{"model":"claude-opus-4-20250514","tools":[{"name":"Bash","description":"Executes a given bash command in a persistent shell session with optional timeout, ensuring proper handling and security measures.\n\nBefore executing the command, please follow these steps:\n\n1. Directory Verification:\n - If the command will create new directories or files, first use the LS tool to verify the parent directory exists and is the correct location\n - For example, before running \"mkdir foo/bar\", first use LS to check that \"foo\" exists and is the intended parent directory\n\n2. Command Execution:\n - Always quote file paths that contain spaces with double quotes (e.g., cd \"path with spaces/file.txt\")\n - Examples of proper quoting:\n - cd \"/Users/name/My Documents\" (correct)\n - cd /Users/name/My Documents (incorrect - will fail)\n - python \"/path/with spaces/script.py\" (correct)\n - python /path/with spaces/script.py (incorrect - will fail)\n - After ensuring proper quoting, execute the command.\n - Capture the output of the command.\n\nUsage notes:\n - The command argument is required.\n - You can specify an optional timeout in milliseconds (up to 300000ms / 5 minutes). If not specified, commands will timeout after 300000ms (5 minutes).\n - It is very helpful if you write a clear, concise description of what this command does in 5-10 words.\n - If the output exceeds 30000 characters, output will be truncated before being returned to you.\n - VERY IMPORTANT: You MUST avoid using search commands like `find` and `grep`. Instead use Grep, Glob, or Task to search. You MUST avoid read tools like `cat`, `head`, `tail`, and `ls`, and use Read and LS to read files.\n - If you _still_ need to run `grep`, STOP. ALWAYS USE ripgrep at `rg` first, which all ${PRODUCT_NAME} users have pre-installed.\n - When issuing multiple commands, use the ';' or '&&' operator to separate them. DO NOT use newlines (newlines are ok in quoted strings).\n - Try to maintain your current working directory throughout the session by using absolute paths and avoiding usage of `cd`. You may use `cd` if the User explicitly requests it.\n <good-example>\n pytest /foo/bar/tests\n </good-example>\n <bad-example>\n cd /foo/bar && pytest tests\n </bad-example>\n\n\n\n\n# Committing changes with git\n\nWhen the user asks you to create a new git commit, follow these steps carefully:\n\n1. You have the capability to call multiple tools in a single response. When multiple independent pieces of information are requested, batch your tool calls together for optimal performance. ALWAYS run the following bash commands in parallel, each using the Bash tool:\n - Run a git status command to see all untracked files.\n - Run a git diff command to see both staged and unstaged changes that will be committed.\n - Run a git log command to see recent commit messages, so that you can follow this repository's commit message style.\n2. Analyze all staged changes (both previously staged and newly added) and draft a commit message:\n - Summarize the nature of the changes (eg. new feature, enhancement to an existing feature, bug fix, refactoring, test, docs, etc.). Ensure the message accurately reflects the changes and their purpose (i.e. \"add\" means a wholly new feature, \"update\" means an enhancement to an existing feature, \"fix\" means a bug fix, etc.).\n - Check for any sensitive information that shouldn't be committed\n - Draft a concise (1-2 sentences) commit message that focuses on the \"why\" rather than the \"what\"\n - Ensure it accurately reflects the changes and their purpose\n3. You have the capability to call multiple tools in a single response. When multiple independent pieces of information are requested, batch your tool calls together for optimal performance. ALWAYS run the following commands in parallel:\n - Add relevant untracked files to the staging area.\n - Create the commit with a message ending with:\n 🤖 Generated with [Claude Code](https://claude.ai/code)\n\n Co-Authored-By: Claude <noreply@anthropic.com>\n - Run git status to make sure the commit succeeded.\n4. If the commit fails due to pre-commit hook changes, retry the commit ONCE to include these automated changes. If it fails again, it usually means a pre-commit hook is preventing the commit. If the commit succeeds but you notice that files were modified by the pre-commit hook, you MUST amend your commit to include them.\n\nImportant notes:\n- NEVER update the git config\n- NEVER run additional commands to read or explore code, besides git bash commands\n- NEVER use the TodoWrite or Task tools\n- DO NOT push to the remote repository unless the user explicitly asks you to do so\n- IMPORTANT: Never use git commands with the -i flag (like git rebase -i or git add -i) since they require interactive input which is not supported.\n- If there are no changes to commit (i.e., no untracked files and no modifications), do not create an empty commit\n- In order to ensure good formatting, ALWAYS pass the commit message via a HEREDOC, a la this example:\n<example>\ngit commit -m \"$(cat <<'EOF'\n Commit message here.\n\n 🤖 Generated with [Claude Code](https://claude.ai/code)\n\n Co-Authored-By: Claude <noreply@anthropic.com>\n EOF\n )\"\n</example>\n\n# Creating pull requests\nUse the gh command via the Bash tool for ALL GitHub-related tasks including working with issues, pull requests, checks, and releases. If given a Github URL use the gh command to get the information needed.\n\nIMPORTANT: When the user asks you to create a pull request, follow these steps carefully:\n\n1. You have the capability to call multiple tools in a single response. When multiple independent pieces of information are requested, batch your tool calls together for optimal performance. ALWAYS run the following bash commands in parallel using the Bash tool, in order to understand the current state of the branch since it diverged from the main branch:\n - Run a git status command to see all untracked files\n - Run a git diff command to see both staged and unstaged changes that will be committed\n - Check if the current branch tracks a remote branch and is up to date with the remote, so you know if you need to push to the remote\n - Run a git log command and `git diff [base-branch]...HEAD` to understand the full commit history for the current branch (from the time it diverged from the base branch)\n2. Analyze all changes that will be included in the pull request, making sure to look at all relevant commits (NOT just the latest commit, but ALL commits that will be included in the pull request!!!), and draft a pull request summary\n3. You have the capability to call multiple tools in a single response. When multiple independent pieces of information are requested, batch your tool calls together for optimal performance. ALWAYS run the following commands in parallel:\n - Create new branch if needed\n - Push to remote with -u flag if needed\n - Create PR using gh pr create with the format below. Use a HEREDOC to pass the body to ensure correct formatting.\n<example>\ngh pr create --title \"the pr title\" --body \"$(cat <<'EOF'\n## Summary\n<1-3 bullet points>\n\n## Test plan\n[Checklist of TODOs for testing the pull request...]\n\n🤖 Generated with [Claude Code](https://claude.ai/code)\nEOF\n)\"\n</example>\n\nImportant:\n- NEVER update the git config\n- DO NOT use the TodoWrite or Task tools\n- Return the PR URL when you're done, so the user can see it\n\n# Other common operations\n- View comments on a Github PR: gh api repos/foo/bar/pulls/123/comments","input_schema":{"type":"object","$schema":"http://json-schema.org/draft-07/schema#","required":["command"],"properties":{"command":{"type":"string","description":"The command to execute"},"timeout":{"type":"number","description":"Optional timeout in milliseconds (max 300000)"},"description":{"type":"string","description":" Clear, concise description of what this command does in 5-10 words.

