Hey did the memory implementation changed on the 0.5.0? I don't see that facts are loaded on the prompt maybe I'm missing something

[Andrey Bragin]

Hi, I don’t recall any major changes. It would be helpful if you can share a relevant code snippet

[Sergi Aguilar]

Hey sorry for the late answer. Here's the code snippet I used as an example. I attached two traces, one with 0.4.1 and the other with 0.5.0. As you can see on the screenshot taken with 0.5.0 the facts are not loaded

suspend fun main() {
    // Memory configuration
    val localMemory = LocalFileMemoryProvider(
        config = LocalMemoryConfig("user-traits-memory"),
        storage = SimpleStorage(JVMFileSystemProvider.ReadWrite),
        fs = JVMFileSystemProvider.ReadWrite,
        root = Path("examples/kotlin/facts-store-kotlin/memory")
    ).also {
        runBlocking {
            it.save(
                fact = SingleFact(
                    concept = Concept(
                        "personality-trait",
                        "A personality trait of every user",
                        factType = FactType.SINGLE
                    ),
                    value = "Has no sense of humour, if they ask for a joke they expect an interesting fact instead",
                    timestamp = DefaultTimeProvider.getCurrentTimestamp()
                ),
                subject = MemorySubject.Everything,
                scope = MemoryScope.Agent("fact-agent"),
            )
        }
    }

    val strategy = strategy("fact-agent", toolSelectionStrategy = ToolSelectionStrategy.NONE) {

        val loadAll by nodeLoadAllFactsFromMemory<String>(
            name = "loadMemoryNode",
            subjects = listOf(MemorySubject.Everything)
        )

        val messageNode by node<String, String>("messageNode") {
            llm.writeSession {
                updatePrompt {
                    user(it)
                }
                requestLLMWithoutTools().content
            }
        }

        edge(nodeStart forwardTo loadAll)
        edge(loadAll forwardTo messageNode)
        edge(messageNode forwardTo nodeFinish)
    }

    // populate the openAI API key here.
    val agent = AIAgent(
        promptExecutor = simpleOpenAIExecutor(API_KEY),
        strategy = strategy,
        agentConfig = AIAgentConfig(
            prompt = prompt("fact-agent") {},
            model = OpenAIModels.Chat.GPT5Nano,
            maxAgentIterations = 10
        ),
        toolRegistry = ToolRegistry.EMPTY
    ) {
        install(AgentMemory) {
            memoryProvider = localMemory
        }
        install(OpenTelemetry) {
            addLangfuseExporter(
                langfuseUrl = "<http://localhost:33333>",
                langfusePublicKey = PUBLIC_KEY,
                langfuseSecretKey = PRIVATE_KEY,
            )
            setVerbose(true)
        }
    }

    agent.run("Tell me an interesting joke")
}

Thanks, I can reproduce it. We will take a look at this

thanks!
