Apply approved Xcode build optimization changes following best practices, then re-benchmark to verify improvement. Use when a developer has an approved optimization plan from xcode-build-orchestrator, wants to apply specific build fixes, needs help implementing build setting changes, script phase guards, source-level compilation fixes, or SPM restructuring that was recommended by an analysis skill.
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 Fixer Use this skill to implement approved build optimization changes and verify them with a benchmark. ## Core Rules - Only apply changes that have explicit developer approval. - Apply one logical fix at a time so changes are reviewable and reversible. - Re-benchmark after applying changes to verify improvement. - Report exactly what changed, which files were touched, and the measured delta. - If a change produces no improvement or causes a regression, flag it immediately. ## Inputs The fixer expects one of: - An approved optimization plan at `.build-benchmark/optimization-plan.md` with checked approval boxes. - An explicit developer instruction describing the fix to apply (e.g., "set `DEBUG_INFORMATION_FORMAT` to `dwarf` for Debug"). When working from an optimization plan, read the approval checklist and implement only the checked items. ## Fix Categories ### Build Settings Change `project.pbxproj` values to match the recommendations in [build-settings-best-practices.md](references/build-settings-best-practices.md). Typical fixes: - Set `DEBUG_INFORMATION_FORMAT = dwarf` for Debug - Set `SWIFT_COMPILATION_MODE = singlefile` for Debug …

How to install
mdr add patrickserrano/lacquer/xcode-build-fixer@sha256:c5c4b84274acec64The line at the top of this page pins the label git:20260827.52d6408, 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.