Complex multi-step tasks - When a task requires 3 or more distinct steps or actions\n2. Non-trivial and complex tasks - Tasks that require careful planning or multiple operations\n3. User explicitly requests todo list - When the user directly asks you to use the todo list\n4. User provides multiple tasks - When users provide a list of things to be done (numbered or comma-separated)\n5. After receiving new instructions - Immediately capture user requirements as todos\n6. When you start working on a task - Mark it as in_progress BEFORE beginning work. Ideally you should only have one todo as in_progress at a time\n7. After completing a task - Mark it as completed and add any new follow-up tasks discovered during implementation\n\n## When NOT to Use This Tool\n\nSkip using this tool when:\n1. There is only a single, straightforward task\n2. The task is trivial and tracking it provides no organizational benefit\n3. The task can be completed in less than 3 trivial steps\n4. The task is purely conversational or informational\n\nNOTE that you should not use this tool if there is only one trivial task to do. In this case you are better off just doing the task directly.\n\n## Examples of When to Use the Todo List\n\n<example>\nUser: I want to add a dark mode toggle to the application settings. Make sure you run the tests and build when you're done!\nAssistant: I'll help add a dark mode toggle to your application settings. Let me create a todo list to track this implementation.\n*Creates todo list with the following items:*\n1. Create dark mode toggle component in Settings page\n2. Add dark mode state management (context/store)\n3. Implement CSS-in-JS styles for dark theme\n4. Update existing components to support theme switching\n5. Run tests and build process, addressing any failures or errors that occur\n*Begins working on the first task*\n\n<reasoning>\nThe assistant used the todo list because:\n1. Adding dark mode is a multi-step feature requiring UI, state management, and styling changes\n2. The user explicitly requested tests and build be run afterward\n3. The assistant inferred that tests and build need to pass by adding \"Ensure tests and build succeed\" as the final task\n</reasoning>\n</example>\n\n<example>\nUser: Help me rename the function getCwd to getCurrentWorkingDirectory across my project\nAssistant: Let me first search through your codebase to find all occurrences of 'getCwd'.\n*Uses grep or search tools to locate all instances of getCwd in the codebase*\nAssistant: I've found 15 instances of 'getCwd' across 8 different files. Let me create a todo list to track these changes.\n*Creates todo list with specific items for each file that needs updating*\n\n<reasoning>\nThe assistant used the todo list because:\n1. First, the assistant searched to understand the scope of the task\n2. Upon finding multiple occurrences across different files, it determined this was a complex task with multiple steps\n3. The todo list helps ensure every instance is tracked and updated systematically\n4. This approach prevents missing any occurrences and maintains code consistency\n</reasoning>\n</example>\n\n\n<example>\nUser: I need to implement these features for my e-commerce site: user registration, product catalog, shopping cart, and checkout flow.\nAssistant: I'll help implement these features. First, let's add all the features to the todo list.\n*Creates a todo list breaking down each feature into specific tasks based on the project architecture*\nAssistant: Let's start with user registration. This will involve creating database models, API endpoints, and frontend forms that integrate with your existing authentication system.\n\n<reasoning>\nThe assistant used the todo list because:\n1. The user provided multiple complex features to implement in a comma separated list\n2. The todo list helps organize these large features into manageable tasks\n3. This approach allows for tracking progress across the entire implementation\n</reasoning>\n</example>\n\n<example>\nUser: Can you help optimize my React application? It's rendering slowly and has performance issues.</user>\nAssistant: I'll help optimize your React application. First, let me examine your codebase to identify potential performance bottlenecks.\n*Reviews component structure, render patterns, state management, and data fetching*\nAssistant: After analyzing your codebase, I've identified several performance issues. Let me create a todo list to track our optimization efforts.\n*Creates todo list with items like: 1) Implement memoization for expensive calculations in ProductList, 2) Add virtualization for long lists in Dashboard, 3) Optimize image loading in Gallery component, 4) Fix state update loops in ShoppingCart, 5) Review bundle size and implement code splitting*\nLet's start by implementing memoization for the expensive calculations in your ProductList component.</assistant>\n\n<reasoning>\nThe assistant used the todo list because:\n1. First, the assistant examined the codebase to identify specific performance issues\n2. Based on this analysis, it identified multiple optimization opportunities\n3. Performance optimization is a non-trivial task requiring multiple steps\n4. The todo list helps methodically track improvements across different components\n5. This systematic approach ensures all performance bottlenecks are addressed\n</reasoning>\n</example>\n\n## Examples of When NOT to Use the Todo List\n\n<example>\nUser: How do I print 'Hello World' in Python?\nAssistant: In Python, you can print \"Hello World\" with this simple code:\n\npython\nprint(\"Hello World\")\n\nThis will output the text \"Hello World\" to the console when executed.</assistant>\n\n<reasoning>\nThe assistant did not use the todo list because this is a single, trivial task that can be completed in one step. There's no need to track multiple tasks or steps for such a straightforward request.\n</reasoning>\n</example>\n\n<example>\nUser: What does the git status command do?\nAssistant: The git status command shows the current state of your working directory and staging area. It displays which changes have been staged, which haven't, and which files aren't being tracked by Git. This is a fundamental command for understanding the current state of your repository before making commits.\n\n<reasoning>\nThe assistant did not use the todo list because this is an informational request with no actual coding task to complete. The user is simply asking for an explanation, not for the assistant to perform multiple steps or tasks.\n</reasoning>\n</example>\n\n<example>\nUser: Can you add a comment to the calculateTotal function to explain what it does?\nAssistant: Sure, let me add a comment to the calculateTotal function to explain what it does.\n* Uses the Edit tool to add a comment to the calculateTotal function *\n\n<reasoning>\nThe assistant did not use the todo list because this is a single, straightforward task confined to one location in the code. Adding a comment doesn't require tracking multiple steps or systematic organization.\n</reasoning>\n</example>\n\n<example>\nUser: Run npm install for me and tell me what happens.\nAssistant: I'll run the npm install command for you.\n\n*Executes: npm install*\n\nThe command completed successfully. Here's the output:\n[Output of npm install command]\n\nAll dependencies have been installed according to your package.json file.\n\n<reasoning>\nThe assistant did not use the todo list because this is a single command execution with immediate results.

