Perfect for Code Optimization Agents needing advanced Ruby code analysis capabilities via RuboCop and Rust Triage is an experimental RuboCop rewrite in Rust, used to find and fix top cops by divergence in Ruby codebases.

How do I install triage?

Run the command: npx killer-skills add 6/nitrocop/triage. It works with Cursor, Windsurf, VS Code, Claude Code, and 15+ other IDEs.

What are the use cases for triage?

Key use cases include: Automating Ruby code optimization by identifying top cops to fix, Filtering cops by department using --department argument, Excluding complex layout cops using --exclude-department.

Which IDEs are compatible with triage?

This skill is compatible with Cursor, Windsurf, VS Code, Claude Code, GitHub Copilot, JetBrains, Cline, Roo Code, and many more. Use the Killer-Skills CLI for universal one-command installation.

Are there any limitations for triage?

Requires Python 3 to run triage.py script. Limited to Ruby developers using RuboCop. Needs gh run download for auto-downloading corpus-results.json.

Triage: Experimental RuboCop Rewrite Setup Guide

Run the triage script to find the top cops to fix:

bash
1python3 .claude/skills/triage/scripts/triage.py $ARGUMENTS

If no --input is provided, it auto-downloads the latest corpus-results.json from CI via gh run download.

Common invocations:

/triage — top 30 cops by divergence
/triage --limit 50 — show more
/triage --department RSpec — filter to one department
/triage --exclude-department Layout — skip complex layout cops
/triage --fp-only — only cops with false positives
/triage --input /tmp/corpus-report/corpus-results.json — use local file

After identifying targets, use investigate-cop.py to see all FP/FN locations with source context:

bash
1python3 scripts/investigate-cop.py Department/CopName --context --fp-only

Then read the cop source in src/cop/<dept>/<cop>.rs and the vendor spec at vendor/rubocop*/spec/ to understand the root cause before fixing.

This skill is read-only. Parallel-agent activity may leave unrelated local modifications in the working tree; do not edit or revert them while triaging. If triage transitions into code edits, switch to a dedicated git worktree before making changes, then use a fix skill workflow that integrates retained progress back into main before ending the run.
