Deep code review and quality analysis for vm0 project
53 charsno explicit “when” trigger
Intermediate

Key capabilities

  • →Review pull requests by ID
  • →Analyze commit ranges or single hashes
  • →Generate automated review reports in markdown
  • →Cleanup defensive try-catch code patterns
  • →Cross-reference changes against bad-smell documentation

How it works

Parses the input scope, populates a structured folder, and iterates through commits comparing code changes against a predefined bad-smell markdown file.

Inputs & outputs

You give it
PR ID, commit hash, or range string
You get back
Markdown reports in codereviews/YYYYMMDD/

When to use code-quality

  • →Review pending pull requests for vm0
  • →Analyze quality of recent commits
  • →Clean up unnecessary defensive code
  • →Generate code review reports for project history

About this skill

Code Quality

Operations

  • review <pr-id|commit-range|description>: review the identified change. For a PR, follow REVIEW.md; it owns practice routing, evidence, verdicts, and posting. For a commit range, apply the same relevant practices and report findings to the caller without inventing a PR destination.
  • cleanup [scope]: implement removal of redundant error handling in the requested scope. The existing defensive-code-cleanup command routes here.

Read code quality and select additional guidance from the documentation index. Searches identify candidates; inspect actual behavior before reporting a violation.

Error-Handling Cleanup

Search the requested source for catches that only log and rethrow, fabricate a generic success/empty result, or duplicate a framework-owned error response. For an unbounded cleanup request, select up to ten related, justified removals.

Before removing each catch, trace its caller and owning error boundary. Establish what the caller observes after removal and why the existing handler is redundant. Do not remove:

  • meaningful rollback, resource cleanup, retry, or recovery;
  • domain-error conversion to a contractual HTTP response;
  • explicitly owned best-effort operations or per-item failure isolation;
  • authentication, permission, or other fail-closed security handling;
  • required cross-version behavior or expected external-reference misses.

Apply fallback rules, deployment compatibility, and reference authority when those boundaries are involved. A catch containing only a log is not automatically redundant: verify whether it owns necessary diagnostics or rejection handling.

Remove unused imports and adjust callers only when the preserved contract requires it. Keep async work attached to its owning cancellation signal; detach() is not a replacement for error handling inside signals.

Completion

Show each finding or removal with its file, behavior, and evidence. Do not assign severity from a regex match or file length alone. Run checks for the changed scope and relevant consumers under project verification. Report remaining uncertainty explicitly. Create a PR when the caller requested one; a research or review request alone does not authorize implementation.

When not to use it

  • →Projects unrelated to the vm0 codebase
  • →When only simple linting is required

Limitations

  • →Depends on local docs/bad-smell.md file
  • →Strict directory structure requirement
  • →Requires git history access

How it compares

It enforces project-specific architectural standards and documentation-based quality checks rather than general-purpose style rules.
