Field notes

A working library of patterns and notes for building RAG systems and intelligent workflows.

Start with the pattern catalog, then explore patterns and notes below.

Suggested flow

catalog entry → patterns → notes (longer framing)

Patterns — catalog-style entries in a Fowler-style pattern spirit; titles link to living drafts. Notes — essays and framing; not every note becomes a pattern card.

Three layers: Glossary — shared vocabulary; Patterns — applied by domain (RAG is the first catalog set, not the boundary); Notes — cross-cutting thinking.

Note shapes

Sequence notes — flow and dependency (how work unfolds). Constraint notes — interfaces and enforcement (what must hold). Framing notes — correct how you interpret the problem before you execute. Glossary — shared terms; definitions, not prescriptions.

Several entries are still draft; titles and summaries evolve as the catalog grows.

Pattern catalog (RAG as first set)

RAG is the first pattern set: start with retrieval, then expand the catalog into broader system patterns.

Step 2 of 3

Patterns

Catalog entries in a Fowler-style pattern spirit, applied to RAG and intelligent systems.

Structured entries; titles link to living drafts. Pair with Notes for longer framing and Glossary for shared vocabulary.

Step 3 of 3

Notes

Essays and framing — not every note becomes a pattern card. Pair with Glossary for shared terms.

Glossary

Atomic definitions used across patterns and notes—language first, not system prescriptions.
