Use when modifying src/core/gemini.ts, adding new API calls, or auditing Gemini integration quality.\nuser-invocable: true\ndisable-model-invocation: false\npaths:\n  - src/core/gemini.ts\n  - src/core/fileSearch.ts\n  - src/core/tools.ts\n---\n\n# Gemini API Best Practices\n\nWhen reviewing or modifying Gemini API integration code, ensure compliance with Google's official best practices from `google-gemini/gemini-skills`.\n\n## SDK and Package\n\n- **Correct SDK**: `@google/genai` (npm)\n- **NEVER use deprecated**: `@google/generative-ai` (old package)\n- Prefer environment variables for API keys over hard-coding\n\n## Safety Settings\n\nAll API calls (`generateContent`, `generateContentStream`, `chats.create`) MUST include `safetySettings` in the config:\n\n```typescript\nimport { HarmCategory, HarmBlockThreshold, type SafetySetting } from \"@google/genai\";\n\nconst DEFAULT_SAFETY_SETTINGS: SafetySetting[] = [\n  { category: HarmCategory.HARM_CATEGORY_HARASSMENT, threshold: HarmBlockThreshold.BLOCK_MEDIUM_AND_ABOVE },\n  { category: HarmCategory.HARM_CATEGORY_HATE_SPEECH, threshold: HarmBlockThreshold.BLOCK_MEDIUM_AND_ABOVE },\n  { category: HarmCategory.HARM_CATEGORY_SEXUALLY_EXPLICIT, threshold: HarmBlockThreshold.BLOCK_MEDIUM_AND_ABOVE },\n  { category: HarmCategory.HARM_CATEGORY_DANGEROUS_CONTENT, threshold: HarmBlockThreshold.BLOCK_MEDIUM_AND_ABOVE },\n];\n```\n\n## Response Validation (finishReason)\n\nAlways check `finishReason` on response candidates:\n\n- `SAFETY` - Response blocked by safety filters; inform user to rephrase\n- `RECITATION` - Blocked due to potential copyrighted content recitation\n- `MAX_TOKENS` - Output truncated; consider informing user\n- `STOP` - Normal completion\n\n```typescript\nimport { FinishReason } from \"@google/genai\";\n\n// Check candidates[0].finishReason after each response\nif (candidate.finishReason === FinishReason.SAFETY) {\n  // Handle blocked response\n}\n```\n\nFor non-streaming: check `response.candidates[0].finishReason` before using `response.text`.\nFor streaming: check `finishReason` in chunk candidates.\n\n## System Instructions\n\n- Pass via `systemInstruction` in config (not as a chat message)\n- System instructions are interaction-scoped; re-specify on each chat session creation\n\n## Tool / Function Calling\n\n- Pass tools via `config.tools` array\n- Use proper SDK types (`Tool`, `FunctionDeclaration`) without forced `as` casts\n- `googleSearch` and `fileSearch` are first-class `Tool` properties\n- `fileSearch` CANNOT be combined with `functionDeclarations` in the same request\n- `googleSearch` CANNOT be combined with `functionDeclarations`\n\n## Streaming\n\n- Use `generateContentStream` or `chat.sendMessageStream` for streaming\n- Use SDK Chat (`ai.chats.create()`) for automatic thought signature handling\n- Process ALL parts in each chunk (text, thought, functionCall can coexist)\n\n## Thinking / Reasoning\n\n- Thinking is ON by default for Gemini 2.5+ and 3.x models\n- `thinkingBudget: 0` disables thinking (except models that require it)\n- Gemini 3.1 Flash Lite uses `thinkingLevel` instead of `thinkingBudget`\n- Gemini 3 Pro / 3.1 Pro require thinking (cannot be disabled)\n- Access thought parts via `part.thought` boolean on content parts\n\n## Model Names\n\nCurrent models (use these):\n- `gemini-3.1-pro-preview` - Flagship, 1M context\n- `gemini-3-flash-preview` - Fast, balanced\n- `gemini-3.1-flash-lite-preview` - Cost-efficient\n- `gemini-2.5-pro` / `gemini-2.5-flash` - Still available\n\nDeprecated models (NEVER use):\n- All `gemini-2.0-*`, `gemini-1.5-*`, `gemini-1.0-*`, `gemini-pro`\n\n## Type Safety\n\n- Use proper SDK types from `@google/genai` instead of `as` casts\n- `Tool` interface supports `googleSearch`, `fileSearch`, `functionDeclarations`, `codeExecution`, `urlContext`\n- Import enums (`FinishReason`, `HarmCategory`, `HarmBlockThreshold`) as values, not just types\n\n## Checklist for New API Calls\n\n- [ ] `safetySettings: DEFAULT_SAFETY_SETTINGS` included in config\n- [ ] `finishReason` checked on response candidates\n- [ ] `systemInstruction` passed in config (not as message)\n- [ ] No forced `as Tool` type assertions\n- [ ] Proper error handling with `formatError()`\n- [ ] Usage metadata extracted for cost tracking\n","tagline":"Review and fix Gemini API usage against Google's official best practices.
