+import { Image } from 'astro:assets';
+import studioRuns from '../../../../assets/screenshots/studio-runs.png';
+import studioProjects from '../../../../assets/screenshots/studio-projects.png';
+
+The `studio` command launches a web-based dashboard for browsing evaluation runs, inspecting individual test results, and reviewing scores.
+
+<Image src={studioRuns} alt="AgentV Studio showing evaluation runs with pass rates and scores" />
+
+## Usage
+
+```bash
+agentv studio
+```
+
+Studio auto-discovers results from `.agentv/results/` in the current directory and opens at `http://localhost:3117`.
+
+You can also point it at a specific results file:
+
+```bash
+agentv studio .agentv/results/runs/2026-03-30T11-45-56-989Z/index.jsonl
+```
+
+## Options
+
+| Option | Description |
+|--------|-------------|
+| `--port`, `-p` | Port to listen on (flag > `PORT` env var > 3117) |
+| `--dir`, `-d` | Working directory (default: current directory) |
+| `--multi` | Launch in multi-project dashboard mode |
+| `--add <path>` | Register a project by path |
+| `--remove <id>` | Unregister a project by ID |
+| `--discover <path>` | Scan a directory tree for repos with `.agentv/` |
+
+## Features
+
+- **Recent Runs** -- table of all evaluation runs with target, experiment, timestamp, test count, pass rate, and mean score
+- **Experiments** -- group and compare runs by experiment name
+- **Targets** -- group runs by target (model/agent)
+- **Run Detail** -- drill into a run to see per-test results, scores, and evaluator output
+- **Human Review** -- add feedback annotations to individual test results
+
+## Multi-Project Dashboard
+
+By default, Studio shows results for the current directory. The multi-project mode lets you view results across multiple repositories from a single dashboard.
+
+### Registering Projects
+
+Register projects one at a time:
+
+```bash
+agentv studio --add /path/to/project-a
+agentv studio --add /path/to/project-b
+```
+
+Each path must contain a `.agentv/` directory. Projects are stored in `~/.agentv/projects.yaml`.
+
+### Auto-Discovery
+
+Scan a parent directory to find and register all projects:
+
+```bash
+agentv studio --discover /path/to/repos
+```
+
+This recursively searches (up to 2 levels deep) for directories containing `.agentv/` and registers them.
+
+### Launching the Dashboard
+
+Once projects are registered, launch the multi-project dashboard:
+
+```bash
+agentv studio --multi
+```
+
+If you have any registered projects, `--multi` is automatically enabled. The landing page shows a card for each project with run count, pass rate, and last run time. Click a project to view its runs.
+
+<Image src={studioProjects} alt="AgentV Studio multi-project dashboard showing project cards with pass rates" />
+
+### Removing Projects
+
+Unregister a project by its ID:
+
+```bash
+agentv studio --remove my-project
+```
+
+Project IDs are derived from the directory name (e.g., `/home/user/repos/my-project` becomes `my-project`).
