DeepSeek Pre-edit Review — VS Code extension

The VS Code client of DeepSeek Pre-edit Review. It connects to the DSH Host plugin over a Unix domain socket, opens one editable vscode.diff per proposed file change, and only sends a decision back to the Host after the user clicks Accept (or types the accept keybinding). The Host is the only component that writes to the workspace; the extension never commits anything itself.

How it works

• The right side of the diff is a dpr: document backed by an in-memory FileSystemProvider registered without isReadonly, so it is editable.
• dpr.accept sends the document text (document.getText(), including unsaved edits) as finalContent, then saves the document (clears the dirty state so closing the diff never shows a save prompt) and closes the tab.
• dpr.reject asks for an optional reason, reverts the proposal document, closes the tab, and sends a reject decision.
• New files are shown against an empty dpr: original, so the left side always renders even though the file does not exist yet.
• Connection: hello with the token from <stateDir>/token; automatic 3 s backoff reconnect; one warning when the connection goes offline.
• dpr.acceptAll (only with dpr.autoAccept enabled) arms a 5-minute auto-accept window and shows an AUTO-ACCEPT status bar item.

Review queue and history (0.2.0)

The extension contributes an activity-bar container (dpr, shield-with-check icon in media/icon.svg) with two tree views:

• Pending Reviews (dpr.pendingView) — one row per pending request from the live queue (displayPath, mode · toolName, full path/opened-at/operation in the tooltip). Clicking a row opens that review's editable diff and repeats the decision hint. ✓ / ✗ inline actions decide one row; view-title actions arm Accept All and reject every pending review. The container shows a badge with the pending count while connected.
• Review History (dpr.historyView) — the last 50 settled decisions, newest first, persisted in context.workspaceState under dpr.history as {requestId, displayPath, toolName, mode, status, outcome, edited, at}. Statuses: committed | rejected | conflict | expired | cancelled | failed. "Clear History" asks for modal confirmation first.

Both views refresh on every queue change and every settled decision; corrupt or older history values are ignored rather than failing the view.

Self-test

dpr.runSelfTest starts a mock Host on a temporary Unix socket, writes a real token file, connects the real IPC client/ReviewSession, and runs three scenarios:

1. accept-with-edit — the mock sends review/request; the test applies a WorkspaceEdit to the proposed document and calls dpr.accept; the mock asserts the decision's finalContent contains the edit marker.
2. reject (new file) — the mock sends a request for a non-existent file (the left side is the empty dpr: original); the test calls dpr.reject and the mock asserts status === 'reject' and that no workspace file was created.
3. reject-all — a third request is opened, the real dpr.rejectAll command drains it, and the test asserts the pending tree provider went empty.

It also instantiates both tree providers against the running session, appends a synthetic record through the real ReviewHistoryStore (then removes it), and exercises dpr.rejectAll. A JSON report {ok, vscodeVersion, steps, error?} is written to <workspace>/.spike/ext-selftest.json. The test also runs automatically ~2 s after activation when <workspace>/.spike exists.

Build

node build.mjs
../../node_modules/.bin/vsce package --no-dependencies --allow-missing-repository

Install the produced VSIX with code --install-extension deepseek-pre-edit-review-0.2.0.vsix.

Review pause (暂停审批)

When the Host reports /review off active for a session, the status bar appends · 已关闭 / · OFF and the tooltip explains that writes are not reviewed. The extension only reflects Host state; it cannot enable or disable pause.
