It designs personalized, multi-turn study pathways tailored to individual student needs by dynamically diagnosing knowledge gaps, checking inputs for security violations, retrieving reference material via an MCP retrieval-augmented generation (RAG) vector store, and yielding structured 7-day study plans. Incorporating two distinct Human-in-the-Loop (HITL) checkpointsβ€”one for security moderation and another for parent/teacher study plan approvalβ€”the system ensures that educational material is safe, relevant, and fully aligned with pedagogical requirements. ## πŸŽ₯ Video Demonstration [](https://youtu.be/YrWtIcUnS5M) ## πŸ—οΈ Architecture and Agent Hierarchy The agent workflow is structured as a directed graph of nodes orchestrating different sub-agents and validation rules. Below is the ASCII architecture diagram showing the execution path: ``` +----------------------------------------+ | Student Input | +----------------------------------------+ | v +-------------------------+ | parse_input | +-------------------------+ | v +-------------------------+ | security_checkpoint | | security_moderation | (HITL Checkpoint 1) +------------------+ [safe] +-----------------------+ | v (grades quiz / subtopics) +------------------+ | weakness_tracker | +------------------+ | v (finds subtopic weaknesses) +----------------------+ | study_plan_generator | loop back to study_plan_generator ``` --- ## πŸ“‹ Prerequisites Before setting up the project, ensure you have the following installed: * **Python 3.13+**: The core execution runtime. * **Node.js 18+**: Required to run the frontend SPA student interface. * **uv**: Modern, high-performance Python package manager (highly recommended). * **Google Cloud SDK (gcloud)**: Required for Cloud services (if deploying to GCP). * **Groq API Key**: A valid API Key from Groq Console. --- ## πŸš€ Quick-Start Follow these steps to clone, configure, and boot up the local playground and teacher dashboard: ### 1. Clone the Repository ```bash git clone capstone-study-coach cd capstone-study-coach/trifecta-agent ``` ### 2. Install Dependencies Set up the virtual environment and install both Python back-end packages and Node.js front-end packages: ```bash # Install Python packages and CLI utilities pip install -e ".[dev]" # Download required fonts for PDF export generation python scripts/download_fonts.py # Install frontend UI dependencies cd frontend && npm install cd .. ``` ### 3. Configure the Environment Create a `.env` file in the `trifecta-agent` root folder based on the example: ```bash copy .env.example .env ``` Open `.env` and configure your API key and port preferences: ```env GROQ_API_KEY=gsk_YourActualAPIKeyHere ADK_BASE_URL=http://127.0.0.1:8001 ALLOW_ORIGINS=* ``` ### 4. Launch the System Run the predefined commands in separate terminals (or use the provided `start.ps1` script on Windows): * **Backend Agent Server (ADK)**: ```bash # Launches the integrated ADK server & MCP endpoints at http://127.0.0.1:8001 uvicorn trifecta_agent.fast_api_app:app --port 8001 ``` * **Teacher/Moderator Dashboard (FastAPI)**: ```bash # Launches Uvicorn API server & glassmorphic SPA at http://127.0.0.1:8080 make dashboard ``` * **Student UI (Vite + React)**: ```bash # Launches Vite development server at http://localhost:7860 make student-ui ``` --- ## πŸ€– Sub-Agents & HITL Flows The Personal Trifecta employs modular sub-agents to divide responsibilities, combined with interactive checkpoints for safety and quality control: ### Sub-Agents 1. **Security Checkpoint (PII Redaction & Injection Defense)**: Uses Microsoft Presidio Analyzer and Anonymizer engines to scrub names, phone numbers, SSNs, email addresses, and student IDs. It also inspects inputs for prompt injection attack patterns. 2. **Interactive Quiz Agent**: Triggers a turn-by-turn multiple-choice testing flow. It queries the document index via FastMCP to ground the generated questions and requests Groq (Llama 3) to construct exactly 5 questions based on the student's selected difficulty. 3. **Weakness Tracker Agent**: A deterministic, rule-based Python analyzer. It aggregates historical quiz responses, groups them by subtopic, flags any subtopic scoring below `WEAKNESS_THRESHOLD` (default: `60%`), and assigns priority categories (`high`, `medium`, `low`). 4. **Study Plan Generator Agent**: Prompts the Groq (Llama 3) model to synthesize a structured 7-day schedule utilizing structured JSON formatting. It prioritizes identified high-priority weakness topics, integrates FastMCP study resources, and narrates a motivational introduction. ### Human-in-the-Loop (HITL) Checkpoints 1. **Security Escalation (Checkpoint 1)**: If `security_checkpoint` detects a potential prompt injection keyword, the workflow pauses, raising a `security_escalation` interrupt. A human moderator must audit the input on the Teacher Dashboard to mark it **Safe** (anonymizing and resuming the quiz) or **Malicious** (raising a value error and terminating the session). 2. **Study Plan Approval (Checkpoint 2)**: Before a 7-day study plan is delivered to the student, the workflow pauses, creating a `study_plan_approval` interrupt. A teacher or parent reviews the plan on the dashboard and can choose to: - **Approve**: Delivers the study plan directly to the student UI. - **Revise**: Submits a revision note (e.g., "Add more algorithms practice") which routes execution back to the `study_plan_generator` to rebuild the plan. - **Reject**: Cancels the study plan and notifies the student. --- ## πŸ“„ Ingesting Materials & Teacher Console Navigation To ground the quiz questions and study plans, and manage the student experience, perform the following steps: ### πŸ“Š Teacher Console Features The Teacher Administration Console at `http://127.0.0.1:8080` provides five major tabs: 1. **Overview & Charts**: Real-time KPI summaries (Active Sessions, Awaiting Reviews, Avg Accuracy, and Indexed Chunks) and Chart.js graphs mapping subtopic proficiency and timeline activity. 2. **Student Sessions**: Registry of active sessions. Teachers can click on any Session ID to inspect a deep-dive Student Profile, displaying PII audit logs, question-by-question quiz answers, and generated plan schedules. 3. **Review Queue**: Consolidated center to resolve HITL prompts, displaying a visual day-by-day preview grid for proposed study plans. 4. **MCP Knowledge Base**: Drag-and-drop document upload paired with an index browser to search and preview RAG chunks. 5. **Agent Settings**: Adjust thresholds (e.g. weakness threshold, quiz length, model) dynamically. ### 1. Ingest Study Materials 1. Open the **Teacher Console** at `http://127.0.0.1:8080` and switch to the **MCP Knowledge Base** tab. 2. Drag & drop or browse to select a PDF, TXT, or Markdown document in the upload zone. 3. Click **Upload to MCP Vector Store**. The file is forwarded to the FastMCP server, split into overlapping chunks, and indexed into the local `index.json` vector file. You can search indexed chunks in the real-time inspector. ### 2. Play a Quiz Session 1. Open the **Student UI** at `http://localhost:7860` (or run a CLI session in the playground). 2. Start a session by entering a topic and difficulty (e.g., "Python loops hard"). 3. The quiz agent will search the MCP index for loops, build 5 questions, and present them one-by-one. 4. Answer each question. The agent provides immediate feedback. 5. After the final question, the **Weakness Tracker** prints a report, and the **Study Plan Generator** drafts a plan. 6. The UI will pause and display "Waiting for parent/teacher approval...". 7. Go to the dashboard, click **Review**, insert optional instructions, and click **Approve Plan** or **Request Revision**. 8. The student UI immediately updates with the approved plan. 9. **Export**: Students can click the Download PDF button to receive a beautifully branded, offline-ready ReportLab A4 PDF of their study schedule. --- ## πŸ“Š Running Evaluations The evaluation loop measures response quality and graph performance against custom datasets. ### Configuration Metrics are defined in `tests/eval/eval_config.yaml`. The suite utilizes a custom LLM-as-a-Judge metric (`custom_response_quality`) to score agent responses on a scale from 1 (poor) to 5 (excellent), along with a programmatic metric (`agent_turn_count`) to track conversation lengths. ### Run Evaluations Use the `agents-cli` executable to generate conversation traces and run evaluation metrics: ```bash # Step 1: Synthesize testing datasets (optional) agents-cli eval dataset synthesize --count 10 # Step 2: Generate traces using test inputs agents-cli eval generate --dataset tests/eval/datasets/basic-dataset.json --output eval_traces/ # Step 3: Grade the traces using configured metrics agents-cli eval grade --config tests/eval/eval_config.yaml --traces eval_traces/ --output grade_results.json ``` To run regression comparison or cluster failures: ```bash # Compare candidate traces against baseline agents-cli eval compare baseline_grades.json grade_results.json # Cluster and analyze failure modes agents-cli eval analyze grade_results.json ``` --- ## πŸ† Kaggle Submission Notes: Agents for Good (Education Track) When packaging this agent for submission to the **Kaggle Agents for Good β€” Education Track**, review the following structural configurations: 1. **API Key Loading**: The agent is designed to run self-contained. It reads `GROQ_API_KEY` from the environment. Ensure this key is injected during notebook execution or kaggle secret setup. 2. **Offline Execution & Local Ingestion**: * The MCP document vector store uses a lightweight, self-contained mathematical TF-IDF engine inside `mcp_server/server.py`. * It relies on a local JSON file (`index.json`) for persistence, eliminating external database dependencies. * If submitting to an offline environment, ensure `index.json` is packaged inside the zip bundle so pre-ingested syllabus materials are readable. 3. **Container Constraints**: The FastAPI server and MCP server run internally as stdio processes. For submission notebook execution: * Package the dependencies in a single `requirements.txt` or configure the notebook to run `pip install -e .` offline using wheelhouses. * Do not run uvicorn as a blocking process; execute the agent directly using the `Runner` script or the `agents-cli` harness. --- ## πŸ“„ License This project is licensed under the Apache License, Version 2.0.
