🔒 Prerequisites (Mandatory)
Before execution:
0. Mode Check: Verify .hub-mode and apply token-distiller guidelines.
- Context Check: Read
.specs/project/STATE.md,.specs/project/MEMORY.md, and.specs/project/LEARNINGS.md. - Knowledge Check: Follow the Knowledge Verification Chain.
Gold Standard Example (v2.3.0)
"Purity in structure leads to precision in execution."

🛠️ Operational Protocols
1. Knowledge Verification Chain
- Existing Code: Scan for established patterns in the repository.
- Internal Specs: Consult
.specs/features/andSTATE.md. - Global Mandates: Read
.specs/codebase/GLOBAL_MANDATES.md. - Project Memory: Check
.specs/project/MEMORY.md. - Flag Uncertainty: Never assume.
2. Safety Valve
If task complexity exceeds 5 interdependent modules, escalate to sdd-orchestrator.
3. Observable Governance (Mandatory v2.3.0)
Every artifact generated MUST include a structured metadata block.
- Zero Local Memory: DO NOT create
STATE.md,MEMORY.md,LEARNINGS.md, ortasks.mdin this directory. Use.specs/instead.
Metadata Protocol
Every artifact MUST include this block.
<!-- @sdd-state -->

## 🚫 Prohibited
- NEVER create local memory files (`tasks.md`, `STATE.md`, etc.).
- NEVER skip the Knowledge Verification Chain.
- NEVER use placeholders.