Built with Bun and Hono framework, deployed as separate Docker images for each service.\n\n## Architectural Decision Records (ADRs)\n\nTechnical decisions are documented in `docs/ADRs/`. Key architectural decisions:\n\n- **ADR-012**: Database Schema Evolution Strategy - TypeScript migrations with init SQL\n- **ADR-013**: TypeScript Project References - Monorepo type checking solution\n- **ADR-016**: MCP Server Implementation - Model Context Protocol server architecture (superseded)\n- **ADR-017**: MCP Prompt Sharing - Current implementation for prompt sharing via MCP\n- **ADR-018**: AI-Powered Conversation Analysis - Background job architecture for AI analysis\n\n**AI Assistant Directive**: When discussing architecture or making technical decisions, always reference relevant ADRs. If a new architectural decision is made during development, create or update an ADR to document it. This ensures all technical decisions have clear rationale and can be revisited if needed.\n\n## Architecture\n\n### Monorepo Structure\n\n```\nclaude-nexus-proxy/\n├── packages/shared/ # Shared types and configurations\n├── services/\n│ ├── proxy/ # Proxy API service (Port 3000)\n│ └── dashboard/ # Dashboard web service (Port 3001)\n├── scripts/ # Utility scripts\n├── docker/ # Docker configurations\n│ ├── proxy/ # Proxy Dockerfile\n│ └── dashboard/ # Dashboard Dockerfile\n├── docker-compose.yml # Container orchestration\n├── .env # Proxy/Dashboard configuration\n└── credentials/ # Domain credentials (Claude Auth, Slack, ...)\n\n\n```\n\n### Key Services\n\n**Proxy Service** (`services/proxy/`)\n\n- Direct API forwarding to Claude\n- Multi-auth support (API keys, OAuth with auto-refresh)\n- Token tracking and telemetry\n- Request/response storage\n- Slack notifications\n- AI-powered conversation analysis (Phase 2 - Prompt Engineering with full env var support)\n\n**Dashboard Service** (`services/dashboard/`)\n\n- Monitoring UI\n- Analytics and usage charts\n- Request history browser\n- SSE for live updates\n\n## Development\n\n```bash\n# Install dependencies\nbun install\n\n# Run both services\nbun run dev\n\n# Run individually\nbun run dev:proxy # Port 3000\nbun run dev:dashboard # Port 3001\n\n# Build\nbun run build\n```\n\n### Git Pre-commit Hooks\n\nThe project uses Husky and lint-staged for automated code quality checks:\n\n```bash\n# Pre-commit hooks are automatically installed via postinstall script\nbun install\n\n# Manual hook installation (if needed)\nbunx husky init\n```\n\n**Pre-commit checks:**\n\n- ESLint fixes for TypeScript/JavaScript files\n- Prettier formatting for all supported file types\n- Automatic fixes are applied when possible\n\n**Note:** TypeScript type checking is not included in pre-commit hooks for performance reasons. Type checking runs in CI/CD pipeline.\n\n## Docker Deployment\n\nThe project uses **separate Docker images** for each service:\n\n```bash\n# Build images\n./docker/build-images.sh\n\n# Run proxy service\ndocker run -p 3000:3000 alanpurestake/claude-nexus-proxy:latest\n\n# Run dashboard service\ndocker run -p 3001:3001 alanpurestake/claude-nexus-dashboard:latest\n```\n\nDocker configurations are in the `docker/` directory. Each service has its own optimized image for better security, scaling, and maintainability.\n\n### Docker Compose Environment\n\ndocker/docker-compose.yml: Postgres + Proxy + Dashboard + Claude CLI (with ccusage and token monitoring). `./docker-up.sh` script is used instead of `docker compose -f ...` to ensure `.env` is loaded properly.\n\n```bash\n# Build the local images\n./docker-up.sh build\n\n# Run the full environment (requires real Claude account in )\n./docker-up.sh up -d\n\n# Run a claude query\n./docker-up.sh exec claude-cli claude \"hi\"\n\n# Run usage monitor for real-time tracking\n./docker-up.sh exec claude-cli monitor\n\n# Check daily usage stats\n./docker-up.sh exec claude-cli ccusage daily\n```\n\n## Key Implementation Details\n\n### Request Timeout Configuration\n\nThe proxy supports long-running Claude API requests with configurable timeouts:\n\n- **Default timeout**: 10 minutes (600,000ms) for Claude API requests\n- **Server timeout**: 11 minutes (660,000ms) to prevent premature connection closure\n- **Retry timeout**: Slightly longer than request timeout to allow for retries\n- Configure via `CLAUDE_API_TIMEOUT` and `PROXY_SERVER_TIMEOUT` environment variables\n\n### Conversation Tracking & Branching\n\nThe proxy automatically tracks conversations and detects branches using message hashing:\n\n**How it works:**\n\n1. Each message in a request is hashed using SHA-256\n2. The current message hash and parent message hash (previous message) are stored\n3. Requests are linked into conversations by matching parent/child relationships\n4. Conversations support branching (like git) when resumed from earlier points\n5. Branches are automatically detected when multiple requests share the same parent\n6. When multiple conversations have the same parent hash, the system picks the conversation with the fewest requests to continue\n7. Messages continue on the same branch as their parent unless they create a new branch point\n\n**Message Normalization:**\n\n- String content and array content are normalized to produce consistent hashes\n- Example: `\"hello\"` and `[{type: \"text\", text: \"hello\"}]` produce the same hash\n- **System reminders are filtered out**: Content items starting with `<system-reminder>` are ignored during hashing\n- **Duplicate messages are deduplicated**: When tool_use or tool_result messages have duplicate IDs, only the first occurrence is included in the hash\n- This ensures conversations link correctly regardless of content format, system reminder presence, or duplicate messages from the Claude API\n\n**Dual Hash System:**\n\n- **Message Hash**: Used for conversation linking, contains only message content\n- **System Hash**: Tracks system prompt separately, stored in `system_hash` column\n- This allows conversations to maintain links even when system prompts change (e.g., git status updates, context compaction)\n- Backward compatible: Old conversations continue to work without modification\n\n**Special Conversation Handling:**\n\n- **Conversation Summarization**: When Claude summarizes a conversation (detected by system prompt \"You are a helpful AI assistant tasked with summarizing conversations\"), the system links to the previous conversation ignoring system prompt differences\n- **Compact Conversations**: When a conversation is continued from a previous one due to context overflow (first message starts with \"This session is being continued from a previous conversation...