A workspace key could also read, change and delete another workspace's harnesses, sessions and responses and mint an organisation-wide key (\"reported privately three times\"). All were fixed within days and described in the source. The advisory pages couldn't be read (GitHub answered 403), so whether they're published is unchecked, and the deduction is lower than an open cross-tenant flaw would get.

The bubblewrap environment builds its `bwrap` command without `--clearenv` or `--unshare-net`, so commands inherit the host environment, model keys included, and can send them out over the network after a prompt injection in task content. Confirmed in src/minisweagent/environments/extra/bubblewrap.py at 2.4.6 and on main (3 September).

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**mini-swe-agent.** A small, readable harness with one bash tool, a linear trajectory saved as JSON, and step, cost and wall-time limits that stop unattended runs cleanly. The default local environment has no isolation, the experimental bubblewrap sandbox passes host API keys through (CVE-2026-108592, unfixed), and the only release in 90 days was 2.4.6 on 23 July 2026.\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### mini-swe-agent\n\n1. Run with `-y --exit-immediately` for unattended use. Without `--exit-immediately` it waits for input when the agent finishes\n2. Set `MSWEA_CONFIGURED=true` and `MSWEA_MODEL_NAME` first, or the first run stops at an interactive setup prompt\n3. Read `info.exit_status` in the `-o` trajectory file. A run that hits its limits still exits normally\n4. For untrusted repositories use `-c mini.yaml -c environment.environment_class=docker -c environment.image=\u003cimage\u003e`. The local and bubblewrap environments both expose host variables\n5. Strip model keys from the environment commands see, since the local environment passes every host variable to each command\n\n## Questions\n\n### Which is better for AI agents, HarnessRouter or mini-swe-agent?\n\nmini-swe-agent scores 56.7 (C) on agent readiness against HarnessRouter's 53.2 (D), and leads in 2 of 7 scored categories. HarnessRouter leads on schema \u0026 documentation, maintenance \u0026 community and transparency \u0026 trust.\n\n### Are HarnessRouter and mini-swe-agent 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.). mini-swe-agent is open source (MIT).\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/harnessrouter-vs-mini-swe-agent.json, and with the fewest tokens: https://www.anchorterminal.com/compare/harnessrouter-vs-mini-swe-agent.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"harnessrouter\", \"b\": \"mini-swe-agent\"}`.
