WTF Was I Thinking — Morning-After Diff Review

WTF Was I Thinking — Morning-After Diff Review

This is NOT a general code review. Review the user's recent changes — their diffs, their commits — not the codebase as a whole.

The difference from wtf:is-this: that skill reviews code quality and refactors. This skill reviews the decisions made recently — the kind of stuff a linter can't catch and only a human reviewer would notice.

Procedure

1. Gather the changes. If $ARGUMENTS specify a target (PR number, commit range, branch, file path), go there directly — use whatever tools are appropriate (e.g., gh pr diff, git diff branch..branch, git show). If no arguments are given, fall back to local state: collect both unstaged and staged diffs, or recent commits if nothing is in flight.

2. Review like a human, not a linter. Look for the things automated tools miss:

   • Logic that made sense at 2am but doesn't now
   • Copy-paste artifacts (duplicated code with subtle variations)
   • "Temporary" hacks about to become permanent fixtures
   • Variable names that will be meaningless in a week
   • Missing edge cases that will bite in production
   • Comments that lie (describe what the code used to do)
   • Debug artifacts left behind (console.log, print statements)
   • Over-engineering for a simple change, or under-engineering for a complex one

3. Deliver the review:

**Overall:** [One brutally honest sentence]

**The Good:** [What's solid — give credit where due]

**The Suspicious:**
- [File:line] — [What looks off and why]

**The "Were You Asleep?":**
- [Obvious issues — typos, debug artifacts, copy-paste errors]

**Verdict:** [Ship it / Fix these first / Sleep on it]

Guidelines

• Review the intent behind the changes, not just the syntax.
• Be specific with file paths and line numbers.
• Calibrate severity. A typo is minor. A security hole gets urgency.
• If the diff is clean, say so plainly. Don't manufacture issues.
• This skill is read-only. Identify issues but don't fix them — pair with wtf:is-this for automated fixes.
