Claude Skills Troubleshooting

Overview

Diagnose and resolve common Claude Code plugin and skill configuration issues. This skill provides systematic debugging workflows for plugin installation, enablement, and activation problems.

Quick Diagnosis

Run the diagnostic script to identify common issues:

python3 scripts/diagnose_plugins.py

The script checks:

Installed vs enabled plugins mismatch
Missing enabledPlugins entries in settings.json
Stale marketplace cache
Invalid plugin configurations

Common Issues

Issue 1: Plugin Installed But Not Showing in Available Skills

Symptoms:

```
/plugin
```
shows plugin as installed
Skill not appearing in Skill tool's available list
Plugin metadata exists in
```
installed_plugins.json
```

Root Cause: Known bug (GitHub #17832) - plugins are added to

installed_plugins.json

but NOT automatically added to

enabledPlugins

settings.json

Diagnosis:

# Check if plugin is in installed_plugins.json
cat ~/.claude/plugins/installed_plugins.json | grep "plugin-name"

# Check if plugin is enabled in settings.json
cat ~/.claude/settings.json | grep "plugin-name"

Solution:

# Option 1: Use CLI to enable
claude plugin enable plugin-name@marketplace-name

# Option 2: Manually edit settings.json
# Add to enabledPlugins section:
# "plugin-name@marketplace-name": true

Issue 2: Understanding Plugin State Architecture

Key files:

File	Purpose
`~/.claude/plugins/installed_plugins.json`	Registry of ALL plugins (installed + disabled)
`~/.claude/settings.json` → `enabledPlugins`	Controls which plugins are ACTIVE
`~/.claude/plugins/known_marketplaces.json`	Registered marketplace sources
`~/.claude/plugins/cache/`	Actual plugin files

A plugin is active ONLY when:

Exists in
```
installed_plugins.json
```
(registered)
Listed in
```
settings.json
```
→
```
enabledPlugins
```
with value
```
true
```

Issue 3: Marketplace Cache Stale

Symptoms:

GitHub has latest changes
Install finds plugin but gets old version
Newly added plugins not visible

Solution:

# Update marketplace cache
claude plugin marketplace update marketplace-name

# Or clear and re-fetch
rm -rf ~/.claude/plugins/cache/marketplace-name
claude plugin marketplace update marketplace-name

Issue 4: Plugin Not Found in Marketplace

Common causes (in order of likelihood):

Local changes not pushed to GitHub - Most common!

git status
git push
claude plugin marketplace update marketplace-name

marketplace.json configuration error

python3 -m json.tool .claude-plugin/marketplace.json

Skill directory missing

ls -la skill-name/SKILL.md

Diagnostic Commands Reference

Purpose	Command
List marketplaces	`claude plugin marketplace list`
Update marketplace	`claude plugin marketplace update {name}`
Install plugin	`claude plugin install {plugin}@{marketplace}`
Enable plugin	`claude plugin enable {plugin}@{marketplace}`
Disable plugin	`claude plugin disable {plugin}@{marketplace}`
Uninstall plugin	`claude plugin uninstall {plugin}@{marketplace}`
Check installed	`cat ~/.claude/plugins/installed_plugins.json \| jq '.plugins \| keys'`
Check enabled	`cat ~/.claude/settings.json \| jq '.enabledPlugins'`

Batch Enable Missing Plugins

To enable all installed but disabled plugins from a marketplace:

python3 scripts/enable_all_plugins.py marketplace-name

Skills vs Commands Architecture

Claude Code has two types of user-invocable extensions:

Skills (in
```
skills/
```
directory)
- Auto-activated based on description matching
- Loaded when user request matches skill description
Commands (in
```
commands/
```
directory)
- Explicitly invocable via
```
/command-name
```
- Appears in Skill tool's available list
- Requires command file (e.g.,
```
commands/seer.md
```
  )

If a skill should be explicitly invocable, add a corresponding command file.