\"), it:\n - Links to the source conversation automatically\n - Creates a special branch ID format: `compact_HHMMSS`\n - Preserves the compact branch for all follow-up messages in that conversation\n - Prevents unnecessary branching when continuing compact conversations\n\n**API Endpoints:**\n\n- `/api/conversations` - Get conversations grouped by conversation_id with branch information\n- Query parameters: `domain` (filter by domain), `limit` (max conversations)\n\n**Database Schema:**\n\n- `conversation_id` - UUID identifying the conversation\n- `current_message_hash` - Hash of the last message in the request\n- `parent_message_hash` - Hash of the previous message (null for first message)\n- `system_hash` - Hash of the system prompt (for tracking context changes)\n- `branch_id` - Branch identifier (defaults to 'main', auto-generated for new branches)\n- `parent_request_id` - Direct link to the parent request in the conversation chain\n\n**Dashboard Features:**\n\n- **Conversations View** - Visual timeline showing message flow and branches\n- **Branch Visualization** - Blue nodes indicate branch points\n- **Branch Labels** - Non-main branches are labeled with their branch ID\n- **Conversation Grouping** - All related requests grouped under one conversation\n- **Multiple Tool Display** - Messages with multiple tool_use or tool_result blocks are properly displayed with visual separation (horizontal rules between each tool invocation)\n- **Duplicate Filtering** - Duplicate tool_use and tool_result blocks (same ID) are automatically filtered out\n- **System Reminder Filtering** - System reminder text blocks are hidden from display\n\n### Authentication Flow\n\n**Client Authentication (Proxy Level):**\n\n1. Extract domain from Host header\n2. Check for `client_api_key` in domain credential file\n3. Verify Bearer token against stored key using timing-safe comparison\n4. Return 401 Unauthorized if invalid\n\n**Claude API Authentication:**\n\n1. Check domain-specific credential files (`<domain>.credentials.json`)\n2. Use Authorization header from request\n\n### OAuth Support\n\n- Auto-refresh tokens 1 minute before expiry\n- Stores refreshed tokens back to credential files\n- Adds `anthropic-beta: oauth-2025-04-20` header\n\n### MCP (Model Context Protocol) Server\n\nThe proxy includes an MCP server for managing and serving prompts:\n\n**Features:**\n\n- File-based prompt storage using YAML files in `prompts/` directory\n- Prompts are named after their file name (e.g., `feature.yaml` becomes `/feature`)\n- Handlebars templating with `{{variable}}` syntax\n- Hot-reloading when files change\n- Optional GitHub repository synchronization\n\n**Configuration:**\n\n```bash\n# Basic MCP setup (file-based)\nMCP_ENABLED=true\nMCP_PROMPTS_DIR=./prompts\nMCP_WATCH_FILES=true\n\n# Optional GitHub sync\nMCP_GITHUB_OWNER=your-org\nMCP_GITHUB_REPO=prompt-library\nMCP_GITHUB_BRANCH=main\nMCP_GITHUB_TOKEN=ghp_xxxx\nMCP_GITHUB_PATH=prompts/\nMCP_SYNC_INTERVAL=300\n```\n\n**How it works:**\n\n- When only `MCP_ENABLED=true` is set, prompts are loaded from local YAML files\n- When GitHub credentials are configured, the system syncs from the repository\n- GitHub sync fetches prompts and writes them to the local filesystem\n- **Important**: GitHub sync only replaces files that exist in the repository, preserving local-only prompts\n- Files are validated to prevent path traversal security vulnerabilities\n- The PromptRegistryService loads prompts from files into memory\n- MCP protocol endpoints are available at `/mcp`\n\n**Prompt format:**\n\n```yaml\n# Note: The prompt name in Claude will be the file name (without .yaml extension)\n# For example, this file saved as 'my-feature.yaml' will be available as '/my-feature'\nname: My Prompt # This field is ignored - file name is used instead\ndescription: Description of the prompt\ntemplate: |\n You are {{role}}.\n {{#if context}}\n Context: {{context}}\n {{/if}}\n```\n\n**Using MCP with Claude Desktop:**\n\n1. **Install the MCP server in Claude Desktop**:\n\n ```bash\n claude mcp add nexus-prompts --scope user -- bunx -y mcp-remote@latest http://localhost:3000/mcp --header \"Authorization: Bearer YOUR_CLIENT_API_KEY\"\n ```\n\n2. **Replace YOUR_CLIENT_API_KEY** with the actual client API key from your domain's credential file (e.g., `cnp_live_...`)\n\n3. **Restart Claude Desktop** to load the MCP server\n\n4. **Available commands**:\n - Prompts will appear as slash commands in Claude (e.g., `/feature` for a prompt named `feature.yaml`)\n - Use tab completion to see available prompts\n\n**MCP Implementation Details:**\n\n- **Protocol Version**: Uses MCP protocol version `2024-11-05`\n- **Authentication**: Bearer token authentication via client API keys\n- **Endpoints**:\n - `POST /mcp` - Main MCP JSON-RPC endpoint\n - `GET /mcp` - Discovery endpoint\n- **Supported Methods**:\n - `initialize` - Protocol handshake\n - `prompts/list` - List available prompts\n - `prompts/get` - Get and render a specific prompt with variables\n\n### Token Tracking\n\n**In-Memory Tracking (Legacy)**\n\n- Per-domain statistics\n- Request type classification (query evaluation vs inference)\n- Tool call counting\n- Available at `/token-stats` endpoint\n\n**Comprehensive Token Usage Tracking (New)**\n\n- Tracks ALL request types (including query_evaluation and quota)\n- Persistent storage in partitioned `token_usage` table\n- 5-hour rolling window support for monitoring Claude API limits\n- Per-account AND per-domain tracking\n- API endpoints:\n - `/api/token-usage/current` - Current window usage\n - `/api/token-usage/daily` - Historical daily usage data\n - `/api/conversations` - Conversations with account info\n- **Note**: Rate limiting is handled by Claude API directly. The proxy only tracks and displays usage statistics.