Customize Capability modifies an already-installed workspace capability by adding or editing its MCP servers, skills, integrations, or agent guidance. Use it when a user wants to customize, change, or extend an existing capability, such as giving its agent new MCP tools.

Customize Capability is cataloged under AI Engineering on DirSkills. Customize Capability comes from a repository tagged agent, agent-harness, agent-os, agentic and ai.

README

Excerpt

Customize Capability

Modify a capability that is already installed in this workspace. The most common request is giving it an MCP server so its agent gains new tools, but the same flow covers adding skills, integrations, or guidance.

A capability's source of truth is its manifest at capabilities/<capability-id>/capability.yaml. Re-installing reads that manifest and upserts the capability — re-install IS the update mechanism, and it never creates a duplicate.

This is the opening of the README. Read the full README on GitHub.
