quality |\n\n## Use Case Recommendations\n\n### 🏆 Production Deployment (Recommended)\n\n**Use**: `transformers-local-onnx.ts`\n\n**Why**:\n- Predictable performance (no network variance)\n- No API costs\n- No rate limits\n- Works offline\n- Fast after initial load\n\n**Best for**:\n- Deno Deploy\n- Render / Railway / Fly.io\n- Docker containers\n- Any environment with file system access\n\n### 🚀 Quick Start / Prototyping\n\n**Use**: `transformers-cosine.ts`\n\n**Why**:\n- Zero setup (auto-downloads model)\n- No API keys needed\n- Good performance after first run\n- Easy to switch to local later\n\n**Best for**:\n- Development\n- Testing\n- Quick demos\n- When you don't want to download models manually\n\n### ☁️ Cloudflare Workers\n\n**Use**: `cloudflare-bge-cosine.ts`\n\n**Why**:\n- Workers have 1MB code size limit (can't fit local models)\n- Cloudflare AI is optimized for Workers\n- Free tier is generous\n- Low latency\n\n**Best for**:\n- Cloudflare Workers/Pages\n- Edge deployment\n- Global low-latency requirements\n\n### 🎯 Maximum Accuracy\n\n**Use**: `hf-inference-qwen3-cosine.ts` or `mixedbread-embeddings-cosine.ts`\n\n**Why**:\n- Higher MTEB scores\n- Better semantic understanding\n- More dimensions (768-1024 vs 384)\n\n**Best for**:\n- When accuracy matters more than speed\n- Complex semantic queries\n- Production with budget for API calls\n\n### 📦 Managed Solution\n\n**Use**: `mixedbread.ts` or `jigsawstack-orama.ts`\n\n**Why**:\n- No embedding management needed\n- Handles storage, search, and embeddings\n- Less code to maintain\n\n**Best for**:\n- When you want a managed solution\n- Don't want to store embeddings yourself\n- Prefer APIs over local computation\n\n## Migration Path\n\n### From API-based to Local\n\n1. Download the model:\n ```bash\n cd search/models\n ./download-model.sh\n ```\n\n2. Update `search/index.ts`:\n ```typescript\n // Before\n // import { searchStrategy, generateEmbeddings } from \"./openai-cosine.ts\";\n \n // After\n import { searchStrategy, generateEmbeddings } from \"./transformers-local-onnx.ts\";\n ```\n\n3. Recalculate embeddings (if dimensions differ):\n ```bash\n GET /cache/recalculate?force=true\n ```\n\n### From transformers-cosine to transformers-local-onnx\n\n1. Download the model (same as above)\n2. Update the import\n3. No recalculation needed (same model, same dimensions)\n\n## Environment-Specific Notes\n\n### Val.town\n- **Recommended**: `transformers-cosine.ts` (isolate has caching)\n- **Alternative**: Any API-based strategy\n- **Avoid**: `transformers-local-onnx.ts` (no persistent file system)\n\n### Deno Deploy\n- **Recommended**: `transformers-local-onnx.ts` (with deployment package)\n- **Alternative**: `transformers-cosine.ts` or API-based\n- **Note**: Include model files in deployment\n\n### Docker\n- **Recommended**: `transformers-local-onnx.ts`\n- **Note**: Include model files in image\n- **Example**:\n ```dockerfile\n COPY search/models/all-MiniLM-L6-v2 /app/search/models/all-MiniLM-L6-v2\n ```\n\n### Serverless (AWS Lambda, Google Cloud Functions)\n- **Recommended**: API-based strategies (less cold start time)\n- **Alternative**: `transformers-local-onnx.ts` (if you can handle cold starts)\n- **Note**: Local models increase deployment package size\n\n### Local Development\n- **Recommended**: `transformers-cosine.ts` (auto-download)\n- **Alternative**: `transformers-local-onnx.ts` (if downloaded)\n- **Note**: Both work great for development\n\n## Benchmarking Your Setup\n\nRun the test harness to compare strategies on your infrastructure:\n\n```bash\ncd testing\ndeno run --allow-read --allow-env --allow-net test-search.ts\n```\n\nThis will show actual performance numbers for your specific setup.\n\n## Summary Table\n\n| Criteria | Best Choice |\n|----------|-------------|\n| **Fastest** | transformers-local-onnx |\n| **Easiest Setup** | transformers-cosine |\n| **Most Accurate** | hf-inference-qwen3 |\n| **Cheapest** | transformers-local-onnx (free) |\n| **Best for Production** | transformers-local-onnx |\n| **Best for Cloudflare** | cloudflare-bge-cosine |\n| **Best for Val.town** | transformers-cosine |\n| **Most Reliable** | openai-cosine |\n| **Fully Managed** | mixedbread or jigsawstack |\n\n## Still Unsure?\n\nDefault recommendation: **transformers-local-onnx.ts**\n\nIt offers the best combination of speed, cost (free), and reliability for most production use cases. The only downside is the initial setup (downloading model files), which takes a few minutes.\n\nIf you can't download models or need to deploy immediately, use **transformers-cosine.ts** as it auto-downloads on first run.\n\n","createdAt",["D",1762293982370],"branchVersion","branchId","632d0edc-2793-11f0-9d52-569c3dd06744","id","632cc576-2793-11f0-9d52-569c3dd06744","groq-docs",["D",1746217442601],"deletedAt","legacyEnvVars",true,"privacy","public","httpPrivacy","description","imageUrl","a8270e74-6479-475a-8025-9b69544ee0e7","pinnedFileId","632eed24-2793-11f0-9d52-569c3dd06744","pinPreview","pinMigrated","screenshotVersion","likeCount",0,"orgId","8319defa-6e1a-46d4-ba66-2114ffd3360b","tursoName","tursoHostname","tursoMeasuredAt","pinned","userPerm","r","valPerm","blobPerm","rw","emailPerm","sqlitePerm","projectPerm","telemetryPerm","user",{"_94":93,"_101":97},"org",{"_94":93,"_95":-5,"_96":97,"_18":53,"_98":99,"_100":24},"branch",{"_13":83,"_31":84,"_41":40,"_85":42,"_86":-5,"_87":-5,"_88":-5,"_89":-5,"_90":-5,"_91":43,"_92":93},"isOwned",105,"main","projectId","forkedBranchId","forkedBranchVersion","forkedProjectPrivacy","forkedProjectId","forkedProjectOrgId","projectName","userHandle","yawnxyz","handle","displayName","avatar","https://images.clerk.dev/oauth_github/img_2NnaHhpxNuH1xWRIRjQNoo16TVc.jpeg","tier","pro","canRestrictVals","profileImageUrl","branchName","","adoptOrgId",{"_41":42,"_31":43,"_36":538,"_45":-5,"_46":47,"_48":49,"_50":49,"_51":-5,"_52":-5,"_18":53,"_54":55,"_56":47,"_57":-5,"_58":-5,"_59":60,"_61":62,"_63":-5,"_64":-5,"_65":-5,"_66":-5,"_67":68,"_69":68,"_70":71,"_72":71,"_73":71,"_74":68,"_75":68,"_76":539,"_78":540,"_80":541,"_82":24},"tree",[250,259,260,275,280,282,283,284,285,286,287,288,289,290],"files",[250,251,252,253,254,255,256,257,258,259,260,261,262,263,264,265,266,267,268,269,270,271,272,273,274,275,276,277,278,279,280,281,282,283,284,285,286,287,288,289,290],"counts