explain_dutch_vehicle_term

Read-onlyIdempotent

Read one existing Dutch vehicle definition by lowercase term slug or term.. Use search_vehicle_knowledge for free text or an unknown key, get_answer_context for a known answerId, or get_model_context for model-specific context. No fuzzy definition generation. Unknown valid key returns TERM_NOT_FOUND; uppercase/spaced inputs fail validation before normalization. Public read-only access; no knowledge writes. Calls consume rate limits.

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
termKeyYesExisting lowercase term slug or the same slug prefixed with term., e.g. apk or term.apk. 1–200 characters; ASCII letters/digits with single hyphen separators. No spaces, uppercase or fuzzy matching; these fail schema validation before normalization.

Output Schema

TableJSON Schema
NameRequiredDescriptionDefault
dataYesTool-specific successful result. Search returns an array (possibly empty); exact tools return the requested record or projection. Tool errors use a separate isError envelope.
sourcesYesResolved public SOURCE/SOURCE_GROUP records supporting this result. Search may leave this empty; use get_source_context for a discovered source ID.
coverageNoAvailable coverage metadata; incomplete or absent coverage is not an assurance of complete knowledge. Preserve limitations.
evidenceYesExposed evidence references with classifications and source IDs. May be empty (including search); not proof that knowledge has no provenance.
freshnessYesAvailable freshness metadata. Distinguish dataAsOf, sourceCheckedAt, editorialReviewedAt and generatedAt; missing fields do not mean current.
citationUrlNoHuman-readable KentekenKompas citation URL for this record/context; distinct from an original sourceUrl and a kk:// resource identity.
limitationsYesExplicit scope and interpretation limits to preserve in client answers. Empty does not certify complete coverage.
schemaVersionYesTransport envelope contract kk-api-v1; distinct from the nested knowledge schema, knowledgeVersion and server version.
knowledgeVersionYesActive knowledge release identifier from its manifest; not the API contract or MCP/registry server version.

  2. First observed

TDQS

A4.7/5.0
Behavior5/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, and the description adds significant behavior beyond those: unknown valid keys return TERM_NOT_FOUND, uppercase/spaced inputs fail validation before normalization, calls consume rate limits, and no knowledge writes occur. There is no contradiction with the annotations.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is dense but efficient, front-loading the core action and input format, then handling routing, error behavior, access, and rate limits in a compact sequence. Every sentence contributes distinct information, and nothing is redundant or filler.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a single-parameter read tool with a full output schema and safety annotations, the description covers input format, validation failure mode, unknown-key behavior, sibling routing, access level, and rate-limit impact. An agent has everything needed to decide whether and how to invoke this tool correctly.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, and the schema already documents the termKey format, pattern, length, examples, and the fact that uppercase/spaced/fuzzy inputs fail validation. The tool description mainly restates these constraints rather than adding new parameter-level meaning, so a baseline 3 is appropriate.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description opens with a precise verb and resource: 'Read one existing Dutch vehicle definition', and it specifies the exact input form (lowercase slug or term.<slug>). It also explicitly names sibling tools, so an agent can distinguish this from search_vehicle_knowledge, get_answer_context, and get_model_context without inspecting their schemas.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines5/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description gives explicit routing guidance: use search_vehicle_knowledge for free text or unknown keys, get_answer_context for a known answerId, and get_model_context for model-specific context. It also states what this tool does not do ('No fuzzy definition generation'), making when-not-to-use clear.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
