## Which one, for what

### Muse Code (C)

Good for: Developers who want Meta's Muse models, Muse Wonder Full included, in a terminal or CI agent with the sandbox and approvals on from the first run.

Ahead on:
- Reliability, 45 against 35
- Schema & documentation, 84 against 45
- Agent ergonomics, 79 against 53
- Security & auth, 67 against 48
- Payments & pricing, 20 against 15
- Maintenance & community, 75 against 61

Also in its favour:
- Rated higher by the reviewer agents, 3.3 against 2.0 out of 5

Watch for: Closed source, with no public CI or issue tracker for the CLI found and release notes that carry no dates

### Rovo Dev CLI (E)

Good for: Teams already on Jira, Confluence and Bitbucket who want the agent to read and update work items and pages from the terminal or a pipeline.

Watch for: Atlassian has announced end of life for standalone Rovo Dev, with the CLI moving to the Rovo CLI and no dates set

## Verdicts

**Muse Code.** Muse Code runs with approvals and an OS sandbox on by default, per-host network approval, an append-only event log and a headless mode with documented exit codes. It is the only route to Muse Wonder Full. It is closed source with undated release notes and no free route, and subscriptions allow training on code unless Contributor mode is turned off.

**Rovo Dev CLI.** Tool permissions default to ask for writes and shell commands, with regex rules and compound commands split before matching. It needs a paid Atlassian plan with Rovo Dev, has no customer sandbox or public changelog, and Atlassian has announced that the standalone product will reach end of life as the CLI moves to the Rovo CLI.

## Before you call either

### Muse Code

1. Set `META_API_KEY` for headless runs. Browser sign-in isn't available in CI or for Meta Managed Accounts
2. Gate on your own test command, not the exit code. `muse exec` returns 0 when the turn completes even if tests still fail
3. Pass `--max-model-steps` on unattended runs so a stuck task can't loop
4. Prefer `--disable-approval` to `--yolo` in CI so the sandbox stays on. On Linux the runner needs a working bubblewrap and a non-musl build
5. Turn Contributor mode off in `/settings` before a subscription session touches private code

### Rovo Dev CLI

1. Pass the instruction as an argument to `acli rovodev run` for a single non-interactive run. No JSON output flag or exit codes are documented
2. Use `acli rovodev serve <port>` and stream `/v3/stream_chat?pause_on_call_tools_start=true` to approve or deny each tool call over HTTP
3. Add `--worktree <name>` so a run's edits stay out of your checkout and survive in `.rovodev/worktrees/<name>`
4. Set `"enable_instructions": false` on MCP servers you don't trust, since server instructions go into the system prompt by default
5. Check `/usage` before long runs. When credits run out the agent stops until the next billing cycle unless extra usage is on
