The TL;DR

You're at 88/100, solid B-grade territory. This is based on Anthropic's skill best practices rubric. Your strongest area is Ease of Use (24/25) – the workflow and navigation are really clean. The biggest drag is unvalidated legacy content that's tanking your Utility score (16/20) and creating uncertainty about what actually works.

What's Working Well

• Progressive Disclosure nailed it – Your modular structure with _toc.md and layered modules is exactly how PDA should work. Clear hierarchy without burying users in detail upfront.
• Workflow clarity is chef's kiss – The research checklist with numbered steps and validation checkpoints in modules/research-checklist.md is how you actually help users avoid bad info.
• Metadata and discoverability – Name follows conventions, trigger terms are explicit in the core-guidance module, terminology stays consistent across files.

The Big One: Unvalidated Legacy Content

This is your main bottleneck. Your skill is marked with:

⚠️ Legacy template awaiting research upgrade

This creates a trust problem. Users can't tell which sections have been validated and which haven't. You're leaving 5+ points on the table here.

The fix: Complete the research checklist you've already built. Go through each module (grammar, conversation, dialects, etc.), validate the examples against current Spanish standards, and mark confidence levels. Update the status from "low confidence" to "medium" or "high" with specific notes on what's been validated. This isn't about rewriting – it's about auditing what you have.
