Claude-skill-registry check-skill-conflicts

This skill should be used when checking for naming conflicts between local skills (~/.claude/skills) and plugin-provided skills (~/.claude/plugins). Use to identify duplicate or similarly named skills that may cause inconsistent agent behavior.

Check Skill Conflicts

Identifies naming conflicts between local Claude Code skills and plugin-provided skills.

Why This Matters

When a skill exists in both

~/.claude/skills/

(local) and

~/.claude/plugins/

(plugin), agents may:

Load the wrong skill version
Get inconsistent results between sessions
Have unpredictable behavior when skill names are similar

Quick Check

# Run conflict check
~/.claude/plugins/marketplaces/plinde-plugins/check-skill-conflicts/skills/check-skill-conflicts/scripts/check-conflicts.sh

# Verbose output (shows all skills found)
~/.claude/plugins/marketplaces/plinde-plugins/check-skill-conflicts/skills/check-skill-conflicts/scripts/check-conflicts.sh --verbose

# JSON output for programmatic use
~/.claude/plugins/marketplaces/plinde-plugins/check-skill-conflicts/skills/check-skill-conflicts/scripts/check-conflicts.sh --json

What It Checks

Exact Matches - Same skill name in both locations
Similar Names - Names that differ only by suffix/prefix (e.g.,
```
foo
```
vs
```
foo-skill
```
)
Case Variations - Same name with different casing

Output Example

SKILL CONFLICT CHECK
====================

Local Skills:     45 found in ~/.claude/skills/
Plugin Skills:    12 found in ~/.claude/plugins/

EXACT MATCHES (High Priority):
  ⚠️  kyverno-version-lookup
      Local:  ~/.claude/skills/kyverno-version-lookup/
      Plugin: ~/.claude/plugins/marketplaces/plinde-plugins/kyverno-version-lookup/

SIMILAR NAMES (Review Recommended):
  ⚡ plugin-creator ~ plugin-dev
      Local:  ~/.claude/skills/plugin-creator/
      Plugin: ~/.claude/plugins/marketplaces/.../plugin-dev/

No conflicts: ✅ (if none found)

Resolution Options

When conflicts are found:

Remove local skill - If plugin version is preferred

cd ~/.claude/skills && git rm -r <skill-name>

Uninstall plugin - If local version is preferred

/plugin uninstall <plugin-name>

Rename local skill - If both are needed but different

mv ~/.claude/skills/<old-name> ~/.claude/skills/<new-name>
# Update SKILL.md frontmatter name field

Skill Locations

Type	Path Pattern
Local Skills	`~/.claude/skills/<name>/SKILL.md`
Plugin Skills	`~/.claude/plugins/marketplaces/*/<plugin>/skills/<name>/SKILL.md`
Symlinked Plugins	`~/.claude/plugins/<symlink>/*/skills/<name>/SKILL.md`

Self-Test

# Verify script exists and is executable
test -x ~/.claude/plugins/marketplaces/plinde-plugins/check-skill-conflicts/skills/check-skill-conflicts/scripts/check-conflicts.sh && \
  echo "✅ check-conflicts.sh exists" || echo "❌ Script missing"

# Run a quick check
~/.claude/plugins/marketplaces/plinde-plugins/check-skill-conflicts/skills/check-skill-conflicts/scripts/check-conflicts.sh --json | jq -e '.local_count >= 0' > /dev/null && \
  echo "✅ Script runs successfully" || echo "❌ Script failed"
