3.2.0 — Meet Hephaestus 🔨

Highlights

🔥 Hephaestus: The Legitimate Craftsman Agent

In Greek mythology, Hephaestus was the god of forge, fire, metalworking, and craftsmanship—the divine blacksmith who crafted weapons for the gods.

Meet our new autonomous deep worker: Hephaestus (GPT 5.2 Codex Medium).

Why "Legitimate"? When Anthropic blocked third-party access citing ToS violations, the community started joking about "legitimate" usage. Hephaestus embraces this irony—he's the craftsman who builds things the right way.

Key Characteristics:

• Goal-Oriented: Give him an objective, not a recipe. He determines the steps himself.
• Explores Before Acting: Fires 2-5 parallel explore/librarian agents before writing a single line of code.
• End-to-End Completion: Doesn't stop until the task is 100% done with evidence of verification.
• Pattern Matching: Searches existing codebase to match your project's style—no AI slop.
• Legitimate Precision: Crafts code like a master blacksmith—surgical, minimal, exactly what's needed.

Inspired by AmpCode's deep mode—autonomous problem-solving with thorough research before decisive action.
