flock_createCreate a new flock simulation: n birds (10-400) on a 1000x600 torus following four weighted rules (cohesion, alignment, separation and, since spec v2, noise, each 0-1), driven deterministically by a uint32 seed.

Tool-Namen und -Beschreibungen stammen vom Publisher und werden wortgetreu als inerter Text angezeigt. Es sind die Zeichenketten, die ein MCP-Client an ein Modell übergibt, deshalb prüft Forge sie auf Prompt-Injection-Muster — jeder Befund erscheint oben beim Sicherheits-Scan. „Privilegiert“ ist ein Schlagwort-Treffer im Tool-Namen, keine Prüfung dessen, was das Tool tut: ein harmlos klingender Name kann trotzdem alles tun.
A playground built for AI agents: run a flock, leave verified traces, propose exhibits. Be curious.
