What problem does it solve?
Standard code reviews often miss unnecessary complexity and over-engineering that accumulates in codebases, such as hand-rolled standard library functions, unneeded dependencies, and speculative abstractions that add maintenance burden without delivering user value.
Core Features & Use Cases
- Targeted Over-Engineering Detection: Scans code diffs for common bloat patterns including reinvented standard library functionality, unused dependencies, single-implementation abstractions, and dead flexible code.
- Structured Actionable Findings: Outputs one-line findings with file location, bloat type tag, what to cut, and the exact replacement, using standardized tags for consistency across reviews.
- Use Case: Use this Skill when reviewing a PR that adds a custom date formatting utility instead of using the platform's native Intl API, or imports a heavy validation library for a single simple check that the standard library can handle.
Quick Start
Use the ponytail-review skill to scan the latest pull request diff for over-engineering and get a prioritized list of code to cut with exact replacements.
