Context Loader Skill for Gemini

Purpose

Load shared project context from .claude/ directory to ensure Gemini CLI operates with the same knowledge as Claude Code and Codex CLI.

When to Activate

ALWAYS - This skill should run at the beginning of research or analysis tasks.

Workflow

Step 1: Load Coding Rules

Read relevant files from .claude/rules/:

.claude/rules/
├── coding-principles.md   # Simplicity, single responsibility, early return
├── dev-environment.md     # uv, ruff, ty, pytest requirements
├── language.md            # Think in English, respond in Japanese
├── security.md            # Secrets, validation, SQLi/XSS prevention
└── testing.md             # TDD, AAA pattern, 80% coverage

Step 2: Load Design Documentation

Read .claude/docs/DESIGN.md for:

• Architecture decisions
• Implementation patterns
• Library choices and constraints

Step 3: Check Library Documentation

If the task involves specific libraries, read relevant files from:

.claude/docs/libraries/

Step 4: Execute Research Task

With the loaded context, execute the requested research/analysis following:

• Project coding principles
• Existing design decisions
• Library constraints

Key Rules to Remember

1. Simplicity first - Recommend readable solutions over complex
2. Type hints required - Suggest typed code
3. Use uv - Reference uv for package management
4. Security - Highlight security considerations

Language Protocol

• Thinking/Reasoning: English
• Code examples: English (variables, functions, comments)
• Output: Structured markdown, suitable for documentation

Output Guidelines

When providing research results:

• Structure with clear headings
• Include code examples when relevant
• Cite sources from web search
• Note constraints relevant to this project
• Save comprehensive findings to .claude/docs/research/
