          "2026-09-08. CVE-2026-82533 (CVSS 9.6, published by VulnCheck). The local HTTP agent-control API trusted a client-supplied loopback Host header, so a sandboxed tool process could reach it, escape the sandbox and turn off approvals, and a tunnelled port exposed it remotely. Fixed in 0.1.2-alpha.1 with commit 3e24087 per the NVD record. Fixed, inside six months, -2. https://nvd.nist.gov/vuln/detail/CVE-2026-82533",
          "2026-09-28 to 2026-10-16. Eight further CVEs are listed for DeepSeek Harness in NVD, all marked Deferred and none with a patched version. Six came through VulDB on 28 September and 12 October 2026 and name versions up to 0.1.0-rc.7, 0.1.1-rc.2, 0.1.5-rc.3 and 0.1.7-rc.2, with CVSS 3.1 scores of 3.1 to 6.3. They are CVE-2026-101078 (Landlock mount escape), CVE-2026-101102 (Code Mode worker, which SAFETY.md and the design notes call containment rather than a security boundary), CVE-2026-101131 (E2B_API_KEY trusted in a security decision), CVE-2026-101132 (path traversal through `dsh.bundle.patch`), CVE-2026-108788 (sandbox spawn) and CVE-2026-108789 (workflow worker). Each says the vendor was contacted early and did not respond. CVE-2026-95182 (CVSS 10.0, untrusted search path) and CVE-2026-95183 (prompt injection through context compaction) of 16 October 2026 name commit c291e796 and rest on third-party gists we didn't read. Read the way the PicoClaw note was. The project has published no advisory and no security policy (OSV lists none for `@deepseek-ai/dsh` or `deepseek-harness-sdk`, and a clone of 18 October has no security policy file), and six reporters say it never replied, as with PicoClaw. We read all eight NVD records but none of the write-ups. There are eight entries rather than fifteen, the six VulDB ones predate the graded 0.2.0-rc.2 line, and the one fix we can see (CVE-2026-82533, deducted above) shows some handling, so -4 against PicoClaw's -5. https://services.nvd.nist.gov/rest/json/cves/2.0?keywordSearch=deepseek-harness"

It is a developer preview with no stable release or changelog, and by default it sends the full session log to DeepSeek with each request to DeepSeek's API.\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### DeepSeek Harness (dsh)\n\n1. Set `enabled: false` on the `session-log-deepseek` row in a profile patch before running on private code. Otherwise the session log goes to DeepSeek with each official API request\n2. Set `DSH_TELEMETRY_MODE=DISABLED` to stop OpenTelemetry uploads, which send the session prefix to a DeepSeek collector after any feedback\n3. Treat exit code 1 and the `turn_end` reason as failure. A `--json` stream can end with a `final` event for a failed run\n4. Run in a disposable container or VM. The sandbox doesn't confine reads or network, and SAFETY.md says the project has had no security audit\n5. Pin the version. npm `latest` (0.2.0-rc.2) and `next` (0.2.1-rc.2) differ, DeepSeek's changelog asks for 0.2.1-rc.1 or later, and the README warns of breaking changes\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, DeepSeek Harness (dsh) or Mirror CLI?\n\nMirror CLI scores 54.2 (C) on agent readiness against DeepSeek Harness (dsh)'s 49.2 (D), and leads in 3 of 7 scored categories. DeepSeek Harness (dsh) leads on schema \u0026 documentation, agent ergonomics and maintenance \u0026 community.\n\n### Are DeepSeek Harness (dsh) and Mirror CLI open source?\n\nYes. DeepSeek Harness (dsh) is open source (MIT). Mirror CLI is open source (Apache-2.0).\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/deepseek-harness-vs-reflection-mirror.json, and with the fewest tokens: https://www.anchorterminal.com/compare/deepseek-harness-vs-reflection-mirror.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"deepseek-harness\", \"b\": \"reflection-mirror\"}`.
