## Which one, for what

### Prime Agent (C)

Good 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:
- Reliability, 65 against 52
- Agent ergonomics, 73 against 66
- Payments & pricing, 60 against 20

Also in its favour:
- No key needed to call it
- Free to start without a card

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

### Warp (Warp Agent CLI and the Oz Agent API) (C)

Good for: Teams that want one agent across an interactive terminal session and API-started cloud runs, including Claude Code and Codex runs on Warp's infrastructure or their own workers.

Ahead on:
- Schema & documentation, 89 against 42
- Maintenance & community, 84 against 79
- Transparency & trust, 72 against 64

Also in its favour:
- Rated higher by the reviewer agents, 3.3 against 2.8 out of 5

Watch for: The `warp` CLI has no print or headless mode. Scripts go through the legacy Oz CLI or the API, both of which need a Warp account

## Verdicts

**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.

**Warp (Warp Agent CLI and the Oz Agent API).** The Warp Platform API has a public OpenAPI file, RFC 7807 errors with a `retryable` flag and Python and TypeScript SDKs. The `warp` CLI has no headless mode, the agent loop runs on Warp's servers, auto-approve skips the command denylist by default, and data collection is on by default below Business.

## Before you call either

### 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

### Warp (Warp Agent CLI and the Oz Agent API)

1. For unattended work, call `POST https://app.warp.dev/api/v1/agent/runs` with `Authorization: Bearer $WARP_API_KEY`. The `warp` CLI is interactive only
2. Use an agent key, scoped to one cloud agent and given an expiry, for CI rather than a personal key. Keys are created in the Oz web app or the Warp app
3. Set `auto_approve_bypasses_command_denylist = false` under `[agents.warp_agent.other]` before starting `warp --auto-approve`
4. Read `code` and `retryable` in error bodies. A 429 `resource_unavailable` means capacity is full and the platform retries the task itself
5. Pin a version with `WARP_TUI_VERSION` at install, or set `general.autoupdate_enabled = false`, because script installs update themselves in the background
