Plugins
Seven bundled plugins extend the studio — skills, diagrams, dictation, prompt templates, and more. Toggle any of them in Settings.
Plugins customize the studio itself — panes, transcript decorations, composer actions, commands, and providers. Atelier ships seven, enabled by default and managed in Settings ▸ Plugins: flip one off and its UI disappears immediately; flip it back on and it returns. Each entry lists the plugin's version, author, and capabilities.
The bundled seven
| Plugin | What it gives you |
|---|---|
| Skills | Adds a Skills section to the Tasks rail listing every skill your projects define, with a viewer and editor for each SKILL.md. Agents pick skills up through Claude Code; this plugin is how you browse and edit them. |
| Mermaid | Renders mermaid code fences in transcripts as live diagrams once the message settles, and previews .mmd files — flowcharts from your agent, drawn instead of dumped. |
| Run Command | Puts a Run action on shell code blocks in transcripts. One click opens a terminal at the session's folder and executes the block — no copy-paste. |
| Open Links In-App | Routes http(s) links in transcripts to the built-in browser pane instead of your external browser, so previews stay inside the studio. |
| Sent Messages | A pane listing every message you have sent in a session — open it from the command palette (Show messages I sent, ⌘⇧M); click a row to copy it. Great for reusing a prompt that worked. |
| Prompt Library | Saved prompt templates. Save the current draft via the composer's ⚙ menu (Save draft as template…) or /prompt save <name> <text>, then insert with /prompt <name> — autocomplete kicks in from /pro…. |
| Voice | On-device dictation behind the composer mic, powered by Whisper. First use downloads the model once (~466 MB, with a consent prompt); manage or delete it in Settings ▸ Voice, and select Voice as the Voice input provider in Settings ▸ Providers. Audio never leaves your Mac. |
Building your own? A public plugin API — and a marketplace to share through — is on the roadmap. Today's set is fixed to the bundled seven.
