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│ └──

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

`\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- **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- Do NOT use Hono serveStatic middleware\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/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\n6. **Hono Peculiarities:**\n - NEVER EVER write this line: `import { serveStatic } from 'https://esm.sh/hono@3.11.7/middleware';`\n - Instead use: `import { readFile, serveFile } from \"https://esm.town/v/std/utils/index.ts\";`\n - NEVER EVER write this line: `import { cors } from \"https://esm.sh/@hono/cors@0.0.6\";`. \n - Val Town automatically handles CORS.\n - If you need cookies, use: import { deleteCookie, getCookie, setCookie } from \"npm:hono/cookie\";",[],[313,306],"prompts","0a705786-3d1e-11f0-b042-76b3cceeab13","open_townie_prompt_additions.txt","792e32f2-a722-46db-856e-7ea6401e1295",["D",1748585968110],"Read files from the base directory / directly, not /repo/.\n\nWhen trying to understand the directory, first read README.md.\nWhenever you make a change to the code, \nbe sure to keep the README.md up to date unless the user asks you not to.\n\nYou can implicitly create directories, by creating files within the directories. For example, if you wanted to create `/foo/bar/baz.ts`, \nbut the foo and bar directories did not exist, you could still use the file editor tool to create /foo/bar/baz.ts, and trust that the \n`/foo/` and `/foo/bar/` directories will be created for you automatically.\n\nDefault to using str_replace in smaller chunks wherever possible. \nIf you're making extensive edits to a file, replace the file with the replace file tool.\n\nWhen files are provided in user messages under \"# Selected Project Files\", DO NOT use tools to re-read these files. \nTrust that these files are the most up-to-date versions and work with the content as provided in the message.\nOnly use the file editing tools to read files that haven't been shared with you yet or to make changes to files.\n\nThink carefully and only action the specific task you are given with the most concise and elegant\nsolution that changes as little code as possible.\n\nUse your 'fetch' tool to debug HTTP vals making

