Skill2CN · Skill Localization (dsh-plugin-skill2cn)

English | 简体中文

Translate the English description of DSH skills into Simplified Chinese, with one-click restore.

• Single entry point: a dedicated "技能汉化 / Skill Localization" section page in the DSH settings UI (3 tabs: Untranslated / Translated / Model Settings), plus a bottom-right prompt card when new skills appear
• Translation granularity: only the description value in SKILL.md frontmatter; name and the skill body are left byte-for-byte intact
• Write-to-disk: the translation is written straight back to the SKILL.md on disk (rationale in docs/adr/0001-write-to-disk-translation.md); DSH hot-reloads it, so no restart is needed
• Single source of truth: the manifest.json backup ledger. The panel reconciles "disk ↔ ledger" to derive each skill's state: untranslated / translated / no-translation-needed / stale

Install

From the registry (requires Node ≥ 22.13 and pnpm 11):

dsh plugin --profile web add dsh-plugin-skill2cn

From source (requires Node ≥ 22.13 and pnpm 11):

git clone https://github.com/kaluosifa/dsh-plugin-skill2cn.git
cd dsh-plugin-skill2cn
pnpm install
pnpm build   # emits lib/index.js + lib/client.js — the plugin entry (lib/ is git-ignored)
dsh plugin --profile web add .

Replace web with the name of your DSH profile. A link: install (local path) does not run prepare, so no allowBuilds entry is needed — but it also does not build the plugin for you, which is why pnpm build comes first. Restart DSH once after installing (this loads the host half for the first time). After that:

• change the host (src/service.ts, src/core/**) → pnpm build, then restart DSH
• change the client (src/client/**) → pnpm build, then reload the browser
• upgrade from source → git pull && pnpm install && pnpm build (restart DSH if the host half changed)

Uninstall

Click Restore All on the Translated tab first. Write-to-disk changes are not undone automatically by uninstalling (ADR-0001, Consequences).

dsh plugin --profile  remove dsh-plugin-skill2cn

The ledger at $DSH_HOME/skill2cn/manifest.json is left behind (harmless, safe to delete by hand).

Development

pnpm install
pnpm dev          # tsdown watch (tsc transpiles standard decorators into lib-tsc first, then bundles)
pnpm test         # core unit tests (vitest)
pnpm typecheck    # both tsconfigs: host + client
pnpm build        # emits lib/index.js (host ESM) + lib/client.js (closure-factory CJS)

Requirements: Node ≥ 22.13 and pnpm 11. (pnpm 11 requires Node ≥ 22.13 and is
also the version that produced pnpm-lock.yaml.)

Build pipeline

The @Remote decorator needs TypeScript's standard-decorator transpilation, which esbuild/tsdown does not perform, so the build runs in two steps:
tsc -p tsconfig.build.json emits lib-tsc/, then tsdown bundles from the lib-tsc/index.js entry into lib/index.js.
lib-tsc/ is an intermediate artifact (already covered by .gitignore and regenerated by pnpm build).

Translation routing

The Model Settings tab offers three routes:

1. Follow the current DSH session route (default) — reuses the provider/model of the most recent session request. If no route has been captured yet, Test asks you to send a session message first.
2. Use a configured provider/model — the dropdown is populated from ctx.remote.llm.listConfigurableProviders(); Discover models calls discoverModels on the provider's settingsNs. Some providers register no discovery capability, in which case you can type the model name manually.
3. Custom endpoint — pick a protocol (OpenAI-compatible / Anthropic-compatible) under Advanced, then fill in Base URL / API key / model name. Both are non-streaming:
   - OpenAI-compatible → POST {baseURL}/chat/completions (Authorization: Bearer)
   - Anthropic-compatible → POST {baseURL}/messages (sends both x-api-key and Authorization: Bearer so official and proxy endpoints both work; anthropic-version: 2023-06-01, max_tokens required)

The Base URL must include the version segment (e.g. https://api.deepseek.com/v1 or https://api.anthropic.com/v1) — the resource path is appended by the plugin. Note this differs from how you configure an anthropic provider inside DSH, where the base excludes /v1 (the SDK owns the path); copying that style here gives you a 404.

Test runs one real, small translation through the current route and reports a verdict first: a green "configuration succeeded" or a red "configuration failed", with details on the second line (translation + latency + the actual model name; on failure, the host's original reason). The sample sentence is fixed in the host (Use when translating skill descriptions into Simplified Chinese.) — deliberately this plugin's own self-description, so a passing test also demonstrates that the route can translate the very thing you need translated, and the skill identifier in it doubles as a check of the built-in "do not translate identifiers" rule.

How it works

Translation is write-to-disk (ADR-0001): the plugin reads the target SKILL.md, records the English original in the backup ledger, calls the LLM, then rewrites only the description: line of the frontmatter. DSH's chokidar watcher fires skills/change, so the next model step already sees the Chinese description. The ledger — not any guess about a file's language — is the only thing that decides translated vs. untranslated.

Known limitations

• The workspace group follows the session workspace (session.header.cwd; falling back to the most recent session with a header, and only then to the process cwd). So "workspace" means the project you have open in DSH, not the directory DSH was started from — starting DSH from inside a checkout does not make that checkout's own project skills a translation target.
• Enumeration uses the ctx.skills registry winner set: skills that lost a same-name override, and in-memory provider skills with no file on disk, do not appear on the panel.
• The "no translation needed" heuristic treats a description as Chinese when it has ≥ 4 CJK ideographs and at least half as many CJK characters as Latin letters. Chinese descriptions routinely carry identifiers and product names (dingtalk-*, Shadcn/ui, utility-first, spec/tickets), which a strict "more CJK than Latin" rule would misjudge as needing translation. See the acceptance record for the real-data verification.
• The "configured route" dropdown lists DSH's provider catalog, which is not the same as the providers with a registered adapter on your machine: picking an unregistered one makes Test report no adapter registered for provider "..." (surfaced verbatim rather than swallowed).
• Skills from the plugin package source are overwritten when the npm package is upgraded or reinstalled; their badge carries a ⚠️ and the automatic reconcile on panel open handles the fallout (silently clearing the record or marking it stale).
