methodos documentation

Build with
procedural memory.

Methodos is a typed Python library and optional HTTP service for storing, retrieving, and evaluating reusable agent procedures.

quick start

Install it, then explore the graph.

Start locally with SQLite. Add Postgres only when the service needs shared durable state across replicas.

ProceduralGraph

Validated nodes, edges, attributes, and graph invariants.

AgentState

Bounded context passed between the host solver and adapter.

Solver / LLMClient

Structural async protocols that keep providers replaceable.

Repository

Persistence seam for SQLite, Postgres, and test doubles.
