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

1. Read references/documentation-urls.md to get relevant URLs
2. 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

1. Identify the concept to compare (skills, commands, agents)
2. Fetch documentation from each tool using the feature mapping table
3. 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

1. Identify which tool(s) to research
2. Fetch the relevant documentation URL(s)
3. 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
