Choosing distributed consistency guarantees as an engineering decision: linearizability, sequential/causal ordering, session guarantees (read-your-writes, monotonic reads), bounded staleness and eventual convergence, stated as observable contracts rather than a false total ladder; CAP stated correctly—the choice between C and A exists only while partitioned—and PACELC, replica paths and transaction isolation boundaries. Use when a user cannot see their own write, when a read after a write…
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
# Consistency Models ## Purpose Specify the weakest set of guarantees that satisfies observable requirements and price it. The models are not one total ladder: recency, ordering, session, convergence and multi-object atomicity are different dimensions. Stronger coordination often costs latency or partition availability, but the cost depends on topology, implementation and workload. The failure this prevents is the requirement expressed as a model name. "We need strong consistency" cannot be verified, priced, or tested. "A user must never see their own comment disappear after posting it because a replica has not applied the write" names an observation. Eventual convergence alone is insufficient; it can coexist with read-your-writes for that session. No global linearizability requirement follows from this observation alone. ## Workflow 1. **State the requirement as something a client observes.** "Two users must never both be assigned seat 14C." "A user must never see their own write disappear." "A balance may lag by up to five seconds but reads must not regress to an older committed revision." A legitimate …

How to install
mdr add robsonkades/agent-skills/consistency-models@sha256:e932e26e7f4b8e0aThe 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.
