track-tariff-trends

Retrieve a country's average applied tariff over time — the MFN rate on all products, or the rate it applies on goods from one partner and/or in one product group — plus the optional US effective tariff rate. Use when the user asks how a country's tariffs have changed, or what it charges another country on average. For one product between two countries, use lookup-bilateral-tariff.

Quality

Content

96%Weight 40%Scale 1-5

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

An exemplary API skill body: lean, dense with non-obvious operational facts, fully executable examples covering both series, explicit error handling, and clear series-selection logic. The only structural nit is that the exhaustive WITS group list and response-field semantics could be split into a one-level-deep reference file.

DimensionReasoningScore

Conciseness

Every section carries non-obvious, API-specific facts (series-selection rules, NOT_COVERED semantics, entitlement gating, X-WorldMonitor-Key vs Bearer, "Data ends in 2023 for most reporters") with no padding and no explanation of concepts Claude already knows. Every token earns its place.

5 / 5

Actionability

Two fully executable curl examples with --data-urlencode and jq post-processing cover both series types (MFN and WITS weighted), plus a concrete endpoint URL, exact header format, and exact parameter values (840, 699, 000, 84-85_MachElec). Copy-paste ready.

5 / 5

Workflow Clarity

A single-action skill whose action is unambiguous: the one decision point (which series, chosen by partner/product-group) is explicitly specified, and the Errors section provides recovery loops (401 → missing key, 403 → entitlement tier, 429 → retry with backoff). Not a destructive or batch operation, so no validation cap applies.

5 / 5

Progressive Disclosure

Well-organized single file with clear section headers and all core call guidance appropriately placed. At ~107 lines with no bundle files, the exhaustive WITS group enumeration and response-field semantics are borderline reference material that could sit one level deep in a references/ file — a minor organization gap that keeps it below a 5.

Description

92%Weight 40%Scale 1-5

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

A strong description: concrete capabilities, an explicit use-when clause with natural trigger phrasing, and an explicit routing boundary to the bilateral-lookup sibling skill. The only minor gap is missing a few natural synonyms (e.g., "customs duties", "tariff trends").

DimensionReasoningScore

Specificity

The description enumerates multiple concrete capabilities — "the MFN rate on all products, or the rate it applies on goods from one partner and/or in one product group — plus the optional US effective tariff rate" — covering the skill's full parameter space. No gaps remain within the skill's scope.

5 / 5

Completeness

It explicitly answers both questions: the "what" ("Retrieve a country's average applied tariff over time…") and the "when" ("Use when the user asks how a country's tariffs have changed, or what it charges another country on average") with concrete trigger phrases.

5 / 5

Trigger Term Quality

Natural user phrasings are present ("how a country's tariffs have changed", "what it charges another country on average"), giving good keyword coverage. A few natural synonyms such as "customs duties", "duty rates", or "tariff trends" are missing, so it falls just short of comprehensive.

4 / 5

Distinctiveness Conflict Risk

The closing boundary clause "For one product between two countries, use lookup-bilateral-tariff" actively disambiguates the nearest sibling skill, and the niche (country-average tariff time series) has distinct triggers with minimal conflict risk.
