get_source_context

Read-onlyIdempotent

Read one public SOURCE or SOURCE_GROUP by exact opaque sourceId to inspect provenance, freshness and limitations. Use search_vehicle_knowledge to discover sources; get_model_context or get_answer_context retrieves the knowledge a source supports. Not a search by URL or source label. Never split composite-looking IDs. Unknown ID returns SOURCE_NOT_FOUND. Public read-only access; no knowledge writes. Calls consume rate limits.

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
sourceIdYesOpaque public SOURCE or SOURCE_GROUP ID, 1–200 characters; lowercase ASCII letters/digits with dot, colon or hyphen separators as specified by the pattern. Copy exactly from sources or search; never split or reconstruct composite-looking IDs.

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 complementary context: public read-only access, no knowledge writes, SOURCE_NOT_FOUND on unknown IDs, and rate-limit consumption. None of this contradicts the annotations, and it goes beyond them with concrete failure behavior.

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 front-loaded with the core purpose, then efficiently covers alternatives, exclusions, error behavior, permissions, and side effects. Each sentence earns its place without redundancy 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-only tool with a full input schema, rich annotations, and an output schema, the description covers discovery, sibling differentiation, exact-ID requirements, failure mode, permissions, and rate limits. Nothing an agent needs to select and invoke it correctly is missing.

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%, so the schema fully documents the single sourceId parameter, including its pattern and length constraints. The description reinforces the 'copy exactly' and 'never split' guidance but does not add materially new parameter meaning beyond what the schema already provides.

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 specifies a concrete verb and resource: 'Read one public SOURCE or SOURCE_GROUP by exact opaque sourceId to inspect provenance, freshness and limitations.' It also differentiates this tool from siblings by stating it is not a search by URL or label and by pointing to get_model_context/get_answer_context for the knowledge a source supports.

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 to discover sources, and use get_model_context or get_answer_context to retrieve the knowledge a source supports. It also gives clear operational constraints: match by exact sourceId, never split composite-looking IDs, and do not use as a URL/label search.

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