\n\n### Storage\n\n- PostgreSQL for request/response data\n- Write-only access from proxy\n- Read-only access from dashboard\n- Automatic batch processing\n- **Conversation Grouping**: Requests are automatically grouped by conversation using message hashing\n\n### Debug Logging\n\nWhen `DEBUG=true`:\n\n- Logs full request/response (with sensitive data masked)\n- Shows streaming chunks\n- Masks patterns: `sk-ant-****`, `Bearer ****`\n- Includes SQL query stack traces\n\n### SQL Query Logging\n\nEnable SQL query logging in debug mode:\n\n```bash\n# Option 1: Enable all debug logging (includes SQL)\nDEBUG=true bun run dev\n\n# Option 2: Enable only SQL query logging\nDEBUG_SQL=true bun run dev\n\n# Option 3: Set in .env file\nDEBUG_SQL=true\n```\n\nSQL logging features:\n\n- All queries with parameters\n- Query execution time\n- Row counts\n- Slow query warnings (default: >5 seconds)\n- Failed query errors with details\n\n## Environment Variables\n\n**Essential:**\n\n- `DATABASE_URL` - PostgreSQL connection\n- `DASHBOARD_API_KEY` - Dashboard authentication\n\n**Optional:**\n\n- `DEBUG` - Enable debug logging\n- `DEBUG_SQL` - Enable SQL query logging (default: false)\n- `STORAGE_ENABLED` - Enable storage (default: false)\n- `SLACK_WEBHOOK_URL` - Slack notifications\n- `CREDENTIALS_DIR` - Domain credential directory\n- `COLLECT_TEST_SAMPLES` - Collect request samples for testing (default: false)\n- `TEST_SAMPLES_DIR` - Directory for test samples (default: test-samples)\n- `ENABLE_CLIENT_AUTH` - Enable client API key authentication (default: true). Set to false to allow anyone to use the proxy without authentication\n- `DASHBOARD_CACHE_TTL` - Dashboard cache TTL in seconds (default: 30). Set to 0 to disable caching\n- `SLOW_QUERY_THRESHOLD_MS` - Threshold in milliseconds for logging slow SQL queries (default: 5000)\n- `CLAUDE_API_TIMEOUT` - Timeout for Claude API requests in milliseconds (default: 600000 / 10 minutes)\n- `PROXY_SERVER_TIMEOUT` - Server-level timeout in milliseconds (default: 660000 / 11 minutes)\n- `STORAGE_ADAPTER_CLEANUP_MS` - Interval for cleaning up orphaned request ID mappings in milliseconds (default: 300000 / 5 minutes)\n- `STORAGE_ADAPTER_RETENTION_MS` - Retention time for request ID mappings in milliseconds (default: 3600000 / 1 hour)\n- `API_KEY_SALT` - Salt for hashing API keys in database (default: 'claude-nexus-proxy-default-salt')\n- `SPARK_API_URL` - Spark API base URL for recommendation feedback (default: 'http://localhost:8000')\n- `SPARK_API_KEY` - API key for authenticating with Spark API\n\n## Important Notes\n\n### Request Metadata\n\n- Query evaluation and quota are not part of the conversation, they serve as metadata queries\n\n## Testing & Type Safety\n\n**Type Checking:**\n\n- Run `bun run typecheck` before committing\n- Type checking is automatic during builds\n- Fix all type errors before deploying\n- **TypeScript Project References**: The monorepo uses TypeScript Project References for proper dependency management\n - Automatically handles build order between packages\n - Generates declaration files for cross-package imports\n - Run `tsc --build` at the root to type check all packages\n - See ADR-013 for details on this architectural decision\n\n**Test Sample Collection:**\nThe proxy can collect real request samples for test development:\n\n- Enable with `COLLECT_TEST_SAMPLES=true`\n- Samples are stored in `test-samples/` directory\n- Each request type gets its own file (e.g., `inference_streaming_opus.json`)\n- Sensitive data is automatically masked\n- Samples include headers, body, and metadata\n\n**Tests:**\n\nThe project includes comprehensive tests for conversation and subtask linking:\n\n- **Conversation Linking Tests**: `packages/shared/src/utils/__tests__/conversation-linker.test.ts`\n - Tests message hashing, branch detection, and conversation linking\n - Includes JSON fixture tests for real-world scenarios\n - Tests integrated subtask detection within ConversationLinker\n\n- **Subtask Detection Tests**: `packages/shared/src/utils/__tests__/subtask-detection.test.ts`\n - Tests complete subtask detection logic in ConversationLinker\n - Validates TaskContext handling and invocation matching\n - Tests conversation inheritance and branch naming\n - Covers edge cases like multi-message conversations\n\n- **Subtask Linking Simulation**: `packages/shared/src/utils/__tests__/subtask-linker.test.ts`\n - Simulates the old two-phase subtask detection (for reference)\n - Tests Task tool invocation matching\n - Validates time window enforcement\n - Includes JSON fixtures for various subtask scenarios\n\nRun tests with:\n\n```bash\n# All tests\nbun test\n\n# Specific package\ncd packages/shared && bun test\n\n# Specific test file\nbun test conversation-linker.test.ts\n```\n\n## Important Notes\n\n- Uses Bun runtime exclusively (no Node.js)\n- Separate Docker images for each service\n- TypeScript compilation for production builds\n- Model-agnostic (accepts any model name)\n\n## Database Schema\n\n### Main Tables\n\n**api_requests** - Stores all API requests and responses with token tracking:\n\n- `account_id` - Account identifier from credential files for per-account tracking\n- `input_tokens`, `output_tokens`, `total_tokens` - Token usage metrics\n- `conversation_id`, `branch_id` - Conversation tracking\n- `current_message_hash`, `parent_message_hash` - Message linking\n- `parent_task_request_id`, `is_subtask`, `task_tool_invocation` - Sub-task tracking\n\n**streaming_chunks** - Stores streaming response chunks\n\n### Account-Based Token Tracking\n\nToken usage is tracked directly in the `api_requests` table:\n\n- Each request is associated with an `account_id` from the credential file\n- Token counts are stored per request for accurate tracking\n- Queries aggregate usage by account and time window\n\n### Database Schema Evolution\n\n**Schema Management:**\n\n- Initial schema: `scripts/init-database.sql`\n- Migrations: `scripts/db/migrations/` (TypeScript files)\n- Auto-initialization: `writer.ts` uses init SQL file when tables don't exist\n\n**Running Migrations:**\n\n```bash\n# Run a specific migration\nbun run scripts/db/migrations/001-add-conversation-tracking.ts\n\n# Run all migrations in order\nfor file in scripts/db/migrations/*.ts; do bun run \"$file\"; done\n```\n\n**Available Migrations:**\n\n- 000: Initial database setup\n- 001: Add conversation tracking\n- 002: Optimize conversation indexes\n- 003: Add sub-task tracking\n- 004: Optimize window function queries\n- 005: Populate account IDs\n- 006: Split conversation hashes\n- 007: Add parent_request_id\n- 008: Update subtask conversation IDs and optimize Task queries\n\nSee `docs/04-Architecture/ADRs/adr-012-database-schema-evolution.md` for details.\n\n## Common Tasks\n\n### Add Domain Credentials\n\n```bash\n# Generate secure client API key\nbun run scripts/generate-api-key.ts\n\n# Create credential file\ncat > credentials/domain.com.credentials.json << EOF\n{\n \"type\": \"api_key\",\n \"accountId\": \"acc_f9e1c2d3b4a5\", # Unique account identifier\n \"api_key\": \"sk-ant-...\",\n \"client_api_key\": \"cnp_live_...\"\n}\nEOF\n```\n\n### Enable Storage\n\n```bash\nexport STORAGE_ENABLED=true\nexport DATABASE_URL=postgresql://...