Review pull requests for decay risks and design smells

This skill runs a PR code review that surfaces decay risks, design smells, and maintainability issues, structuring every finding as Symptom, Source, Consequence, and Remedy, and drawing on twelve classic software-engineering books referenced in shared framework files - a common rules file defining an Iron Law and Health Score, a source-coverage file attributing findings to specific books, a decay-risks file defining symptom taxonomy, and this skill's own PR review guide. If the user hasn't specified files or pasted code, it applies its own automatic scope detection to determine what to review before proceeding.

Use it when asked to review code, check a PR, or when someone shares a diff or pastes code for review, expecting decay-risk and design-smell findings rather than a plain style check.

Given code, a diff, or an auto-detected scope, it scans for each decay risk in a specified order, runs a quick test check that's skipped for docs-only or non-production changes, applies the Iron Law to every finding, and outputs a report following the shared report template, labeled PR Review as its report mode.

Depends on companion reference files in a shared folder defining the review process, decay-risk order, and book attributions.

Developers and reviewers who want a structured, book-grounded PR review that names the specific engineering source behind each maintainability concern and prescribes a remedy, rather than a generic linting pass.
