Module agent 

AI coding agent detection for agent-specific profiles.

This module detects which AI coding agent is invoking dcg, enabling per-agent trust levels and configuration overrides.

Detection Methods

1. Environment variables (primary): Most agents set identifying env vars
2. Explicit flag: --agent=<name> CLI flag for manual override
3. Parent process inspection (fallback): Check process tree for agent names

Supported Agents

• Claude Code: CLAUDE_CODE=1 or CLAUDE_SESSION_ID env var
• Augment Code: AUGMENT_AGENT=1 or AUGMENT_CONVERSATION_ID env var
• Aider: AIDER_SESSION=1 env var
• Continue: CONTINUE_SESSION_ID env var
• Codex CLI: CODEX_CLI=1 env var
• Gemini CLI: GEMINI_CLI=1 env var
• Copilot CLI: COPILOT_CLI=1 or COPILOT_AGENT_START_TIME_SEC env var

Usage

use destructive_command_guard::agent::{Agent, detect_agent};

let agent = detect_agent();
println!("Detected agent: {}", agent);
