title: Managing Sessions
description: Resume, fork, share, undo, compact, and inspect your coding sessions from Discord.

Every thread is a session, and Kimaki gives you a full set of commands to manage their lifecycle: pick up old ones, branch off, share, and clean up context.

## Resuming and starting

```diagram
/resume <session> ──▶ continue a past session (autocomplete lists recent)
/new-session      ──▶ start a fresh session with a prompt, files, and agent
/last-sessions    ──▶ list the 20 most recently active sessions
```

* **`/resume <session>`** — reopen any earlier session; autocomplete suggests recent ones.
* **`/new-session`** — start a new session, optionally with mentioned files and a chosen agent.
* **`/last-sessions`** — a quick cross-project list of what you were last working on.

## Forking

Forking branches a session so you can explore without disturbing the original.

* **`/fork`** — fork from a chosen earlier message and continue from that point.
* **`/fork-subagent`** — pull a subagent's task out into its own thread to continue it directly.
* **[`/btw`](/docs/btw)** — fork the whole context into a new thread to answer a side question in parallel.

<Aside>
  <Tip>
    Use `/fork` to try an alternative approach from a known-good point. The original thread stays intact, so you can compare both.

## Sharing and identifying

* **`/share`** — generate a **public URL** for the session so anyone with the link can read it.
* **`/session-id`** — show the session ID and an `opencode` command to attach to it from your terminal.
* **[`/diff`](/docs/diff-viewer)** — share the current changes as a diff URL.

## Context management

Long sessions fill the model's context window. Keep them healthy:

* **`/context-usage`** — show token usage and the percentage of the context window used.
* **`/compact`** — summarize the conversation so far to free up context while keeping the gist.

Kimaki also shows context usage automatically in the thread at roughly 10% increments (prefixed `⬦`), and at the end of each assistant turn in a footer like `kimakivoice ⋅ main ⋅ 2m 30s ⋅ 71% ⋅ claude-opus`.

## Undo and redo

* **`/undo`** — revert the last assistant message, including the file changes it made.
* **`/redo`** — reapply the last undone message.

These let you back out a change the agent made without manually reverting files.
