memory

A way to give an agent additional context from earlier interactions or stored information. It uses an AIContextProvider attached to an agent thread.

In plain words
What is it for?
Use it to run custom logic before and after inference, add context to requests, and inspect messages sent to and produced by a C# agent.
Why use it?
It helps the agent use relevant context across interactions instead of treating every request as isolated.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

memory scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Origin

This is a copy

100% identical to memory — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

Adding Memory to an Agent

::: zone pivot="programming-language-csharp" This tutorial shows how to add memory to an agent by implementing an AIContextProvider and attaching it to the agent.

[!IMPORTANT] Not all agent types support AIContextProvider. This step uses a ChatClientAgent, which does support AIContextProvider.

Prerequisites

For prerequisites and installing NuGet packages, see the Create and run a simple agent step in this tutorial.

Create an AIContextProvider

AIContextProvider is an abstract class that you can inherit from, and which can be associated with the AgentThread for a ChatClientAgent. It allows you to:

  1. Run custom logic before and after the agent invokes the underlying inference service.
  2. Provide additional context to the agent before it invokes the underlying inference service.
  3. Inspect all messages provided to and produced by the agent.

Pre and post invocation events

The AIContextProvider class has two methods that you can override to run custom logic before and after the agent invokes the underlying inference service:

  • InvokingAsync - called before the agent invokes the underlying inference service. You can provide additional context to the agent by returning an AIContext object. This context will be merged with the agent's existing context before invoking the underlying service. It is possible to provide instructions, tools, and messages to add to the request.
  • InvokedAsync - called after the agent has received a response from the underlying inference service. You can inspect the request and response messages, and update the state of the context provider.

Serialization

AIContextProvider instances are created and attached to an AgentThread when the thread is created, and when a thread is resumed from a serialized state.

The AIContextProvider instance might have its own state that needs to be persisted between invocations of the agent. For example, a memory component that remembers information about the user might have memories as part of its state.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

memory is an agent published in the GitHub repository managedcode/dotPilot (23 stars, last pushed 4mo ago), licensed MIT. It adds 13 tokens to every session and 3,484 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. It is 100% identical to memory, differing in 0 lines, and is treated as a copy.
