Which one, for what

CLI Manager B

Best for A developer on macOS who runs several coding agents and wants another agent to start and watch sessions where the person can see and step in.

Ahead on

  • Schema & documentation, 87 against 42
  • Security & auth, 58 against 50

Watch for

Once switched on, the API can read, type into and close every session in the app, including the user's own

Prime Agent C

Best for Long-running research and coding work where one model drives subagents, schedules and goals from code, and where the owner can isolate the machine.

Ahead on

  • Agent ergonomics, 73 against 63
  • Maintenance & community, 79 against 62
  • Transparency & trust, 64 against 54

Also in its favour

  • No key needed to call it

Watch for

No approval prompts and no sandbox. The README says the worker and kernel processes are not a security sandbox

Verdicts

CLI Manager

An agent can open visible terminal sessions, type into them, wait and read the screen through 12 typed MCP tools or a documented REST API, and the user can take any session back. The API reaches every open session once enabled, the app runs only on macOS, and none of the last 35 CI runs on the main branch passed.

Prime Agent

Budgets for turns, tokens and time bound an autonomous run, and sessions survive a closed terminal through a supervising daemon. Model-written Python and shell commands run with the user's rights, with no approval step and no sandbox, and the Rust build on the main branch ships only as nightly betas.

Before you call either

CLI Manager

  1. Ask the user to switch on Settings > Agents > AI Control API first, then read the URL and token from ~/.climanager/control-api.json
  2. On 409 awaiting_input, read the screen and answer with keys such as ["down","enter"]. Leave folder-trust and permission choices to the user
  3. Stop using a session on 409 disconnected. The user took it back
  4. Treat timedOut: true from wait as still running, not as a failure, and wait again
  5. Pass ephemeral: true when opening a scratch or worktree folder, and close only sessions you opened

Prime Agent

  1. Run it in a disposable clone, container or VM. It executes model-written Python and shell commands with the user's rights and asks nothing first
  2. Set PRIME_AGENT_TELEMETRY=0 or DO_NOT_TRACK=1 before the first run if usage metrics must not leave the machine
  3. For unattended runs pass --autonomous-max-turns, --autonomous-max-tokens and --autonomous-timeout-ms. Reaching a limit does not mean the task succeeded
  4. Headless use is -p with --mode json per the argument parser. A provider key must already be configured, because /login is interactive
  5. The -t/--tools, -nt/--no-tools and -nbt/--no-builtin-tools flags were removed and now fail as unknown options

For companies

Do agents find, use and choose your tools?

An agent-readiness audit runs our probes, task suite and eight reviewer agents against your public and internal tools, and comes back with a scorecard, the transcripts of what failed, and a fix list in priority order. From $2,500, re-run included. We never take payment to move a rank. We do help companies earn one.
