Multi-persona layer for Claude Code. Per chat (or per CLI call) a different agent role: coder (default), browser, inbox, research, ... Each persona has its own tools, MCP servers, system prompt and workspace. Optional, on top of voice or standalone. Trigger when the user mentions cowork, persona, agent role, multi-agent, bind chat, /cowork-*.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# cowork — personas for Claude Code

cowork is an **optional plugin on top of Claude Code** (and integrates
automatically with voice/bridges if both are installed). It turns a single
coding agent into a pool of roles that switch depending on the chat or CLI
call.

## Mental model

```
chat_profiles[<chat>].persona = "browser"
        │
        ▼
cowork.resolver.resolve("browser", overrides=chat_profile)
        │
        ▼
{cwd, mcp_servers, tools, append_system, permission_mode}
        │
        ▼
claude --mcp-config ... --append-system-prompt ... --add-dir ...
```

## What you, as Claude, need to know

- **Personas live in JSON files** under `operator/cowork/personas/` (bundle)
  or `~/.config/claude-cowork/personas/` (user; shadows the bundle).
- **Schema:** `name`, `description`, `permission_mode`, `allowed_tools`,
  `disallowed_tools`, `append_system`, `model`, `mcp_servers` (dict in
  Claude Code MCP config format), `add_dirs` (list), `needs_keys`,
  `needs_oauth`, `zero_config` (bool).
- **Voice integration is additive:** `chat_profiles[<chat>].persona = "..."`
  is a new optional field next to `permission_mode` / `allowed_tools` / etc.

How to install

The exact contents, by fingerprint

mdr add corvinlabs/corvinos/cowork@sha256:831ab58b36b9bc7a

The line at the top of this page pins the label git:20260915.459047e, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
