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.\n\n**Mirror CLI.** Mirror CLI is Apache-2.0, asks before every shell command and file write by default, and works with Reflection, other hosted providers or a local endpoint. It is a one-day-old 0.1.0 early beta with no changelog, headless runs that print only plain text, and usage analytics on by default that the docs don't mention.\n\n## Before you call either\n\n### HarnessRouter\n\n1. Name the harness yourself. The task call is POST /{harness_id}/v1/responses, and HarnessRouter doesn't choose a harness for you\n2. 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\n3. Call cancel to stop work. Closing the SSE connection leaves the agent running and billing\n4. Keep the Workspace API key on the server. The docs forbid calling the API from a browser with it\n5. Check each tool's enforcement in GET /v1/bases. On bases marked instruction, disabled_tools is a request to the model, not a block\n\n### Mirror CLI\n\n1. Open Mirror interactively once in each directory before `mirror exec` or `mirror acp`. Both refuse to run until the usage and folder notices are accepted\n2. Pass `--approval-mode auto` to `mirror exec` only inside a container or VM. In manual mode, calls that need approval fail, and approval isn't a sandbox\n3. Set `--max-iterations` on unattended runs. Turns are unlimited by default\n4. Check the result with your own tests. `exec` returns 0 whenever it prints an answer\n5. Never share logs recorded with `--log-level debug`. The docs say they contain request headers with the API key\n\n## Questions\n\n### Which is better for AI agents, HarnessRouter or Mirror CLI?\n\nMirror CLI scores 54.2 (C) on agent readiness against HarnessRouter's 53.2 (D), and leads in 2 of 7 scored categories. HarnessRouter leads on schema \u0026 documentation, agent ergonomics, maintenance \u0026 community and transparency \u0026 trust.\n\n### Are HarnessRouter and Mirror CLI open source?\n\nYes. HarnessRouter is open source (Apache-2.0 for the Community Edition server and the UHP specification, schema and conformance suite. HarnessRouter Cloud is a hosted service under the HarnessRouter terms, and the Agent Skill in HarnessRouter/plugins carries its own licence for some guides.). Mirror CLI is open source (Apache-2.0).\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/harnessrouter-vs-reflection-mirror.json, and with the fewest tokens: https://www.anchorterminal.com/compare/harnessrouter-vs-reflection-mirror.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"harnessrouter\", \"b\": \"reflection-mirror\"}`.
