@perrylink/dsh-plugin-kit

Shared zero-runtime-dependency toolkit for the PerryLink DSH plugin repositories. The per-project audit found 20+ of the 33 plugins hand-rolling the same Provider seam and duplicating the same sanitize/pricing/verdict shapes, so this package extracts all of it — the pluggable Provider seam, the fail-closed approval and adaptive session-event gates, the mechanical verify scripts, and the shared sanitize/pricing/judge pure modules — into one ESM + TypeScript package.

• 1024 store channel: npm i -g dsh1024 once, then dsh1024 plugin --profile web add @perrylink/dsh-plugin-kit (counts toward the deepseek1024.com install ranking).

The same run, animated.

Compatibility

• DSH harness: the kit imports nothing from @deepseek-ai/* at runtime. @deepseek-ai/cordis (^4.0.5-alpha.1), @deepseek-ai/schemastery (^3.18.5-alpha.1), and the @deepseek-ai/dsh-* packages are optional peer dependencies in the >=0.1.2-rc.1 <0.2.0 || >=0.1.5-alpha.1 <0.2.0 || >=0.1.6-0 <0.2.0 || >=0.1.7-0 <0.2.0 || >=0.2.0-0 <0.3.0 || >=0.2.1-0 <0.3.0 band the PerryLink plugin repos share; they exist only for type interop. Verified 2026-09-11 against the dsh-v0.1.7-alpha.1 master checkout (full gate chain + profile install smoke), and re-verified 2026-10-05 against the dsh-v0.2.1-alpha.1 checkout (full gate chain + profile install smoke).
• Node: ^22.19.0 || >=24.0.0, ESM only.
• Wire compatibility: names and shapes mirror dsh-mask (sanitize), dsh-budget (pricing), and dsh-auto-review (judge and the fallbackPolicy vocabulary), so migration is mechanical.

What you get

• Zero runtime dependencies — the pure core (seam, gates, shared) is browser-safe.
• ESM + strict TypeScript — JSDoc contracts on every module; strict, noUncheckedIndexedAccess, exactOptionalPropertyTypes.
• Fail-closed and adaptive gates — approval never defaults to a grant; session-event appends degrade gracefully on hosts that reject unknown event types.
• A new-plugin skeleton — template/ with cordis.yml, a three-role src/index.ts (Service Definition / Provider / Consumer), a test, and the shared Renovate preset.

Quick start

dsh plugin --profile web add github:PerryLink/dsh-plugin-kit

From npm:

pnpm add @perrylink/dsh-plugin-kit

From git (the prepare script builds lib/ using only production dependencies):

pnpm add github:PerryLink/dsh-plugin-kit

Replace a hand-rolled registry in one step:

import { ProviderRegistry } from '@perrylink/dsh-plugin-kit/seam'

const registry = new ProviderRegistry<Detector>({
  default: { name: 'regex', impl: new RegexDetector() },
})
ctx.effect(() => registry.register('ner', new NerDetector()))
const active = registry.use('ner') ?? registry.use()

Install & uninstall

As a library, install is pnpm add (see Quick start). The package also ships an intentionally empty dsh.bundle.patch layer (cordis.patch.yml), so it flows through the harness bundle channel when a profile wants the kit mounted as a package:

# npm channel (published releases)
dsh plugin --profile web add @perrylink/dsh-plugin-kit

# git channel (latest master)
dsh plugin --profile web add github:PerryLink/dsh-plugin-kit

Remove with:

pnpm remove @perrylink/dsh-plugin-kit

Nothing registers global state: uninstall is exactly the reverse of install.

Configuration

No runtime configuration: the gates and helpers are pure functions. The only configuration surface is cordis.patch.yml, the bundle-patch layer shipped for harness profile composition; it mounts no plugin row (the kit is a library) and documents how consuming plugins add their own rows.

Tools & surfaces

| Subpath | Purpose | |---|---| | seam | ProviderRegistry<T> — reversible, fail-loud named provider registry. | | gates | applyFailClosed; makeEventGate / maybeAppendSessionEvent / probeIgnorableAppend. | | shared | sanitize (Stripper, redactText, redactMapping, sanitizeText, sanitizeUrl), pricing (BUILTIN_PRICES, estimateUsageCost, tokenCarbon, latencyStats, formatMoney, formatTokens), judge (parseVerdict, VERDICT_SCHEMA, riskExceeds). | | verify | Mechanical CI gates (verify-license, verify-readme-languages, verify-seam) with a VerifyReport and a non-zero-exit CLI: node lib/verify/cli.js all . | | template/ | New-plugin skeleton (cordis.yml, three-role plugin, test, README, renovate.json5). | | root barrel | Re-exports all of the above. |

Permissions & data

The kit performs no I/O, no network access, and no subprocess spawns on its own. Stripper keeps placeholder→original mappings in memory only, and stats()/redactMapping() never emit plaintext; a consumer that persists a mapping owns that decision and its storage permissions.

Security boundaries

• sanitize/redact* are display hygiene, not a security boundary: they reduce leakage into logs and results, they do not authenticate or authorize.
• Approval gates are fail closed by default (rejected); the only grant path is an explicit allow-once opt-in.
• Session-event appends the host refuses are skipped, never retried in a way that could break session resume.
• Report vulnerabilities via GitHub Security Advisories — see SECURITY.md.

Known limitations

• Hosts whose Session.append third argument is a SurfaceIntent (0.1.2-rc.1) throw validateNext on the ignorable-envelope probe; the gate degrades to skip-unknown, so audit events are dropped (fail closed) rather than logged on those hosts.
• 0.1.2-rc.1 (adapted 2026-09-02): the session envelope keeps its ignorable field for stored-log read compatibility only - Session.append still cannot stamp it, so audit-gate behavior is unchanged.
• The kit ships no browser UI half; it is a library consumed by the Host (and optionally Client) halves of other plugins.

Development

pnpm test                 # vitest unit tests
pnpm run build            # emit lib/ + declarations (also run by prepare)

Topics

This repository is also the maintenance hub for the 33 plugin repos: scripts/sync-peer-range.mjs re-pins the shared peer band across all repos in one command, renovate/default.json5 is the shared Renovate preset every repo extends, .github/workflows/npm-publish.yml is a reusable tag-triggered publish workflow (needs only an NPM_TOKEN secret), and data/repos.json is the ecosystem registry consumed by the portal. See docs/ecosystem-tooling.md.

PerryLink DSH Plugin Family

This project is one of the 33 actively maintained DeepSeek Harness plugins from PerryLink — the roster is 42, of which 6 are frozen and 3 retired; every one keeps its row below, with the reason in the Status column. If this one helps you, the others likely will too:
