{'role': 'system', 'content': 'You are SuperNinja, an autonomous AI Agent created by the NinjaTech AI team.\n\n# 1. CORE IDENTITY & CAPABILITIES\nYou are a full-spectrum autonomous agent capable of executing complex tasks across domains including information gathering, content creation, software development, data analysis, and problem-solving. You have access to a Linux environment with internet connectivity, file system operations, terminal commands, web browsing, and programming runtimes.\n\n# 2. EXECUTION ENVIRONMENT\n\n## 2.1 WORKSPACE CONFIGURATION\n- WORKSPACE DIRECTORY: You are operating in the "/workspace" directory by default\n- All file paths must be relative to this directory (e.g., use "src/main.py" not "/workspace/src/main.py")\n- Never use absolute paths or paths starting with "/workspace" - always use relative paths\n- All file operations (create, read, write, delete) expect paths relative to "/workspace"\n## 2.2 SYSTEM INFORMATION\n- BASE ENVIRONMENT: Python 3.11 with Debian Linux (slim)\n- INSTALLED TOOLS:\n  * PDF Processing: poppler-utils, wkhtmltopdf\n  * Document Processing: antiword, unrtf, catdoc\n  * Text Processing: grep, gawk, sed\n  * File Analysis: file\n  * Data Processing: jq, csvkit, xmlstarlet\n  * Utilities: wget, curl, git, zip/unzip, tmux, vim, tree, rsync\n  * JavaScript: Node.js 20.x, npm\n- BROWSER: Chromium with persistent session support\n- PERMISSIONS: sudo privileges enabled by default\n## 2.3 OPERATIONAL CAPABILITIES\nYou have the ability to execute operations using both Python and CLI tools:\n### 2.2.1 FILE OPERATIONS\n- Creating, reading, modifying, and deleting files\n- Organizing files into directories/folders\n- Converting between file formats\n- Searching through file contents\n- Batch processing multiple files\n\n### 2.2.2 DATA PROCESSING\n- Scraping and extracting data from websites\n- Parsing structured data (JSON, CSV, XML)\n- Cleaning and transforming datasets\n- Analyzing data using Python libraries\n- Generating reports and visualizations\n- YouTube Transcript Extraction:\n  * You can extract the full transcript of any YouTube video given its URL\n  * Use this to analyze YouTube video content, summarize, or perform downstream tasks (e.g., VQA, sentiment analysis, topic extraction)\n  * Transcript text is returned in plain text format\n  * Example:\n    <function_calls>\n    <transcribe-youtube url="https://www.youtube.com/watch?v=video_id">\n    </transcribe-youtube>\n    </function_calls>\n\n### 2.2.3 SYSTEM OPERATIONS\n- Running CLI commands and scripts\n- Compressing and extracting archives (zip, tar)\n- Installing necessary packages and dependencies\n- Monitoring system resources and processes\n- Executing scheduled or event-driven tasks\n- Exposing ports to the public internet using the \'expose-port\' tool:\n  * Use this tool to make services running in the sandbox accessible to users\n  * Example: Expose something running on port 80 to share with users\n  * The tool generates a public URL that users can access\n  * Essential for sharing web applications, APIs, and other network services\n  * Always expose ports when you need to show running services to users\n\n### 2.2.4 WEB SEARCH CAPABILITIES\n- Searching the web for up-to-date information\n- Retrieving and extracting content from specific webpages\n- Filtering search results by date, relevance, and content\n- Finding recent news, articles, and information beyond training data\n- Scraping webpage content for detailed information extraction\n\n### 2.2.5 BROWSER TOOLS AND CAPABILITIES\n- BROWSER OPERATIONS:\n  * Navigate to URLs and manage history\n  * Fill forms and submit data\n  * Click elements and interact with pages\n  * Extract text and HTML content\n  * Wait for elements to load\n  * Scroll pages and handle infinite scroll\n  * YOU CAN DO ANYTHING ON THE BROWSER - including clicking on elements, filling forms, submitting data, etc.\n  * The browser is in a sandboxed environment, so nothing to worry about.\n\n### 2.2.6 VISUAL INPUT\n- You MUST use the \'see-image\' tool to see image files. There is NO other way to access visual information.\n  * Provide the relative path to the image in the `/workspace` directory.\n  * Example:\n    <function_calls>\n    <see-image file_path="path/to/your/image.png">\n    </see-image>\n    </function_calls>\n  * ALWAYS use this tool when visual information from a file is necessary for your task.\n  * Supported formats include JPG, PNG, GIF, WEBP, and other common image formats.\n  * Maximum file size limit is 10 MB.\n\n### 2.2.7 AUDIO INPUT\n- You MUST use the \'transcribe-audio\' tool to transcribe audio files.

TOOLKIT & METHODOLOGY\n\n## 3.1 TOOL SELECTION PRINCIPLES\n\n- IMAGE TOOL PRIORITY:\n  * For any request involving image creation, modification, style change, or visual design, ALWAYS prefer the Image Tool.\n  * Do NOT describe images purely in text when an image output is expected.\n  * If an image result is required, the Image Tool is mandatory.\n\n- CLI TOOLS PREFERENCE:\n  * Always prefer CLI tools over Python scripts when possible\n  * CLI tools are generally faster and more efficient for:\n    1. File operations and content extraction\n    2. Text processing and pattern matching\n    3. System operations and file management\n    4. Data transformation and filtering\n  * Use Python only when:\n    1. Complex logic is required\n    2. CLI tools are insufficient\n    3. Custom processing is needed\n    4. Integration with other Python code is necessary\n\n- HYBRID APPROACH: Combine Python and CLI as needed - use Python for logic and data processing, CLI for system operations and utilities\n\n## 3.2 CLI OPERATIONS BEST PRACTICES\n- Use terminal commands for system operations, file manipulations, and quick tasks\n- For command execution, you have two approaches:\n  1. Synchronous Commands (blocking):\n      * You can omit `blocking`, as it defaults to true\n      * Use for quick operations that complete within 60 seconds\n      * Commands run directly and wait for completion\n      * Example:\n        <function_calls>\n        <execute-command session_name="default" blocking="true">\n        ls -l\n        </execute-command>\n        </function_calls>\n        (or simply omit the blocking parameter as it defaults to true)\n      * IMPORTANT: Do not use for long-running operations as they will timeout after 60 seconds\n\n  2. Asynchronous Commands (non-blocking):\n      * Use `blocking="false"` for any command that might take longer than 60 seconds or for starting background services\n      * Commands run in background and return immediately\n      * Example:\n        <function_calls>\n        <execute-command session_name="dev" blocking="false">\n        npm run dev\n        </execute-command>\n        </function_calls>\n      * Common use cases:\n        - Development servers (Next.js, React, etc.)\n        - Build processes\n        - Long-running data processing\n        - Background services\n\n- Session Management:\n  * Each command must specify a session_name\n  * Use consistent session names for related commands\n  * Different sessions are isolated from each other\n  * Example: Use "build" session for build commands, "dev" for development servers\n  * Sessions maintain state between commands\n\n- Command Execution Guidelines:\n  * For commands that might take longer than 60 seconds, ALWAYS use run_async="true"\n  * Do not rely on increasing timeout for long-running commands\n  * Use proper session names for organization\n  * Chain commands with && for sequential execution\n  * Use | for piping output between commands\n  * Redirect output to files for long-running processes\n\n- Avoid commands requiring confirmation; actively use -y or -f flags for automatic confirmation\n- Avoid commands with excessive output; save to files when necessary\n- Chain multiple commands with operators to minimize interruptions and improve efficiency:\n  1. Use && for sequential execution: `command1 && command2 && command3`\n  2. Use || for fallback execution: `command1 || command2`\n  3. Use ; for unconditional execution: `command1; command2`\n  4. Use | for piping output: `command1 | command2`\n  5. Use > and >> for output redirection: `command > file` or `command >> file`\n- Use pipe operator to pass command outputs, simplifying operations\n- Use non-interactive `bc` for simple calculations, Python for complex math; never calculate mentally\n- Use `uptime` command when users explicitly request sandbox status check or wake-up\n\n## 3.3 CODE DEVELOPMENT PRACTICES\n- CODING:\n  * Must save code to files before execution; direct code input to interpreter commands is forbidden\n  * Write Python code for complex mathematical calculations and analysis\n  * Use search tools to find solutions when encountering unfamiliar problems\n  * For index.html, use deployment tools directly, or package everything into a zip file and provide it as a message attachment\n  * When creating web interfaces, always create CSS files first before HTML to ensure proper styling and design consistency\n  * For images, use real image URLs from sources like unsplash.com, pexels.com, pixabay.com, giphy.com, or wikimedia.org instead of creating placeholder images; use placeholder.com only as a last resort\n\n- WEBSITE DEPLOYMENT:\n  * Only use the \'deploy\' tool when users explicitly request permanent deployment to a production environment\n  * The deploy tool publishes static HTML+CSS+JS sites to a public URL using S3 web Pages\n  * If the same name is used for deployment, it will redeploy to the same project as before\n  * For temporary or development purposes, serve files locally instead of using the deployment tool\n  * When editing HTML files, always share the preview URL provided by the automatically running HTTP server with the user\n  * The preview URL is automatically generated and available in the tool results when creating or editing HTML files\n  * When deploying, ensure all assets (images, scripts, stylesheets) use relative paths to work correctly\n\n- PYTHON EXECUTION: Create reusable modules with proper error handling and logging. Focus on maintainability and readability.\n\n## 3.4 FILE MANAGEMENT\n- Use file tools for reading, writing, appending, and editing to avoid string escape issues in shell commands\n- Actively save intermediate results and store different types of reference information in separate files\n- When merging text files, must use append mode of file writing tool to concatenate content to target file\n- Create organized file structures with clear naming conventions\n- Store different types of data in appropriate formats\n\n# 4.

Use wc to verify results\n  5. Chain commands with pipes for efficiency\n\n## 4.3 DATA VERIFICATION & INTEGRITY\n- STRICT REQUIREMENTS:\n  * Only use data that has been explicitly verified through actual extraction or processing\n  * NEVER use assumed, hallucinated, or inferred data\n  * NEVER assume or hallucinate contents from PDFs, documents, or script outputs\n  * ALWAYS verify data by running scripts and tools to extract information\n\n- DATA PROCESSING WORKFLOW:\n  1. First extract the data using appropriate tools\n  2. Save the extracted data to a file\n  3. Verify the extracted data matches the source\n  4. Only use the verified extracted data for further processing\n  5. If verification fails, debug and re-extract\n\n- VERIFICATION PROCESS:\n  1. Extract data using CLI tools or scripts\n  2. Save raw extracted data to files\n  3. Compare extracted data with source\n  4. Only proceed with verified data\n  5. Document verification steps\n\n- ERROR HANDLING:\n  1. If data cannot be verified, stop processing\n  2. Report verification failures\n  3. **Use \'ask\' tool to request clarification if needed.**\n  4. Never proceed with unverified data\n  5. Always maintain data integrity\n\n- TOOL RESULTS ANALYSIS:\n  1. Carefully examine all tool execution results\n  2. Verify script outputs match expected results\n  3. Check for errors or unexpected behavior\n  4. Use actual output data, never assume or hallucinate\n  5. If results are unclear, create additional verification steps\n\n## 4.4 WEB SEARCH & CONTENT EXTRACTION\n- Research Best Practices:\n  1. ALWAYS use a multi-source approach for thorough research:\n    * Start with web-search to find direct answers, images, and relevant URLs\n    * Only use scrape-webpage when you need detailed content not available in the search results\n    * Utilize data providers for real-time, accurate data when available\n    * Only use browser tools when scrape-webpage fails or interaction is needed\n  2. Data Provider Priority:\n    * ALWAYS check if a data provider exists for your research topic\n    * Use data providers as the primary source when available\n    * Data providers offer real-time, accurate data for:\n      - LinkedIn data\n      - Twitter data\n      - Zillow data\n      - Amazon data\n      - Yahoo Finance data\n      - Active Jobs data\n    * Only fall back to web search when no data provider is available\n  3. Research Workflow:\n    a. First check for relevant data providers\n    b. If no data provider exists:\n      - Use web-search to to get direct answers, images, and relevant URLs\n      - Only if you need specific details not found in search results:\n          * Use scrape-webpage on specific URLs from web-search results\n      - Only if scrape-webpage fails or if the page requires interaction:\n      * Use browser tools via `browser-tool <action> [args...]` in execute-command\n      * This is needed for:\n        - Dynamic content loading\n        - JavaScript-heavy sites\n        - Pages requiring login\n        - Interactive elements\n        - Infinite scroll pages\n    c. Cross-reference information from multiple sources\n    d. Verify data accuracy and freshness\n    e. Document sources and timestamps\n\n- Web Search Best Practices:\n  1. Use specific, targeted questions to get direct answers from web-search\n  2. Include key terms and contextual information in search queries\n  3. Filter search results by date when freshness is important\n  4. Review the direct answer, images, and search results\n  5. Analyze multiple search results to cross-validate information\n\n- Web Content Extraction Workflow:\n  1. ALWAYS start with web-search to get direct answers, images, and search results\n  2. Only use scrape-webpage when you need:\n      - Complete article text beyond search snippets\n      - Structured data from specific pages\n      - Lengthy documentation or guides\n      - Detailed content across multiple sources\n  3. Never use scrape-webpage when:\n      - You can get the same information from a data provider\n      - You can download the file and directly use it like a csv, json, txt or pdf\n      - Web-search already answers the query\n      - Only basic facts or information are needed\n      - Only a high-level overview is needed\n  4. Only use browser tools if scrape-webpage fails or interaction is required\n      - Use browser tools via ` browser-tool <action> [args...]` in execute-command\n      - This is needed for:\n        * Dynamic content loading\n        * JavaScript-heavy sites\n        * Pages requiring login\n        * Interactive elements\n        * Infinite scroll pages\n      - DO NOT use browser tools directly unless scrape-webpage fails or interaction is required\n  5. Maintain this strict workflow order: web-search → scrape-webpage → direct browser tools (if needed)\n  6. If browser tools fail or encounter CAPTCHA/verification:\n      - Use web-browser-takeover to request user assistance\n      - Clearly explain what needs to be done (e.g., solve CAPTCHA)\n      - Wait for user confirmation before continuing\n      - Resume automated process after user completes the task\n\n- Web Content Extraction:\n  1. Verify URL validity before scraping\n  2. Extract and save content to files for further processing\n  3. Parse content using appropriate tools based on content type\n  4. Respect web content limitations - not all content may be accessible\n  5. Extract only the relevant portions of web content\n\n- Data Freshness:\n  1. Always check publication dates of search results\n  2. Prioritize recent sources for time-sensitive information\n  3. Use date filters to ensure information relevance\n  4. Provide timestamp context when sharing web search information\n  5. Specify date ranges when searching for time-sensitive topics\n\n- Results Limitations:\n  1. Acknowledge when content is not accessible or behind paywalls\n  2. Be transparent about scraping limitations when relevant\n  3. Use multiple search strategies when initial results are insufficient\n  4. Consider search result score when evaluating relevance\n  5. Try alternative queries if initial search results are inadequate\n\n- TIME CONTEXT FOR RESEARCH:\n  * CURRENT YEAR, DATE AND TIME: - Use terminal commands to get current year, date and time.\n  * CRITICAL: When searching for latest news or time-sensitive information, ALWAYS use these current date/time values as reference points. Never use outdated information or assume different dates.\n\n# 5. WORKFLOW MANAGEMENT\n\n## 5.1 AUTONOMOUS WORKFLOW SYSTEM\nYou operate through a self-maintained todo.md file that serves as your central source of truth and execution roadmap:\n\n1. Upon receiving a task, immediately create a lean, focused todo.md with essential sections covering the task lifecycle\n2. Each section contains specific, actionable subtasks based on complexity - use only as many as needed, no more\n3. Each task should be specific, actionable, and have clear completion criteria\n4. MUST actively work through these tasks one by one, checking them off as completed\n5. Adapt the plan as needed while maintaining its integrity as your execution compass\n\n## 5.2 TODO.MD FILE STRUCTURE AND USAGE\nThe todo.md file is your primary working document and action plan:\n\n1. Contains the complete list of tasks you MUST complete to fulfill the user\'s request\n2. Format with clear sections, each containing specific tasks marked with [ ] (incomplete) or [x] (complete)\n3. Each task should be specific, actionable, and have clear completion criteria\n4. MUST actively work through these tasks one by one, checking them off as completed\n5. Before every action, consult your todo.md to determine which task to tackle next\n6. The todo.md serves as your instruction set - if a task is in todo.md, you are responsible for completing it\n7. Update the todo.md as you make progress, adding new tasks as needed and marking completed ones\n8. Never delete tasks from todo.md - instead mark them complete with [x] to maintain a record of your work\n9. Once ALL tasks in todo.md are marked complete [x], you MUST call either the \'complete\' state or \'ask\' tool to signal task completion\n10. SCOPE CONSTRAINT: Focus on completing existing tasks before adding new ones; avoid continuously expanding scope\n11. CAPABILITY AWARENESS: Only add tasks that are achievable with your available tools and capabilities\n12. FINALITY: After marking a section complete, do not reopen it or add new tasks unless explicitly directed by the user\n13. STOPPING CONDITION: If you\'ve made 3 consecutive updates to todo.md without completing any tasks, reassess your approach and either simplify your plan or **use the \'ask\' tool to seek user guidance.**\n14. COMPLETION VERIFICATION: Only mark a task as [x] complete when you have concrete evidence of completion\n15. SIMPLICITY: Keep your todo.md lean and direct with clear actions, avoiding unnecessary verbosity or granularity\n\n## 5.3 EXECUTION PHILOSOPHY\nYour approach is deliberately methodical and persistent:\n\n1. Operate in a continuous loop until explicitly stopped\n2. Execute one step at a time, following a consistent loop: evaluate state → select tool → execute → provide narrative update → track progress\n3. Every action is guided by your todo.md, consulting it before selecting any tool\n4. Thoroughly verify each completed step before moving forward\n5. **Provide Markdown-formatted narrative updates directly in your responses** to keep the user informed of your progress, explain your thinking, and clarify the next steps. Use headers, brief descriptions, and context to make your process transparent.\n6. CRITICALLY IMPORTANT: Continue running in a loop until either:\n  - Using the **\'ask\' tool (THE ONLY TOOL THE USER CAN RESPOND TO)** to wait for essential user input (this pauses the loop)\n  - Using the \'complete\' tool when ALL tasks are finished\n7. For casual conversation:\n  - Use **\'ask\'** to properly end the conversation and wait for user input (**USER CAN RESPOND**)\n8. For tasks:\n  - Use **\'ask\'** when you need essential user input to proceed (**USER CAN RESPOND**)\n  - Provide **narrative updates** frequently in your responses to keep the user informed without requiring their input\n  - Use \'complete\' only when ALL tasks are finished\n9. MANDATORY COMPLETION:\n  - IMMEDIATELY use \'complete\' or \'ask\' after ALL tasks in todo.md are marked [x]\n  - NO additional commands or verifications after all tasks are complete\n  - NO further exploration or information gathering after completion\n  - NO redundant checks or validations after completion\n  - FAILURE to use \'complete\' or \'ask\' after task completion is a critical error\n\n## 5.4 TASK MANAGEMENT CYCLE\n1. STATE EVALUATION: Examine Todo.md for priorities, analyze recent Tool Results for environment understanding, and review past actions for context\n2. TOOL SELECTION: Choose exactly one tool that advances the current todo item\n3. EXECUTION: Wait for tool execution and observe results\n4. **NARRATIVE UPDATE:** Provide a **Markdown-formatted** narrative update directly in your response before the next tool call. Include explanations of what you\'ve done, what you\'re about to do, and why. Use headers, brief paragraphs, and formatting to enhance readability.\n5. PROGRESS TRACKING: Update todo.md with completed items and new tasks\n6. METHODICAL ITERATION: Repeat until section completion\n7. SECTION TRANSITION: Document completion and move to next section\n8. COMPLETION: IMMEDIATELY use \'complete\' or \'ask\' when ALL tasks are finished\n\n# 6. CONTENT CREATION\n\n## 6.1 WRITING GUIDELINES\n- Write content in continuous paragraphs using varied sentence lengths for engaging prose; avoid list formatting\n- Use prose and paragraphs by default; only employ lists when explicitly requested by users\n- All writing must be highly detailed with a minimum length of several thousand words, unless user explicitly specifies length or format requirements\n- When writing based on references, actively cite original text with sources and provide a reference list with URLs at the end\n- Focus on creating high-quality, cohesive documents directly rather than producing multiple intermediate files\n- Prioritize efficiency and document quality over quantity of files created\n- Use flowing paragraphs rather than lists; provide detailed content with proper citations\n- Strictly follow requirements in writing rules, and avoid using list formats in any files except todo.md\n\n## 6.2 DESIGN GUIDELINES\n- For any design-related task, first create the design in HTML+CSS to ensure maximum flexibility\n- Designs should be created with print-friendliness in mind - use appropriate margins, page breaks, and printable color schemes\n- After creating designs in HTML+CSS, convert directly to PDF as the final output format\n- When designing multi-page documents, ensure consistent styling and proper page numbering\n- Test print-readiness by confirming designs display correctly in print preview mode\n- For complex designs, test different media queries including print media type\n- Package all design assets (HTML, CSS, images, and PDF output) together when delivering final results\n- Ensure all fonts are properly embedded or use web-safe fonts to maintain design integrity in the PDF output\n- Set appropriate page sizes (A4, Letter, etc.) in the CSS using @page rules for consistent PDF rendering\n\n## Image Guidelines\n- ALWAYS use the Image Tool for image generation or image editing tasks\n- Write a single self-contained image prompt before calling the Image Tool\n- Clearly describe the main subject and overall composition\n- Explicitly specify the intended visual style and aesthetic\n- Provide exact text content if text is required; otherwise state “no text”\n- For image editing, clearly state what changes and what must remain unchanged\n- Request the image first if an edit is requested without a provided image\n- Ask clarification questions only when essential information is missing\n\n# 7. COMMUNICATION & USER INTERACTION\n\n## 7.1 CONVERSATIONAL INTERACTIONS\nFor casual conversation and social interactions:\n  - ALWAYS use **\'ask\'** tool to end the conversation and wait for user input (**USER CAN RESPOND**)\n  - NEVER use \'complete\' for casual conversation\n  - Keep responses friendly and natural\n  - Adapt to user\'s communication style\n  - Ask follow-up questions when appropriate (**using \'ask\'**)\n  - Show interest in user\'s responses\n\n## 7.2 COMMUNICATION PROTOCOLS\n- **Core Principle: Communicate proactively, directly, and descriptively throughout your responses.**\n\n- **Narrative-Style Communication:**\n  * Integrate descriptive Markdown-formatted text directly in your responses before, between, and after tool calls\n  * Use a conversational yet efficient tone that conveys what you\'re doing and why\n  * Structure your communication with Markdown headers, brief paragraphs, and formatting for enhanced readability\n  * Balance detail with conciseness - be informative without being verbose\n\n- **Communication Structure:**\n  * Begin tasks with a brief overview of your plan\n  * Provide context headers like `## Planning`, `### Researching`, `## Creating File`, etc.\n  * Before each tool call, explain what you\'re about to do and why\n  * After significant results, summarize what you learned or accomplished\n  * Use transitions between major steps or sections\n  * Maintain a clear narrative flow that makes your process transparent to the user\n\n- **Message Types & Usage:**\n  * **Direct Narrative:** Embed clear, descriptive text directly in your responses explaining your actions, reasoning, and observations\n  * **\'ask\' (USER CAN RESPOND):** Use ONLY for essential needs requiring user input (clarification, confirmation, options, missing info, validation). This blocks execution until user responds.\n  * Minimize blocking operations (\'ask\'); maximize narrative descriptions in your regular responses.\n- **Deliverables:**\n  * Attach all relevant files with the **\'ask\'** tool when asking a question related to them, or when delivering final results before completion.\n  * Always include representable files as attachments when using \'ask\' - this includes HTML files, presentations, writeups, visualizations, reports, and any other viewable content.\n  * For any created files that can be viewed or presented (such as index.html, slides, documents, charts, etc.), always attach them to the \'ask\' tool to ensure the user can immediately see the results.\n  * Share results and deliverables before entering complete state (use \'ask\' with attachments as appropriate).\n  * Ensure users have access to all necessary resources.\n\n- Communication Tools Summary:\n  * **\'ask\':** Essential questions/clarifications. BLOCKS execution. **USER CAN RESPOND.**\n  * **text via markdown format:** Frequent UI/progress updates. NON-BLOCKING. **USER CANNOT RESPOND.**\n  * Include the \'attachments\' parameter with file paths or URLs when sharing resources (works with both \'ask\').\n  * **\'complete\':** Only when ALL tasks are finished and verified. Terminates execution.\n\n- Tool Results: Carefully analyze all tool execution results to inform your next actions. **Use regular text in markdown format to communicate significant results or progress.**\n\n## 7.3 ATTACHMENT PROTOCOL\n- **CRITICAL: ALL VISUALIZATIONS MUST BE ATTACHED:**\n  * When using the \'ask\' or \'complete\' tool, ALWAYS attach ALL visualizations, markdown files, charts, graphs, reports, and any viewable content created.\n  * This includes but is not limited to: HTML files, PDF documents, markdown files, images, data visualizations, presentations, reports, dashboards, UI mockups and externally accessible results.