eval-performance SKILL.md skillA
eval-performance 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/eval-performance@git:20260930.ac46442Pins git:20260930.ac46442 in mdr.lock. Pin the fingerprint instead.

Guide for diagnosing and improving MSBuild project evaluation performance. USE FOR: builds slow before any compilation starts, high evaluation time in binlog analysis, expensive glob patterns walking large directories (node_modules, .git, bin/obj), deep import chains (>20 levels), preprocessed output >10K lines indicating heavy evaluation, property functions with file I/O ($([System.IO.File]::ReadAllText(...))), multiple evaluations per project. Covers the 5 MSBuild evaluation phases, glob…
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
# Diagnosing MSBuild Evaluation Performance Evaluation is the work MSBuild does *before* any target runs — reading project files, processing imports, expanding globs. This skill helps you **find and confirm** evaluation bottlenecks. Measure first; recommend a change only when a measurement proves it is warranted. ## Confirm the problem before changing anything Engage only when evaluation is *measurably* the bottleneck. Do NOT act when: - **The slowness is during compilation or target execution, not evaluation.** That is not an evaluation problem — use `build-perf-diagnostics` instead. - **The complaint is "rebuilds too much" / incremental build.** Use `incremental-build` instead. - **You have no measurement.** If no binlog or timing summary shows evaluation is slow, gather one first (see below). Do not guess from reading project files. - **A pattern below appears but evaluation is already fast.** Broad globs, deep imports, or `EnableDefaultItems` are only worth flagging when the numbers show they cost real time. A project that evaluates quickly needs no change. When a pattern is present but unmeasured, **report it as an observation and let …

How to install
mdr add dotnet/skills/eval-performance@sha256:b69eed236895f50bThe line at the top of this page pins the label git:20260930.ac46442, 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.
