# Agent Instructions

This document outlines the operational guidelines and standards for agents working in this workspace.

## 1. Language Standards

- Code & Comments: All comments, documentation strings (docstrings), and variable names in source code files (everything outside the `docs/` directory) must be written in English.
- Documentation: Files within the `docs/` directory may be written in the user's preferred language (e.g., Japanese).

## 2. Package Management

- Tool: Use uv as the Python package manager for this project.

## 3. Task Documentation Workflow

When receiving a request that is neither a simple question nor a single-step task, follow this workflow:

### Create Task Document

- Create a new markdown file in the `docs/tasks/` directory.
- Naming convention: `YYYYMMDD_{sequence}.md` (e.g., `20251123_01.md`, `20251123_02.md`).
- This file is referred to as the "Task Document".

### Content Requirements

- Language: Write the content in the language the user is currently using.
- Breakdown: Decompose the requested task into specific, actionable steps.

### User Confirmation

- CRITICAL: After creating the Task Document and BEFORE starting any implementation work, you must present the plan to the user and ask for confirmation that the approach is correct.

### Maintenance

- Continuously update and edit the Task Document to reflect progress, changes in requirements, or additional information discovered during execution.
