Test my skill222

~ . File visibility bug: buildSkillArchive (in bootstrap.go) only creates a tar.gz with SKILL.md! So Phabricator-bootstrapped skills only have SKILL.md visible. The StreamSkillContent function only fetches SKILL.md too. This is the core bug explaining why "only SKILL.md is visible".

1. Microsoft OAuth: Currently only static token-based auth stub. Need proper MS OAuth.

2. Owner model: OwnerTokenHash is a single hash, not multi-owner. Need SkillOwner junction table.

3. Missing delete endpoint: No way to remove skills via API.

So my plan is to tackle the database redesign first—adding a User table and SkillOwner junction table to support multiple owners. Then I'll implement Microsoft OAuth with proper Azure AD integration, fix the file visibility issue by making StreamSkillContent fetch the entire skill directory from Phabricator instead of just SKILL.md, and add the missing delete endpoint.

Looking at the actual implementation, the core problem is in bootstrap.go where StreamSkillContent only retrieves SKILL.md. I need to refactor it to use the directory-fetching logic from gitfetch.go so it pulls all files in the skill directory. Before diving into the code changes, I should clarify the scope with the user and understand their priorities—this is a substantial refactor that touches the database layer, authentication, file handling, and API structure. I'm seeing the core issues now: the Phabricator bootstrap only archives SKILL.md, so I need to either make StreamSkillContent fetch the full directory recursively or trigger a re-fetch when the editor opens. For the OAuth piece, I'll use Azure AD with MSAL, storing the user's OID and email. The owner model should shift from a token hash to a junction table or JSON array of user OIDs. For the delete endpoint, I need to clean up the Repository, Manifests, Tags, and any orphaned Blobs. Let me document all these changes in a plan. o