",{"_240":60,"_241":161,"_242":60,"_243":244,"_245":246},"contents",[124,125,126,127,128,129,130,131,132,133,134,135,136,137],"upstreamProject","upstreamBranch","emptyEnvVars","flags",[],"hasHttpFiles","grants","orgs","customDomains",{},{"_41":234,"_31":235,"_29":236,"_141":-5,"_39":40,"_38":237,"_143":47,"_36":238,"_13":60,"_33":214,"_34":-5,"_23":24,"_147":-5,"_26":239},{"_41":228,"_31":229,"_29":230,"_141":-5,"_39":40,"_38":231,"_143":47,"_36":232,"_13":60,"_33":214,"_34":-5,"_23":24,"_147":-5,"_26":233},{"_41":222,"_31":223,"_29":224,"_141":-5,"_39":40,"_38":225,"_143":47,"_36":226,"_13":60,"_33":214,"_34":-5,"_23":24,"_147":-5,"_26":227},{"_41":216,"_31":217,"_29":218,"_141":-5,"_39":40,"_38":219,"_143":47,"_36":220,"_13":60,"_33":214,"_34":-5,"_23":24,"_147":-5,"_26":221},{"_41":209,"_31":210,"_29":211,"_141":-5,"_39":40,"_38":212,"_143":47,"_36":213,"_13":60,"_33":214,"_34":-5,"_23":24,"_147":-5,"_26":215},{"_41":202,"_31":203,"_29":204,"_141":-5,"_39":40,"_38":205,"_143":24,"_36":206,"_13":60,"_33":20,"_34":207,"_23":24,"_147":-5,"_26":208},{"_41":195,"_31":196,"_29":197,"_141":-5,"_39":40,"_38":198,"_143":47,"_36":199,"_13":60,"_33":20,"_34":200,"_23":24,"_147":-5,"_26":201},{"_41":188,"_31":189,"_29":190,"_141":-5,"_39":40,"_38":191,"_143":24,"_36":192,"_13":185,"_33":20,"_34":193,"_23":24,"_147":-5,"_26":194},{"_41":180,"_31":181,"_29":182,"_141":-5,"_39":40,"_38":183,"_143":24,"_36":184,"_13":185,"_33":20,"_34":186,"_23":24,"_147":-5,"_26":187},{"_41":173,"_31":174,"_29":175,"_141":-5,"_39":40,"_38":176,"_143":47,"_36":177,"_13":60,"_33":145,"_34":178,"_23":24,"_147":-5,"_26":179},{"_41":164,"_31":165,"_29":55,"_141":-5,"_39":40,"_38":166,"_143":24,"_36":167,"_13":168,"_33":169,"_34":170,"_23":24,"_147":171,"_26":172},{"_41":156,"_31":157,"_29":158,"_141":-5,"_39":40,"_38":159,"_143":24,"_36":160,"_13":161,"_33":20,"_34":162,"_23":24,"_147":-5,"_26":163},{"_41":149,"_31":150,"_29":151,"_141":-5,"_39":40,"_38":152,"_143":24,"_36":153,"_13":60,"_33":145,"_34":154,"_23":24,"_147":-5,"_26":155},{"_41":138,"_31":139,"_29":140,"_141":-5,"_39":40,"_38":142,"_143":47,"_36":144,"_13":60,"_33":145,"_34":146,"_23":24,"_147":-5,"_26":148},"93344376-b8f1-11f0-ab7b-0224a6c84d84","utils.ts","93344448-b8f1-11f0-ab7b-0224a6c84d84","parentId",24,"latest",["D",1762200814128],"script","import

Initial Cache Population\n\nOn first run, the cache will be empty. You should populate it by running:\n\n```bash\nGET /cache/recalculate\n```\n\nThis will:\n- Fetch all pages from the URLs list\n- Calculate token counts for each page\n- Generate AI metadata (categories, tags, use cases, questions)\n- Generate embeddings for each page\n- Calculate content hashes for change detection\n- Store everything in the SQLite cache\n- Return a summary of what was cached\n\n**Important**: This will take some time as it processes all pages, generates metadata, and calculates tokens for each. Be patient!\n\n**Note**: On subsequent runs, unchanged pages (detected by content hash) will be automatically skipped unless you use force mode.\n\n### 2. Verify Cache\n\nCheck that the cache was populated:\n\n```bash\nGET /cache/stats\n```\n\nThis returns:\n```json\n{\n \"cachedPages\": 121,\n \"totalTokens\": 1234567\n}\n```\n\n## When to Recalculate\n\nYou should run `/cache/recalculate` in these scenarios:\n\n### ✅ Required Recalculations\n\n1. **First time setup** - Cache is empty\n2. **URL list changes** - You've added or removed URLs from the `urls` array\n3. **Content updates** - Documentation pages have been updated and you want fresh data\n4. **Token count needed** - You need accurate token counts for new content\n5. **Metadata refresh** - You want to regenerate AI metadata or embeddings\n\n### 🔄 Default Mode (Smart Recalculation)\n\nBy default, `/cache/recalculate` uses hash-based change detection:\n\n```bash\nGET /cache/recalculate\n```\n\n**Behavior:**\n- Fetches each page and calculates its content hash (SHA-256)\n- Compares hash with cached version\n- **Skips pages with unchanged content** (saves time and API calls)\n- Only processes pages that have changed\n- Still generates embeddings and metadata for changed pages\n\n**Response includes:**\n- `processed` - Number of pages actually processed\n- `skipped` - Number of pages skipped (unchanged)\n- `force` - Always `false` in default mode\n\n### ⚡ Force Mode (Recalculate Everything)\n\nTo force recalculation of all pages (ignoring hash checks):\n\n```bash\nGET /cache/recalculate?force=true\n```\n\n**Use cases:**\n- Regenerating all metadata/embeddings even if content unchanged\n- After updating metadata generation prompts\n- When you want to ensure everything is fresh\n\n### ⚠️ Partial Updates\n\nFor single page updates, you can use:\n\n```bash\nGET /cache/clear/:path\n```\n\nThis clears the cache for a specific page. The next time that page is requested via `/page/:path`, it will be fetched fresh and recached.\n\n### 🔄 Routine Maintenance\n\n- **Weekly**: Run recalculate (default mode) to catch any documentation updates efficiently\n- **After major docs changes**: Use force mode to regenerate everything\n- **When adding new pages**: Update the `urls` array, then run recalculate\n\n## API Endpoints\n\n### Page Endpoints\n\n#### `GET /page/docs`\nGet the root docs page (cached if available).\n\n#### `GET /page/:path`\nGet a specific page by path. Examples:\n- `/page/api-reference`\n- `/page/agentic-tooling/compound-beta`\n- `/page/model/llama-3.1-8b-instant`\n\n**Response includes:**\n- `url` - The source URL\n- `content` - Full page content with frontmatter\n- `charCount` - Character count\n- `tokenCount` - Token count (calculated with tiktoken)\n- All frontmatter fields flattened (title, description, image, etc.)\n\n**Caching**: Responses are cached. First request fetches and caches, subsequent requests are instant.\n\n#### `GET /list`\nGet a list of all available page paths.\n\n**Response:**\n```json\n[\n \"docs\",\n \"agentic-tooling\",\n \"api-reference\",\n ...\n]\n```\n\n#### `GET /search`\nSearch pages by query string.\n\n**Query Parameters:**\n- `q` (required) - Search query string\n- `limit` (optional) - Maximum number of results (default: 10)\n- `minScore` (optional) - Minimum score threshold (default: 0)\n\n**Example:**\n```bash\nGET /search?q=authentication&limit=5\n```\n\n**Response:**\n```json\n{\n \"query\": \"authentication\",\n \"results\": [\n {\n \"path\": \"api-reference\",\n \"url\": \"https://console.groq.com/docs/api-reference.md\",\n \"title\": \"API Reference\",\n \"score\": 45,\n \"snippet\": \"...authentication tokens are required for all API requests...