[BUG] Org plugin ("Installed by default") not reaching non-owner Member — Team plan

What's Wrong?

Similar symptom to the now-closed #58630, #56820, and #56844 — reopening as a fresh report since it's still occurring.

Setup

• Team plan org, private GitHub-synced marketplace (owner/repo pattern), plugin's User access = "Installed by default"
• Org admin console confirms marketplace status "Synced"

Symptom

• Org Owner account: plugin shows correctly, all skills listed, toggle ON
• Regular Member account: zero plugins shown in Settings → Plugins, in every project/folder tested (not just one)

Already ruled out

• Clicked Re-sync on the marketplace in admin console — no change
• Full app quit/relaunch on the Member's machine — no change
• Member confirmed GitHub org membership + Read access to the private repo
• Member connected her GitHub account via Claude's Connectors settings — no change
• Manually attempting "Add marketplace" with the repo URL fails with a generic "Failed to add marketplace" error, both before and after connecting GitHub
• Direct invocation of a skill by name in the correct project also fails to find it

Ask
Is this a known server-side sync/index issue (as suggested by resolution notes on related closed issues)? What's needed to force delivery to this member's account?

What Should Happen?

Expected: Member's Plugins page should show the org marketplace plugin as installed (matching what the Owner sees).

Actual: Zero plugins shown for the Member, on any project, through any of the above paths.

Error Messages/Logs

Failed to add marketplace.

That's the only error text shown anywhere in the UI — no additional detail, stack trace, or log output was surfaced on the "Add marketplace" dialog. No error appears at all on the Settings → Plugins page itself; it just silently shows zero plugins with no explanation.

Steps to Reproduce

• As org Owner, in the admin console (Settings → Plugins), add a private GitHub-synced marketplace (owner/repo format)
• Set the plugin's User access to "Installed by default"
• Confirm the marketplace shows status "Synced" in the admin console
• On a non-owner Member account, open the Claude Desktop app → Code tab, on any local folder
• Open Settings → Plugins for that project
• Observe: 0 plugins listed — not even the org plugin shown as installed-but-disabled
• From the admin console, click Re-sync on the marketplace — no change on the Member's side
• Fully quit and relaunch the Member's app, recheck Settings → Plugins — still 0 plugins
• Repeat step 5–6 in a brand-new, never-before-opened folder as the Code tab project — still 0 plugins
• On the Member's account, go to Settings → Plugins → Browse plugins → "+" (Add marketplace) → enter the same owner/repo URL → click Sync → observe Failed to add marketplace. error
• On the Member's account, go to Settings → Connectors → connect GitHub Integration (successfully authorizes) → repeat step 10 → same Failed to add marketplace. error
• In a chat in the Member's Code tab (correct project folder), directly ask Claude to run a specific skill from the plugin by name → Claude fails to find it in the plugin and falls back to an unrelated local file instead of the org-delivered skill

Additional Information

• Confirmed the plugin content itself is reachable — the org's GitHub App has repo access, and the Member's own GitHub account (connected via Claude Connectors) has confirmed Read access to the private marketplace repo. This rules out a permissions/credentials issue and points to something in the sync/delivery pipeline itself.
• The Owner account's Plugins page (Settings → Plugins → project scope) shows the plugin correctly: name, toggle ON, all skills listed by slash-command name, "Last updated" timestamp matching the latest push to the repo. Screenshot available on request but omitted here since it contains internal org/plugin names.
• Org admin console (Settings → Plugins) shows the marketplace row tagged "Synced" with a working Re-sync button — clicking Re-sync completes without error but produces no change on the affected Member's side.
• This is a Team plan org (not Enterprise), in case the underlying sync mechanism differs by plan tier.
• Related closed issues (#58630, #56820, #56844) describe the same category of symptom; one of those threads notes the eventual fix required an Anthropic engineer to manually reset the repo's index server-side — suggesting this may not be self-serviceable from the admin console at all.
