What does the Lucian skill do?

Design a distributed system that stays correct under failure: pick the consistency model, handle partitions, and make it idempotent. Load it once into Claude Projects and you get a configured Distributed Systems Engineer without re-explaining context at the start of every session. Test changes in a branch or staging environment, run the tests, and verify against your own stack, versions, and load before shipping to production.

How do I install this skill file?

Download the .skill package (it contains SKILL.md), paste the contents into Claude Projects Instructions or your AI's system prompt, add your own context and start your first session. Works with Claude, ChatGPT, or any AI chat that accepts system prompts.

Which AI tools does this skill work with?

Works with Claude (recommended), ChatGPT, Gemini, Perplexity and Copilot, and any AI chat that accepts system prompts. Claude Projects gives the best results.

What is included in this download?

One .skill package delivered instantly after purchase: the full SKILL.md role configuration plus a worked-example file with a real scenario so you see the quality before you rely on it. No subscription, yours permanently.

How is this different from using Claude without the Lucian skill?

Without a skill file your AI starts every session as a general assistant. With Lucian loaded it applies Distributed Systems Engineer methodology from the first message, with consistent quality every time. Test changes in a branch or staging environment, run the tests, and verify against your own stack, versions, and load before shipping to production.

Consistency models: CAP, linearizability, eventual
Idempotency, exactly-once vs at-least-once, sagas
Event-driven design, Kafka, backpressure, failure modes

Teams building systems that span services or regions and must not lose or corrupt data under failure.A senior distributed systems engineer bills $140+/hr, this is one file, yours forever.

// what's inside

Drop Lucian into Claude and get a senior distributed systems engineer who reasons about consistency and failure before writing code, so your system stays correct when things go wrong.

Lucian designs correct distributed systems: consensus (Raft, Paxos), replication and sharding, consistency models (CAP, linearizability, eventual), idempotency and exactly-once vs at-least-once, distributed transactions and the saga pattern, event-driven architecture and message queues (Kafka), backpressure, and the failure modes that only show up under partition and partial failure. He starts from what must stay true when a node dies, not from the happy path.

What you get

→Consensus (Raft/Paxos), replication, sharding
→Consistency models: CAP, linearizability, eventual
→Idempotency, exactly-once vs at-least-once, sagas
→Event-driven design, Kafka, backpressure, failure modes

# Lucian - Distributed Systems Engineer

You are Lucian, a senior Distributed Systems Engineer. You reason about consistency and failure first, then write code.

## How you work
1. Define what must stay true under partition and partial failure
2. Choose the consistency model and delivery guarantee, and justify it
3. Make operations idempotent; design for retries and duplicates
4. Design the failure and recovery path, not just the happy path

Design for the failure case first. Never assume a network call succeeds or happens once.

Excerpt from the actual file you'll download.

// try it

prompt

$We are moving to microservices and worried about consistency across services. Help us design it correctly.

Lucian returns the consistency model choice with the reasoning, an idempotency and message-delivery strategy, a saga or outbox design for the cross-service transaction, the partition and failure behavior spelled out, and the specific correctness tests to run.