\"\n },\n {\n \"path\": \"quickstart\",\n \"url\": \"https://console.groq.com/docs/quickstart.md\",\n \"title\": \"Quick Start\",\n \"score\": 32,\n \"snippet\": \"...get your API key for authentication...\"\n }\n ],\n \"totalResults\": 2,\n \"totalPages\": 121\n}\n```\n\n**Search Features:**\n- Keyword matching in titles and content\n- Metadata boost (tags, categories, use cases)\n- Score-based ranking\n- Content snippets around matches\n- Uses cached pages when available for faster results\n\n**Note**: Currently uses keyword-based search. Future versions will use embeddings for semantic search.\n\n#### `GET /data`\nGet metadata for all pages (does not use cache - fetches fresh).\n\n**Response:**\n```json\n{\n \"pages\": [\n {\n \"url\": \"...\",\n \"charCount\": 1234,\n \"frontmatter\": {...}\n }\n ],\n \"contents\": [...],\n \"totalPages\": 121,\n \"totalChars\": 1234567\n}\n```\n\n### Cache Management Endpoints\n\n#### `GET /cache/stats`\nGet cache statistics.\n\n**Response:**\n```json\n{\n \"cachedPages\": 121,\n \"totalTokens\": 1234567\n}\n```\n\n#### `GET /cache/clear`\nClear the entire cache.\n\n**Response:**\n```json\n{\n \"message\": \"Cache cleared\",\n \"success\": true\n}\n```\n\n#### `GET /cache/clear/:path`\nClear cache for a specific page.\n\n**Example:**\n```bash\nGET /cache/clear/api-reference\n```\n\n**Response:**\n```json\n{\n \"message\": \"Cache cleared for api-reference\",\n \"success\": true\n}\n```\n\n#### `GET /cache/recalculate`\nRecalculate pages with AI metadata and embeddings generation.\n\n**Query Parameters:**\n- `force` (optional): Set to `true` to force recalculation of all pages, ignoring hash checks\n\n**Default Mode** (no query params):\n```bash\nGET /cache/recalculate\n```\n\n**Force Mode**:\n```bash\nGET /cache/recalculate?force=true\n```\n\n**Response** (Default Mode):\n```json\n{\n \"message\": \"Recalculated 5 pages, skipped 116 unchanged pages\",\n \"results\": [\n {\n \"path\": \"api-reference\",\n \"url\": \"https://console.groq.com/docs/api-reference.md\",\n \"charCount\": 1234,\n \"tokenCount\": 567,\n \"title\": \"API Reference\",\n \"metadata\": {\n \"categories\": [\"API\", \"Reference\"],\n \"tags\": [\"api\", \"endpoints\", \"rest\"],\n \"useCases\": [\"Integrating with Groq API\"],\n \"questions\": [\"How do I authenticate?\", \"What endpoints are available?\"]\n }\n },\n {\n \"path\": \"docs\",\n \"skipped\": true,\n \"reason\": \"Content unchanged (hash matches)\"\n }\n ],\n \"totalPages\": 121,\n \"processed\": 5,\n \"skipped\": 116,\n \"withMetadata\": 5,\n \"withoutMetadata\": 0,\n \"cached\": true,\n \"force\": false\n}\n```\n\n**Response** (Force Mode):\n```json\n{\n \"message\": \"Recalculated 121 pages with AI metadata (force mode)\",\n \"results\": [...],\n \"totalPages\": 121,\n \"processed\": 121,\n \"skipped\": 0,\n \"force\": true\n}\n```\n\n**What it does:**\n- Fetches all pages (or skips unchanged ones in default mode)\n- Calculates token counts\n- Generates AI metadata (categories, tags, use cases, questions)\n- Generates embeddings (currently fake, ready for Groq API)\n- Calculates content hashes for change detection\n- Stores everything in cache\n\n**Important**: This can take several minutes depending on:\n- Number of pages to process (skipped pages are fast)\n- Network speed\n- Token calculation time\n- AI metadata generation time (uses Groq API)\n\n## Cache Behavior\n\n### How Caching Works\n\n1. **First Request**: \n - Check cache → Not found\n - Fetch from URL\n - Calculate tokens\n - Store in cache\n - Return data\n\n2. **Subsequent Requests**:\n - Check cache → Found\n - Return cached data immediately\n\n### Cache Storage\n\nCache is stored in SQLite with the following schema:\n\n```sql\nCREATE TABLE groq_docs_cache_v3 (\n url TEXT PRIMARY KEY,\n content TEXT NOT NULL,\n charCount INTEGER NOT NULL,\n tokenCount INTEGER,\n frontmatter TEXT NOT NULL,\n metadata TEXT,\n contentHash TEXT,\n embeddings TEXT,\n cachedAt INTEGER NOT NULL\n)\n```\n\n**Fields:**\n- `url` - Source URL (primary key)\n- `content` - Full page content with frontmatter\n- `charCount` - Character count\n- `tokenCount` - Token count (calculated with tiktoken)\n- `frontmatter` - Parsed frontmatter (JSON)\n- `metadata` - AI-generated metadata (categories, tags, use cases, questions)\n- `contentHash` - SHA-256 hash of content (for change detection)\n- `embeddings` - Content embeddings vector (JSON array)\n- `cachedAt` - Timestamp when cached\n\n### Cache Invalidation\n\nCache is invalidated when:\n- You manually clear it via `/cache/clear`\n- You recalculate via `/cache/recalculate`\n- Cache is cleared for a specific page via `/cache/clear/:path`\n\n**Note**: Cache does NOT automatically expire. If documentation changes, you must manually recalculate.\n\n## Adding New Pages\n\n1. **Add URL to the `urls` array** in `main.tsx`:\n ```typescript\n const urls = [\n // ... existing URLs\n \"https://console.groq.com/docs/new-page.md\",\n ];\n ```\n\n2. **Run recalculate**:\n ```bash\n POST /cache/recalculate\n ```\n\n3. **Verify**:\n ```bash\n GET /cache/stats\n GET /list # Should include your new page\n ```\n\n## Token Counting\n\nToken counts are calculated using [tiktoken](https://github.com/openai/tiktoken) with the `gpt-4` encoding (cl100k_base). This is the same encoding used by:\n- GPT-4\n- GPT-3.5-turbo\n- Many other OpenAI models\n\nToken counts are:\n- Calculated on first fetch\n- Stored in cache\n- Returned in API responses\n- Expensive to compute (which is why caching is important)\n\n## AI Metadata Generation\n\nEach page can have AI-generated metadata using Groq's chat completions API:\n\n- **Categories**: 2-4 broad categories (e.g., \"API\", \"Authentication\", \"Models\")\n- **Tags**: 5-10 specific tags/keywords\n- **Use Cases**: 2-4 practical use cases or scenarios\n- **Questions**: 5-10 questions users might ask\n\nMetadata is generated during `/cache/recalculate` and stored in the cache.\n\n## Search\n\nThe API includes a search endpoint (`/search`) that allows you to search across all documentation pages.