Acontext
Agent Skills as a Memory Layer
Last verified:
What is Acontext?
Acontext is an open-source context data platform for AI agents that helps developers store, observe, and learn from agent runs. It is built around a continuous loop where sessions and multimodal context are captured, tasks are monitored, and successful outcomes are distilled into reusable skills. The platform is designed to make agents more reliable and self-improving over time instead of treating every run as a fresh start.
The product centers on a unified context layer for messages, artifacts, tool calls, memory, and session history. It supports multiple message formats, including OpenAI, Anthropic, and Gemini, and can automatically convert between them. It also offers artifact storage, context editing, session summaries, task tracking, and observability dashboards so teams can inspect what their agents did and why.
Acontext also emphasizes long-term learning through “skill memory.” When tasks succeed, the system can turn those runs into Markdown-based skill files that agents can reuse later. Those skills are readable, editable, portable, and shareable across agents and frameworks, which makes the system appealing for teams building workflows that should improve with experience.
The platform is aimed at developers building production AI agents, autonomous workflows, and agentic applications. It provides SDKs, APIs, a dashboard, and self-hosting options, so it can fit both cloud-based and local setups. It is especially relevant for teams that need better context management, observability, and reusable knowledge across agent runs.
Acontext pricing
Pricing model: Freemium
The website says there is a free account option on the Acontext Dashboard for onboarding and API key setup. It also offers a managed cloud platform and a self-hosted open-source stack that can be installed on your own infrastructure with a single command. The site does not show detailed paid plan prices on the pages reviewed, but it does show core product capabilities included in the platform: session management, artifact storage, sandbox execution, observability dashboard, context editing, agent skills, task monitoring, prompt-cache stability, session summaries, and API security.

Frequently asked questions about Acontext
What is Acontext used for?
Acontext is used to give AI agents a persistent context layer and a learning loop. It stores sessions, messages, artifacts, tool calls, and memory, then observes agent behavior and turns successful outcomes into reusable skills. The goal is to help agents become more reliable and improve over time instead of repeating the same work from scratch on every run.
How does the skill memory feature work?
Skill memory captures what happens during agent runs, distills useful patterns from successful tasks, and writes them into Markdown skill files. Those files can then be read back by agents through get_skill or get_skill_file, shared across systems, edited by humans, and reused in later runs. The site describes this as a continuous loop of learn from runs, write as Markdown, and reuse anywhere.
Which LLM formats does Acontext support?
Acontext supports OpenAI, Anthropic, and Gemini message formats. The platform also says it can convert between formats automatically, which helps teams move context across different model providers without writing their own adapters or manual conversion logic.
What types of data can Acontext store?
Acontext can store multimodal context, including messages, artifacts, tool calls, memory, files, and session data. Its product pages also highlight S3-backed artifact storage and search features for managing files and directories tied to agent work.
Does Acontext have a dashboard?
Yes, Acontext includes a dashboard for viewing Context, Artifacts, Tasks, and Skills in one place. The docs describe views for metrics, traces, messages, artifacts, tasks, and skills so developers can inspect execution flow, debug behavior, and monitor success rates.
Can Acontext be self-hosted?
Yes, the site says Acontext is open source and self-hostable. It also advertises a one-command install for running the full stack on your own infrastructure, alongside a managed cloud option.
What SDKs are available?
The website lists official Python and TypeScript SDKs with async support. The docs and examples show the Python SDK in use, and the product pages indicate the SDKs are intended to connect agent workflows to sessions, storage, and learning features.
Who is Acontext for?
Acontext is aimed at developers building AI agents, autonomous workflows, and production LLM systems. It is especially useful for teams that need persistent memory, better observability, reusable skills, and a way to make their agents improve from experience.
What is the sandbox feature for?
The sandbox feature lets you execute code in isolated environments. The product page says it is used to run skills, process files, and build workflows securely in containers with full command execution.
What are the main limits of Acontext?
Based on the website, some limitations are that not every listed feature is available yet, pricing details are not fully published on the reviewed pages, and some capabilities may add setup and operational overhead. It also appears most valuable for teams that actually need agent memory, observability, and learning rather than simple one-off chatbot use.
