Crate is_ai_agent 

Detect whether the current process is being invoked by an AI coding agent, and identify which one.

Detection order:

1. The proposed standard AGENT env var (see agentsmd/agents.md#136).
2. Tool-specific env vars (CLAUDECODE, CURSOR_AGENT, …).
3. Filesystem signals (e.g. /opt/.devin).

if is_ai_agent::is_ai_agent() {
    // emit structured output
}

if let Some(agent) = is_ai_agent::detect() {
    eprintln!("running under {}", agent.name);
}

Structs

Agent

A detected AI agent and the signal that revealed it.

Enums

AgentId

Canonical identifier for a known agent, or Unknown when an agent is present but its specific identity can’t be determined (e.g. AGENT=1).

Signal

What signal triggered the detection.

Functions

detect

Detect the AI agent, if any.

detect_with

Detection with injectable lookups, useful for tests and for callers that want to consult a captured environment instead of the live process.

is_ai_agent

Returns true if any AI agent signal is present.
