# Slack skill
+ > **HEADLESS IS FORBIDDEN. VISIBLE FOREGROUND EXECUTION ONLY.** Every command, automated test, diagnostic, script, build, agent and browser must run in a visible foreground window on Angela's real desktop. Use forked CMD/PowerShell windows, `execute_forked_window: true`, and `headless: false`. Monitor live; if visibility cannot be confirmed, do not run. Read the [mandatory execution policy](../../../../TestsVisiblesAndVisibleExecutionFromClaude2Codex.md).

Use the Slack Web API. `SLACK_BOT_TOKEN` must be in env.
