Goal

Review and fix the changed code for quality, reuse, and efficiency. Operate entirely from the diff — do not read whole files or spawn agents.

Step 1 — Get the diff

Run:

git diff HEAD

If the diff is empty, check staged changes:

git diff --cached

Work only from this output. Do not read any source files beyond what the diff shows.

Step 2 — Review the diff inline

Scan the changed lines for these issues, in priority order:

Reuse

• New function that duplicates an existing one visible in the diff context
• Inline logic that a function already shown in the diff could handle
• Hardcoded constant that matches one already visible in the diff

Quality

• f'...' string with no {...} interpolation — remove the f prefix
• Comment that describes WHAT the code does (not WHY) — delete it
• Local constant defined inside a function that never changes — hoist to module level
• Stale data read from a snapshot that was taken before the relevant mutations

Efficiency

• Dict/object lookup inside a loop where the key never changes — move it outside
• Repeated computation of the same value within a tight loop
• Unnecessary intermediate variables used only once

Step 3 — Fix directly

Apply every fix you found by editing the file. Do not explain each fix — just make the change.

If a finding is a false positive, skip it silently.

Step 4 — Report

One-line summary per fix made. If nothing needed fixing, say "Code is clean."
