dsh-update-checker

A permanent Cordis plugin for the DeepSeek Harness Web GUI that auto-checks for new DeepSeek Harness releases AND installed third-party plugin updates (the former standalone dsh-plugin-checker was merged in v1.1.0), asks the user, and one-click updates with success/failure feedback.

• Host half (lib/index.js) registers HTTP routes:
  • GET /dsh-update-checker/status.json — fetches the latest @deepseek-ai/dsh version from the npm registry, reads the locally installed version (from the deployment's node_modules), compares them with semver semantics, and returns a JSON status (including the persisted suppressUpToDate flag).
  • POST /dsh-update-checker/suppress — persists the "don't remind me again" flag for the up-to-date banner (requires { "confirm": true }).
  • POST /dsh-update-checker/update — complete update: backs up the deployment lockfile + @deepseek-ai version manifests, runs npm install @deepseek-ai/dsh@latest in the deployment root, then defensively syncs changed @deepseek-ai packages into $DSH_HOME/profiles/node_modules (skipped for junction-linked packages, which the running Web app resolves through). Requires { "confirm": true }; supports { "dry": true } to preview without executing.
  • POST /dsh-update-checker/restart — restarts the dsh web service (spawns a PowerShell helper that kills the port listener and relaunches /start-dsh.cmd; the port and launcher path are derived at runtime). Requires { "confirm": true }.
  • GET /dsh-update-checker/plugins.json — scans installed third-party (non-builtin) plugins (composition rows + dsh field, layout-agnostic), compares each against npm latest (semver), returns update status.
  • POST /dsh-update-checker/plugin-update — updates one plugin via temp-dir npm install + copy (never touches other packages in profiles/node_modules, junction-aware, backs up the old version first). Requires { "confirm": true, "name" }.
• Client half (lib/client.js) is a web module (ModuleLoader format) that registers two cells in the root-scoped shell.overlay slot:
  • the core banner (top): update / up-to-date / failure states for the main program (立即更新 / 重新检查 / 知道了; 不再提示 persists suppression),
