consistency-model-selector

consistency-model-selector is a skill for Claude Code from bookforge-ai/bookforge-skills. It costs 214 tokens per session (5,269 once invoked), scanned A, original, CC-BY-SA-4.0.

A guide for choosing how quickly changes become visible across a distributed system, including linearizable, causal, and eventual consistency. Distributed systems are applications whose data or services run across multiple machines.

In plain words
What is it for?
Use it when designing distributed data operations, deciding how reads should observe writes, or evaluating coordination mechanisms between services.
Why use it?
It helps balance correctness, availability, and coordination instead of applying one visibility rule everywhere. It also helps decide when a coordination service such as ZooKeeper or etcd is needed.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

consistency-model-selector scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 10d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
