| name | coding-agent-docs |
| description | Stay current with how OpenCode, OpenAI Codex, and Claude Code implement extensibility features (skills, slash commands, subagents, custom prompts). Use when comparing implementations across AI coding assistants, researching how a specific tool implements a feature, or syncing knowledge about agent extensibility patterns. Triggers include questions like "how does X implement skills?", "compare slash commands across tools", "what's the latest on Claude Code sub-agents?", or requests to understand agent extensibility approaches. |
AI Coding Agent Documentation Sync
Track and compare extensibility features across OpenCode, Codex, and Claude Code.
Quick Reference
See references/documentation-urls.md for all documentation URLs organized by tool and feature type.
Workflows
Fetch Current Documentation
- Read
references/documentation-urls.md to get relevant URLs
- Use WebFetch for each URL with a targeted prompt:
- For overview: "Summarize the main concepts and how this feature works"
- For comparison: "Extract the key configuration options, file structure, and capabilities"
- For implementation details: "List the required files, syntax, and examples"
Compare Implementations Across Tools
- Identify the concept to compare (skills, commands, agents)
- Fetch documentation from each tool using the feature mapping table
- Structure comparison around:
- Triggering: How is the feature invoked?
- Structure: What files/config are required?
- Capabilities: What can it do?
- Limitations: What constraints exist?
Research Specific Feature
- Identify which tool(s) to research
- Fetch the relevant documentation URL(s)
- Extract:
- Core concepts and terminology
- Required file structure
- Configuration options
- Example implementations
Concept Mapping
| Concept | OpenCode | Codex | Claude Code |
|---|
| Reusable workflows | Skills | Skills, Custom Prompts | Skills |
| User commands | Commands | - | Slash Commands |
| Autonomous tasks | Agents | - | Sub-agents |
Important Notes
- Documentation URLs may change; verify links still work before relying on them
- Each tool uses different terminology for similar concepts
- Features evolve rapidly; always fetch current docs rather than relying on cached knowledge
