Install verification: Ecosystem plugin: installs via dsh plugin add but declares no dsh.bundle and mounts no plugin capability — the L1-L5 install ladder does not rate it; the security scan still runs.Install verification details →

What it doesAI

Provides pure mathematics tools for agents: search examples, compute exactly, verify proofs.

Search for mathematical examples and counterexamples
Perform exact computations
Independently check what a result proves

aiAI

Capability tags are AI-inferred or rule-extracted from the README (see badge) — vocabulary-limited, not install-verified. AI = inferred; README = literal keyword from the readme.

Installation

dsh plugin --profile web add jacobian

verified 0.22.0

Install method: npm · runtime test inconclusive (L5 unknown)

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.

External credentials (plugin-level): none detected

Install compatibility matrix (rows = plugin versions〔latest 5〕, columns = dsh versions〔latest 5〕)

L1–L3 are plugin-level static conclusions (baseline, identical across dsh versions): evidence is stored once per plugin.

Only the latest 3 published versions are shown; source-snapshot (commit hash) groups, unstated groups and older versions are omitted — the full archive stays in the data layer (snapshot/unstated groups appear only when a plugin has no published version).

Plugin notes

What is jacobian?

jacobian is an ecosystem plugin maintained by @morluto: it installs via dsh plugin add but declares no dsh.bundle and mounts nothing — installing it adds no plugin capability; use the source repository directly. It is cataloged on dsh.so as a AI Models entry, with a public source repository and automated static security scan.

How do I install jacobian?

This is an ecosystem plugin: it installs via dsh plugin add but declares no dsh.bundle and mounts nothing — installing one adds no plugin capability; use the source repository directly. Its level reads L5 · Ecosystem plugin; the security scan still runs.

How does the security scan relate to a manual audit?

The scan is automated static analysis of the repository source — a scalable first line of defense that can produce false positives and miss context; it is not a manual security audit. Before using a plugin, review the repository and installed permissions, and combine the scan with the verification level (L4/L5) and health signals.
