📄 Description

The /create (L155-193) and /id/{id}/update (L248-297) endpoints in routers/skills.py persisted form_data.access_grants directly to AccessGrants.set_access_grants without filter_allowed_access_grants, while every other shareable resource in the codebase (channels, knowledge, models, notes, prompts, tools, calendars) and the dedicated /id/{id}/access/update endpoint on this same router (L309-348) all do call the filter. A user with workspace.skills permission (default False, but admins can grant it to skill-creating users) could therefore attach {"principal_type":"user","principal_id":"*","permission":"read"|"write"} to the create or update payload and have it persisted unfiltered, bypassing the sharing.public_skills gate that the rest of the cohort enforces.

Two changes:

create_new_skill: call filter_allowed_access_grants with 'sharing.public_skills' immediately before insert, after the existing permission check and ID-taken check.
update_skill_by_id: call filter_allowed_access_grants with the same key after the access check, before form_data.model_dump() flows into Skills.update_skill_by_id. The pre-existing access check at L263-277 only restricts WHO may modify the skill; the new filter restricts WHICH grants they may set.

All supporting plumbing was already in place from prior PRs: filter_allowed_access_grants is already imported at L22, the USER_PERMISSIONS_WORKSPACE_SKILLS_ALLOW_PUBLIC_SHARING constant exists, DEFAULT_USER_PERMISSIONS['sharing']['public_skills'] is wired up, SharingPermissions.public_skills is in the Pydantic, and the admin UI already renders the toggle. This is a pure 2-line router fix that closes the cohort-consistency gap.
