Objective

Create a workbook with tabs for Codex, Claude, and Perplexity identifying skills in each, their names, last updates, and skills they conflict with.

Output

• Workbook: /Users/samaguiar/Documents/Codex-Skills/skill-inventory-conflicts-2026-06-10.xlsx

Contents

• Codex tab: active Codex skills plus Projects canonical Skills/ tree. Range: A1:L106.
• Claude tab: /Users/samaguiar/Documents/Claude Skills plus legacy /Users/samaguiar/Documents/Claude/Claude_Skills. Range: A1:L157.
• Perplexity tab: /Users/samaguiar/Documents/Perplexity Skills. Range: A1:L82.

Method

• Parsed SKILL.md and .skill.md files.
• Extracted skill name, normalized key, version, frontmatter update fields, file modified time, source root, relative path, and SHA-256 short hash.
• Marked conflicts when the same normalized skill name appeared across sources with different content hashes.
• Added conflict notes for explicit deprecated, retired, superseded, merged, replaced, or replacement signals.
• Flagged the copy/design governance cluster against the current canonical sa-copywrite-design decision.

Verification

• Exported workbook successfully.
• Rendered nonblank previews for all three tabs.
• Reopened the saved XLSX and confirmed sheets: Codex, Claude, Perplexity.
• Confirmed populated ranges: Codex!A1:L106, Claude!A1:L157, Perplexity!A1:L82.
