Behavioral validation forged in, not bolted on.

Forge is an autonomous behavioral validation swarm skill for Claude Code that combines BDD behavioral verification, 7 behavioral validation gates, confidence-tiered learning, topological governance, and self-healing fix loops. It spawns 8 specialized agents that work in parallel to verify, test, fix, and commit - continuously - until every Gherkin scenario passes and every behavioral validation gate clears.

• 8 specialized agents working in parallel with cost-optimized model routing
• Gherkin behavioral specifications as the single source of truth
• 7 behavioral validation gates: Functional, Behavioral, Coverage, Security, Accessibility, Resilience, Contract
• 12 topological governance specifications (§1.1–§1.12) - mathematical foundations for autonomous behavioral validation
• Confidence-tiered fix patterns (Platinum/Gold/Silver/Bronze) with Nash Equilibrium convergence
• Defect prediction based on historical failure data and file changes
• Chaos/resilience testing with controlled failure injection
• Cross-context dependency awareness with cascade re-testing and sheaf cohomology consistency
• Shared types and cross-cutting validation across bounded contexts
• Agent-optimized ADRs with MUST/MUST NOT constraints and verification commands
• Visual regression testing with pixel-by-pixel comparison
• Architecture-agnostic - monolith, microservices, monorepo, mobile+backend
• Optional Agentic QE integration for enhanced pattern search, security scanning, and more
• External-only mocking - mock third-party services, never internal code (production-validated policy)
• Spec drift detection - detects when Gherkin specs and implementation diverge
• LLM-as-Judge meta-review - second-model evaluation with Anti-Echo-Chamber guarantee
• Self-reflection gate - Bug Fixer asks "What could go wrong?" before committing
• Hallucination Gate - deterministic pre-LLM boundary (AST resolution, contract hash, mocking detection)
• Agent criticality scoring - bottleneck detection via Dirichlet energy and automatic optimization
• Narya-proofs - counterfactual verification proving fix necessity and sufficiency
• Property-based testing - generate 1000+ test cases from invariants
• Mutation testing - inject bugs to verify test effectiveness
• Blake3 witness chain - cryptographic tamper-evident audit trail for gate verdicts
• Infrastructure readiness markers - specify formally, implement pragmatically, upgrade transparently

"DONE DONE" means: the code compiles AND the product behaves as specified. Every Gherkin scenario passes. Every behavioral validation gate clears. Every dependency graph is satisfied.

1. Phase 0 - Backend setup (build, run, health check, seed data)
2. Phase 1 - Behavioral specification & architecture records (Gherkin specs, ADRs)
3. Phase 2 - Contract & dependency validation (schemas, shared types, cross-cutting)
4. Phase 3 - Swarm initialization (load patterns, predictions, confidence tiers)
5. Phase 4 - Spawn 8 autonomous agents in parallel
6. Phase 5 - Behavioral validation gates evaluation (7 gates after every fix cycle, BFT consensus ≥5/7)

Forge v1.2.0 introduces 12 formal topological governance specifications (§1.1–§1.12) that provide mathematical foundations for autonomous behavioral validation. Production heuristics from v1.1.0 - criticality scoring, regression tracking, blocking gates - are now anchored to formal mathematical equivalents.

Every specification is operational today. Infrastructure readiness markers define the path from "correct" to "correct and fast":

If no configuration files are present, Forge auto-discovers the project structure on first run.

Forge optionally integrates with Agentic QE via MCP for enhanced capabilities:

All AQE features are additive. Forge works identically without AQE installed.
