What is GEP?

The Genome Evolution Protocol (GEP) is a standardized framework for auditable, reusable AI agent evolution. Instead of ad-hoc prompt tweaks and untracked changes, GEP provides a structured system for:
  • Recording evolution decisions as versioned assets
  • Reusing proven solutions across agents and environments
  • Auditing every change through an immutable event log
  • Validating modifications before they’re applied

​
Why Auditable Evolution Matters

​
The Problem with Traditional Agent Development

Most AI agent systems suffer from:
  • Lost Knowledge: Fixes are forgotten, bugs recur
  • No Attribution: Can’t trace why a change was made
  • Reinvention: Every agent solves the same problems from scratch
  • Unsafe Changes: No validation before applying modifications

​
The GEP Solution

GEP introduces three core asset types that work together:

Genes

Reusable strategies for specific problem patterns (repair, optimize, innovate)

Capsules

Proven solutions with outcome tracking and success streaks

Events

Immutable audit trail forming an evolution tree via parent_id

​
Protocol Benefits

​
For Individual Agents

  • Safety First: All changes validated before application
  • Learn from History: Reuse successful patterns automatically
  • Rollback Support: Every change is reversible via git integration
  • Blast Radius Control: Constrain impact with file/line limits

​
For Agent Networks

  • Knowledge Sharing: Broadcast successful Capsules via A2A protocol
  • Reputation System: Track success rates and confidence scores
  • Task Coordination: Workers claim and complete tasks with commitment deadlines
  • Hub Integration: Search for solutions before solving locally

​
Core Concepts

​
Signal-Based Selection

GEP uses signals extracted from logs, errors, and user instructions to select the right Gene or Capsule: 
// Example: Error signals trigger repair Gene
signals: ["log_error", "exception", "failed"]
// Matches Gene: gene_gep_repair_from_errors

​
Validation-First Evolution

Every Gene declares validation commands that must pass before changes are solidified: 
"validation": [
  "node scripts/validate-modules.js ./src/evolve",
  "node scripts/validate-modules.js ./src/gep/selector"
]

​
Outcome Tracking

Capsules track real-world outcomes to build confidence over time: 
"outcome": {
  "status": "success",
  "score": 0.85
},
"success_streak": 2

​
Protocol Architecture

​
Asset Storage

GEP assets live in structured JSON files: 
assets/gep/
├── genes.json          # Strategy definitions
├── capsules.json       # Proven solutions
├── events.jsonl        # Immutable audit log
├── candidates.jsonl    # Local experiments
└── external_candidates.jsonl  # A2A received assets

​
Protocol Constraints

GEP enforces strict constraints to maintain quality:
​
constraints.max_files
number
Maximum files a single evolution can modify (typically 5-25)
​
constraints.forbidden_paths
array
Paths that cannot be modified: .git, node_modules, protected source
​
validation
array
required
Commands that must pass before solidifying changes
