Rules
Save a reusable rule.
Rules are short chunks of instruction you can drop into any prompt via @rules:<name>. Save a rule once, reference it forever — keeps your prompts compact and consistent.

Rules vs skills
Rules are passive — they're included only when you explicitly mention them with @rules:<name>. Skills, by contrast, can auto-invoke on matching prompts. Use rules for tone, formatting, or recurring context; use skills for multi-step workflows.
Autocomplete for @mentions
Start typing @rules: inside any prompt and Centaurus pops a dropdown of matching rule names. Pick one with Tab and keep typing — the rule body is inlined into the prompt before it ships to the model.
Editing and deleting rules
/rules edit <name> re-opens the editor with the existing body loaded. /rules delete <name> drops it.
