Windows Local Domain, DOMPurify Checks, Prompt Automation, and Skill Design Training

Today was a mix of technical work and process cleanup to reduce manual overhead and improve consistency.

What I did

1. Edited the Windows hosts file to fake local domains

• Recalled the exact hosts workflow and mapped local domains for testing on the machine.
• Kept the shorthand note **config host local domain cho window** for quick reuse.

2. Worked with isomorphic-dompurify and expanded security checks

• Added and organized checks across URL, input variables, IP, and DNS.
• Goal: detect abnormal input early at the sanitize/validate layer.

3. Reduced the overhead of document generation

• Generating checklist, commit message, report, and trace was too repetitive.
• Wrote a single prompt that produces all of them in one run.

4. Training on skill design (basic -> detail design)

• Reinforced the path from basic structure to detailed specification.
• Focused on clarifying goals, constraints, and evaluation criteria in skill design.

Result

• Local domain mapping on Windows is stable and easy to reuse.
• isomorphic-dompurify checks are broader and more defense-in-depth.
• Prompt automation cuts down routine documentation work.
• Stronger mental model for skill design from basic to detail design.
