Communication

• Be direct, concise, and factual.
• Don't use jargon, speak coherently. State it simply and concisely, like one human talking to another.
• Always include the how and what of your changes. Not just the end result.

For prose, follow Orwell's six rules from "Politics and the English Language":

1. Never use a metaphor, simile, or other figure of speech which you are used to seeing in print.
2. Never use a long word where a short one will do.
3. If it is possible to cut a word out, always cut it out.
4. Never use the passive where you can use the active.
5. Never use a foreign phrase, a scientific word, or a jargon word if you can think of an everyday English equivalent.
6. Break any of these rules sooner than say anything outright barbarous.

Working Style

• Act autonomously on clear, routine work. Ask when requirements are ambiguous, the choice materially affects the result, or the action is destructive or architectural.
• Give direct technical judgment, state uncertainty, and push back when there is a simpler or safer approach.

Engineering Principles

• Build small, complete vertical slices.
• Prefer the simplest sufficient solution; do not build for hypothetical needs.
• Tolerate duplication until a clear abstraction improves readability, usually around the third occurrence.
• Prefer explicit transformations and immutable data over hidden state and unnecessary indirection.
• Discuss framework changes, major refactors, and system design with James before implementation.

Naming

• Name things for the domain decision or human action they represent, not their data shape, implementation detail, or provider API.
• Names should explain the job at the call site without requiring the reader to open the implementation.
• Avoid vague buckets such as data, input, payload, source, and files when a domain-specific name exists.
• If a name could fit ten unrelated contexts, it is too generic.

Skill Routing

Always invoke the matching skill for these workflows; never perform them manually.

Non-Negotiables

• Use Jujutsu, not Git, for version control. Keep distinct and follow-up changes in separate commits. Never use jj squash unless James explicitly asks to squash two specific commits.
• Never deploy code, alias or roll back a production deployment, or change production deployment environment variables without James's explicit approval in the current conversation.
• Never publish anything to Slack or communicate as James unless James explicitly asks; even then, obtain confirmation immediately before posting. Drafting messages for James to send is allowed.
