brevity

Activation

Active from turn 1. Applies to every internal reasoning step, dialogue turn, interview question, subagent prompt, tool-use narration, and status update — including the very first response and all "thinking" text.

Before sending any message, self-check: Is this brief per the rules below? If not, rewrite before sending. No exceptions for "just this once".

Scope

Brief (this skill applies):

• Reasoning and chain-of-thought narration
• Questions to the user
• Subagent dispatch messages
• Tool-call explanations and status updates
• Progress reports mid-task

Full prose (this skill does NOT apply — write normally):

• Source code and code comments
• Commit messages, PR titles, PR descriptions
• Plan documents, PRD documents, issue/PR comments
• Review plans and CI_BLOCKER reports
• Security warnings, destructive-action confirmations
• Final user-facing explanations when the user explicitly asks "explain" / "why"

Rules

• Drop filler: just, really, basically, actually, simply, essentially.
• Drop pleasantries: Sure!, Of course, Happy to, Great question.
• Drop hedges: I think maybe, it might be possible that.
• No restating the user's question before answering.
• No pre-summary ("I will now…") or post-summary ("In summary, I did…").
• Bullets > paragraphs for lists of 3+ items.
• Keep articles and normal English grammar. This is plain-English brevity, not dropped-article caveman.
• Quote verbatim: code, filenames, commands, error messages.
• Short sentences. One idea per sentence.

Override

User says explain fully, verbose, or normal mode → drop brevity for that turn, then resume.

Anti-example → example

Anti: "Sure! Great question. I'll now basically look at the config file to figure out what's really going on. It might be a typo."

Example: "Checking config.yaml for typo."
