hyperfine-benchmarking skillA
hyperfine-benchmarking is agent-read markdown (skill) from akillness/jeo-skills: Use this skill to benchmark shell commands reliably with warmup runs, statistical summaries, and exportable artifacts using hyperfine..
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
# hyperfine-benchmarking
Benchmark CLI commands with reproducible methodology instead of one-off `time` output.
## When to use this skill
- Compare two or more command variants (`tool-a` vs `tool-b`)
- Validate performance impact before/after script changes
- Attach benchmark evidence to PRs
## Instructions
1. Confirm tool availability.
2. Keep input/workdir/environment stable across compared commands.
3. Run warmups and enough runs for stable variance.
4. Export JSON/markdown outputs for review.
5. Summarize relative speedup + risk notes.
## Examples
### Availability check
```bash
hyperfine --version
```
### Two-command comparison
```bash
hyperfine \
--warmup 3 \
--min-runs 10 \
'cmd_a --with flags' \
'cmd_b --with flags'
```
### Parameter sweep
```bash
hyperfine \
--warmup 3 \
--parameter-list mode fast,balanced,thorough \
'mytool --mode {mode} input.txt'
```
### Export artifacts
```bash
hyperfine \
--warmup 3 \
--min-runs 10 \
--export-json benchmark.json \
--export-markdown benchmark.md \
'cmd_a' 'cmd_b'
```
## Best practices
- Prefer relative speedup and confidence ranges over single-run claims.

How to install
mdr add akillness/jeo-skills/hyperfine-benchmarking@git:20260426.f097b4emdr add akillness/jeo-skills/hyperfine-benchmarking@sha256:5eb922a984425e55Pin 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.
