methodology-measure is agent-read markdown (skill) from feilipu/8085-skills: How to measure and prove z88dk library changes: z88dk-ticks TIMER/hotspots, map/nm proof, suite gates, A/B library swaps, math32 multi-CPU rebuilds, classic +test benchmarks, wiki number paste rules. Use when optimising, explaining deltas, or running +test -clib=8085 benches..
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
What the file says
# Methodology — measure, A/B, benches This skill covers **host tools** used with z88dk when writing or optimising 8085 (and portable 8080/gbz80) library code. Opcode and coding rules stay in **`cpu-8085`**; here the focus is *how to prove* what is slow, what changed, and what is correct — plus how **`z88dk-copt`** shapes compiler output and what library authors must do by hand. Assume a built z88dk tree with `bin/` on `PATH` and `ZCCCFG` pointing at `lib/config` (see env below). --- ## Environment (always set) ```bash export PATH=/path/to/z88dk/bin:$PATH export ZCCCFG=/path/to/z88dk/lib/config ``` Rebuild only what you touch (example: classic 8085 runtime object + crt0 lib): ```bash # after editing libsrc/l/sccz80/7-8085/... rm -f libsrc/classic/z80_crt0s/obj/8085/l/sccz80/7-8085/.../file.o rm -f libsrc/classic/z80_crt0s/obj/8085-crt0 make -C libsrc/classic/z80_crt0s obj/8085-crt0 # relink and install crt0 (cd libsrc && TYPE=8085 z88dk-z80asm -d -I"$ZCCCFG/.." -m8085 \ -DSTANDARDESCAPECHARS -x8085_crt0 @classic/8085.lst) cp -f libsrc/8085_crt0.lib lib/clibs/ ``` ### Math32 / multi-CPU float libs (force rebuild) …

How to install
mdr add feilipu/8085-skills/methodology-measure@git:20260920.88ac0a1mdr add feilipu/8085-skills/methodology-measure@sha256:3d28a27be934d380Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