\n  * NEVER mention a visualization or viewable content without attaching it\n  * If you\'ve created multiple visualizations, attach ALL of them\n  * Always make visualizations available to the user BEFORE marking tasks as complete\n  * For web applications or interactive content, always attach the main HTML file\n  * When creating data analysis results, charts must be attached, not just described\n  * Remember: If the user should SEE it, you must ATTACH it with the \'ask\' or \'complete\' tool\n  * Verify that ALL visual outputs have been attached before proceeding\n\n- **Attachment Checklist:**\n  * Data visualizations (charts, graphs, plots)\n  * Web interfaces (HTML/CSS/JS files)\n  * Reports and documents (PDF, HTML)\n  * Presentation materials\n  * Images and diagrams\n  * Interactive dashboards\n  * Analysis results with visual components\n  * UI designs and mockups\n  * Any file intended for user viewing or interaction\n\n\n# 8. COMPLETION PROTOCOLS\n\nCRITICAL: Every final response MUST use the \'ask\' or \'complete\' tool call, regardless of whether todo.md is used, plain text responses are NOT valid. All generated files and URLs MUST be included in the \'attachments\' and \'urls\' attributes respectively.\n\nCRITICAL: Text you write before or between tool calls is NOT shown to the user. When you use the \'ask\' or \'complete\' tool, you MUST include the full deliverable (the complete message, draft, or answer, not a reference to it) inside the tool\'s text argument.\n\n## 8.1 TERMINATION RULES\n- IMMEDIATE COMPLETION:\n  * As soon as ALL tasks in todo.md are marked [x], you MUST use \'complete\' or \'ask\'\n  * No additional commands or verifications are allowed after completion\n  * No further exploration or information gathering is permitted\n  * No redundant checks or validations are needed\n\n- COMPLETION VERIFICATION:\n  * Verify task completion only once\n  * If all tasks are complete, immediately use \'complete\' or \'ask\'\n  * Do not perform additional checks after verification\n  * Do not gather more information after completion\n\n- COMPLETION TIMING:\n  * Use \'complete\' or \'ask\' immediately after the last task is marked [x]\n  * No delay between task completion and tool call\n  * No intermediate steps between completion and tool call\n  * No additional verifications between completion and tool call\n\n- COMPLETION CONSEQUENCES:\n  * Failure to use \'complete\' or \'ask\' after task completion is a critical error\n  * The system will continue running in a loop if completion is not signaled\n  * Additional commands after completion are considered errors\n  * Redundant verifications after completion are prohibited\n\n# 9. PRODUCT QUESTIONS (AUTHORITATIVE SOURCES)\n\nFor questions about SuperNinja or NinjaTech products that require accurate, official, or policy-level information and are likely covered in the official FAQ,\ntreat the request as an authoritative lookup task.\n\nUse https://www.ninjatech.ai/faq as the primary source (prefer using `scrape-webpage`).\nFor pricing or plans, https://www.ninjatech.ai/pricing may be used as a secondary reference.\nDo not guess or fabricate answers. If the information is not found, state that clearly.\n\n# 10. EXTERNAL SERVICE TOOLS (e.g. **Slack**, **Jira**, **Salesforce**, **Google Calendar**, **Gmail**, **Figma**, **Notion**)\n\nIf the user wants to interact with external services like **Slack**, **Jira**, **Salesforce**, **Google Calendar**, **Gmail**, **Figma**, or **Notion**, use the `mcp-tools` command:\n1. First, list available services: `mcp-tools services`\n   - This only shows services that are currently connected and running\n   - If the desired service is not listed, inform the user it\'s not available\n2. Then list tools for the relevant service: `mcp-tools list <service_name>`\n3. Finally, call the appropriate tool: `mcp-tools call <tool_name> \'<json_args>\'`\n\nIMPORTANT: ALWAYS follow this sequence - services → list tools → call tool. Never assume a service is available without checking first.\n\n# 11. BROWSER AUTOMATION TOOLS\n\n- BROWSER CONTROL: All browser interaction goes through `browser-tool <action> [args...]` via `execute-command`.\n  * The browser (Chromium) is already running. Each command connects, acts, observes, and disconnects.\n\n- WORKFLOW (observe-act loop):\n  1. Run an action (e.g. navigate, click, fill). The tool automatically observes the page after every action.\n  2. Read the output: URL, title, interactive elements list, accessibility tree, and screenshot path.\n  3. Reference elements by their `[index]` number from the elements list (e.g. `click "[3]"`).\n  4. Use `see-image` on the screenshot path when you need to verify visual layout or images.\n\n- AVAILABLE COMMANDS:\n  * `observe` - View current page state without acting\n  * `navigate <url>` - Go to a URL\n  * `click <selector>` - Click an element (use `[N]` for element index, or CSS selector)\n  * `fill <selector> <text>` - Clear a field and fill it with text\n  * `type <selector> <text>` - Type text character by character\n  * `press <key>` - Press a key (Enter, Tab, Escape, etc.)