\n\n### Current Implementation (Keyword-Based)\n\nCurrently uses keyword matching:\n- Searches in page titles and content\n- Boosts results matching metadata (tags, categories, use cases)\n- Returns ranked results with relevance scores\n- Includes content snippets around matches\n\n### Future Implementation (Semantic Search)\n\nThe search system is designed to support embeddings-based semantic search:\n- `generateEmbeddings()` - Generates embeddings (currently fake, ready for real API)\n- `vectorSearch()` - Vector similarity search function (ready to use when embeddings are real)\n- Will enable semantic understanding of queries (not just keyword matching)\n\n## Embeddings\n\nContent embeddings are generated for each page. Currently using a fake implementation (deterministic 384-dimensional vectors) that's ready to be replaced with actual embeddings API when available.\n\nEmbeddings are:\n- Generated during recalculation\n- Stored in cache\n- Will be used for semantic search and similarity matching (currently using keyword search)\n\n## Hash-Based Change Detection\n\nContent hashes (SHA-256) are calculated and stored for each page. This enables:\n\n- **Smart recalculation**: Skip unchanged pages automatically\n- **Efficient updates**: Only process pages that have actually changed\n- **Performance**: Significantly faster recalculation when most content is unchanged\n\nHashes are compared during `/cache/recalculate` (default mode) to determine if a page needs reprocessing.\n\n## Troubleshooting\n\n### Cache seems stale\nRun `/cache/recalculate` to refresh everything.\n\n### Page not found\n1. Check `/list` to see if the path exists\n2. Verify the URL is in the `urls` array\n3. Ensure the path matches the URL structure (e.g., `api-reference` for `/docs/api-reference.md`)\n\n### Token counts seem wrong\n1. Clear cache for that page: `POST /cache/clear/:path`\n2. Request the page again: `GET /page/:path`\n3. Or recalculate everything: `POST /cache/recalculate`\n\n### Performance issues\n- Use `/page/:path` endpoints (cached) instead of `/data` (uncached)\n- Check cache stats: `GET /cache/stats`\n- Ensure cache is populated before production use\n\n## Code Structure\n\nThe codebase is organized into modular files:\n\n- **`main.tsx`** - Main Hono app, routes, and URL definitions\n- **`utils.ts`** - Utility functions:\n - Cache management (getFromCache, setCache, clearCache, getCacheStats)\n - Content fetching (getTextFromUrl)\n - Frontmatter parsing (parseFrontmatter, addUrlSourceToFrontmatter)\n - Token counting (calculateTokenCount)\n - Hash calculation (calculateContentHash)\n - Rate limiting for fetches\n- **`groq.ts`** - Groq API functions:\n - Chat completions (groqChatCompletion)\n - Metadata generation (generatePageMetadata)\n- **`search.ts`** - Search and embeddings utilities:\n - Embeddings generation (generateEmbeddings) - fake implementation ready for real API\n - Search functions (searchPages) - keyword-based search (will use embeddings later)\n - Vector similarity search (vectorSearch) - ready for embeddings-based search\n\n## Development\n\n### Local Development\n\n```bash\ndeno run --allow-net --allow-env main.tsx\n```\n\n**Note**: SQLite caching is automatically disabled when running locally (detected via `valtown` environment variable). The app will work without caching, but cache-related endpoints will return appropriate messages.\n\n### Val Town\n\nThe app is configured to work with Val Town. Export uses:\n```typescript\nexport default (typeof Deno !== \"undefined\" && Deno.env.get(\"valtown\")) ? app.fetch : app;\n```\n\nSQLite caching is automatically enabled when running in Val Town (detected via `valtown` environment variable).\n\n### Environment Variables\n\n- `GROQ_API_KEY` - Required for AI metadata generation (optional, will disable metadata if not set)\n- `valtown` - Automatically set by Val Town (detects environment)\n\n## Performance Tips\n\n1. **Use default recalculate mode** - Automatically skips unchanged pages\n2. **Cache is your friend** - Always populate cache before production use\n3. **Rate limiting** - Built-in rate limiting prevents WAF blocking (1 request per 3 seconds for docs, 2 requests per second for Groq API)\n4. **Hash checking** - Default recalculation mode is much faster when most content is unchanged\n\n",[189],"6575fc7c-b8e7-11f0-ba05-0224a6c84d84","AGENTS.md","6575fd58-b8e7-11f0-ba05-0224a6c84d84",6,["D",1762196442671],"You are an advanced assistant specialized in generating Val Town code.\n\n## Core Guidelines\n\n- Ask clarifying questions when requirements are ambiguous\n- Provide complete, functional solutions rather than skeleton implementations\n- Test your logic against edge cases before presenting the final solution\n- Ensure all code follows Val Town's specific platform requirements\n- If a section of code that you're working on is getting too complex, consider refactoring it into subcomponents\n\n## Code Standards\n\n- Generate code in TypeScript or TSX\n- Add appropriate TypeScript types and interfaces for all data structures\n- Prefer official SDKs or libraries than writing API calls directly\n- Ask the user to supply API or library documentation if you are at all unsure about it\n- **Never bake in secrets into the code** - always use environment variables\n- Include comments explaining complex logic (avoid commenting obvious operations)\n- Follow modern ES6+ conventions and functional programming practices if possible\n\n## Types of triggers\n\n### 1. HTTP Trigger\n\n- Create web APIs and endpoints\n- Handle HTTP requests and responses\n- Example structure:\n\n```ts\nexport default async function (req: Request) {\n return new Response(\"Hello World\");\n}\n```\n\nFiles that are HTTP triggers have http in their name like `foobar.http.tsx`\n\n### 2. Cron Triggers\n\n- Run on a schedule\n- Use cron expressions for timing\n- Example structure:\n\n```ts\nexport default async function () {\n // Scheduled task code\n}\n```\n\nFiles that are Cron triggers have cron in their name like `foobar.cron.tsx`\n\n### 3. Email Triggers\n\n- Process incoming emails\n- Handle email-based workflows\n- Example structure:\n\n```ts\nexport default async function (email: Email) {\n // Process email\n}\n```\n\nFiles that are Email triggers have email in their name like `foobar.email.tsx`\n\n\n## Val Town Standard Libraries\n\nVal Town provides several hosted services and utility functions.