The Settings dialog now supports replacing the OpenCode config directory directly from the UI. A new drop-zone component stages an uploaded folder client-side and posts it to POST /api/settings/opencode-config-directory/replace, which installs the upload atomically: files are written to a staging directory, the current config directory is backed up and swapped in, node_modules is preserved across the swap, and executables (shebang files) get their permissions restored. The upload must contain opencode.json or opencode.jsonc at its root, which is canonicalized to opencode.json and registered as the default config. Staging and rollback leave the previous config directory intact if any step fails.

Upload-path policy now lives in one shared module (shared/utils/opencode-config-upload.ts) used by both the frontend staging and the backend service — node_modules, .git, and .DS_Store are excluded. The existing Skills/Commands directory-upload flows were consolidated onto a shared directoryUpload helper, and the File Browser dropped its duplicated collection handling. After a successful replace, a sticky restart-required notice prompts the user to restart OpenCode for the changes to take effect.

📝 Walkthrough

Walkthrough

The PR adds global OpenCode configuration-directory replacement. It introduces shared directory-upload handling, backend validation and atomic replacement, configured-path persistence, frontend upload controls, and pending-restart management.

Changes

OpenCode upload and replacement

Layer / File(s) Summary
Shared directory upload contracts
shared/src/utils/*, frontend/src/lib/directoryUpload.ts, frontend/src/api/settings.ts, frontend/src/components/file-browser/*, frontend/src/components/settings/SkillInstallDialog.tsx, frontend/src/components/settings/UploadFolderButton.tsx
Directory uploads now preserve relative paths through shared browser utilities and multipart API payloads. Skill, file-browser, and OpenCode uploads use DirectoryUploadItem.
Backend configuration replacement
backend/src/routes/settings.ts, backend/src/services/opencode-config-directory.ts, backend/test/routes/settings-config-directory-replace.test.ts, backend/test/services/opencode-config-directory.test.ts, backend/test/services/upload-paths.test.ts
The backend validates manifests and configuration files, stages uploads, preserves selected entries, atomically replaces the configuration directory, restores executable permissions, and reports operation results.
Configuration paths and default persistence
backend/src/index.ts, backend/src/services/opencode-directory-files.ts, backend/src/services/opencode-import.ts, backend/src/services/settings.ts, backend/src/services/skills.ts, backend/test/services/*
OpenCode files and skills now use getConfigPath(). Imports and workspace synchronization use upsertDefaultOpenCodeConfig, which updates or creates the default configuration.
Configuration replacement interface
frontend/src/components/settings/OpenCodeConfigDirectoryUpload.tsx, frontend/src/components/settings/OpenCodeConfigManager.tsx, frontend/src/components/settings/OpenCodeConfigDirectoryUpload.test.tsx
The settings UI supports folder selection and drag-and-drop, filters excluded paths, validates limits and root configuration files, confirms replacement, and displays result details.
Pending restart workflow
frontend/src/components/settings/OpenCodeRestartPendingNotice.tsx, frontend/src/hooks/useOpenCodeServerActions.ts, frontend/src/components/settings/SettingsDialog.tsx, frontend/src/components/settings/*test.tsx
Pending restart state moved to a dedicated notice in the OpenCode settings tab. The notice probes active sessions, supports “Later”, and confirms server restarts.

Estimated code review effort: 4 (Complex) | ~60 minutes

Merge Risk: 🟡 Moderate · up to b1bcc

The new replacement flow can persist the uploaded default configuration before the filesystem swap completes, so a failed upload may leave stored and on-disk configuration inconsistent; the browser fallback can also bypass configured file exclusions. These concrete correctness issues should be fixed before merge.

Move the file-count limit into the shared package.

MAX_CONFIG_DIRECTORY_FILES is declared here with the literal 5000. The backend declares the same limit in backend/src/services/opencode-config-directory.ts. If one side changes, the client-side message and the server rejection disagree. Export the limit from @opencode-manager/shared and import it in both places.

Persist the default config after the directory swap succeeds, or restore it on failure.

Line 92 writes the uploaded config into the database before any filesystem work starts. If staging, fs.rename, or chmod fails at lines 108-139, the catch block at lines 155-167 restores the previous directory from the backup but leaves the database default config pointing at the uploaded content. The route then returns 500, so the caller assumes nothing changed, while the persisted default config and the on-disk opencode.json disagree. A later restart or config read then uses the wrong content.

Move the upsert after the swap, or capture the previous default config and restore it in the catch block.

🛠️ Proposed ordering fix
-  new SettingsService(db).upsertDefaultOpenCodeConfig(chosenConfig.file.content.toString('utf8'), userId)
-
   const filesToWrite = kept
     if (backupPath) {
       await fs.rm(backupPath, { recursive: true, force: true })
     }
 
+    new SettingsService(db).upsertDefaultOpenCodeConfig(chosenConfig.file.content.toString('utf8'), userId)
+
     logger.info(`Replaced OpenCode config directory at ${configDirectory}`)

Note: validation errors raised by upsertDefaultOpenCodeConfig would then surface after the swap. If pre-swap validation must stay, keep a validation-only call first and persist only after the swap.

Move the replacement response contract to @opencode-manager/shared. The new HTTP response contract is frontend-local, so the frontend and backend can drift.

  • frontend/src/api/types/settings.ts#L151-L159: define the replacement response as a shared Zod schema and inferred type.
  • frontend/src/api/settings.ts#L17-L21: import the shared replacement response type instead of the frontend-local interface.

As per coding guidelines, “Keep shared types and Zod schemas in shared/src/.”

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Apply shouldSkip in the fallback branch.

When webkitGetAsEntry() is unavailable, this branch ignores options.shouldSkip. A caller that excludes files such as .DS_Store will upload them through the fallback path. Filter each fallback file before adding it to items.

Proposed fix
     for (let i = 0; i < dataTransfer.files.length; i++) {
       const file = dataTransfer.files[i]
-      items.push({ file, relativePath: file.name })
+      if (!shouldSkip?.(file.name, false)) {
+        items.push({ file, relativePath: file.name })
+      }
