 /**
- * Gemini CLI E2E tests — verify skills work when invoked by Gemini CLI.
+ * Gemini CLI E2E smoke test — verify Gemini CLI can start and discover skills.
  *
- * Spawns `gemini -p` with stream-json output in the repo root (where
- * .agents/skills/ already exists), parses JSONL events, and validates
- * structured results. Follows the same pattern as codex-e2e.test.ts.
+ * This is a lightweight smoke test, not a full integration test. Gemini CLI
+ * gets lost in worktrees and times out on complex tasks. The smoke test
+ * validates that the skill files are structured correctly for Gemini's
+ * .agents/skills/ discovery mechanism.
  *
  * Prerequisites:
  * - `gemini` binary installed (npm install -g @google/gemini-cli)
