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
• Multi-agent orchestration workflows (codex for code, gemini for UI, codex-review for review)

Usage

HEREDOC syntax (recommended):

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

Sanity check (verify CLI is current):

codeagent-wrapper --version
codeagent-wrapper --help

With backend selection:

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

Simple tasks:

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

Backends

⚠️ opencode backend does NOT support stdin input; prompts are passed as CLI args. Prefer short prompts + @path file references.

Backend Selection Guide

Codex (default, recommended for code + review):

• Deep code understanding and complex logic analysis
• Code review and quality assessment
• Orchestration and coordination tasks
• Example: "Review the implementation in @src/api for security issues and suggest improvements"

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 (recommended for UI):

• UI component scaffolding and layout prototyping
• Design system implementation with style consistency
• Interactive element generation with accessibility support
• Frontend development (React, Vue, HTML/CSS)
• Example: "Create a responsive dashboard layout with sidebar navigation and data visualization cards"

Multi-Agent Orchestration Pattern

For orchestrated workflows, use this backend assignment:

Backend Switching:

• Use codex for code implementation, gemini for UI, codex for review
• 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 (optional): Select AI backend (codex/claude/gemini, default: codex)
  • Note: Claude backend only adds --dangerously-skip-permissions when explicitly enabled
• --skip-permissions / --dangerously-skip-permissions: For Claude backend only; disables permission prompts (use sparingly)
• --tmux-session (optional): Enable tmux visualization mode for parallel execution
• --tmux-attach (optional): Attach to tmux session after completion
• --tmux-no-main-window (optional): Remove default main window in tmux sessions
• --window-for (optional): Single-task mode only; route output to an existing task window
• --state-file (optional): Path to AGENT_STATE.json for real-time status updates
• --review (optional): Mark tasks as review tasks for state updates
• --cleanup: Remove old wrapper logs

Return Format

Agent response text here...

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

Resume Session

# Resume with default backend
codeagent-wrapper 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 (orchestration pattern):

codeagent-wrapper --parallel --tmux-session orch-session --state-file AGENT_STATE.json <<'EOF'
---TASK---
id: task1
backend: codex
workdir: /path/to/dir
target_window: backend
---CONTENT---
Implement user authentication module
---TASK---
id: task2
backend: gemini
workdir: /path/to/dir
target_window: frontend
---CONTENT---
Create login form component with validation
---TASK---
id: task3
backend: codex
dependencies: task1, task2
target_window: review
---CONTENT---
Review implementation for security issues
EOF

Task metadata fields:

• id: Unique task identifier (required)
• backend: AI backend to use (codex/claude/gemini)
• workdir: Working directory for the task
• dependencies: Comma-separated task IDs that must complete first
• target_window: tmux window name for grouping related tasks

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_ASCII_MODE: Use ASCII symbols instead of Unicode (PASS/WARN/FAIL)
• 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_OPENCODE_AGENT: OpenCode agent name (used by --backend opencode)
• CODEAGENT_OPENCODE_MODEL: OpenCode model name (used by --backend opencode)
• CODEAGENT_MAX_PARALLEL_WORKERS: Limit concurrent tasks in parallel mode (default: unlimited, recommended: 8)

🔒 CODEX_BYPASS_SANDBOX=true (Codex backend): bypasses approvals/sandbox in Codex CLI. Use only in trusted environments.

Invocation Pattern

Single Task:

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

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>

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

• tmux integration: --tmux-session flag for visual parallel execution
• State file support: --state-file flag for AGENT_STATE.json real-time 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
