claude-code - 💡(How to fix) Fix Stale officialMarketplaceAutoInstallFailReason causes permanent "Failed to install Anthropic marketplace" banner when marketplace is already installed

Summary

On every startup, Claude Code shows the orange notification "Failed to install Anthropic marketplace · Will retry on next startup" even though the official marketplace is installed and healthy (~/.claude/plugins/marketplaces/claude-plugins-official is a working sparse git checkout, fetches cleanly from origin, valid marketplace.json, listed in ~/.claude/plugins/known_marketplaces.json).

Repro

1. Hit a transient install failure once (e.g. brief git/network blip during a retry attempt) — this writes officialMarketplaceAutoInstallFailReason: "unknown" plus retry-count/timestamps into ~/.claude.json.
2. On a later startup, the marketplace successfully installs via the GCS-cached path.
3. From then on, the user-facing notification fires on every subsequent startup — until the user manually edits ~/.claude.json.

Root cause

The auto-installer (Ic_ in the bundled CLI) has two success branches.

The git-fallback success branch correctly clears the failure bookkeeping:

// git-fallback success — correct
a8(z => ({
  ...z,
  officialMarketplaceAutoInstallAttempted: true,
  officialMarketplaceAutoInstalled: true,
  officialMarketplaceAutoInstallFailReason: void 0,
  officialMarketplaceAutoInstallRetryCount: void 0,
  officialMarketplaceAutoInstallLastAttemptTime: void 0,
  officialMarketplaceAutoInstallNextRetryTime: void 0,
}));

The GCS success branch (taken when W28(K, $) returns non-null) only flips two fields and leaks the prior failure state:

// GCS success — leaks stale failure state
a8(Y => ({
  ...Y,
  officialMarketplaceAutoInstallAttempted: true,
  officialMarketplaceAutoInstalled: true,
}));

If a previous attempt set officialMarketplaceAutoInstallFailReason: "unknown" (plus a retry count and timestamps), those fields stay in ~/.claude.json forever. On startup, the gate gtA() short-circuits to false (because officialMarketplaceAutoInstalled === true), and Ic_ early-returns:

let q = H.officialMarketplaceAutoInstallFailReason ?? "already_attempted";
return { installed: false, skipped: true, reason: q };

Because of the ?? fallback, reason is the stale "unknown" instead of "already_attempted". The notifier then unconditionally renders:

} else if (H.skipped && H.reason === "unknown") {
  push({
    key: "marketplace-install-failed",
    text: "Failed to install Anthropic marketplace · Will retry on next startup",
    color: "warning",
    priority: "immediate",
    timeoutMs: 8000,
  });
}

Suggested fix

Either of these would resolve it:

• (preferred) Mirror the git-fallback success branch — clear FailReason / RetryCount / LastAttemptTime / NextRetryTime in the GCS success branch as well.
• (defensive) Have gtA() and Ic_'s early-return treat officialMarketplaceAutoInstalled === true as "already_installed" regardless of any leftover failure fields, so a stale FailReason can't leak into the notifier path.

Workaround

Manually delete these four fields from ~/.claude.json (leave Attempted and Installed alone):

• officialMarketplaceAutoInstallFailReason
• officialMarketplaceAutoInstallRetryCount
• officialMarketplaceAutoInstallLastAttemptTime
• officialMarketplaceAutoInstallNextRetryTime

After this, the banner stops appearing on next startup.

Environment

• Claude Code 2.1.143 (native installer)
• Windows 11 Enterprise
• Bedrock backend (CLAUDE_CODE_USE_BEDROCK=1)
• Marketplace folder is healthy: clean sparse git checkout of anthropics/claude-plugins-official, valid .claude-plugin/marketplace.json, listed in known_marketplaces.json with a recent lastUpdated.
