Decide what is worth making faster in this repo, and prove it paid — measure the thing instead of grepping for it, separate wall clock from total CPU from the critical path, rank targets by shape rather than by how many modules import them, and decline the work with a number when the number says so. Use this whenever someone asks to speed up the tests, the sweep, the gates, CI or a hook; when a profile or a grep suggests a hot spot; when a refactor is justified by "this file is bad" rather…
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
# Choosing what to optimize Everything here was paid for. The figures are from one pass over this repo's own test machinery, and every one of them carries the command that re-derives it, because a number in a document is a number that rots. The short version: **the repo has no cheap 20% lying around.** What it has is a handful of suites doing real work against real git and real browsers. So the value of an optimization pass here is mostly in *not* doing the wrong one. ## Measure the thing; do not grep for it Three findings in one session were reported wrong, each because a grep stood in for a run: | claimed | actual | why the grep lied | |---|---|---| | 38 `subprocess` calls in a suite | **453** child processes | the grep counted textual occurrences; most calls span lines and most spawns come from the code under test | | 1 tool without a test suite | **3** | all three printed a *pointer* containing `--selftest`, so the grep matched the word and missed the absence | | 0 section markers in an 8000-line file | **42** | the lint's own regex allows two spaces of indentation; the grep was anchored at column 0 | …

How to install
mdr add aleksandarbisevac/claude-plugins/choosing-what-to-optimize@sha256:36572daec2bac9e5The line at the top of this page pins the label git:20260822.a99edbd, 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.
