When & Why to Use This Skill

Codeagent is a versatile multi-backend AI orchestration tool designed to streamline complex software engineering tasks. By integrating powerful models like Codex, Claude, and Gemini, it enables developers to execute automated code generation, deep repository analysis, and large-scale refactoring. The skill supports advanced features such as parallel task execution, file-based context referencing using @syntax, and session management, making it an essential utility for high-efficiency AI-assisted development.

Use Cases

  • Multi-Backend Code Refactoring: Leverage Codex for deep logic analysis and dependency tracking to perform precise, large-scale refactoring across complex codebases.
  • Automated Technical Documentation: Use the Claude backend to automatically generate comprehensive README files, API specifications, and professional documentation directly from source code.
  • Rapid UI/UX Prototyping: Utilize the Gemini backend to scaffold responsive UI components and design system layouts with high visual and functional consistency.
  • Parallel Task Orchestration: Execute multiple dependent coding tasks simultaneously by assigning specific AI backends to their strengths, optimizing both performance and cost.
  • Automated Code Review and Analysis: Perform automated call graph analysis and module dependency checks to identify architectural improvements and performance bottlenecks.

Codeagent Wrapper Integration

Overview

Execute codeagent-wrapper commands with pluggable AI backends (Codex, Claude, Gemini). Supports file references via @ syntax, parallel task execution with backend selection, and configurable security controls.

When to Use

  • Complex code analysis requiring deep understanding
  • Large-scale refactoring across multiple files
  • Automated code generation with backend selection

Usage

HEREDOC syntax (recommended):

codeagent-wrapper --backend codex - [working_dir] <<'EOF'
<task content here>
EOF

With backend selection:

codeagent-wrapper --backend claude - . <<'EOF'
<task content here>
EOF

Simple tasks:

codeagent-wrapper --backend codex "simple task" [working_dir]
codeagent-wrapper --backend gemini "simple task" [working_dir]

Backends

Backend Command Description Best For
codex --backend codex OpenAI Codex (default) Code analysis, complex development
claude --backend claude Anthropic Claude Simple tasks, documentation, prompts
gemini --backend gemini Google Gemini UI/UX prototyping

Backend Selection Guide

Codex (default):

  • Deep code understanding and complex logic implementation
  • Large-scale refactoring with precise dependency tracking
  • Algorithm optimization and performance tuning
  • Example: "Analyze the call graph of @src/core and refactor the module dependency structure"

Claude:

  • Quick feature implementation with clear requirements
  • Technical documentation, API specs, README generation
  • Professional prompt engineering (e.g., product requirements, design specs)
  • Example: "Generate a comprehensive README for @package.json with installation, usage, and API docs"

Gemini:

  • UI component scaffolding and layout prototyping
  • Design system implementation with style consistency
  • Interactive element generation with accessibility support
  • Example: "Create a responsive dashboard layout with sidebar navigation and data visualization cards"

Backend Switching:

  • Start with Codex for analysis, switch to Claude for documentation, then Gemini for UI implementation
  • Use per-task backend selection in parallel mode to optimize for each task's strengths

Parameters

  • task (required): Task description, supports @file references
  • working_dir (optional): Working directory (default: current)
  • --backend (required): Select AI backend (codex/claude/gemini)
    • Note: Claude backend only adds --dangerously-skip-permissions when explicitly enabled

Return Format

Agent response text here...

---
SESSION_ID: 019a7247-ac9d-71f3-89e2-a823dbd8fd14

Resume Session

# Resume with codex backend
codeagent-wrapper --backend codex resume <session_id> - <<'EOF'
<follow-up task>
EOF

# Resume with specific backend
codeagent-wrapper --backend claude resume <session_id> - <<'EOF'
<follow-up task>
EOF

Parallel Execution

Default (summary mode - context-efficient):

codeagent-wrapper --parallel <<'EOF'
---TASK---
id: task1
backend: codex
workdir: /path/to/dir
---CONTENT---
task content
---TASK---
id: task2
dependencies: task1
---CONTENT---
dependent task
EOF

Full output mode (for debugging):

codeagent-wrapper --parallel --full-output <<'EOF'
...
EOF

Output Modes:

  • Summary (default): Structured report with changes, output, verification, and review summary.
  • Full (--full-output): Complete task messages. Use only when debugging specific failures.

With per-task backend:

codeagent-wrapper --parallel <<'EOF'
---TASK---
id: task1
backend: codex
workdir: /path/to/dir
---CONTENT---
analyze code structure
---TASK---
id: task2
backend: claude
dependencies: task1
---CONTENT---
design architecture based on analysis
---TASK---
id: task3
backend: gemini
dependencies: task2
---CONTENT---
generate implementation code
EOF

Concurrency Control: Set CODEAGENT_MAX_PARALLEL_WORKERS to limit concurrent tasks (default: unlimited).

Environment Variables

  • CODEX_TIMEOUT: Override timeout in milliseconds (default: 7200000 = 2 hours)
  • CODEAGENT_SKIP_PERMISSIONS: Control Claude CLI permission checks
    • For Claude backend: Set to true/1 to add --dangerously-skip-permissions (default: disabled)
    • For Codex/Gemini backends: Currently has no effect
  • CODEAGENT_MAX_PARALLEL_WORKERS: Limit concurrent tasks in parallel mode (default: unlimited, recommended: 8)

Invocation Pattern

Single Task:

Bash tool parameters:
- command: codeagent-wrapper --backend <backend> - [working_dir] <<'EOF'
  <task content>
  EOF
- timeout: 7200000
- description: <brief description>

Note: --backend is required (codex/claude/gemini)

Parallel Tasks:

Bash tool parameters:
- command: codeagent-wrapper --parallel --backend <backend> <<'EOF'
  ---TASK---
  id: task_id
  backend: <backend>  # Optional, overrides global
  workdir: /path
  dependencies: dep1, dep2
  ---CONTENT---
  task content
  EOF
- timeout: 7200000
- description: <brief description>

Note: Global --backend is required; per-task backend is optional

Critical Rules

NEVER kill codeagent processes. Long-running tasks are normal. Instead:

  1. Check task status via log file:

    # View real-time output
    tail -f /tmp/claude/<workdir>/tasks/<task_id>.output
    
    # Check if task is still running
    cat /tmp/claude/<workdir>/tasks/<task_id>.output | tail -50
    
  2. Wait with timeout:

    # Use TaskOutput tool with block=true and timeout
    TaskOutput(task_id="<id>", block=true, timeout=300000)
    
  3. Check process without killing:

    ps aux | grep codeagent-wrapper | grep -v grep
    

Why: codeagent tasks often take 2-10 minutes. Killing them wastes API costs and loses progress.

Security Best Practices

  • Claude Backend: Permission checks enabled by default
    • To skip checks: set CODEAGENT_SKIP_PERMISSIONS=true or pass --skip-permissions
  • Concurrency Limits: Set CODEAGENT_MAX_PARALLEL_WORKERS in production to prevent resource exhaustion
  • Automation Context: This wrapper is designed for AI-driven automation where permission prompts would block execution

Recent Updates

  • Multi-backend support for all modes (workdir, resume, parallel)
  • Security controls with configurable permission checks
  • Concurrency limits with worker pool and fail-fast cancellation
