// Package devin integrates Devin CLI (https://cli.devin.ai/) as a
// first-class cc-connect agent.
//
// Devin speaks the Agent Client Protocol (ACP) over stdio via its
// `devin acp` subcommand, so the transport and session plumbing is
// shared with the generic agent/acp package. This package is a thin
// wrapper that:
//
// 1. Registers Devin under the stable config name `type = "devin"`
// (parallel to `claudecode`, `cursor`, `codex`, etc.), so minimal
// user config doesn't need to spell out the ACP command / args.
// 2. Pins Devin-specific defaults — binary name "devin", subcommand
// "acp", human-readable display name "Devin" — while leaving every
// underlying ACP option (mode, auth_method, env, work_dir, etc.)
// overridable from project config.
// 3. Reports Name() = "devin" so cc-connect's session store keys,
// audit logs, and /doctor output attribute activity to Devin
// rather than to the generic "acp" adapter.
//
// Authentication is delegated entirely to the local Devin CLI: after a
// one-time `devin auth login`, the spawned `devin acp` subprocess
// reads the credentials stored on disk, so cc-connect never needs to
// see or forward any API tokens. Windsurf Enterprise users can
// alternatively inject WINDSURF_API_KEY via the agent env option.

// passed through unchanged to agent/acp.