calls.\n\n## Features\n\n- User summary view with aggregated usage data\n- All requests view with collapsible rows showing inference calls\n- Inference calls view with filtering options\n- Pagination for handling large datasets\n- Comparison between usage data and inference calls for debugging\n- Fallback to inference data when usage data is missing\n\n## Architecture\n\nThe dashboard is built with a modular architecture:\n\n```\n/usage-dashboard/\n index.ts # Main entry point and routing\n auth.ts # Authentication logic\n /api/\n index.ts # API request handler\n requests.ts # API endpoints for requests data\n inference-calls.ts # API endpoints for inference calls\n user-summary.ts # API endpoints for user summary data\n /views/\n layout.ts # Common layout template\n dashboard.ts # User summary view\n requests.ts # Requests view with collapsible rows\n inference-calls.ts # Inference calls view\n /utils/\n formatters.ts # Shared formatting utilities\n pagination.ts # Pagination utilities\n```\n\n## Usage\n\nAccess the dashboard at the root URL. Authentication is required.\n\n### Views\n\n1. **User Summary** - Shows aggregated usage data by user\n - When usage data is missing, it falls back to inference call data\n - Indicated with an \"I\" badge\n\n2. **All Requests** - Shows all usage requests with pagination\n - Click on a row to see associated inference calls\n - Compares usage data with inference call totals\n - Highlights discrepancies for debugging\n\n3. **Inference Calls** - Shows all inference calls with pagination\n - Can be filtered by usage_id\n - Links back to the associated request\n\n### API Endpoints\n\n- `/api/requests` - Get paginated requests\n- `/api/requests?usage_id=123` - Get a specific request\n- `/api/inference-calls` - Get paginated inference calls\n- `/api/inference-calls?usage_id=123` - Get inference calls for a specific request\n- `/api/user-summary` - Get user summary data\n\n## Debugging\n\nThe dashboard includes several features for debugging:\n\n1. **Collapsible Rows** - Click on a request to see its inference calls\n2. **Token Comparison** - Compare tokens and price between usage and inference data\n3. **Discrepancy Highlighting** - Visual indicators when data doesn't match\n4. **Inference Data Fallback** - Use inference data when usage data is missing",[],[609,738,752,289],"0a6f8158-3d1e-11f0-b042-76b3cceeab13","requests.ts","b01d7ac4-4e86-4cc8-bc25-1b0cee896228","1dd12584-7931-4ffc-8a83-fb9aae9928bf",["D",1748585968110],"import { renderLayout } from \"./layout.ts\";\nimport { formatNumber, formatPrice, formatDate, formatBoolean } from \"../utils/formatters.ts\";\nimport { renderPaginationControls } from \"../utils/pagination.ts\";\n\ninterface RequestRow {\n id: number;\n username: string;\n timestamp: number;\n val_id: string;\n branch_id: string | null;\n input_tokens: number | null;\n output_tokens: number | null;\n cache_read_tokens: number | null;\n cache_write_tokens: number | null;\n model: string;\n price: number | null;\n finish_reason: string | null;\n num_images: number | null;\n our_api_token: number;\n}\n\ninterface PaginationData {\n currentPage: number;\n totalPages: number;\n pageSize: number;\n totalItems: number;\n hasNextPage: boolean;\n hasPrevPage: boolean;\n}\n\nexport function renderRequests(data: RequestRow[], pagination: PaginationData, baseUrl: string): string {\n // Calculate totals\n const totalRequests = pagination.totalItems;\n const totalPrice = data.reduce((sum, row) => sum + (row.price || 0), 0);\n \n // Generate pagination controls\n const paginationControls = renderPaginationControls(pagination, baseUrl);\n \n // Client-side script for collapsible rows\n const script = `\n // Function to toggle inference details\n function toggleInferenceDetails(usageId) {\n const detailsElement = document.getElementById('inference-' + usageId);\n \n if (detailsElement) {\n // Toggle visibility of existing details\n detailsElement.classList.toggle('visible');\n } else {\n // Create a placeholder while loading\n const row = document.querySelector('tr[data-id=\"' + usageId + '\"]');\n const colSpan = row.querySelectorAll('td').length;\n const newRow = document.createElement('tr');\n newRow.id = 'inference-' + usageId;\n newRow.classList.add('inference-details', 'visible');\n newRow.innerHTML = 'Loading inference calls...';\n row.parentNode.insertBefore(newRow, row.nextSibling);\n \n // Fetch the inference calls data\n fetch('/api/inference-calls?usage_id=' + usageId)\n .then(response => response.json())\n .then(data => {\n // Calculate totals from inference calls\n const totalInputTokens = data.data.reduce((sum, call) => sum + (call.input_tokens || 0), 0);\n const totalOutputTokens = data.data.reduce((sum, call) => sum + (call.output_tokens || 0), 0);\n const totalCacheReadTokens = data.data.reduce((sum, call) => sum + (call.cache_read_tokens || 0), 0);\n const totalCacheWriteTokens = data.data.reduce((sum, call) => sum + (call.cache_write_tokens || 0), 0);\n const totalPrice = data.data.reduce((sum, call) => sum + (call.price || 0), 0);\n \n // Get the usage row data\n const usageRow = document.querySelector('tr[data-id=\"' + usageId + '\"]');\n const usageInputTokens = parseInt(usageRow.getAttribute('data-input-tokens') || '0');\n const usageOutputTokens = parseInt(usageRow.getAttribute('data-output-tokens') || '0');\n const usageCacheReadTokens = parseInt(usageRow.getAttribute('data-cache-read-tokens') || '0');\n const usageCacheWriteTokens = parseInt(usageRow.getAttribute('data-cache-write-tokens') || '0');\n const usagePrice = parseFloat(usageRow.getAttribute('data-price') || '0');\n \n // Check for discrepancies\n const inputDiscrepancy = totalInputTokens !== usageInputTokens && usageInputTokens !== 0;\n const outputDiscrepancy = totalOutputTokens !== usageOutputTokens && usageOutputTokens !== 0;\n const cacheReadDiscrepancy = totalCacheReadTokens !== usageCacheReadTokens && usageCacheReadTokens !== 0;\n const cacheWriteDiscrepancy = totalCacheWriteTokens !== usageCacheWriteTokens && usageCacheWriteTokens !== 0;\n const priceDiscrepancy = Math.abs(totalPrice -