\n```\n\n### View Token Stats\n\n```bash\ncurl http://localhost:3000/token-stats\n```\n\n### Access Dashboard\n\n```bash\nopen http://localhost:3001\n# Use DASHBOARD_API_KEY for authentication\n# Auth header: X-Dashboard-Key: <your-key>\n```\n\n## Sub-task Tracking & Visualization\n\n### Sub-task Detection\n\nThe proxy automatically detects and tracks sub-tasks spawned using the Task tool through an integrated single-phase process:\n\n**Single-Phase Detection (ConversationLinker):**\n\n- Complete subtask detection happens within ConversationLinker using the SubtaskQueryExecutor pattern\n- SQL queries retrieve Task invocations from database (24-hour window)\n- Matches single-message user conversations against recent Task invocations (30-second window)\n- Sets `is_subtask=true` and links to parent via `parent_task_request_id`\n- Subtasks inherit parent's conversation_id with unique branch naming (subtask_1, subtask_2, etc.)\n\n**Architecture Components:**\n\n- **SubtaskQueryExecutor**: Injected function that queries for Task tool invocations\n- **ConversationLinker**: Central component handling all conversation and subtask linking logic\n- **Optimized SQL Queries**: Uses PostgreSQL `@>` containment operator for exact prompt matching\n- **RequestByIdExecutor**: Fetches parent task details for conversation inheritance\n- **GIN Index**: Full JSONB index on response_body for efficient containment queries\n\n**Query Optimization:**\n\nWhen the subtask prompt is known, the system uses an optimized query:\n\n```sql\nresponse_body @> jsonb_build_object(\n 'content', jsonb_build_array(\n jsonb_build_object(\n 'type', 'tool_use',\n 'name', 'Task',\n 'input', jsonb_build_object('prompt', $4::text)\n )\n )\n)\n```\n\nThis leverages the GIN index for O(log n) lookup performance instead of scanning all Task invocations.\n\n**Database Fields:**\n\n- `parent_task_request_id` - Links sub-task requests to their parent task\n- `is_subtask` - Boolean flag indicating if a request is a confirmed sub-task\n- `task_tool_invocation` - JSONB array storing Task tool invocations (for historical queries)\n\n**Sub-task Linking:**\n\n- Sub-tasks are linked by exact matching of user message to Task tool invocation prompts\n- The system creates parent-child relationships between tasks and their sub-tasks\n- Multiple sub-tasks can be spawned from a single parent request\n- Sub-tasks inherit parent task's conversation_id with sequential branch IDs (subtask_1, subtask_2, etc.)\n\n### Dashboard Visualization\n\n**Conversation Tree:**\n\n- Sub-task nodes appear as separate gray boxes to the right of parent nodes\n- Format: \"sub-task N (M)\" where N is the sub-task number and M is the message count\n- Sub-task boxes are clickable and link to their conversation\n- Hover over sub-task boxes to see the task prompt in a tooltip\n\n**Stats Display:**\n\n- \"Total Sub-tasks\" panel shows count of all sub-tasks in a conversation\n- Sub-task indicators on parent nodes show number of spawned tasks\n\n**Visual Design:**\n\n- Sub-task boxes: 100x36px gray boxes with 150px right offset\n- Tooltips: 250x130px with gradient background, appear above nodes on hover\n- Connected to parent nodes with horizontal edges\n\n## Important Implementation Notes\n\n### Conversation Hash Filtering\n\nWhen generating message hashes for conversation tracking, the system filters out:\n\n- Content items that start with `<system-reminder>`\n- This prevents conversation linking from breaking when Claude adds system reminders\n\n### Dashboard Authentication\n\n- Uses `X-Dashboard-Key` header (not Authorization)\n- Cookie-based auth also supported for browser sessions\n\n### AI-Powered Conversation Analysis\n\nThe proxy supports automated analysis of conversations using AI models (currently Gemini 1.5 Flash or 2.5 Pro):\n\n**Features:**\n\n- Background processing of conversations for insights\n- Status tracking (pending, processing, completed, failed)\n- Token usage tracking for cost management\n- Retry logic with exponential backoff\n- Unique analyses per conversation and branch\n- Comprehensive environment variable configuration for prompt tuning\n- Graceful handling of unparseable JSON responses\n- Automatic failure of jobs exceeding max retries\n- Custom prompt support for targeted analysis\n\n**Error Handling:**\n\n- **JSON Parse Failures**: When the AI model returns malformed JSON, the system stores the raw text response instead of failing\n- **Max Retry Exceeded**: Jobs that exceed `AI_ANALYSIS_MAX_RETRIES` are automatically marked as failed with clear error messages\n- **Non-retryable Errors**: Sensitive information detection and API key issues fail immediately without retries\n\n**Database Schema:**\n\n- `conversation_analyses` table stores analysis results\n- ENUM type for status field ensures data integrity\n- Automatic `updated_at` timestamp via trigger\n- Partial index on pending status for efficient queue processing\n- Supports both structured data (`analysis_data`) and raw text (`analysis_content`)\n\n**API Endpoints:**\n\n- `POST /api/analyses` - Create analysis request (supports `customPrompt`)\n- `GET /api/analyses/:conversationId/:branchId` - Get analysis status/result\n- `POST /api/analyses/:conversationId/:branchId/regenerate` - Force regeneration with optional custom prompt\n\n**Utility Scripts:**\n\n- `scripts/check-analysis-jobs.ts` - Check status of analysis jobs\n- `scripts/check-ai-worker-config.ts` - Verify AI worker configuration\n- `scripts/reset-stuck-analysis-jobs.ts` - Reset jobs stuck with high retry counts\n- `scripts/fail-exceeded-retry-jobs.ts` - Manually fail jobs exceeding max retries\n- `scripts/check-analysis-content.ts` - Inspect analysis content for a conversation\n\n**Implementation Status:**\n\n- ✅ Database schema (Migration 011, 012)\n- ✅ API endpoints with custom prompt support\n- ✅ Prompt engineering with actionable feedback\n- ✅ Background worker with resilient error handling\n- ✅ Dashboard UI with analysis panel\n- ✅ Graceful JSON parse failure handling\n- ✅ Automatic max retry failure\n\nSee [ADR-016](docs/04-Architecture/ADRs/adr-016-ai-powered-conversation-analysis.md) for architectural decisions.\n\n**Background Worker Configuration:**\n\nEnable the AI Analysis background worker by setting these environment variables:\n\n```bash\n# Enable the worker\nAI_WORKER_ENABLED=true\n\n# Worker configuration\nAI_WORKER_POLL_INTERVAL_MS=5000 # Poll every 5 seconds\nAI_WORKER_MAX_CONCURRENT_JOBS=3 # Process up to 3 jobs concurrently\nAI_WORKER_JOB_TIMEOUT_MINUTES=5 # Mark jobs as stuck after 5 minutes\n\n# Resilience configuration\nAI_ANALYSIS_MAX_RETRIES=3 # Retry failed jobs up to 3 times\nAI_ANALYSIS_GEMINI_REQUEST_TIMEOUT_MS=60000 # Gemini API request timeout\n\n# Gemini API configuration\nGEMINI_API_KEY=your-api-key-here\nGEMINI_API_URL=https://generativelanguage.googleapis.com/v1beta/models\nGEMINI_MODEL_NAME=gemini-2.0-flash-exp\n\n# Prompt engineering configuration (optional)\nAI_MAX_PROMPT_TOKENS=855000 # Override calculated token limit\nAI_HEAD_MESSAGES=10 # Messages to keep from start\nAI_TAIL_MESSAGES=30 # Messages to keep from end\n\n# Analysis token limits\nAI_ANALYSIS_INPUT_TRUNCATION_TARGET_TOKENS=8192 # Target token count for input message truncation\nAI_ANALYSIS_TRUNCATE_FIRST_N_TOKENS=1000 # Tokens from conversation start\nAI_ANALYSIS_TRUNCATE_LAST_M_TOKENS=4000 # Tokens from conversation end\n```\n\nThe worker runs in-process with the proxy service and uses PostgreSQL row-level locking to safely process jobs across multiple instances.