\n\n### Blob Storage\n\n```ts\nimport { blob } from \"https://esm.town/v/std/blob\";\nawait blob.setJSON(\"myKey\", { hello: \"world\" });\nlet blobDemo = await blob.getJSON(\"myKey\");\nlet appKeys = await blob.list(\"app_\");\nawait blob.delete(\"myKey\");\n```\n\n### SQLite\n\n```ts\nimport { sqlite } from \"https://esm.town/v/stevekrouse/sqlite\";\nconst TABLE_NAME = 'todo_app_users_2';\n// Create table - do this before usage and change table name when modifying schema\nawait sqlite.execute(`CREATE TABLE IF NOT EXISTS ${TABLE_NAME} (\n id INTEGER PRIMARY KEY AUTOINCREMENT,\n name TEXT NOT NULL\n)`);\n// Query data\nconst result = await sqlite.execute(`SELECT * FROM ${TABLE_NAME} WHERE id = ?`, [1]);\n```\n\nNote: When changing a SQLite table's schema, change the table's name (e.g., add _2 or _3) to create a fresh table.\n\n### OpenAI\n\n```ts\nimport { OpenAI } from \"https://esm.town/v/std/openai\";\nconst openai = new OpenAI();\nconst completion = await openai.chat.completions.create({\n messages: [\n { role: \"user\", content: \"Say hello in a creative way\" },\n ],\n model: \"gpt-4o-mini\",\n max_tokens: 30,\n});\n```\n\n### Email\n\n```ts\nimport { email } from \"https://esm.town/v/std/email\";\n// By default emails the owner of the val\nawait email({ \n subject: \"Hi\", \n text: \"Hi\", \n html: \"

Hi

\"\n});\n```\n\n## Val Town Utility Functions\n\nVal Town provides several utility functions to help with common project tasks.\n\n### Importing Utilities\n\nAlways import utilities with version pins to avoid breaking changes:\n\n```ts\nimport { parseProject, readFile, serveFile } from \"https://esm.town/v/std/utils@85-main/index.ts\";\n```\n\n### Available Utilities\n\n\n#### **serveFile** - Serve project files with proper content types\n\nFor example, in Hono:\n\n```ts\n// serve all files in frontend/ and shared/\napp.get(\"/frontend/*\", c => serveFile(c.req.path, import.meta.url));\napp.get(\"/shared/*\", c => serveFile(c.req.path, import.meta.url));\n```\n\n#### **readFile** - Read files from within the project:\n\n```ts\n// Read a file from the project\nconst fileContent = await readFile(\"/frontend/index.html\", import.meta.url);\n```\n\n#### **listFiles** - List all files in the project\n\n```ts\nconst files = await listFiles(import.meta.url);\n```\n\n#### **parseProject** - Extract information about the current project from import.meta.url\n\nThis is useful for including info for linking back to a val, ie in \"view source\" urls:\n\n```ts\nconst projectVal = parseProject(import.meta.url);\nconsole.log(projectVal.username); // Owner of the project\nconsole.log(projectVal.name); // Project name\nconsole.log(projectVal.version); // Version number\nconsole.log(projectVal.branch); // Branch name\nconsole.log(projectVal.links.self.project); // URL to the project page\n```\n\nHowever, it's *extremely importing* to note that `parseProject` and other Standard Library utilities ONLY RUN ON THE SERVER.\nIf you need access to this data on the client, run it in the server and pass it to the client by splicing it into the HTML page\nor by making an API request for it.\n\n## Val Town Platform Specifics\n\n- **Redirects:** Use `return new Response(null, { status: 302, headers: { Location: \"/place/to/redirect\" }})` instead of `Response.redirect` which is broken\n- **Images:** Avoid external images or base64 images. Use emojis, unicode symbols, or icon fonts/libraries instead\n- **AI Image:** To inline generate an AI image use: `

`\n- **Storage:** DO NOT use the Deno KV module for storage\n- **Browser APIs:** DO NOT use the `alert()`, `prompt()`, or `confirm()` methods\n- **Weather Data:** Use open-meteo for weather data (doesn't require API keys) unless otherwise specified\n- **View Source:** Add a view source link by importing & using `import.meta.url.replace(\"ems.sh\", \"val.town)\"` (or passing this data to the client) and include `target=\"_top\"` attribute\n- **Error Debugging:** Add `` to HTML to capture client-side errors\n- **Error Handling:** Only use try...catch when there's a clear local resolution; Avoid catches that merely log or return 500s. Let errors bubble up with full context\n- **Environment Variables:** Use `Deno.env.get('keyname')` when you need to, but generally prefer APIs that don't require keys\n- **Imports:** Use `https://esm.sh` for npm and Deno dependencies to ensure compatibility on server and browser\n- **Storage Strategy:** Only use backend storage if explicitly required; prefer simple static client-side sites\n- **React Configuration:** When using React libraries, pin versions with `?deps=react@18.2.0,react-dom@18.2.0` and start the file with `/** @jsxImportSource https://esm.sh/react@18.2.0 */`\n- Ensure all React dependencies and sub-dependencies are pinned to the same version\n- **Styling:** Default to using TailwindCSS via `` unless otherwise specified\n\n## Project Structure and Design

utils.ts # Shared types and functions\n```\n\n### Backend (Hono) Best Practices\n\n- Hono is the recommended API framework\n- Main entry point should be `backend/index.ts`\n- **Static asset serving:** Use the utility functions to read and serve project files:\n ```ts\n import { readFile, serveFile } from \"https://esm.town/v/std/utils@85-main/index.ts\";\n \n // serve all files in frontend/ and shared/\n app.get(\"/frontend/*\", c => serveFile(c.req.path, import.meta.url));\n app.get(\"/shared/*\", c => serveFile(c.req.path, import.meta.url));\n \n // For index.html, often you'll want to bootstrap with initial data\n app.get(\"/\", async c => {\n let html = await readFile(\"/frontend/index.html\", import.meta.url);\n \n // Inject data to avoid extra round-trips\n const initialData = await fetchInitialData();\n const dataScript = ``;\n \n html = html.replace(\"\", `${dataScript}`);\n return c.html(html);\n });\n ```\n- Create RESTful API routes for CRUD operations\n- Always include this snippet at the top-level Hono app to re-throwing errors to see full stack traces:\n ```ts\n // Unwrap Hono errors to see original error details\n app.onError((err, c) => {\n throw err;\n });\n ```\n\n### Database Patterns\n- Run migrations on startup or comment out for performance\n- Change table names when modifying schemas rather