Compatibility

| Component | Version | |---|---| | DeepSeek Harness | 0.1.1-rc.2 (peer dependencies >=0.1.0-rc.8 <0.2.0) | | Node.js | ^22.19.0 \|\| >=24.0.0 | | Package manager | pnpm@11.7.0 | | Platform | Windows / macOS / Linux (host-only plugin) | | External tools | gh CLI on PATH (authenticated for API reads), npm CLI on PATH |

What you get

• score tool — one target through the five-dimension pipeline; returns the structured risk card, or { kind: 'background', jobId } with background: true.
• /score command — batch scoring of a whitespace/comma-separated target list as a score-batch background job over ctx.jobs, producing a leaderboard snapshot (JSON + Markdown).
• score_report tool — fetch any stored score card (sc_...), leaderboard (lb_...), or the latest leaderboard.
• Five dimensions (weights configurable, defaults sum to 100): install success 25, maintenance 20, documentation 20, security 20, compliance 15.
• Evidence discipline — every dimension records its audit links (source, sanitized detail, observedAt); a dimension without evidence reports no-evidence (score 0, excluded from the weighted total), never a fabricated number.
• Structured results — every record carries schema: "dsh-score/v1" with first-class fields; this is the machine-readable contract downstream tooling consumes.

Quick start

Git channel

dsh plugin --profile web add github:PerryLink/dsh-score#<commit-sha>

The first add fails because pnpm blocks the package's prepare build; copy the exact key pnpm printed into the profile's pnpm-workspace.yaml and re-run:

allowBuilds:
  'dsh-score': true

npm channel

dsh plugin --profile web add dsh-score

Prebuilt packages need no build allowance. Restart the profile, then use score / /score from a session.

Install & uninstall

dsh plugin --profile web add dsh-score     # install (npm) — or the git form above
dsh plugin --profile web remove dsh-score  # uninstall

Configuration

All keys are optional (defaults shown); invalid values fail loudly at load.

Tools & surfaces

score

score(target: string, refresh?: boolean, background?: boolean)

• target — a GitHub repo (github:owner/repo, owner/repo, a git/https URL) or an npm package name.
• refresh: true bypasses the score cache and re-gathers evidence.
• background: true starts a score-batch job and returns its id.

/score <targets...>

Starts one background batch job; progress streams through the job output, and the final line names the leaderboard id for score_report.

score_report(id?)

Returns a score card (sc_...), a leaderboard (lb_...), or — with no id — the latest leaderboard.

}

Scoring: the total is a weighted average over dimensions that gathered evidence (no-evidence dimensions are excluded and renormalized); A ≥ 90, B ≥ 75, C ≥ 60, D ≥ 40, else F, and N/A when nothing had evidence.

Permissions & data

• Only public services are consumed: ctx.subprocess, ctx.jobs, ctx.storageDomain, ctx.tools, ctx.commands.
• Score cards and leaderboards are stored in the score storage-domain (tables scores, leaderboards; latest-leaderboard pointer). When the composition has no storageDomain (e.g. the shipped headless profile), tools still work and score persistence is disabled with a logged reason.
• Child processes inherit the provider's credential-scrubbed environment; gh reads its own credential store. No environment value is ever logged.
• All report/log strings pass through pure sanitizers: token literals, URL credentials, and bearer headers are redacted, and tails are byte-capped.

Security boundaries

• No code execution. The pipeline runs gh api and npm view only; it never installs, builds, or runs a target.
• Argv-only subprocesses. Every CLI invocation is an argv array, never shell-interpreted; repo owner/repo segments are validated against a restricted character set before use in an endpoint.
• Evidence discipline. No score is fabricated: a probe that fails or returns unparsable output yields no-evidence, never a number.
• Detection vs redaction. Secret-leak and malicious-install-script detection share the same pure regexes as redaction; both are unit-tested against extreme inputs.

Known limitations

• Repository probes require gh to be authenticated and network access to GitHub; npm probes require npm and registry access.
• A target without a resolvable GitHub repository cannot be inspected for documentation, security, or compliance (those dimensions report no-evidence).
• Install success depends on dsh-test-drive being mounted and having recorded the target; otherwise it is honestly no-evidence.
• The maintenance "issue response" signal is a proxy (oldest open issue age), not a direct response-time measurement.
• Score results are cached per target; use refresh: true (or wait past cacheMaxAgeMs) to force re-scoring.

Development

pnpm install
pnpm run typecheck && pnpm run typecheck:ci && pnpm test
pnpm run build && pnpm run verify:self-contained && pnpm run verify:artifacts && pnpm pack

• typecheck resolves @deepseek-ai/* through the local harness checkout; typecheck:ci checks against the published 0.1.1-rc.2 types.
• Tests use the real Context/Session/ToolRuntime/LocalJobRegistry/storage stack with a scripted subprocess provider.
• Real-CLI scoring (requires gh/npm on PATH, gh authenticated): invoke score from a mounted profile.
• Release: node scripts/release.mjs <x.y.z> (bumps, stamps CHANGELOG, re-runs the gate, commits + tags; never pushes).
