mess-benchmark

name	mess-benchmark
description	Benchmark the handover mess command on real-world open source projects. Use when the user wants to test mess transformations at scale, benchmark performance on large repos, or validate mess output quality. Triggers on "benchmark mess", "test mess on real projects", "run mess on fixtures", or similar requests.

Mess Benchmark

Run handover mess on large open-source fixture repos to benchmark transformations and validate output.

Fixture Repos

Located in fixtures/ as git submodules:

Language	Repo	Path	Glob Pattern
Rust	Next.js crates	fixtures/nextjs/crates	**/*.rs
JS/JSX/TS/TSX	Next.js	fixtures/nextjs/examples	**/*.{js,jsx,ts,tsx}
Go	Gin	fixtures/gin	**/*.go
Python	FastAPI	fixtures/fastapi	**/*.py
CSS	Next.js	fixtures/nextjs/examples	**/*.css
HTML	Bootstrap	fixtures/bootstrap	**/*.html

Benchmark Workflow

1. Reset fixtures to clean state:

git submodule foreach 'git checkout . && git clean -fd'

2. Run mess on target language:

# Rust
./handover mess fixtures/nextjs/crates --glob "**/*.rs" --recursive --all --intensity 0.5

# JavaScript/TypeScript
./handover mess fixtures/nextjs/examples --glob "**/*.{js,jsx,ts,tsx}" --recursive --all --intensity 0.5

# Go
./handover mess fixtures/gin --glob "**/*.go" --recursive --all --intensity 0.5

# Python
./handover mess fixtures/fastapi --glob "**/*.py" --recursive --all --intensity 0.5

# CSS
./handover mess fixtures/nextjs/examples --glob "**/*.css" --recursive --all --intensity 0.5

# HTML
./handover mess fixtures/bootstrap --glob "**/*.html" --recursive --all --intensity 0.5

3. Analyze changes:

# Summary stats
cd fixtures/<repo> && git diff --stat | tail -10

# View sample diff
cd fixtures/<repo> && git diff <file> | head -80

4. Report results with:
   • Files processed count
   • Insertions/deletions summary
   • Sample transformation examples
   • Any errors encountered
