Interface: AgentMemoryProvider

Defined in: packages/agentos/src/api/agent.ts:92

Provider hook interface consumed by agent() for memory integration.

When provided on the agent config, getContext is called before each LLM generation to inject retrieved memory into the system prompt, and observe is called after each turn to encode the exchange for future recall. Both hooks are optional — implementations may choose to provide read-only or write-only memory behavior.

Auto-wires on every agent call path as of AgentOS 0.2.0: direct agent.stream() / .generate() and agent.session().send() / .stream() all invoke the hooks when the provider is present.

Properties​

getContext()?​

optional getContext: (text, opts?) => Promise<{ contextText?: string; } | null>

Defined in: packages/agentos/src/api/agent.ts:102

Retrieve a memory context block to prepend to the system prompt.

Parameters​

text​

string

The user input for the current turn.

opts?​

Retrieval options. tokenBudget caps the memory block size.

tokenBudget?​

number

Returns​

Promise<{ contextText?: string; } | null>

An object whose contextText (when present) is injected as a system message before the LLM call. Returning null or an object without contextText skips injection.

observe()?​

optional observe: (role, text) => Promise<void>

Defined in: packages/agentos/src/api/agent.ts:117

Record an observation of a turn exchange.

Invoked twice per turn (role: 'user' with the input, then role: 'assistant' with the reply) as fire-and-forget. Rejections are swallowed so memory-backend errors do not break generation.

Parameters​

role​

Whether the content came from the user or assistant.

"user" | "assistant"

text​

string

Plain text content of the turn.

Returns​

Promise<void>
