A3.7/5.0
Scored across 7 tools
Disambiguation5/5
Each tool targets a distinct stage or resource: family discovery, field schema, parametric search, part lookup, deterministic recommendation, substitution cross-reference, and spec distribution. search_parts' optional facet counts slightly overlap spec_distribution, but the aggregate-distribution versus top-N-search distinction is clear from the descriptions.
Naming Consistency4/5
All names use snake_case consistently, which makes the set readable. However, the pattern mixes verb_noun names such as list_families, search_parts, and recommend_parts with noun_phrase names such as part_details and spec_distribution, plus a bare verb cross_reference.
Tool Count5/5
Seven tools is well-scoped for a power electronics component catalogue and selection server. Each tool covers a distinct workflow step without obvious padding or redundancy.
Completeness4/5
The surface covers the main lifecycle: discover families, inspect schemas, search parametrically, view part details, recommend parts deterministically, find substitutes, and analyze spec distributions. Minor gaps such as batch/multi-part comparison or bulk BOM lookup are absent, but an agent can work around them with repeated calls.
Available Tools
7 toolscross_referenceCross-reference a partBRead-onlyIdempotentInspect
Find substitutes for a part by MPN — the deterministic, program-only cross-reference the Kelvin web app runs: pre-gate the catalogue at the ranker's own reject edges, then score every candidate on value, ratings, footprint and mount type. No LLM judgement. An original whose own specs are incomplete can never yield a clean 'recommended'.
Inputs: mpn (required), family (required), same_type, max_results, +2 more.
describe_familyDescribe a family's query vocabularyARead-onlyIdempotentInspect
The exact field names one family can be filtered, sorted and bucketed on, and the designRequirements keys its selector reads. Call this before search_parts on an unfamiliar family rather than guessing field names.
Inputs: family (required).
list_familiesList catalogue familiesARead-onlyIdempotentInspect
Every component family in the TAS catalogue, with how many parts it holds and whether it has a deterministic selector. Start here.
Inputs: no named parameters.
part_detailsLook up one partBRead-onlyIdempotentInspect
One part by MPN: its extracted specs and, optionally, the full TAS catalogue record behind them (datasheet URL, mechanical drawing, provenance).
Inputs: mpn (required), family (required), manufacturer, include_record.
recommend_partsRecommend parts for a requirementBRead-onlyIdempotentInspect
Kelvin's deterministic selector: rank real parts against a designRequirements block and return the candidates with the margins that ranked them. Same authority Kirchhoff and Heaviside select through — no LLM judgement, reproducible.
Inputs: family (required), requirements (required), options, max_results, +1 more.
search_partsSearch the parts catalogueARead-onlyIdempotentInspect
Parametric search over one family: numeric ranges, categorical values, MPN substring and manufacturer, with optional facet counts. This is the catalogue question — 'what parts do we have that ...' — and needs no converter design.
Inputs: family (required), sort, limit, offset, +2 more.
spec_distributionDistribution of a specARead-onlyIdempotentInspect
How one numeric spec is distributed across a filtered slice of a family — bucket counts (log or linear) plus how many parts state the value at all. Answers 'what is available' questions that a top-N list cannot.
Inputs: field (required), family (required), log, buckets, +1 more.
