Pattern Library

Reusable solutions extracted from real GE agent work. Curated by Annegreet (Knowledge Curator).

How Patterns Work in GE

  1. Discovery — Annegreet analyzes agent sessions, identifies novel solutions and struggles
  2. Extraction — Distills reusable insights from session-specific work
  3. Validation — Patterns are used in subsequent projects, refined through use
  4. Graduation — Proven patterns become standards (see Standards)

The learning pipeline automates discovery and extraction. See Agent System Pitfalls for the learning pipeline details.

Architecture Decision Records

Pattern Quality Standards

Every pattern must: - Trace to real GE sessions/deployments (evidence-based) - Include problem, solution, and reasoning - Document trade-offs: when to use AND when NOT to use - Include code examples where applicable - Cross-reference related patterns

Adding Patterns

Patterns come from Annegreet's session analysis or from agent/human suggestions. To suggest a pattern, write to ge-ops/system/outbox/pending/ with a pattern proposal.

Archived Pattern Library

The full pre-migration pattern library (15 patterns with detailed documentation) is archived at archive/pre-wiki-brain/20260215/patterns/README.md. Individual pattern files are in the same directory.

These will be migrated into the wiki as individual pages in a future update.
