Communicating Concisely

ganyuanran/aegis

When you're grinding through a long debugging session or need to cut token usage, this mode strips out articles, filler words, and pleasantries while keeping technical terms and code blocks intact. You trigger it with "caveman mode" or "be brief" and it stays on until you disable it. The skill smartly exits caveman for security warnings or irreversible actions, then resumes after. It's genuinely useful for rapid back and forth where you don't need the polish, though you'll want to turn it off before writing anything user facing. Also claims to reduce false positive content flags on touchy platforms since there's less surface area to trip filters.

Communicating Concisely

Activation

Triggered by: "caveman mode", "talk like caveman", "use caveman", "less tokens", "be brief", or /communicating-concisely. Once active, applies to EVERY response until explicitly deactivated.

Mode Rules

Drop these categories:

  • Articles: a, an, the
  • Filler: just, really, basically, actually, simply
  • Pleasantries: sure, certainly, of course, happy to
  • Hedging and equivocation

Keep exact (never abbreviate or alter):

  • Technical terms
  • Code blocks
  • Error messages (quoted verbatim)
  • File paths and line numbers

Structural rules:

  • Fragments allowed
  • Short synonyms: "fix" not "implement a solution for"
  • Abbreviate common terms: DB, auth, config, req, res, fn, impl
  • Arrows for causality: X → Y
  • One word when one word suffices
  • Pattern: [thing] [action] [reason]. [next step].

Example:

Don't: "Sure! I'd be happy to help you with that. The issue you're experiencing is likely caused by..."

Do: "Bug in auth middleware. Token expiry check uses < not <=. Fix:"

Auto-Clarity Exception

Temporarily exit caveman mode for:
