• ログアウト時に /api/auth/logout を呼び出す処理を追加
• Vite の proxy に /keycloak（および auth API 経路）を追加し開発時のクロスオリジン問題に対応
• Keycloak 認証フローの focused テスト（fastapi_app/test/test_01_keycloak_auth.py）を追加
• 追加/変更箇所に対する targeted 検証（pytest, eslint）を実施

Original prompt

Start implementation

[Chronological Review: The conversation began with the user requesting to implement authentication and authorization features using KeyCloak. The user provided details about the current application setup, including a FastAPI backend and a React frontend, and specified the desired changes to the authentication structure. The user then outlined a plan for the implementation, including the use of cookies and sessions, and requested updates to the plan based on additional requirements regarding cross-origin issues and callback URLs. The user expressed readiness to start the implementation, indicating no further questions.]

[Intent Mapping:

1. "認証及び認可機能をKeyCloakを使用した実装に変更したい。" - User wants to change the authentication mechanism to use KeyCloak.
2. "Cookieのクロスオリジン問題については、vite.config.tsのproxyを使用する形とする。" - User wants to address cross-origin issues using a proxy in vite.config.ts.
3. "KeyCloakのコールバックURL: 必要であれば、vite.config.tsのproxyを使用して..." - User is considering using the proxy for KeyCloak callback URLs.
4. "ここまでの計画作業を開始したい。" - User is ready to start the implementation work.]

[Technical Inventory:

• Technologies: FastAPI, React, KeyCloak, Redis (for session storage), Vite (for frontend development).
• Architectural Decisions: Multi-tenant authentication using KeyCloak, OpenID Connect compliance, cookie and session-based authentication.]

[Code Archaeology:

• File: app.py
  • Function: login(request: dict) - This function is currently a placeholder for authentication logic.
• File: vite.config.ts - To be modified for proxy settings to handle cross-origin requests.]

[Progress Assessment:

• Completed Tasks: User has outlined the current application structure and the desired changes.
• Partially Complete Work: Implementation plan is ready, but actual coding has not yet begun.]

[Context Validation: All necessary context for continuing the implementation is captured, including user goals and technical requirements.]

[Recent Commands Analysis:

• Last Agent Commands: User requested to start the implementation.
• Tool Results Summary: No specific tool results were generated as the user was preparing to begin implementation.
• Pre-Summary State: The agent was actively discussing the implementation plan and preparing to start coding.
• Operation Context: The user is focused on implementing the authentication changes using KeyCloak and addressing related technical requirements.]

1. Conversation Overview: - Primary Objectives: User wants to implement authentication and authorization using KeyCloak, with specific requirements for cookie handling and cross-origin issues. - Session Context: The conversation has progressed from outlining the current application setup to detailing the desired changes and readiness to start implementation. - User Intent Evolution: The user has clarified their goals and requirements, leading to a structured plan for implementation.

2. Technical Foundation:

• FastAPI: Backend framework for the application.
• React: Frontend framework with a login screen.
• KeyCloak: Authentication server to be integrated for user management.
• Redis: Potential storage for session IDs.
• Vite: Development server for the React application, with proxy settings to handle cross-origin requests.

3. Codebase Status:

• File Name: app.py
  • Purpose: Contains the FastAPI application logic, including the login endpoint.
  • Current State: Placeholder function for login authentication.
  • Key Code Segments: @app.post("/api/login", include_in_schema=False) - Defines the login endpoint.
• File Name: vite.config.ts
  • Purpose: Configuration for the Vite development server.
  • Current State: To be updated for proxy settings.

4. Problem Resolution:

• Issues Encountered: Cross-origin issues with cookie handling.
• Solutions Implemented: Plan to use Vite's proxy for handling these issues.
• Debugging Context: No specific debugging has been initiated yet.
• Lessons Learned: Clear requirements and structured planning are essential for successful implementation.

5. Progress Tracking:

• Completed Tasks: User has defined the current application structure and desired changes.
• Partially Complete Work: Implementation plan is ready; coding has not yet started.
• Validated Outcomes: None yet, as implementation has not begun.

6. Active Work State:

• Current Focus: User is ready to start the implementation of the authentication changes.
• Recent Context: User has confirmed their readiness to begin coding based on the outlined plan.
• Working Code: No specific code has been modified yet; the focus is on planning.
• Immediate Context: User is prepared to start the implementation of KeyCloak integration.

7. Recent Operations:

• Last Agent Commands: User requested to start implementation.
• Tool Results Summary: No specific results were generated; the user is preparing to begin coding.
• Pre-Summary State: The agent was discussing the implementation plan and preparing to...
