Managed config skills were delivered two ways at once on launch: registered into the skills MCP connection AND downloaded to disk, so every managed skill double-listed (once as an MCP tool, once as a local /skills file). Deliver them by download only and remove the MCP path. Delete apply_managed_skills and drop the launch-time MCP registration for managed skills; the managed download path is unchanged. The managed_skill_locations state field it maintained is now unused; leave any existing values in place since nothing reads them. Co-authored-by: Isaac <no-reply@databricks.com>

What
Managed-config skills are now delivered to agents by download only. This removes the managed→skills-MCP registration path (
apply_managed_skillsand themanaged_skill_locationsstate tracker), keeping the download path (_download_managed_skills/download_managed_skills_on_launch) and the managed-config authoring side (setup skills,skills.names) unchanged.Why
The launch path delivered managed skills two ways at once: registered into the skills MCP connection and downloaded to disk. Download and MCP are an either/or choice, so this double-listed every managed skill — once as a local
/skillsfile and once as an MCP tool with the same description, which confuses the agent.Removing the MCP path directly should be safe: since no workspace should be using managed skills yet.
Notes
This is the base of the per-agent skills-scope stack. With managed skills out of the skills MCP connection, that connection holds only a developer's own
skill add --mcpschemas, so the per-agent work above no longer has to union in or track a global managed set.This pull request and its description were written by Isaac.