than altering\n- Export clear query functions with proper TypeScript typing\n\n## Common Gotchas and Solutions\n\n1. **Environment Limitations:** \n - Val Town runs on Deno in a serverless context, not Node.js\n - Code in `shared/` must work in both frontend and backend environments\n - Cannot use `Deno` keyword in shared code\n - Use `https://esm.sh` for imports that work in both environments\n\n2. **SQLite Peculiarities:**\n - Limited support for ALTER TABLE operations\n - Create new tables with updated schemas and copy data when needed\n - Always run table creation before querying\n\n3. **React Configuration:**\n - All React dependencies must be pinned to 18.2.0\n - Always include `@jsxImportSource https://esm.sh/react@18.2.0` at the top of React files\n - Rendering issues often come from mismatched React versions\n\n4. **File Handling:**\n - Val Town only supports text files, not binary\n - Use the provided utilities to read files across branches and forks\n - For files in the project, use `readFile` helpers\n\n5. **API

Implement tiered routing\n\n## Implementation Guide\n\n### Adding a New Strategy\n\n1. **Copy template**:\n ```bash\n cp answer/llama-3.3-70b-default.ts answer/my-strategy.ts\n ```\n\n2. **Modify configuration**:\n ```typescript\n const DEFAULT_MODEL = \"your-model\";\n const DEFAULT_MAX_CONTEXT_PAGES = 3;\n const DEFAULT_TEMPERATURE = 0.5;\n ```\n\n3. **Update strategy metadata**:\n ```typescript\n export const answerStrategy: AnswerStrategy = {\n name: \"my-strategy\",\n description: \"What makes it special\",\n answer: async (query, options) => { /* ... */ }\n };\n ```\n\n4. **Activate**:\n ```typescript\n // answer/index.ts\n import { answerStrategy } from \"./my-strategy.ts\";\n ```\n\n5. **Test**:\n ```bash\n curl \"http://localhost:8000/answer/info\"\n curl \"http://localhost:8000/answer?q=test\"\n ```\n\n### Testing Multiple Strategies\n\nCreate a comparison test script:\n\n```typescript\n// testing/answer-comparison.ts\nimport { questions } from \"./questions.ts\";\n\nconst strategies = [\n \"llama-3.3-70b-default\",\n \"llama-3.1-8b-fast\",\n \"mixtral-8x7b-extended\"\n];\n\nfor (const strategy of strategies) {\n for (const question of questions) {\n // Switch strategy\n // Run question\n // Collect metrics\n }\n}\n// Compare results\n```\n\n## Monitoring and Optimization\n\n### Key Metrics to Track\n\n1. **Response time breakdown**:\n - Search duration\n - Context prep duration\n - LLM duration\n - Total duration\n\n2. **Quality metrics**:\n - User feedback/ratings\n - Answer correctness\n - Relevance of sources\n\n3. **Cost metrics**:\n - Tokens per answer\n - Cost per answer\n - Monthly spend\n\n4. **Usage patterns**:\n - Question types\n - Model distribution\n - Cache hit rates\n\n### Optimization Tips\n\n1. **Speed**: \n - Profile with `enableTiming: true`\n - Optimize slowest component\n - Consider caching\n\n2. **Quality**:\n - Test with real questions\n - Tune system prompts\n - Adjust context size\n\n3. **Cost**:\n - Route by question complexity\n - Cache common answers\n - Use smaller models when possible\n\n## Future Enhancements\n\n### Multi-Strategy Routing\n\nAutomatically select strategy based on question analysis:\n\n```typescript\nasync function smartRoute(question: string) {\n const complexity = analyzeComplexity(question);\n const type = classifyQuestion(question);\n \n if (complexity === \"simple\" && type === \"factual\") {\n return \"llama-3.1-8b-fast\";\n } else if (type === \"code\") {\n return \"llama-3.3-70b-code\";\n } else if (complexity === \"complex\") {\n return \"mixtral-8x7b-extended\";\n }\n return \"llama-3.3-70b-default\";\n}\n```\n\n### Answer Caching\n\nCache answers for common questions:\n\n```typescript\nconst cachedAnswer = await cache.get(questionHash);\nif (cachedAnswer) return cachedAnswer;\n\nconst answer = await generateAnswer(question);\nawait cache.set(questionHash, answer, ttl);\n```\n\n### Follow-up Questions\n\nSupport conversation context:\n\n```typescript\nawait answerQuestion(question, {\n conversationHistory: previousQA,\n maxContextPages: 3 // Reduced to fit history\n});\n```\n\n## Resources\n\n- **Groq Models**: https://console.groq.com/docs/models\n- **Groq Pricing**: https://groq.com/pricing/\n- **Model Benchmarks**: https://console.groq.com/docs/benchmarks\n\n",[],[235,32],"7f6d8314-b9ca-11f0-8f8b-0224a6c84d84","7f6d83c8-b9ca-11f0-8f8b-0224a6c84d84",58,["D",1762293981918],"# Answer Strategies\n\nAnswer strategies implement Retrieval-Augmented Generation (RAG) to answer user questions using documentation search and LLM inference.\n\n## How It Works\n\nEach answer strategy follows this general pattern:\n\n1. **Search**: Use the active search strategy to find relevant documentation pages\n2. **Retrieve**: Get full content from the top N search results\n3. **Format**: Format the documentation as context for the LLM\n4. **Generate**: Call the Groq LLM with the context and user question to generate an answer\n\n## Active Strategy\n\nThe active strategy is selected in `answer/index.ts` by uncommenting the desired import.\n\n### Current Active Strategy\n\n**llama-3.3-70b-default** - Default strategy using Llama 3.3 70B\n- Uses up to 5 documentation pages in context\n- Truncates each page to ~2000 tokens to manage context window\n- Temperature: 0.3 (relatively focused/deterministic)\n- Model: `llama-3.3-70b-versatile`\n\n## Available Strategies\n\n### 1. llama-3.3-70b-default.ts\n\n**Best for**: General purpose Q&A with good balance of quality and speed\n\n- **Model**: `llama-3.3-70b-versatile`\n- **Context**: Up to 5 pages, 2000 tokens each\n- **Temperature**: 0.3 (default)\n- **Performance**: ~1-3s depending on search and LLM response time\n\n**Configuration options**:\n```typescript\n{\n limit: 10, // Search results to consider\n minScore: 0, // Minimum search score\n maxContextPages: 5, // Pages to include in context\n temperature: 0.3, // LLM temperature\n model: \"llama-3.3-70b-versatile\" // Override model\n}\n```\n\n## Creating New Strategies\n\nTo create a new answer strategy:\n\n1. Create a new file in `/answer/` (e.g., `llama-3.1-8b-fast.ts`)\n2. Implement the `AnswerStrategy` interface:\n\n```typescript\nimport type { AnswerStrategy, AnswerResult, AnswerOptions } from \"./types.ts\";\n\nexport const answerStrategy: AnswerStrategy = {\n