Mastra Foundation

Use when building a TypeScript agent framework or workflow engine — snapshot-persisted suspend/resume workflow DAGs, state-reader nested path navigation, agent-loop snapshot pruning, run-scope serialization boundary, resumable stream replay caching, agent tool memory isolation, Graph RAG serialization, LLM relevance scoring, ACP tool adapters, and the control-flow execution kernel (parallel/conditional/loop/foreach handlers with durable-engine hooks).

mastra: TypeScript Agent Framework Foundation

Foundation contract

This is a cold, source-specific foundation, not an operational procedure. It is historical, revision-pinned evidence rather than timeless guidance. Current project source, tests, requirements, and runtime behavior outrank this projection and decide what ships.

Provenance and revision

Source record: mastra; portable upstream identity, license, coverage caveats, and retrieval history are preserved in the index.
Recorded revision: main@502653550fb45d8e72dfdd57732161f9176dbcf2.
Full provenance, coverage caveats, boundaries, and preserved evidence: references/index.md.

Topic map

Representative topics: Workflow Engine & State Machine; Snapshot Persistence & Pruning; Runtime State & Wire Boundary; Stream Plane; Agent Runtime & Memory Isolation; External Events; Graph RAG & Reranking; Protocol & SDK Bridges.
Scope and retrieval questions: references/index.md#use-this-for.
Complete capsule chooser: references/index.md#load-the-matching-source-dump.
Detailed grouped map: references/index.md#capsule-map.
Source limitations and portability boundaries: references/index.md#boundaries.

Retrieval

Open the index, choose one capsule matching the active question, and load only that capsule. Revalidate its cited source and revision before relying on it. Do not bulk-load the inventory, treat historical claims as current truth, or apply this foundation as a procedure.
