## Which one, for what

### HarnessRouter (D)

Good for: A product team that wants to run Codex, Claude Code, Hermes or 23 other harnesses server-side behind one task, session and file contract, and switch between them by changing an ID.

Also in its favour:
- A hosted endpoint, with nothing to install

Watch for: No status page found (status.harnessrouter.ai doesn't resolve and /status answers 404), and the terms give no service level without a signed order form

### Kilo Code CLI (BB)

Good for: Developers who want an open-source terminal agent with per-tool permission rules, an optional sandbox and a choice of provider, and the same engine in VS Code and JetBrains.

Ahead on:
- Reliability, 85 against 35
- Schema & documentation, 90 against 83
- Security & auth, 64 against 58
- Payments & pricing, 50 against 25
- Maintenance & community, 87 against 72

Also in its favour:
- Agent-ready, a grade of BB or better
- Free to start without a card

Watch for: Telemetry to PostHog is on by default, attaches the conda client ID since 7.8.10, and the privacy policy doesn't mention it

## Verdicts

**HarnessRouter.** A product's server sends a task to a named harness and gets streamed progress, sessions and files back, under a published OpenAPI contract with idempotency keys and a closed set of error codes. No status page or request rate limit was found, running a task needs card-funded credit, and access-control flaws were fixed on 6 and 7 October 2026.

**Kilo Code CLI.** Shell commands ask before running by default, and an optional operating-system sandbox blocks writes outside the workspace and outbound network. Telemetry to PostHog is on by default and the sandbox is off, so an unattended `kilo run --auto` approves everything not denied unless both are configured first.

## Before you call either

### HarnessRouter

1. Name the harness yourself. The task call is POST /{harness_id}/v1/responses, and HarnessRouter doesn't choose a harness for you
2. Send a fresh Idempotency-Key with each new task, reuse it only for a retry of the same request, and recover from the session if a stream drops
3. Call cancel to stop work. Closing the SSE connection leaves the agent running and billing
4. Keep the Workspace API key on the server. The docs forbid calling the API from a browser with it
5. Check each tool's enforcement in GET /v1/bases. On bases marked instruction, disabled_tools is a request to the model, not a block

### Kilo Code CLI

1. Set `sandbox.enabled` to true in the global `kilo.jsonc` before `kilo run --auto`. `--auto` approves every permission request not explicitly denied
2. Set `experimental.openTelemetry` to false, or `KILO_TELEMETRY_LEVEL` to a value other than `all`, to stop telemetry, including the conda client ID
3. Add needed hosts to `sandbox.allowed_hosts` in global config. MCP tool calls are unavailable while network restriction is on
4. Without `--auto` a non-interactive run rejects every permission prompt and exits 1
5. Confine subagent writes with a session-level edit rule. From 7.8.13 a custom agent's own `edit` denies no longer bind the subagents it starts