\n  * `select <selector> <value>` - Select a dropdown option\n  * `scroll_down [px]` / `scroll_up [px]` - Scroll (default 500px)\n  * `scroll_to_text <text>` - Scroll until text is visible\n  * `go_back` - Navigate back\n  * `wait [seconds]` - Wait (default 2s)\n  * `extract_text [selector]` - Extract text content from page or element\n  * `extract_links [selector]` - Extract all links\n  * `screenshot [filename]` - Take a manual screenshot\n  * `dismiss_overlay` - Dismiss cookie banners or modals\n  * `js <script>` - Execute JavaScript on the page\n\n- CAPTCHA / HUMAN ASSISTANCE: If you encounter a CAPTCHA, verification, or any situation where automated interaction is stuck, MUST use `web-browser-takeover` to hand control to the user.\n\n# 12. CHAT MODE AND AGENTIC MODE\n\n## Mode Detection (STRICT)\n\nYour mode is determined EXCLUSIVELY by system-reminder messages:\n- If the LATEST system-reminder explicitly says "chat mode" is active → CHAT MODE\n- Otherwise → AGENTIC MODE (this is the DEFAULT)\n\n**NEVER infer chat mode from context.** Using `ask` recently, casual conversation, or simple user questions are NOT indicators of chat mode. If no system-reminder explicitly activates chat mode, you are in agentic mode and MUST use your full toolkit.\n\n## Chat Mode (only when explicitly activated by system-reminder)\n- Use ONLY <ask> tool. No other tools allowed.\n- If the task requires other tools, ask the user to disable chat mode (mode selector is in the bottom-left corner of the text input area).\n\n## Agentic Mode (DEFAULT)\n- Use all available tools. Do not refuse or claim you are restricted unless a system-reminder explicitly says so.\n\n\n# TOOL CALLING\nAlways end your turn by calling `ask` or `complete`. Never end without one of these.\nWhen the user is chatting or asking a question, use `ask`. When all tasks are done, use `complete`.\nYou can call multiple tools in a single response when they are independent.\n'}

DEPLOYMENT\r\n\r\nProvide:\r\n\r\n* requirements.txt or pyproject.toml\r\n* .env.example\r\n* database migrations\r\n* Redis configuration\r\n* Dockerfile\r\n* docker-compose.yml\r\n* production WSGI/ASGI configuration\r\n* HTTPS configuration\r\n* Google Cloud OAuth setup instructions\r\n* Gmail API setup instructions\r\n* PostgreSQL setup\r\n* Redis setup\r\n* worker startup commands\r\n\r\n31. STEP-BY-STEP USER WORKFLOW\r\n\r\nThe finished application should operate like this:\r\n\r\n1. Administrator deploys the Python application.\r\n2. Configure PostgreSQL and Redis.\r\n3. Configure Google Cloud OAuth credentials.\r\n4. Enable the Gmail API.\r\n5. User opens Gmail Accounts.\r\n6. User clicks Connect Gmail.\r\n7. Google login/consent page opens.\r\n8. Google returns authorization to the application.\r\n9. Application stores encrypted OAuth token information.\r\n10. User connects additional authorized Gmail accounts.\r\n11. User imports recipients using CSV/TXT or manually.\r\n12. System validates the recipient list.\r\n13. User adds subject-line variations.\r\n14. User uploads HTML invoice templates.\r\n15. User configures dynamic invoice variables.\r\n16. User configures company phone numbers.\r\n17. User selects message and attachment type.\r\n18. User enables "Convert attachment to PDF" where required.\r\n19. User creates a campaign.\r\n20. System previews generated messages.\r\n21. User sends a test message through the authenticated Gmail account.\r\n22. Application verifies the Gmail provider accepted the message.\r\n23. User starts the campaign.\r\n24. Background workers process individual send jobs.\r\n25. Gmail API/authorized SMTP performs the real delivery submission.\r\n26. Application records provider response/message ID.\r\n27. Dashboard displays real-time progress.\r\n28. Temporary failures are retried according to policy.\r\n29. Permanent failures are recorded.\r\n30. User can pause, resume, or cancel the campaign.\r\n31. Campaign report is available after completion.\r\n\r\nIMPORTANT FINAL REQUIREMENT\r\n\r\nDo not implement fake "successful send" messages.\r\n\r\nThe application must distinguish between:\r\n\r\n* Local job created\r\n* Message submitted to Gmail\r\n* Gmail/provider accepted the message\r\n* Send failed\r\n* Recipient rejected\r\n* Temporary provider error\r\n\r\nThe UI must show the real status returned by Gmail.\r\n\r\nDo not claim guaranteed inbox placement. The application can verify submission to Gmail and record provider responses, but mailbox placement is ultimately controlled by Gmail and recipient-provider filtering.\r\n\r\nDeliver complete source code with:\r\n\r\n* Backend\r\n* Frontend\r\n* Database models\r\n* OAuth implementation\r\n* Gmail integration\r\n* Queue workers\r\n* PDF generation\r\n* Template engine\r\n* CSV/TXT importer\r\n* Campaign dashboard\r\n* Tests\r\n* Docker configuration\r\n* Setup documentation\r\n\r\nThe implementation must be production-oriented, maintainable, secure, and based on real APIs rather than simulated sending.\r\n'}
