Verification & Compatibility

Grouped by plugin version: each card lists the dsh versions actually tested against that artifact version and their install verdicts (L5 wins). Untested combinations are omitted — absence means untested, never assumed compatible. L1–L3 are a plugin-level static archive (independent of the dsh version — the same verdict on every dsh row): they sit in each row's level grid next to L4/L5, marked "static", while their evidence is stored once per plugin inside that row's "checks & evidence" instead of being duplicated per version.

Security Report

Two automated layers, neither a manual review: a static scan (per-plugin rule checks) and a model-driven dynamic security audit that covers only the subset static-flagged at warn or above and never executes plugin code.

lowDiagnostic log writes session ID suffix and engine error text to a home-directory filesrc/index.ts:70
On mount, on the first pre-step crossing the trigger, and on compaction failure, `diag()` appends `sessionId` (last 8 chars of `session.id`) and `outcome.reason` (raw compaction-engine error, truncated to 180 chars) to a fixed file in the user's home directory (line 72: `appendFileSync(file, ...)`). The path is overridable via the `DSH_FLOOR_LIMITER_LOG` environment variable and the file is created with default umask permissions. No conversation text is deliberately logged, but engine error messages may embed content, and raw newlines in `reason` can forge extra log lines. Impact is limited to
lowVendored schemastery bundle contains new Function on string schema.callback (unreachable here)lib/index.js:412
The shipped bundle inlines cosmokit/schemastery, whose `Schema()` constructor evaluates a string `callback` with `new Function`. This is a code-execution primitive, but the floor-limiter schema (src/settings.ts) only builds `object/boolean/number` schemas with `default/min/step/volatile` and never passes a string callback or `refs`; `Schema.resolve` used on config does not construct schemas. The path is therefore dead code in this plugin, carried only because the build bundles its dependency.

Host plugin only counts user floors and calls the official compaction seam; bundled `new Function` in vendored schemastery is unreachable and only a local diagnostic log is written.

Rule: the dynamic audit can only raise risk, never lower it (raise-only, never an exemption); a wrong raise is withdrawn by human review and the tier falls back to the static verdict. Overall verdict = the stricter of the two layers.

Disclaimer: the static scan and the dynamic security audit are both automated analysis, not a security guarantee. Always review what you install.

Plugin notes

What is the @MengXinSu/floor-limiter DeepSeek Harness plugin?

@MengXinSu/floor-limiter is a DeepSeek Harness plugin maintained by @MengXinSu. It is cataloged on dsh.so as a Storage plugin, with a public GitHub source, declared install command, and automated static scan results; plugins static-flagged at warn or above also carry a model-driven dynamic security audit record.

How do I install @MengXinSu/floor-limiter?

Run dsh plugin --profile web add github:MengXinSu/floor-limiter in a DeepSeek Harness (dsh) environment. This exact command has been verified by a real install inside an isolated windows-acl sandbox (L4) plus web smoke testing (L5).

How does the security scan relate to a manual audit?

Both layers are automated, not a manual audit: the static scan is heuristic analysis of the repository source (it can produce false positives and miss context), and the dynamic security audit has a model read the harvested source context with secret files stripped and content redacted inline — plugin code is never executed. The dynamic audit only covers plugins static-flagged at warn or above, and its conclusion can only raise the combined verdict, never exempt it. Neither layer is a manual security audit or an endorsement; before using a plugin, review the repository and installed permissions, and combine both with the verification level (L4/L5) and health signals.

"DeepSeek Harness (dsh) is an open-source agent harness developed by DeepSeek AI. It uses an architecture where everything is a plugin, and is powered by Cordis."
