Conciseness

The body is lean — pricing is a compact table, levers are one-line bullets, and a small code skeleton replaces prose — and it avoids explaining concepts Claude already knows. Could not justify a 2 as there is no padded or unnecessary explanation.

Actionability

Provides an executable TypeScript routing skeleton plus concrete per-lever guidance (cap max_tokens, temperature:0 caching, batch 10-in-1), with complete copy-paste code clearly signaled in references/implementation.md.

Workflow Clarity

Six levers are explicitly ordered ('Apply these six levers in order. Each compounds on the last') with a usage-tracking feedback loop that catches spend regressions and an error-handling table for recovery; the destructive/batch cap does not apply because verification is present.

Progressive Disclosure

SKILL.md is an overview with two well-signaled, one-level-deep references (implementation.md, examples.md) — both real files listed in the Resources section — matching the top anchor for clear navigation.

Specificity

Names multiple concrete actions — 'model routing, token management, and usage monitoring' — matching the anchor that lists several specific actions rather than vague language.

Completeness

Clearly answers both what ('Optimize Groq costs through model routing...') and when via an explicit 'Use when...' clause plus trigger phrases, satisfying the top anchor.

Trigger Term Quality

Explicit trigger phrases ('groq cost', 'groq billing', 'reduce groq costs', 'groq pricing', 'groq expensive', 'groq budget') are natural terms a user would say, giving good coverage.

Distinctiveness Conflict Risk

All triggers are Groq-specific and the niche (Groq cost optimization) is distinct, making conflict with other skills unlikely.
