Claude Code Subagents support!

[CasJam]

This release adds support for Claude Code's new subagents feature!

Added

• Claude Code Specialized Subagents - New agents to offload specific tasks for improved efficiency:
  • test-runner.md - Handles test execution and failure analysis with minimal toolset
  • context-fetcher.md - Retrieves information from files while checking context to avoid duplication
  • git-workflow.md - Manages git operations, branches, commits, and PR creation
  • file-creator.md - Creates files, directories, and applies consistent templates
• Agent Detection Pattern - Single check at process start with boolean flags for efficiency
• Subagent Integration across all instruction files with automatic fallback for non-Claude Code users

Changed

• Instruction Files - All updated to support conditional agent usage:
  • execute-tasks.md - Uses git-workflow (branch management, PR creation), test-runner (full suite), and context-fetcher (loading lite files)
  • execute-task.md - Uses context-fetcher (best practices, code style) and test-runner (task-specific tests)
  • plan-product.md - Uses file-creator (directory creation) and context-fetcher (tech stack defaults)
  • create-spec.md - Uses file-creator (spec folder) and context-fetcher (mission/roadmap checks)
• Standards Files - Updated for conditional agent usage:
  • code-style.md - Uses context-fetcher for loading language-specific style guides
• Setup Scripts - Enhanced to install Claude Code agents:
  • setup-claude-code.sh - Downloads all agents to ~/.claude/agents/ directory

Improved

• Context Efficiency - Specialized agents use minimal context for their specific tasks
• Code Organization - Complex operations delegated to focused agents with clear responsibilities
• Error Handling - Agents provide targeted error analysis and recovery strategies
• Maintainability - Cleaner main agent code with operations abstracted to subagents
• Performance - Reduced context checks through one-time agent detection pattern

Technical Details

• Each agent uses only necessary tools (e.g., test-runner uses only Bash, Read, Grep, Glob)
• Automatic fallback ensures compatibility for users without Claude Code
• Consistent IF has_[agent_name]: pattern reduces code complexity
• All agents follow Agent OS conventions (branch naming, commit messages, file templates)
