What's Wrong?

The Discord plugin (discord@claude-plugins-official) was previously installed and working (v0.0.4), but after updating Claude Code it fails to load with:

Status: ✘ failed to load
Error: Plugin discord not found in marketplace claude-plugins-official

Reinstallation also fails:

$ claude plugins install discord
✘ Failed to install plugin "discord": Plugin "discord" not found in any configured marketplace

$ claude plugins install discord@claude-plugins-official
✘ Failed to install plugin "discord@claude-plugins-official": Plugin "discord" not found in marketplace "claude-plugins-official"

The plugin's cached files still exist locally under ~/.claude/plugins/cache/claude-plugins-official/discord/0.0.4/, but the marketplace no longer resolves the plugin.

A similar issue was reported in #37638 (Windows 11, channels plugins not visible in marketplace) but was closed without resolution.

Expected Behavior

The Discord plugin should be discoverable in the marketplace and loadable as before.

How to Reproduce

1. Have Discord plugin previously installed (discord@claude-plugins-official v0.0.4)
2. Update Claude Code to 2.1.91
3. Run claude plugins list → Status shows "failed to load"
4. Run claude plugins install discord → "not found in any configured marketplace"

Claude Code Version

2.1.91

Platform

Windows 11 (10.0.26200)

Shell

Git Bash

Additional Context

• Related issue: #41768 (DISCORD_STATE_DIR not passed to plugin subprocess, regression from 2.1.88)
• The plugin was working on v2.1.88 and earlier
• Other plugins (playwright, memsearch) also show as disabled, suggesting a broader marketplace resolution issue
