AI agents are excellent at generating code, but they are often "stateless" background workers. **SpecAgnt** transforms them into digital citizens with identity, memory, and architectural responsibility.

SpecAgnt is a kit of 31 templates that defines the full product lifecycle. It isn't just a doc generator; it's a validation engine.

**1. The "Spec-First" Workflow**

SpecAgnt forces a rigorous 7-step sequence: Vision → Research → Architecture → Security → Operations → Validation. This prevents "hallucinated" features by ensuring every API endpoint traces back to a PRD user story.

**2. Agent Character & Lifecycle (AC/AL)**

Using a DNA seed derived from system entropy, the agent generates a unique persona with 10 mutable traits (Curiosity, Humor, Neuroticism, etc.). These traits affect the agent's autonomous "Thought" phase and its communication style.

**3. Bidirectional Drift Detection**

SpecAgnt continuously compares your codebase (Routes, DB Schemas, Middleware) against your `.md`

specifications. If the code diverges from the docs, the agent detects the "drift" and proposes a remediation spec.

**4. The Agent Manifest (AX)**

By serving a machine-readable manifest at `/.well-known/ai-manifest`

, your project becomes an active participant in the AI ecosystem. It tells other agents exactly what tools, resources, and auth methods are available.
