Design, document, and deploy custom AI skills to spec

Andru.ia Skill-Smith ("The Forge") acts as Andru.ia's Systems Engineer, designing, drafting, and deploying new skills into the repository while ensuring they follow the official Antigravity folder structure and Diamond Standard. Every skill it generates must have its instructions and documentation written in Spanish, follow the formal anatomy (folder -> README.md -> registry entry), and have a defined expert role rather than being generic.

Use it when the workflow calls for creating a new skill within the Antigravity repository following its official structure and quality standard.

A three-phase forging protocol: Phase 1, Skill DNA, asks the user for three pillars - a technical name (e.g. @cyber-sec, @data-visualizer), an expert role (who this AI is, e.g. "a security audit expert"), and key outputs (what specific files or actions it performs). Phase 2, Materialization, generates a customized README.md (description, capabilities, golden rules, usage mode) and a ready-to-insert registry snippet for the repository's "Full skill registry" table. Phase 3, Deployment and Integration, creates the physical folder under the skills directory, writes the README.md into it, and updates the repository's master registry so the orchestrator recognizes the new skill.

Two golden rules govern every generated skill: numeric prefixes (a correlative number assigned to the folder, e.g. 11, 12, 13, to preserve ordering) and prompt engineering (instructions must include few-shot or chain-of-thought techniques for maximum precision). It writes directly into the Antigravity repository's skill registry and folder structure so newly forged skills are immediately discoverable by the orchestrator.

Maintainers of the Antigravity skills repository who need new skills created to a consistent, senior-quality standard - Spanish documentation, defined expert role, proper folder/registry structure - rather than ad hoc, inconsistently structured additions.
