A sidebar for Claude Code. It shows what the session is doing while you work: context usage, git state, the files Claude touched, the todo list, running subagents, and a short recap of the conversation.
In a Claude Code terminal session:
/plugin install mission-control --marketplace dphase/claude-mission-control
Answer y to add the marketplace, then press Enter to install at the user scope. The sidebar opens on its own once the terminal is wide enough.
To remove it:
/plugin uninstall mission-control
- Header: session title, model, and how long the current turn has been running.
- Context: percent of the context window used, a per-turn sparkline, and session cost.
- Git: branch, ahead/behind, staged/changed/new counts, line churn, and the last commit.
- Modified Files: changed files, with the ones Claude edited this session marked.
- Todo: Claude's task list, with the active task highlighted.
- Agents: running subagents with their type, step count, current tool, and an ETA learned from past runs of the same type.
- Recap: what you asked, what's done, and what's next. Haiku writes it after each turn from the last few messages.
- Artifacts: pages Claude published, read or opened this session, newest first. Click one to open it in your browser.
Click a section header to fold it.
The Artifacts icon is a Nerd Font glyph. Use a Nerd Font, or a terminal that bundles the symbols (Ghostty does); otherwise it draws as an empty box.

claude --plugin-dir ~/path/to/claude-mission-control
The session watches the folder and reloads the mod when you save. claude plugin validate . checks the manifest and the hooks module.
