Skills

Create reusable guidance packages and attach them to your agents.

Skills are reusable guidance assets.

Each skill includes:

  • a name
  • a description
  • a SKILL.md
  • optional supporting files

From the Skills UI, you can:

  • create a new skill
  • import a skill from GitHub
  • open a skill and browse its files
  • edit custom skills directly in the app
  • upload additional files into a custom skill
  • attach selected skills to an agent from the agent form

Built-in skills can be read-only. Custom skills can be edited or deleted.

The Skills tab starts with create and import actions. If your workspace has no skills yet, Cofounder shows an empty state with those same actions.

Use Skills In Prompts

You can add a skill to a prompt by typing / in the prompt composer and choosing a skill from the menu.

Selected skills appear inline in your message. Cofounder uses those skills as guidance for that specific request, without requiring you to edit the agent first.

You can include more than one skill in the same prompt. For example:

/research compare these competitors, then /copywriter turn the findings into a landing page section

When To Use A Skill

Use a skill when:

  • the guidance should be shared across multiple agents
  • the instructions are deep enough that they deserve their own file
  • you want supporting reference files, not just one text box

Use agent custom instructions when the guidance is specific to one agent and does not need its own reusable package.
