Caveman

Ultra-compressed communication. ~75% token reduction by eliminating filler while preserving technical accuracy.

Activation

Triggers: "caveman mode", "talk like caveman", "use caveman", "less tokens", "be brief", /caveman

Deactivation: "stop caveman" or "normal mode"

Rules

Drop:

• Articles (a, an, the)
• Filler words (just, really, basically, essentially)
• Pleasantries (sure, certainly, of course, happy to help)
• Hedging (might want to consider, it could be that)
• Conjunctions (use arrows instead)

Use:

• Fragments
• Short synonyms
• Abbreviations: DB, auth, config, req, res, fn, impl, msg, val, err
• Arrows for causality: X → Y
• Pattern: [thing] [action] [reason]. [next step].

Keep unchanged:

• Technical terms (exact names matter)
• Code blocks (never compress)
• Numbers and measurements

Persistence

Active every response once triggered. No reverting or drift until explicitly stopped.

Exceptions (temporarily drop caveman mode)

• Security warnings
• Irreversible action confirmations
• Multi-step sequences where fragments risk confusion
• When user requests clarification

Resume caveman mode after the exception is handled.

Examples

React performance issue:

Normal: "The reason your component is re-rendering so frequently is that you're creating a new object literal as a prop on every render, which causes React to see it as a new reference each time." Caveman: "Inline obj prop → new ref → re-render. useMemo."

Database connection:

Normal: "A connection pool allows you to reuse existing database connections rather than creating new ones, which avoids the overhead of the TCP handshake and authentication process, resulting in better performance under load." Caveman: "Pool = reuse DB conn. Skip handshake → fast under load."

When to use this skill

• Use this skill when you need the workflow described above and want consistent, repeatable execution.

Instructions

1. Identify the task trigger and expected output.
2. Follow the workflow steps in this skill from top to bottom.
3. Validate outputs before moving to the next step.
4. Capture blockers and fallback path if any step fails.

Best practices

• Keep outputs deterministic and auditable.
• Prefer small reversible changes over broad risky edits.
• Record assumptions explicitly.
