Plugin Dev

Validate plugin SKILL.md frontmatter and audit hook scripts for silent failures. Run validation to check all plugins pass schema, source path, and frontmatter checks. Run hook audit to detect unhandled errors in shell and Python scripts.

Plugin Development Tools

On-demand validation and hook auditing for the cc-skills marketplace.

Triggers

Use this skill when the user says: "validate plugins", "check plugin", "hook audit", "validate skills", "audit hooks", "check skill frontmatter", "plugin validation".

Available Tools

1. Plugin Validation

Validates all registered plugins: JSON Schema, source paths, orphan detection, and SKILL.md frontmatter.

bun scripts/validate-plugins.mjs

What it checks:

marketplace.json conforms to JSON Schema
All plugin source paths exist on disk
No orphaned plugin directories (dirs without marketplace entries)
SKILL.md frontmatter has valid name (kebab-case) and non-empty description
Every plugin has at least one component directory (skills/, hooks/, commands/, agents/)

2. Hook Audit

Scans hook and script files for silent failure patterns.

bash plugins/plugin-dev/scripts/audit-hooks.sh

What it checks:

Shell scripts (.sh): mkdir/cp/mv/rm without error handling (unless set -e is active)
Python scripts (.py): bare except: pass or except Exception: pass
Optional: ShellCheck integration (skipped with message if not installed)

Exit codes: 0 = clean, 1 = findings

Workflow

When the user asks to validate or audit:

Run bun scripts/validate-plugins.mjs for plugin validation
Run bash plugins/plugin-dev/scripts/audit-hooks.sh for hook auditing
Report results clearly — separate passing checks from failures
For failures, suggest specific fixes

Scaffolding

To scaffold a new plugin interactively, use the command:

/plugin-dev:create [plugin-name]

This is a separate slash command — not part of this skill.
