Get Widerruf

get_widerruf

TableJSON Schema

Name	Required	Description
`ok`	Yes	true = use summary, canonicalUrl, and extra keys. false = do not invent data; read error + hint and retry with valid args or open hint.
`npm`	No	www CLI package @ikeytz/mcp
`hint`	No	Present when ok=false. Absolute URL or short recovery hint the agent should open or pass to another tool.
`html`	No	Absolute www.ikeytz.com URL — open there or call @ikeytz/mcp
`note`	No	maps only points; Volltext/Preise/FAQ live on www
`tool`	Yes	Echo of the tool name that produced this object (e.g. get_service_area).
`error`	No	Present when ok=false. Codes include: unknown_place, unknown_discovery, unknown_doc, q_required, plz_required, coords_required, outside_service_area, url_required, not_maps_host, bad_url, path_or_url_required, serp_not_found, slug_or_coords_required, path_required.
`locale`	No	Locale actually used for URLs. maps is German-only: always de (MAPS-E8 — no /en on maps). Requested non-de is ignored; payload locale=de.
`related`	No	Always includes https://maps.ikeytz.com/llms.txt.
`summary`	No	Primary text for the model. For discovery tools this is the file window. For list tools a compact one-liner. Quote with attribution.
`www_mcp`	No	https://www.ikeytz.com/mcp — sister machine for prices/FAQ/corpus
`www_tool`	No	Same tool name on www MCP that holds the real payload
`attribution`	Yes	Required citation: 'Quelle: Schlüsseldienst Ludwigsburg ikeytz (ikeytz.com) · ai-train=no · https://maps.ikeytz.com/.well-known/ai.txt'
`canonicalUrl`	No	Best URL to show the user: https://maps.ikeytz.com… page, public embed JSON, tel:+49…, mailto:…, https://wa.me/…, or a www pointer. Prefer this over constructing URLs.
`requested_locale`	No	Locale the caller asked for; maps still returns locale=de

TDQS

A4.1/5.0

Behavior4/5

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

Annotations already declare readOnlyHint=true, so safety is covered. The description adds genuinely useful behavioral context beyond that: it returns a URL only (no policy prose) and 'DOES NOT invent clauses', which is a meaningful hallucination guardrail for an agent.

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?

Uses a clean WHAT/USE/DOES NOT structure, front-loading the key fact (URL only). Every sentence earns its place, including the terse guardrail against inventing clauses.

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

Completeness4/5

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

With an output schema present, return format need not be explained, and zero params mean no schema gaps. The definition covers what it returns, when to use it, and its limits. Only the ambiguous cross-reference to the 'www MCP' variant keeps it from being fully self-contained.

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

Parameters4/5

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

The tool takes zero parameters, so there is nothing for the description to disambiguate – baseline 4. The schema itself confirms no-argument invocation, and the description does not need to add parameter detail.

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

Purpose4/5

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

States a specific verb and resource ('Returns only a URL to www Widerruf') and even bounds the scope by contrasting with 'withdrawal-policy text.' It distinguishes itself from content siblings like get_legal. The phrase 'Prefer www MCP get_widerruf' is confusingly self-referential, slightly muddying what this variant actually is.

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

Usage Guidelines4/5

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

Explicitly states the condition ('when the user asks for Widerruf while on maps and you only need the link') and names alternatives (get_legal, the www MCP tool). Only weakness is that the named alternative 'www MCP get_widerruf' does not appear in the sibling list, so the routing is not fully resolvable from the definition alone.

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