xcode-build-benchmark SKILL.md skillA

xcode-build-benchmark from patrickserrano/lacquer is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned
mdr add patrickserrano/lacquer/xcode-build-benchmark@git:20260713.4950395

Pins git:20260713.4950395 in mdr.lock. Pin the fingerprint instead.

Benchmark Xcode clean and incremental builds with repeatable inputs, timing summaries, and timestamped `.build-benchmark/` artifacts. Use when a developer wants a baseline, wants to compare before and after changes, asks to measure build performance, mentions build times, build duration, how long builds take, or wants to know if builds got faster or slower.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Xcode Build Benchmark

Use this skill to produce a repeatable Xcode build baseline before anyone tries to optimize build times.

## Core Rules

- Measure before recommending changes.
- Capture clean and incremental builds separately.
- Keep the command, destination, configuration, scheme, and warm-up rules consistent across runs.
- Write a timestamped JSON artifact to `.build-benchmark/`.
- Do not change project files as part of benchmarking.

## Inputs To Collect

Confirm or infer:

- workspace or project path
- scheme
- configuration
- destination
- whether the user wants simulator or device numbers
- whether a custom `DerivedData` path is needed

If the project has both clean-build and incremental-build pain, benchmark both. That is the default.

## Worktree Considerations

When benchmarking inside a git worktree, SPM packages with `exclude:` paths that reference gitignored directories (e.g., `__Snapshots__`) will cause `xcodebuild -resolvePackageDependencies` to crash. Create those missing directories before running any builds.

## Default Workflow

1. Normalize the build command and note every flag that affects caching or module reuse.

How to install

The exact contents, by fingerprint
mdr add patrickserrano/lacquer/xcode-build-benchmark@sha256:7056726f9bb0cce7

The line at the top of this page pins the label git:20260713.4950395, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
