deliverability-ops

I found your skill while evaluating the grading framework—the deliverability-ops approach caught my attention because it treats email infrastructure as a first-class engineering problem rather than just configuration management. That said, the C-grade (74/100) suggests there's real opportunity to tighten up the architecture and documentation.

The TL;DR

You're at 74/100, C-grade territory—based on Anthropic's best practices for agentic skills. Your strongest area is Spec Compliance (12/15), which means the metadata and frontmatter are clean. The weakest areas are Utility (12/20) and Progressive Disclosure (22/30)—you've got the right structure, but you're missing the hands-on templates and examples that make skills actually usable.

What's Working Well

• Clean metadata structure – Your YAML frontmatter is valid, and the skill name follows hyphen-case conventions properly
• Consistent terminology – ISP, IP warmup, authentication signals stay consistent throughout
• Focused scope – The skill doesn't try to be everything; it targets a specific problem (diagnosing and fixing email deliverability)
• Professional tone – No marketing fluff, just instructional content

The Big One: Missing Template Files

This is your single biggest blocker. You mention three templates in lines 29-32:

• Deliverability diagnostic worksheet
• IP/domain warmup tracker
• Compliance checklist

But they don't exist as actual files. Users need to create these from scratch, which defeats the purpose of having a skill.

The fix: Create three reference files in a references/templates/ directory:

1. deliverability-diagnostic.md – A fill-in-the-blank diagnostic with fields for ISP breakdo...
