Use Skills with MuleSoft Vibes
Cloud IDE
Desktop IDE
Skills are reusable instruction sets that MuleSoft Vibes activates only when they apply to your task. Each skill packages guidance and optional resources so MuleSoft Vibes can follow a consistent workflow without loading that material for unrelated prompts.
When your request matches a skill’s description, MuleSoft Vibes uses the use_skill tool to load the full instructions and run them for that task. Unlike workspace rules that stay active across conversations, skills load as needed, which leaves more context available for other work.
Workspace skills are available only in the workspace or project where they’re defined. Global skills are available in every project and workspace.
Skills are always available in MuleSoft Vibes where the feature is supported. You can’t turn it on or off.
Set Up Skills in Your Project
To add workspace skills to a project, add skills under .a4drules/skills/ in your workspace. Each skill is a directory whose name matches the skill. The directory contains a SKILL.md file with the instructions (and optional YAML frontmatter for metadata). You can add supporting material in subfolders such as references/, assets/, or scripts/ inside that skill directory.
Commit .a4drules/skills/ with your project so everyone who uses the repository gets the same skills.
Skills and MCP Tools
Model Context Protocol (MCP) servers expose tools that perform actions, such as generating a flow or calling an API. Skills supply structured instructions and workflows the assistant follows when a task matches the skill. You typically use both: tools carry out operations, while skills guide how and when to apply them for specific scenarios.
