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 Patterns\n\n### Recommended Directory Structure\n```\n├── backend/\n│ ├── database/\n│ │ ├── migrations.ts # Schema definitions\n│ │ ├── queries.ts # DB query functions\n│ │ └── README.md\n│ └── routes/ # Route modules\n│ ├── [route].ts\n│ └── static.ts # Static file serving\n│ ├── index.ts # Main entry point\n│ └── README.md\n├── frontend/\n│ ├── components/\n│ │ ├── App.tsx\n│ │ └── [Component].tsx\n│ ├── favicon.svg\n│ ├── index.html # Main HTML template\n│ ├── index.tsx # Frontend JS entry point\n│ ├── README.md\n│ └── style.css\n├── README.md\n└── shared/\n ├── README.md\n └── 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 Design:**\n - `fetch` handler is the entry point for HTTP vals\n - Run the Hono app with `export default app.fetch // This is the entry point for HTTP vals`\n\n",[],[296],"923efc20-b9ca-11f0-8426-0224a6c84d84",".vtignore","65892b4e-b8e7-11f0-ba05-0224a6c84d84",104,["D",1762294013641],".git\n.vscode\n.cursorrules\n.DS_Store\nnode_modules\nvendor\ndata\nsearch/models",[],[304],["D",1762293982187],[],[18,64],["D",1762293981048],[225],[18],"80d9bda8-b9ca-11f0-bf21-0224a6c84d84","test-search.ts","31b6d70c-b901-11f0-bfbc-0224a6c84d84","30dc0668-b901-11f0-a3b9-0224a6c84d84",101,["D",1762293984423],"// Test script for search strategies\n// Run with: deno task test-search\n// Requires: Run `deno task recalculate` first to generate /data/latest.json\n\nimport \"jsr:@std/dotenv/load\";\nimport { getAllPagesForSearch } from \"../main.tsx\";\nimport { runSearchTest } from \"./search-harness.ts\";\nimport { questions } from \"./questions.ts\";\n\nasync function testSearchStrategies() {\n const overallStart = performance.now();\n const timings: Record = {};\n \n // Load cached data from latest.json\n let cachedData: any = null;\n const loadJsonStart = performance.now();\n try {\n const latestData = await Deno.readTextFile(\"./data/latest.json\");\n timings.jsonReadFile = performance.now() -

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",[],[388,486],"8039999a-b9ca-11f0-9362-0224a6c84d84","80399a58-b9ca-11f0-9362-0224a6c84d84",83,["D",1762293983419],"# Search Module\n\nPluggable semantic search system with multiple embedding strategies.\n\n## Quick Start\n\n### 1.

Check which strategy is active\n2. Ensure model is cached (first run is slower)\n3. Try quantized model (`USE_QUANTIZED = true`)\n4. Check network latency (for API-based strategies)\n\n### Different embedding dimensions\n\nIf switching strategies with different dimensions:\n```bash\nGET /cache/recalculate?force=true\n```\n\nThis regenerates all embeddings with the new strategy.\n\n## Contributing\n\nTo add a new search strategy:\n\n1. Create `search/my-strategy.ts`\n2.

Popular options:\n\n- **all-MiniLM-L6-v2** (default) - 384 dims, 23MB, fast\n- **all-mpnet-base-v2** - 768 dims, 420MB, more accurate\n- **paraphrase-multilingual-MiniLM-L12-v2** - 384 dims, 470MB, multilingual\n\nTo use a different model:\n1. Download it to `search/models/[model-name]`\n2. Update `MODEL_PATH` in `transformers-local-onnx.ts`\n3. Update embedding dimension in your data pipeline if needed\n\n## Clean Up\n\nTo remove the model and reclaim disk space:\n\n```bash\ncd search/models\nrm -rf all-MiniLM-L6-v2\n```\n\nThen switch back to a different strategy in `search/index.ts`.\n\n",[],[388,517,543],"7fdcccf6-b9ca-11f0-9362-0224a6c84d84","7fdccdbe-b9ca-11f0-9362-0224a6c84d84",72,["D",1762293982616],"# Local ONNX Models\n\nThis directory contains pre-downloaded ONNX models for local embedding generation.\n\n## Setup Instructions\n\n### 1.

