Comment:
**`mode` field missing from `CcRelayConfig` fixture**

`CcRelayConfig` declares `mode: CcRelayMode` as a required field, but `baseConfig` omits it. This is a TypeScript type error that will be caught by `pnpm tsgo`. All tests in this file pass the partial object to `createDispatcher`, so every test silently uses `undefined` for `mode`.

```suggestion
  const baseConfig: CcRelayConfig = {
    mode: "hybrid",
    claudeBin: "claude",
    workdir: "/tmp/test-workspace",
    runAsUser: "",
    permissionMode: "default",
    model: "claude-opus-4-6",
    timeoutSeconds: 60,
    progressIntervalSeconds: 0, // Disable progress for tests
    maxResultChars: 4000,
    maxAttachments: 10,
    maxAttachmentBytes: 10 * 1024 * 1024,
  };
```

**`skipAfterCompaction` is never reset — final results lost after mid-task compaction**

Once `skipAfterCompaction` is set to `true`, every subsequent `assistant` entry in the rest of the loop is skipped — including the actual final result that Claude produces after the compaction event finishes. For any long-running task that triggers context compaction mid-execution, `extractFinalResult` will return only the pre-compaction text, or an empty string if compaction happens early.

The existing test only covers the case where the compaction summary is the very last entry. It does not exercise the case where real results follow the compaction event, so this path goes undetected.

The safest fix is to only suppress the single `assistant` message that immediately follows the large user-context block (the "compaction summary"), then allow subsequent entries through again:

```ts
let skipNextAssistant = false;

for (let i = promptIdx; i < entries.length; i++) {
  const entry = entries[i]!;
  if (entry.type === "user") {
    const content = entry.message?.content;
    if (Array.isArray(content) && content.length >= 50) {
      skipNextAssistant = true;
    }
  } else if (entry.type === "assistant") {
    if (skipNextAssistant) {
      skipNextAssistant = false;
      continue;
    }
    // extract text blocks
  }
}
```

Comment:
**`--permission-mode default` always injected even when using default settings**

`buildClaudeArgs` gates the flag on `job.permissionMode || cfg.permissionMode`. However, `job.permissionMode` is set from `cfg.permissionMode` in the dispatcher (which defaults to `"default"`), so the condition is always truthy with the default configuration. This means `--permission-mode default` is passed to every Claude CLI invocation.

If the Claude CLI does not accept `"default"` as a valid value for `--permission-mode`, every invocation with the out-of-the-box configuration will fail. Consider only passing the flag when the value is a non-default override:

```suggestion
  if ((job.permissionMode || cfg.permissionMode) && (job.permissionMode || cfg.permissionMode) !== "default") {
    args.push("--permission-mode", job.permissionMode || cfg.permissionMode);
  }
```

**Temp file not cleaned up when `sendFile` throws**

The `try` block covers `writeFileSync`, `sendFile`, and `unlinkSync` together. If `sendFile` rejects, `unlinkSync` is never reached and the temporary `.cc-relay-output-*.md` file is left in `job.workdir` permanently. On subsequent runs the workspace snapshot will detect it as a "new file" and attempt to send it as an attachment.

Split the cleanup into a `finally` block so the file is always removed:

```ts
const tmpPath = path.join(job.workdir, `.cc-relay-output-${job.id.slice(0, 8)}.md`);
try {
  fs.writeFileSync(tmpPath, result.resultText, "utf-8");
  await this.callbacks.sendFile(job.channel, job.target, tmpPath, "full-output.md");
} catch {
  /* best-effort */
} finally {
  try { fs.unlinkSync(tmpPath); } catch { /* ignore */ }
}
```

**`@sinclair/typebox` runtime dependency not declared in extension `package.json`**

`cc-dispatch-tool.ts` imports `{ Type }` from `@sinclair/typebox` at runtime, but the extension's `package.json` has no `dependencies` section. The repo guidelines require runtime deps to live in the extension's own `dependencies` so that `npm install --omit=dev` in the plugin dir succeeds.

It works today only because `@sinclair/typebox` is hoisted from the root workspace, but that is fragile — a future root version bump or deduplication could break the plugin for standalone installs.

Add a `dependencies` field:
```json
"dependencies": {
  "@sinclair/typebox": "0.34.49"
}
```