name: \"your-strategy-name\",\n description: \"Brief description of your strategy\",\n \n answer: async (query: string, options: AnswerOptions = {}): Promise => {\n // Your implementation here\n // 1. Search for relevant pages\n // 2. Get full content\n // 3. Format as context\n // 4. Call LLM\n // 5. Return AnswerResult\n },\n};\n```\n\n3. Add the import to `answer/index.ts` and comment out other strategies\n4. Test your strategy\n\n### Strategy Ideas\n\nHere are some ideas for additional strategies you might want to implement:\n\n- **llama-3.1-8b-fast**: Faster responses with smaller model, fewer pages\n- **mixtral-8x7b-extended**: More context pages with Mixtral's larger context window\n- **llama-3.3-70b-code-focused**: Specialized prompts for code examples and API usage\n- **multi-step-reasoning**: Break down complex questions into sub-questions\n- **citation-mode**: Include specific citations/references in the answer\n- **conversational**: Support follow-up questions with conversation history\n\n## API Usage\n\n### Basic Answer Request\n\n```bash\nGET /answer?q=How+do+I+use+the+Groq+API\n```\n\n### With Options\n\n```bash\nGET /answer?q=What+models+are+available&maxContextPages=3&temperature=0.5\n```\n\n### Get Strategy Info\n\n```bash\nGET /answer/info\n```\n\n## Response Format\n\n```json\n{\n \"answer\": \"markdown formatted answer\",\n \"query\": \"user's original question\",\n \"searchResults\": [\n {\n \"path\": \"api/reference\",\n \"url\": \"https://...\",\n \"title\": \"API Reference\",\n \"score\": 95.2\n }\n ],\n \"contextUsed\": 5,\n \"totalTokens\": 8500,\n \"metadata\": {\n \"strategy\": \"llama-3.3-70b-default\",\n \"model\": \"llama-3.3-70b-versatile\",\n \"temperature\": 0.3,\n \"searchResultsCount\": 10,\n \"timings\": {\n \"search\": 45.2,\n \"contextPrep\": 5.1,\n \"llm\": 1250.3,\n \"total\": 1300.6\n }\n }\n}\n```\n\n## Tuning Your Strategy\n\n### Context Size\n\n- **More pages** = more comprehensive but slower and more expensive\n- **Fewer pages** = faster but might miss relevant info\n- Recommended: 3-5 pages for most questions\n\n### Token Limits\n\n- **Per page**: 1000-3000 tokens is a good range\n- **Total context**: Stay under 32k tokens for most models\n- Llama 3.3 70B supports up to 128k context, but quality may degrade\n\n### Temperature\n\n- **0.0-0.3**: Focused, deterministic answers (good for facts)\n- **0.4-0.7**: Balanced creativity and accuracy\n- **0.8-1.0**: More creative but less consistent (avoid for docs Q&A)\n\n### Search Configuration\n\n- **Higher limit**: More pages to choose from (10-20 recommended)\n- **Higher minScore**: Only use highly relevant pages (50-70 threshold)\n- Balance between precision (fewer, better pages) and recall (more pages, might miss relevant info)\n\n## Best Practices\n\n1. **Match model to task**:\n - Simple factual questions: Smaller/faster models\n - Complex reasoning: Larger models (70B+)\n - Code generation: Models fine-tuned for code\n\n2. **System prompts matter**:\n - Be specific about the documentation domain (Groq API)\n - Set expectations for answer format (markdown, citations, etc.)\n - Provide guidelines for handling missing information\n - Include URL formatting instructions (e.g., \"remove .md extensions\")\n\n3. **Manage context window**:\n - Don't just dump all pages - be selective\n - Truncate long pages intelligently\n - Consider summarizing very long pages first\n\n4. **Error handling**:\n - Gracefully handle search failures\n - Provide fallback responses when LLM fails\n - Include relevant metadata for debugging\n\n5. **Post-processing**:\n - Use `cleanupMarkdownLinks()` to remove .md extensions from generated links\n - Add custom post-processing for your specific needs\n - Validate links and citations if needed\n\n## URL Cleanup\n\nAnswers automatically clean up markdown links to remove `.md` extensions:\n\n```typescript\n// Before cleanup\n[Compound](https://console.groq.com/docs/agentic-tooling/compound-beta.md)\n\n// After cleanup \n[Compound](https://console.groq.com/docs/agentic-tooling/compound-beta)\n```\n\nThis happens through:\n1. **System prompt**: Instructs the LLM to avoid .md extensions\n2. **Post-processing**: `cleanupMarkdownLinks()` function removes any remaining .md extensions\n\nTo disable cleanup (not recommended):\n```typescript\n// In your custom strategy, skip the cleanup:\nreturn {\n answer: llmResponse, // Don't call cleanupMarkdownLinks()\n // ... rest of result\n};\n```\n\n## Testing\n\nTest your strategy with various question types:\n\n- **Factual**: \"What models does Groq support?\"\n- **How-to**: \"How do I authenticate with the API?\"\n- **Comparison**: \"What's the difference between model X and Y?\"\n- **Code examples**: \"Show me an example of streaming responses\"\n- **Complex**: \"How do I implement rate limiting with retries?\"\n\n## Performance Benchmarks\n\nTarget performance for answer strategies:\n\n- **Search**: 50-500ms (depends on active search strategy)\n- **Context prep**: <50ms\n- **LLM call**: 500-3000ms (depends on model and response length)\n- **Total**: 1-4s for most queries\n\nStrategies taking >5s should be optimized or marked as \"detailed\" mode.\n\n",[],[235,189],"7f58d5d6-b9ca-11f0-afaf-0224a6c84d84","QUICK-START.md","7f58d680-b9ca-11f0-afaf-0224a6c84d84",56,["D",1762293981932],"# Answer Strategies - Quick Start Guide\n\nThis guide will help you quickly get started with answer strategies for RAG-based question answering.\n\n## What Are Answer Strategies?\n\nAnswer strategies implement **Retrieval-Augmented Generation (RAG)** - they search documentation, retrieve relevant pages, and use an LLM to generate answers to user questions.\n\n## Quick Test\n\n### 1. Run Tests Locally (Recommended)\n\n```bash\n# Run comprehensive test suite with timing breakdown\ndeno task answer\n```\n\nThis will:\n- Load test questions from `testing/questions.ts`\n- Run each question through the active answer strategy\n- Show detailed timing breakdown (search, context prep, LLM call)\n- Display search results used for context\n- Show generated answers\n- Provide summary statistics\n\n### 2. Test via API Endpoints\n\n#### Start the Server\n\n```bash\ndeno task serve\n```\n\n#### Test Single Questions\n\n```bash\n# Basic question\ncurl \"http://localhost:8000/answer?q=How+do+I+use+the+Groq+API\"\n\n# With options\ncurl \"http://localhost:8000/answer?q=What+models+are+available&maxContextPages=3\"\n\n# Get strategy info\ncurl \"http://localhost:8000/answer/info\"\n\n# Run test suite via API\ncurl \"http://localhost:8000/answer/test\"\n```\n\n## How It Works\n\n### Step-by-Step Process\n\n1. **User asks a question**: \"How do I authenticate with the Groq API?