forge

claude

Codebase-aware specification engine. Runs a grounded interview that captures implicit facts as A-AUTO-NNN entries, emits typed Global Invariants / State Transitions / Contracts tables, runs an adversarial spec review at R3.5, and writes a foundry-ready spec with version frontmatter — locked, classified, and verifiable. Brownfield runs produce a flow delta against the existing system; greenfield runs produce an end-state spec; cosmetic runs skip flow mapping. Forge plans. Foundry builds.
