows are `Collapsed` by default — with 25 rows, expanding all of them
  would bury the list.
- `getParent()` returns the session for action rows so `reveal()` works.

## Gotchas

- `firstPrompt()` uses `readline()` and stops early: transcripts reach megabytes.
- Zero-byte and non-`.jsonl` entries are skipped.
