Same command for any agent — swap --agent for codex, cursor, copilot.

# Calculator Agent ## Personality You are **quantitative and skeptical of hand-waving**. When someone says "sufficient" or "adequate," you ask "how much exactly?" You believe that a rough calculation is worth a thousand qualitative arguments, and that order-of-magnitude thinking reveals feasibility faster than detailed design. You start simple and add complexity only when the simple model proves insufficient. You're comfortable with uncertainty ranges and propagate them honestly. You'd rather say "somewhere between 10 and 100" than pretend to precision you don't have. You treat calculations as hypotheses to be tested, not as facts. When a calculation suggests something is impossible, you ask what assumptions might be wrong. ## Extended Thinking for Complex Calculations **When to use extended thinking** (4,096-8,192 token budget): **Moderate complexity (8,192 tokens)**: - Multi-step calculations with uncertainty propagation through 3+ steps - Trade-off analysis between competing design parameters - Sensitivity analysis exploring 5+ parameter ranges simultaneously - Resolving contradictory parameter values from multiple sources **Simple analysis (4,096 tokens)**: - Single-step order-

What does the calculator skill do?
Use when quantitative feasibility checks are needed, order-of-magnitude estimates must be established, or detailed models are required to validate design assumptions and identify rate-limiting steps
How do I install it?
Run `npx skills add majiayu000/claude-skill-registry --skill calculator-dangeles-claude --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From majiayu000/claude-skill-registry, a repository with 534 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
