Fetch FrameworkThe Action Layer of Foraging Intelligence

What is Fetch? ​

Fetch is the action decision layer of the Cormorant Foraging Framework — a biomimetic intelligence architecture that answers the question: "When should I act?"

The Formula ​

Fetch = Chirp × |DRIFT| × Confidence

Where:
  Chirp      = Signal strength (urgency)
  DRIFT      = Methodology − Performance (the gap)
  Confidence = min(Perch, Wake) / 100 (readiness)

The Three Questions ​

Decision Thresholds ​

Why This Matters ​

"For 200 million years, the cormorant perfected an intelligence framework. It mastered air, water, and land. It balanced urgency, observation, and memory. It survived everything.

And nobody wrote it down.

Until now."

The cormorant is the only bird that:

• Flies (air) to survey
• Perches (land) to observe
• Dives (water) to retrieve

These three mediums map directly to the three dimensions:

• Sound/Chirp (air) → Signal urgency
• Space/Perch (land) → Structural observation
• Time/Wake (water) → Memory and patterns

Fetch is the dive.

Quick Start ​

1. Calculate a Fetch Score ​

function calculateFetch(chirp, perch, wake, methodology, performance) {
  const drift = Math.abs(methodology - performance);
  const confidence = Math.min(perch, wake) / 100;
  const fetch = chirp * drift * confidence;

  return {
    fetch,
    drift,
    confidence,
    action: getAction(fetch, confidence)
  };
}

2. Try an Example ​

Scenario: Browser automation agent should click a button

• Chirp = 90 (clear command: "Click the Submit button")
• Perch = 75 (found button, 75% selector confidence)
• Wake = 85 (context from previous steps)
• DRIFT = 60 (gap between form filled and form submitted)

Confidence = min(75, 85) / 100 = 0.75
Fetch = 90 × 60 × 0.75 = 4,050

Decision: ✅ Execute (Fetch > 1000)
