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

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
