SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Prevents agents from jumping to external web or fresh research before checking the brain’s existing knowledge, ensuring citations and context stay consistent.

Core Features & Use Cases

  • Brain-first compliance check: Always starts with gbrain search so existing context is resolved before any negation-based or “NOT from elsewhere” reasoning.
  • Correct fallback behavior: Uses an external fallback (e.g., perplexity) only after confirming the brain search returned empty.
  • Body-order robustness: Validates that a reference appearing earlier in the response body is treated as compliant even when negation-prose appears afterward.

Quick Start

Use the skill to answer a research request by first searching the brain and only falling back to an external source if the brain has no relevant results.

FAQPage Schema
How do I ensure a research workflow checks brain context before external web search?▼

To ensure a research workflow checks brain context first, configure the agent to start with gbrain search before any negation reasoning. This enforces brain-reference-first behavior, preventing external web search until existing knowledge is confirmed empty.

What happens when gbrain search returns empty results during agent retrieval?▼

When gbrain search returns empty results, the workflow applies a fallback strategy by triggering a fresh retrieval model like perplexity. This ensures the agent can still fetch external data only after internal brain context is fully exhausted.

How does body-order compliance checking work with negation prose?▼

Body-order compliance checking validates that a reference appearing earlier in the response body is treated as compliant even when negation prose appears afterward. This position-relative logic ensures citations preceding negation statements resolve correctly.

Why does my agent skip existing knowledge and jump to external web search?▼

An agent skips existing knowledge and jumps to web search because it lacks a brain-first compliance check. By starting with gbrain search, the workflow forces the agent to resolve existing context before attempting any external research fallback.

Can I use perplexity as a fallback without checking brain context first?▼

You cannot use perplexity as a fallback without checking brain context first. The workflow requires confirming gbrain search returned empty before optionally falling back to a fresh retrieval model, maintaining citation compliance.