\n\n### Spark Tool Integration\n\nThe dashboard supports the Spark recommendation tool (`mcp__spark__get_recommendation`):\n\n**Features:**\n\n- Automatic detection of Spark tool usage in conversations\n- Display of recommendations in a formatted view\n- Feedback UI for rating and commenting on recommendations\n- Batch fetching of existing feedback\n- Integration with Spark API for feedback submission\n\n**Configuration:**\n\n1. Set `SPARK_API_URL` and `SPARK_API_KEY` environment variables\n2. The dashboard will automatically detect Spark recommendations in tool_result messages\n3. Users can submit feedback directly from the request details page\n4. The proxy logs Spark configuration at startup:\n - When configured: Shows URL and confirms API key is set\n - When not configured: Shows \"SPARK_API_KEY not set\"\n\n**API Endpoints:**\n\n- `POST /api/spark/feedback` - Submit feedback for a recommendation\n- `GET /api/spark/sessions/:sessionId/feedback` - Get feedback for a specific session\n- `POST /api/spark/feedback/batch` - Get feedback for multiple sessions\n\n**Security Note:**\n\nThe dashboard authentication cookie (`dashboard_auth`) is set with `httpOnly: false` to allow JavaScript access for making authenticated API calls from the browser to the proxy service. This is a security trade-off that enables the inline feedback component to work. Consider implementing a more secure approach such as:\n\n- Using a separate API token for browser-based requests\n- Implementing a server-side proxy endpoint in the dashboard\n- Using session-based authentication with CSRF tokens\n\n### SQL Query Optimization\n\n- Always include all required fields in SELECT statements\n- Missing fields like `parent_task_request_id`, `is_subtask`, `task_tool_invocation` will break sub-task tracking\n- Use the SLOW_QUERY_THRESHOLD_MS env var to monitor query performance\n\n### Check Token Usage\n\n```bash\n# Current 5-hour window usage\ncurl \"http://localhost:3000/api/token-usage/current?accountId=acc_f9e1c2d3b4a5&window=300\" \\\n -H \"X-Dashboard-Key: $DASHBOARD_API_KEY\"\n\n# Daily usage (last 30 days)\ncurl \"http://localhost:3000/api/token-usage/daily?accountId=acc_f9e1c2d3b4a5&aggregate=true\" \\\n -H \"X-Dashboard-Key: $DASHBOARD_API_KEY\"\n\n# View conversations\ncurl \"http://localhost:3000/api/conversations?accountId=acc_f9e1c2d3b4a5\" \\\n -H \"X-Dashboard-Key: $DASHBOARD_API_KEY\"\n```\n\n### Copy Conversation Between Databases\n\n```bash\n# Copy a conversation from one database to another\nbun run db:copy-conversation --conversation-id <uuid> --dest-db <url> [options]\n\n# Example: Copy to staging database (same table names)\nbun run db:copy-conversation --conversation-id 123e4567-e89b-12d3-a456-426614174000 \\\n --dest-db \"postgresql://user:pass@staging-host:5432/staging_db\"\n\n# Dry run to preview what would be copied\nbun run db:copy-conversation --conversation-id 123e4567-e89b-12d3-a456-426614174000 \\\n --dest-db \"postgresql://user:pass@staging-host:5432/staging_db\" --dry-run\n\n# Copy with streaming chunks\nbun run db:copy-conversation --conversation-id 123e4567-e89b-12d3-a456-426614174000 \\\n --dest-db \"postgresql://user:pass@staging-host:5432/staging_db\" --include-chunks\n\n# Use custom table names (e.g., from api_requests to api_requests_backup)\nbun run db:copy-conversation --conversation-id 123e4567-e89b-12d3-a456-426614174000 \\\n --dest-db \"postgresql://user:pass@staging-host:5432/staging_db\" \\\n --source-table api_requests --dest-table api_requests_backup\n```\n\n## Maintenance\n\n### Grooming\n\nThe process of `grooming` is used to keep a clean repository.

Let me start with creating an ADR documenting this decision:","type":"text"},{"id":"toolu_01MuaQ7JmWcptGbBDZokeSmw","name":"Write","type":"tool_use","input":{"content":"# ADR-019: Dashboard Read-Only Mode Security Implications\n\n## Status\n\nAccepted\n\n## Context\n\nThe Claude Nexus Proxy dashboard was modified to support a \"read-only mode\" that allows access without authentication when `DASHBOARD_API_KEY` is not set. This was implemented to simplify development and quick deployments, but it introduces significant security concerns that need to be documented and addressed.\n\n### Current Implementation\n\nWhen `DASHBOARD_API_KEY` is not set in the environment:\n- The dashboard operates in \"read-only mode\" (`isReadOnly = true`)\n- All authentication checks are bypassed\n- Anyone with network access to the dashboard can view all data\n- This includes sensitive information such as:\n - All API requests and responses\n - Conversation histories with potentially sensitive content\n - Token usage statistics and costs\n - Account identifiers and usage patterns\n - AI analysis results and insights\n\n## Decision Drivers\n\n- **Developer Experience**: Need for quick local development without authentication setup\n- **Security**: Protecting sensitive conversation data and usage information\n- **Deployment Safety**: Preventing accidental exposure of data in production\n- **Transparency**: Clear communication about security implications\n- **Backward Compatibility**: Supporting existing deployments that rely on read-only mode\n\n## Considered Options\n\n1. **Remove Read-Only Mode Entirely**\n - Description: Require `DASHBOARD_API_KEY` in all cases\n - Pros: \n - Eliminates security risk completely\n - Forces secure configuration\n - Simpler security model\n - Cons: \n - Breaks existing deployments\n - Complicates local development\n - More setup friction\n\n2. **Keep Read-Only Mode with Clear Warnings**\n - Description: Maintain current behavior but add prominent security warnings\n - Pros:\n - Preserves backward compatibility\n - Maintains developer convenience\n - Clear about security implications\n - Cons:\n - Security risk remains\n - Users may ignore warnings\n - Potential for misconfiguration\n\n3. **Read-Only Mode for Local Development Only**\n - Description: Enable read-only mode only when explicitly running in development mode\n - Pros:\n - Balances security and convenience\n - Safe by default in production\n - Developer-friendly\n - Cons:\n - Requires