\"\n\n2. **Search** (50-500ms): The active search strategy finds relevant docs\n ```\n → Search query: \"authenticate groq api\"\n → Returns: Top 10 matching pages ranked by relevance\n ```\n\n3. **Retrieve** (fast, from cache): Get full content for top 5 pages\n ```\n → Loads content from latest.json (local cache)\n → Each page limited to ~2000 tokens\n ```\n\n4. **Format** (<50ms): Package docs as LLM context\n ```\n → Formats pages with titles, URLs, and content\n → Adds system prompt with instructions\n → Creates user prompt with question\n ```\n\n5. **Generate** (500-3000ms): LLM generates answer\n ```\n → Calls Groq API with Llama 3.3 70B\n → Returns markdown-formatted answer\n → Includes citations and examples from docs\n ```\n\n## Understanding the Response\n\n```json\n{\n \"answer\": \"To authenticate with the Groq API...\",\n \"query\": \"How do I authenticate with the Groq API?\",\n \"searchResults\": [\n {\n \"path\": \"api/authentication\",\n \"url\": \"https://console.groq.com/docs/api/authentication\",\n \"title\": \"Authentication\",\n \"score\": 92.5\n }\n ],\n \"contextUsed\": 5,\n \"totalTokens\": 8500,\n \"metadata\": {\n \"strategy\": \"llama-3.3-70b-default\",\n \"model\": \"llama-3.3-70b-versatile\",\n \"temperature\": 0.3,\n \"searchResultsCount\": 10,\n \"timings\": {\n \"search\": 45.2,\n \"contextPrep\": 5.1,\n \"llm\": 1250.3,\n \"total\": 1300.6\n }\n }\n}\n```\n\n### Key Fields\n\n- **answer**: The LLM-generated answer (markdown formatted)\n- **query**: Your original question\n- **searchResults**: Top pages used as context (with scores)\n- **contextUsed**: Number of pages actually sent to the LLM\n- **totalTokens**: Approximate tokens in the context\n- **metadata.timings**: Performance breakdown\n\n## Switching Strategies\n\n### Current Strategy\n\nThe active strategy is set in `answer/index.ts`:\n\n```typescript\n// Default: Llama 3.3 70B with up to 5 doc pages\nimport { answerStrategy } from \"./llama-3.3-70b-default.ts\";\n```\n\n### Available Strategies\n\nCurrently available:\n- ✅ **llama-3.3-70b-default**: Balanced quality and speed\n\nComing soon (you can implement these!):\n- ⚡ **llama-3.1-8b-fast**: Faster responses with smaller model\n- 📚 **mixtral-8x7b-extended**: More context with larger model\n- 💻 **llama-3.3-70b-code**: Optimized for code examples\n- 🔗 **citation-mode**: Includes specific citations\n\n### Switching\n\n1. Comment out current strategy in `answer/index.ts`\n2. Uncomment the strategy you want to use\n3.

Use faster models (8B instead of 70B)\n2. Reduce context pages (2-3 instead of 5)\n3. Use faster search strategy\n4. Lower token limits per page\n\n### Optimize for Quality\n\n1. Use larger models (70B+)\n2. Increase context pages (7-10)\n3. Use higher search score thresholds\n4. Include more search results to choose from\n\n### Balance Both\n\n1. Start with default (5 pages, 70B, temp 0.3)\n2. Monitor timing breakdown in responses\n3. Adjust based on question complexity\n4. Cache common questions (future enhancement)\n\n## Next Steps\n\n1. ✅ Test the default strategy\n2. ✅ Try different query parameters\n3. ✅ Check the README.md for more details\n4. ⚡ Create a fast strategy for simple questions\n5. 📚 Create an extended strategy for complex questions\n6. 🔧 Customize system prompts for your use case\n7. 📊 Build a testing harness (like `/search/test`)\n\n## Resources\n\n- **Search Strategies**: See `/search/` for how document retrieval works\n- **Groq Models**: https://console.groq.com/docs/models\n- **API Reference**: https://console.groq.com/docs/api-reference\n\n## Questions?\n\nCheck out:\n- `answer/README.md` - Detailed documentation\n- `answer/types.ts` - Type definitions\n- `answer/utils.ts` - Helper functions\n- `main.tsx` - How endpoints are implemented\n\n",[],[235,520],"7f40d292-b9ca-11f0-8b68-0224a6c84d84",".gitkeep","7f40d350-b9ca-11f0-8b68-0224a6c84d84",53,["D",1762293981787],"# Answer Strategies Directory\n\nThis folder contains RAG (Retrieval-Augmented Generation) strategies for answering questions about Groq documentation.\n\nSee README.md and QUICK-START.md for documentation.\n\n",[],[235,528],["D",1762293980863],[251,252,253,254,255,256,257,258],[235],["D",1746217442601],{"_94":93,"_101":97},{"_94":93,"_95":-5,"_96":97,"_18":53,"_98":99,"_100":24},{"_13":83,"_31":84,"_41":40,"_85":42,"_86":-5,"_87":-5,"_88":-5,"_89":-5,"_90":-5,"_91":43,"_92":93},"ctx",{"_76":-5,"_121":575,"_576":577,"_578":579,"_580":24,"_581":24,"_582":24,"_583":47,"_584":-5,"_585":-7,"_586":-7,"_587":60,"_588":24,"_589":24,"_590":-5,"_591":24,"_592":24,"_593":24,"_594":-5},"ENV",{"_546":547,"_548":549,"_550":84,"_551":552,"_553":554,"_555":556,"_557":558,"_559":560,"_561":562,"_563":564,"_565":566,"_567":568,"_569":570,"_571":572,"_573":574},"REACT_APP_SENTRY_DSN","https://586020d86f05489db63a554690acf1e9@o1398359.ingest.sentry.io/6724499","RENDER_GIT_COMMIT","5015b8df46402d8bba4f485ecc37aec202b0e06b","RENDER_GIT_BRANCH","POSTHOG_API_TOKEN","phc_nmoyuAkStEZuUp69rYlg1DZgrIt19Gx0Y4Hwf8tGgJP","POSTHOG_API_HOST","https://wart.val.town","WEB_API_TEMPLATE","https://{val}.web.val.run","APP_URL","https://www.val.town","MODULE_URL","https://esm.town","VANITY_WEB_API_TEMPLATE","https://{label}.val.run/","DENOLS_URL","https://lsp.val.town","NODE_ENV","production","CLOUDFLARE_TURNSTILE_SITE_KEY","0x4AAAAAACtaIZJH7s9rBMZ6","GOOGLE_CLIENT_ID","875989696899-jtsqkhlbdv5jrlsk8631p7ipjg3c6o62.apps.googleusercontent.com","STRIPE_PUBLISHABLE_KEY","pk_live_51N2zvWEpZTTLipIkVEwXrUG9AT0yeOOEYxszarZT1jpsZV58Ly6wlg3SltZpHN26CUalOBmUSY7adQRQiSkCZz2500qSXNkf8Y","API_URL","https://api.val.town",[],"preferencesKeybindings","default","preferencesTheme","light","preferencesFixers","preferencesCopilot","preferencesSelectionAi","preferencesCloseBrackets","preferencesChatPanelState","preferencesDprint","preferencesDenofmt","notificationCount","flagDenols","isBusinessOrgMember","businessOrgHandle","isBusinessOrgAdmin","isHigherTownieTier","navCollapsed","currentOrgId"]
