What makes agentic coding applications different? TBH, it's mostly their system prompts, the tools they provide, and how they actually use them. In this repo, I'm documenting these system prompts and tools from different agentic coding solutions.

## Agent Comparison
| Agent | Provider | Type | Tools |
|-------|----------|------|-------|
| [Claude Code](./agents/claude-code/) | Anthropic | CLI | 15 |
| [Gemini CLI](./agents/gemini-cli/) | Google | CLI | 11 |
| [Cline](./agents/cline/) | Open Source | VS Code | 12 |
| [Aider](./agents/aider/) | Open Source | CLI | Git-based |
| [Roo Code](./agents/roo-code/) | RooCode Inc | VS Code | 12 |

| [Codex CLI (Rust)](./agents/codex-rs/) | OpenAI | CLI | 1 |
## What's Included
Each agent directory contains:
- **System Prompts** - Complete prompt templates with role definitions and instructions
- **Tool Documentation** - Detailed API specifications for all available tools
- **Source Attribution** - Direct links to original sources with retrieval dates
- **README** - Overview with GitHub repository links and feature summaries
## Research Value
This collection provides insights into:
- **Prompt Engineering Patterns** - How production systems structure AI instructions
- **Tool Design** - Common patterns in AI agent tooling and capabilities
- **Safety Measures** - Security considerations and defensive programming practices
- **User Experience** - How different agents handle interaction and workflow management
## Contributing
1. Create a new directory under `agents/[agent-name]/`
2. Add a `system-prompt.md` file with the complete system prompt
3. Document tools in `agents/[agent-name]/tools/` directory
4. Include source information and retrieval date in headers
5. Follow the established template formats (see [CLAUDE.md](./CLAUDE.md))
## Roadmap
Planned additions to this repository:
- [ ] **Tools Comparison** - Detailed analysis and comparison of tools across different agents
- [ ] **Prompts Analysis** - In-depth analysis of prompt engineering patterns and techniques
