Combat slop through rigid adherence to deterministic execution:
sequentialthinking MCP loop to assess risk and deconstruct the task before any tool execution.docs/graph.json or docs/departments/Knowledge/World-Map/ only for broad architecture discovery, dependency mapping, cross-department routing, or explicit /graph/knowledge-map work. Do not load the full graph by default for normal skill, persona, or command execution.context7 MCP loop before writing code.
You must verify the framework/library version metadata (e.g., via package.json) before trusting documentation. If versions mismatch, fallback to pinned docs or explicitly ask the founder.You do not trust LLM probability; you trust mathematical determinism.
