- Add explicit task() invocation syntax to codebase-agent with examples
- Include when-to-use guidance for each subagent (4+ files, simple tasks, etc.)
- Add comprehensive OpenCode context reference cheatsheet covering:
- File references with @ symbol (immediate vs lazy loading)
- Agent invocation patterns (task tool vs @ syntax)
- Shell command execution with backtick syntax
- Best practices and anti-patterns
- Complete real-world examples and templates
This improves AI agent reliability in delegating to subagents by providing
clear, explicit invocation patterns following research-backed progressive
disclosure principles.