Verify the Files\n\nYour directory structure should look like:\n\n```\nmodels/\n all-MiniLM-L6-v2/\n onnx/\n model.onnx # ~23MB - the main ONNX model\n model_quantized.onnx # ~6MB - quantized version (optional, faster)\n tokenizer.json # Tokenizer configuration\n tokenizer_config.json # Additional tokenizer settings\n config.json # Model configuration\n```\n\n### 3. Switch to Local Model Strategy\n\nIn `search/index.ts`, uncomment the local model strategy:\n\n```typescript\nimport { searchStrategy, generateEmbeddings } from \"./transformers-local-onnx.ts\";\n```\n\n## Model Details\n\n- **Model**: all-MiniLM-L6-v2 (Sentence Transformers)\n- **Dimensions**: 384\n- **Size**: ~23MB (full) or ~6MB (quantized)\n- **Speed**: ~10-30ms per embedding (after initial load)\n- **Advantage**: No network calls, works offline, completely local\n\n## Notes\n\n- The model files are binary and should be kept in this directory\n- The quantized model (`model_quantized.onnx`) is smaller and faster but slightly less accurate\n- This strategy requires the model files to be present before running\n- For deployment, ensure these files are included in your build/deployment package\n\n### About the \"mutex lock failed\" Error\n\nYou may see this error when running test scripts:\n```\nlibc++abi: terminating due to uncaught exception of type std::__1::system_error: mutex lock failed: Invalid argument\n```\n\n**This is harmless and expected!** Here's why:\n- The error happens in ONNX runtime's C++ cleanup code when the process exits\n- It occurs **after** all work is completed successfully\n- It **does not** affect functionality, data, or results\n- It only appears when scripts exit immediately\n- Long-running servers (like your main app) typically don't exit, so you won't see this in production\n\n**What to do**: Just ignore the error message. All tests pass successfully before it appears.\n\n",[],[388,517,288],"7fc802e4-b9ca-11f0-a8b3-0224a6c84d84",".gitignore","7fc80370-b9ca-11f0-a8b3-0224a6c84d84",70,["D",1762293982674],"# Ignore all downloaded model files (they're large!)\nall-MiniLM-L6-v2/\n\n# But keep the README and download script\n!README.md\n!download-model.sh\n!.gitignore\n\n",[],[388,517,558],"7fd41336-b9ca-11f0-8b68-0224a6c84d84","tokenizer_config.json","7fd413ea-b9ca-11f0-8b68-0224a6c84d84","7f049ff2-b9ca-11f0-98dd-0224a6c84d84",71,["D",1762293982754],"{\n \"clean_up_tokenization_spaces\": true,\n \"cls_token\": \"[CLS]\",\n \"do_basic_tokenize\": true,\n \"do_lower_case\": true,\n \"mask_token\": \"[MASK]\",\n \"model_max_length\": 512,\n \"never_split\": null,\n \"pad_token\": \"[PAD]\",\n \"sep_token\": \"[SEP]\",\n \"strip_accents\": null,\n \"tokenize_chinese_chars\": true,\n \"tokenizer_class\": \"BertTokenizer\",\n \"unk_token\": \"[UNK]\"\n}\n",[],[388,517,574,566],"all-MiniLM-L6-v2","7ff2d50a-b9ca-11f0-83d0-0224a6c84d84","special_tokens_map.json","7ff2d5a0-b9ca-11f0-83d0-0224a6c84d84",75,["D",1762293982796],"{\n \"cls_token\": \"[CLS]\",\n \"mask_token\": \"[MASK]\",\n \"pad_token\": \"[PAD]\",\n \"sep_token\": \"[SEP]\",\n \"unk_token\": \"[UNK]\"\n}\n",[],[388,517,574,576],"8013cf8a-b9ca-11f0-8051-0224a6c84d84","config.json","8013d052-b9ca-11f0-8051-0224a6c84d84",79,["D",1762293983167],"{\n \"_name_or_path\": \"sentence-transformers/all-MiniLM-L6-v2\",\n \"architectures\": [\n \"BertModel\"\n ],\n \"attention_probs_dropout_prob\": 0.1,\n \"classifier_dropout\": null,\n \"gradient_checkpointing\": false,\n \"hidden_act\": \"gelu\",\n \"hidden_dropout_prob\": 0.1,\n \"hidden_size\": 384,\n \"initializer_range\": 0.02,\n \"intermediate_size\": 1536,\n \"layer_norm_eps\": 1e-12,\n \"max_position_embeddings\": 512,\n \"model_type\": \"bert\",\n \"num_attention_heads\": 12,\n \"num_hidden_layers\": 6,\n \"pad_token_id\": 0,\n \"position_embedding_type\": \"absolute\",\n \"transformers_version\": \"4.29.2\",\n \"type_vocab_size\": 2,\n \"use_cache\": true,\n \"vocab_size\": 30522\n}\n",[],[388,517,574,584],"801cceb4-b9ca-11f0-8b68-0224a6c84d84","801ccf7c-b9ca-11f0-8b68-0224a6c84d84",80,["D",1762293983230],"---\nbase_model: sentence-transformers/all-MiniLM-L6-v2\nlibrary_name: transformers.js\nlicense: apache-2.0\n---\n\nhttps://huggingface.co/sentence-transformers/all-MiniLM-L6-v2 with ONNX weights to be compatible with Transformers.js.\n\n## Usage (Transformers.js)\n\nIf you haven't already, you can install the [Transformers.js](https://huggingface.co/docs/transformers.js) JavaScript library from [NPM](https://www.npmjs.com/package/@huggingface/transformers) using:\n```bash\nnpm i @huggingface/transformers\n```\n\nYou can then use the model to compute embeddings like this:\n\n```js\nimport { pipeline } from '@huggingface/transformers';\n\n// Create a feature-extraction pipeline\nconst extractor = await pipeline('feature-extraction', 'Xenova/all-MiniLM-L6-v2');\n\n// Compute sentence embeddings\nconst sentences = ['This is an example sentence', 'Each sentence is converted'];\nconst output = await extractor(sentences, { pooling: 'mean', normalize: true });\nconsole.log(output);\n// Tensor {\n// dims: [ 2, 384 ],\n// type: 'float32',\n// data: Float32Array(768) [ 0.04592696577310562, 0.07328180968761444, ... ],\n// size: 768\n// }\n```\n\nYou can convert this Tensor to a nested JavaScript array using `.tolist()`:\n```js\nconsole.log(output.tolist());\n// [\n// [ 0.04592696577310562, 0.07328180968761444, 0.05400655046105385, ... ],\n// [ 0.08188057690858841, 0.10760223120450974, -0.013241755776107311, ... ]\n// ]\n```\n\nNote: Having a separate repo for ONNX weights is intended to be a temporary solution until WebML gains more traction. If you would like to make your models web-ready, we recommend converting to ONNX using [🤗 Optimum](https://huggingface.co/docs/optimum/index) and structuring your repo like this one (with ONNX weights

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",[],[691,486],"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",[],[691,288],"7f58d5d6-b9ca-11f0-afaf-0224a6c84d84","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.