additional configuration\n - May confuse users about when auth is required\n\n4. **Implement IP-Based Restrictions for Read-Only Mode**\n - Description: Allow read-only mode but restrict to localhost/private IPs\n - Pros:\n - Safer than unrestricted access\n - Still convenient for local development\n - Cons:\n - Can be bypassed with proxies\n - Complex to implement correctly\n - False sense of security\n\n## Decision\n\nWe will **keep read-only mode with clear warnings** (Option 2) for now, but with the following immediate actions:\n\n1. Add prominent security warnings in all documentation\n2. Display security warnings in the dashboard UI when in read-only mode\n3. Log warnings at startup when read-only mode is active\n4. Plan for deprecation in a future major version\n\n### Implementation Details\n\n1. **Documentation Updates**:\n - Add security warnings to README.md\n - Update CLAUDE.md with security implications\n - Enhance security.md with detailed warnings\n - Add warnings to deployment guides\n\n2. **UI Warnings**:\n ```typescript\n // Display banner when in read-only mode\n if (isReadOnly) {\n showWarningBanner('Dashboard is in read-only mode without authentication. Do not use in production!')\n }\n ```\n\n3. **Startup Warnings**:\n ```typescript\n if (!process.env.DASHBOARD_API_KEY) {\n console.warn('⚠️ WARNING: Dashboard running in READ-ONLY MODE without authentication!')\n console.warn('⚠️ This exposes all conversation data to anyone with network access.')\n console.warn('⚠️ Set DASHBOARD_API_KEY environment variable to enable authentication.')\n }\n ```\n\n## Consequences\n\n### Positive\n\n- Maintains backward compatibility\n- Preserves developer convenience for local development\n- Clear communication reduces risk of accidental exposure\n- Provides migration path for existing users\n\n### Negative\n\n- Security vulnerability remains until deprecated\n- Risk of users ignoring warnings\n- Potential for data exposure if deployed incorrectly\n- Technical debt that needs future resolution\n\n### Security Implications\n\n**Critical**: Running the dashboard without `DASHBOARD_API_KEY` exposes:\n- All conversation histories\n- Token usage and costs\n- Account information\n- AI analysis results\n- Request/response payloads\n\nThis mode should **NEVER** be used in production or any environment accessible from the internet.\n\n## Future Recommendations\n\n1. **Phase 1** (Current): Add warnings and documentation\n2. **Phase 2** (Next Minor Version): Add deprecation warnings\n3. **Phase 3** (Next Major Version): Remove read-only mode or restrict to explicit development mode\n4. **Alternative**: Implement a separate \"demo mode\" with synthetic data for testing\n\n## References\n\n- [Security Guide](../../03-Operations/security.md)\n- [Dashboard Architecture (ADR-009)](./adr-009-dashboard-architecture.md)\n- Original PR: feat: add read-only mode support for dashboard without API key","file_path":"/home/crystalin/projects/claude-nexus-proxy/docs/04-Architecture/ADRs/adr-019-dashboard-read-only-mode-security.md"}}]},{"role":"user","content":[{"type":"tool_result","content":"File created successfully at: /home/crystalin/projects/claude-nexus-proxy/docs/04-Architecture/ADRs/adr-019-dashboard-read-only-mode-security.md","tool_use_id":"toolu_01MuaQ7JmWcptGbBDZokeSmw"}]},{"role":"assistant","content":[{"text":"Now let me update the CLAUDE.md file to include security warnings:","type":"text"},{"id":"toolu_01USgMjd1yMUgWj4yqsjB6QN","name":"Edit","type":"tool_use","input":{"file_path":"/home/crystalin/projects/claude-nexus-proxy/CLAUDE.md","new_string":"**Dashboard Service** (`services/dashboard/`)\n\n- Monitoring UI\n- Analytics and usage charts\n- Request history browser\n- SSE for live updates\n- **⚠️ SECURITY WARNING**: Read-only mode (when `DASHBOARD_API_KEY` is not set) exposes all data without authentication.

Here's what was done:\n\n### 1. **Created ADR-019** (`docs/04-Architecture/ADRs/adr-019-dashboard-read-only-mode-security.md`)\n- Documents the decision to implement read-only mode\n- Clearly outlines the security implications\n- Provides considered alternatives\n- Recommends future deprecation with clear migration path\n- Includes implementation details for adding warnings\n\n### 2. **Updated CLAUDE.md**\n- Added security warning to Dashboard Service section\n- Added critical warning to the DASHBOARD_API_KEY environment variable description\n\n### 3. **Updated README.md**\n- Added detailed security warning comment in the environment variables example\n- Added prominent security warning in the Dashboard section\n\n### 4. **Enhanced Security Documentation** (`docs/03-Operations/security.md`)\n- Added critical security notice at the top of the document\n- Expanded the \"Exposed Dashboard\" vulnerability section with detailed warnings\n- Included specific examples of what data is exposed\n- Added instructions for checking vulnerability\n\n### 5. **Updated Deployment Guide** (`docs/03-Operations/deployment/docker.md`)\n- Added critical warning to dashboard Docker run command\n- Created comprehensive \"Security Considerations\" section\n- Included production security checklist with specific commands\n- Added network security recommendations\n\n### 6. **Updated Configuration Files**\n- Enhanced `.env.example` with critical security warnings\n- Added clear instructions about never leaving DASHBOARD_API_KEY unset\n\n### 7. **Updated Quick Start Guide** (`docs/00-Overview/quickstart.md`)\n- Added critical warning about setting DASHBOARD_API_KEY\n- Updated dashboard monitoring section with security warning\n\n### 8. **Updated ADR Index**\n- Added ADR-019 to the ADR README index\n- Fixed missing ADRs 016-018 in the index\n\n### Key Security Points Emphasized:\n\n1. **Read-only mode exposes ALL data** including:\n - Conversation histories\n - Token usage and costs\n - Account information\n - AI analysis results\n - Potentially sensitive customer data\n\n2. **Never deploy to production** without setting DASHBOARD_API_KEY\n\n3. **Recommended mitigations**:\n - Always set a strong DASHBOARD_API_KEY (32+ characters)\n - Restrict dashboard to internal networks only\n - Use reverse proxy with additional authentication\n - Block port 3001 at firewall level\n - Consider VPN access for dashboard\n\n4. **Future recommendations**:\n - Phase out read-only mode in future versions\n - Add deprecation warnings\n - Consider implementing a demo mode with synthetic data\n\nThe documentation now clearly communicates the security risks while maintaining backward compatibility and providing a clear migration path for existing users.","type":"text"}],"stop_reason":"end_turn","stop_sequence":null}
