build-perf-baseline SKILL.md skillA
build-perf-baseline from dotnet/skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add dotnet/skills/build-perf-baseline@git:20261016.6364668Pins git:20261016.6364668 in mdr.lock. Pin the fingerprint instead.

Establish MSBuild/.NET build performance baselines before optimizing. USE FOR: unranked slow builds; cold, warm, incremental or no-op measurements; before/after comparisons; CI output caching; static graph, artifacts output and dependency graph trimming. Start here before build-perf-diagnostics, incremental-build or build-parallelism. DO NOT USE FOR: known repeated-restore fixes (use eliminate-redundant-restores), non-MSBuild builds. For measured target/task/analyzer bottlenecks, use…
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
# Build Performance Baseline & Optimization ## Overview Before optimizing a build, you need a **baseline**. Without measurements, optimization is guesswork. This skill covers how to establish baselines and apply systematic optimization techniques. **Related skills:** - `build-perf-diagnostics` — binlog-based bottleneck identification - `incremental-build` — Inputs/Outputs and up-to-date checks - `build-parallelism` — parallel and graph build tuning - `eval-performance` — glob and import chain optimization --- ## Step 1: Establish a Performance Baseline Measure three scenarios to understand where time is spent. Keep the SDK, configuration, machine, environment variables, restore state, and build command consistent. Run each scenario at least three times, repeating its setup before every measured sample, and report the median plus the observed range; a single timing is not a baseline. Keep setup outside the timed interval. Save each sample's binlog under a unique name, outside generated output directories. ### Cold Build (First Build) No previous build output exists. Measures the full end-to-end time including restore, compilation, and all targets. …

How to install
mdr add dotnet/skills/build-perf-baseline@sha256:665fa0ae2f539367The line at the top of this page pins the label git:20261016.6364668, 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.
