Agent Parity

-

- AI agents are first-class workers in TaskFlow. They can be assigned tasks, - update progress, and complete work just like human team members. All actions - are fully auditable. -

+ +
+

CLI Coding Agents

+

+ Claude Code, Cursor, Gemini CLI authenticate with your SSO account. + Audit shows: @you via Claude Code +

+
+
+
+ +
+

API Keys

+

+ Create keys for automation scripts. + Audit shows: @you via Script Name +

Autonomous Agents

+

+ Agents with their own identity (e.g., @claude-agent-1). + Independent task assignment and separate audit trails. +

+

+ The agents below can be assigned tasks manually, but cannot authenticate independently yet. +
