Included Skills3

artifact-creatorskills/artifact-creator/SKILL.md

Create or revise Agent Skills, host plugins and subagents, MCP servers and client configurations, hooks, and marketplace catalogs against their actual specifications. Use when building reusable agent capabilities or consolidating creator tooling without inventing a universal host format. Trigger with "create an agent skill", "build a plugin", "create an MCP server", "add a subagent", or "scaffold an agent integration".

artifact-validatorskills/artifact-validator/SKILL.md

Discover and validate Agent Skills, host plugins and subagents, MCP servers and configurations, hooks, and marketplace catalogs against the correct authority. Use when performing pre-merge review, external submission checks, portability audits, security checks, or validation of mixed agent-system repositories. Trigger with "validate this skill", "audit this plugin", "check this agent", "review this MCP config", or "is this marketplace ready".

production-upgradeskills/production-upgrade/SKILL.md

Upgrade an existing skill, plugin, agent, MCP integration, or agent-system package to a security-first production standard using pain research, architecture decisions, migration planning, deterministic implementation, adversarial tests, independent review, and revision-bound evidence. Use when modernizing a legacy capability or asking for Databricks-level diligence. Trigger with "production upgrade", "modernize this skill", "bring this pack to production quality", or "audit and rebuild this plugin".
