Each tool targets a fundamentally different decision shape: gate = command allow/deny/ask, classify = pick one known label, route = pick one tool from a fixed candidate list, score = numeric 2–10 rating. The descriptions explicitly state when NOT to use each tool and cross-reference the alternatives (e.g. 'use route instead of classify when labels are unknown'; 'use score to rate each candidate'), which eliminates the usual classify/route/score overlap.

All four names are single lowercase English words with no camelCase/snake_case mixing, which is highly predictable. The only minor deviation is that gate reads as a noun/resource while classify, route, and score are verbs, but the concise one-word convention is still uniform.

Four tools is well within the ideal 3–15 range and each corresponds to a distinct decision primitive (permit, categorize, select, rate). Nothing feels padded or missing at the count level; the surface is tightly scoped to a decision/judgment layer.

The server covers the core judgment operations—ternary gating, closed-set classification, single-choice routing, and bounded scoring—with explicit fail-closed/error behavior, so no major workflow dead-ends. Minor gaps exist around batch/multi-item evaluation and combined multi-step decisions, but agents can chain the four tools to work around these.
