Coordinated omission in depth: response-coupled sampling, open/closed/semi-open workload models, scheduled-versus-actual clocks, generator saturation, correction at recording time versus at generation time, HdrHistogram's recordValueWithExpectedInterval semantics, what wrk2, k6, Gatling, JMeter and Locust each actually do, and the effect on capacity numbers. Use when a load test's p99 is far better than production's for the same endpoint, when a generator misses its planned schedule, when…

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

# Coordinated Omission

## Purpose

Establish whether a set of latency numbers is missing the samples that would have carried its
tail, and what to do about it. The failure this skill prevents is the SLO signed against a
load test whose p99 was structurally incapable of seeing the queue: the generator stopped
issuing requests exactly while the system was slow, so the worst moments produced one sample
instead of fifty.

The mechanism is precise: the measured system delays or suppresses future observations that the
target arrival process would have generated. The resulting sample is conditioned on the system
being responsive. A 500 ms completed request may still be recorded as 500 ms, while scheduled
arrivals during it are absent, delayed, or timed from their eventual send rather than their due
time. The distortion can therefore affect sample density, offered load, queue state and the clock
used for each value. Counts are necessary evidence, but they do not identify the cause alone.

## Workflow

Start with the claim being assessed and reuse matching schedules, traces, counters and tool
configuration. A question about an already-valid closed experiment may need only a scoped
…

How to install

The exact contents, by fingerprint
mdr add robsonkades/agent-skills/coordinated-omission@sha256:de5b161d1501bfec

The line at the top of this page pins the label git:20261016.c769bd8, 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.
