What do people build with it?

USE CASE 1

Let your AI agent recall past bug fixes and workflow patterns without repeating context each time.

USE CASE 2

Install a single skill file so your coding agent starts each session already knowing how you work.

USE CASE 3

Run quietly in the background so it only speaks up when a question needs your personal history.

Requires installing the separate Yansu app to build the memory this skill reads from.

So what is it?

Yansu.skill is a plugin that lets your AI coding agent, such as Claude or Cursor, remember how you personally work, so you do not have to explain your setup and habits again in every new conversation. The skill pairs with a separate app called Yansu that runs on your computer and watches how you work: the decisions you make, the workflows you repeat, and the problems you have run into and solved before. Yansu turns this observation history into organized personal notes stored on your own device. Once you install yansu.skill into your AI agent, the agent can pull up relevant pieces of that stored knowledge when it answers your questions. If you ask about a build that failed, the agent can recall that you hit the same issue weeks earlier and how you fixed it that time. If you ask it to start your staging database, it already knows where your configuration files live and what tends to go wrong the first time it boots. The skill is built around a few clear rules. It only speaks up when a question genuinely needs your personal context, and stays quiet the rest of the time. It is read only, meaning it can pull information from your stored knowledge but never writes anything back. All the data it draws on stays on your own machine and is never sent to an external server. Installing it takes one prompt: you ask your AI agent to fetch the SKILL.md file from this repository and save it to the folder where the agent looks for skills. After that one step, the agent starts every new session already knowing your history instead of starting from zero.

Copy-paste prompts

Prompt 1

Install the Yansu skill for me by fetching https://raw.githubusercontent.com/Isoform/yansu-skill/main/SKILL.md and saving it to my skills directory.

Prompt 2

/yansu why did that build fail again, the auth one?

Prompt 3

/yansu spin up the staging database

Prompt 4

Explain how Yansu.skill decides when to use my personal context versus staying silent.
