Compose Whatsapp

compose_whatsapp

Read-only

WHAT: wa.me link with prefab. option = one of 12 www contactOption ids (opening_slam_day … cylinder_only_night, cylinder_mount, beratung). Deprecated aliases zugefallen|abgeschlossen|zylinder map to day and set ambiguous=true — prefer explicit day/night ids. Omit → bare wa.me. Unknown → ok:false unknown_option + hint ids. Link only — no form. USE to open WhatsApp with a prefab. NEXT: compose_mailto, get_contact.

Input Schema

Name	Required	Description	Default
`option`	No	Optional situation id from list_whatsapp_options (12 www ids; aliases deprecated). Unknown → ok:false.

Output 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.
`hint`	No	Present when ok=false. Absolute URL or short recovery hint the agent should open or pass to another tool.
`href`	No	https://wa.me/…
`note`	No	Link only. Kein Formular.
`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.
`option`	No	Resolved option (null if omitted)
`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.
`ambiguous`	No	true if deprecated alias was used
`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.
`deprecatedAlias`	No	Alias used, if any

TDQS

A4.7/5.0

Behavior5/5

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

Annotations only give readOnlyHint=true; the description goes well beyond by disclosing deprecation aliases and their side effect (ambiguous=true), the omit-option fallback (bare wa.me), and the error contract (ok:false unknown_option + hint ids). That is meaningful behavioral context an agent could not infer from the schema or 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?

Telegraphic and front-loaded: WHAT, then parameter semantics, then USE/NEXT. Every clause carries information (aliases, error contract, scope limit) with no 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?

With an output schema present, return values need not be described, and the description still covers the key failure shape (ok:false). For a one-optional-parameter read-only link builder, nothing an agent needs to call it correctly is missing.

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?

Schema coverage is 100%, so baseline is 3, but the description adds real meaning: the option namespace (12 www ids), the deprecated zugefallen|abgeschlossen|zylinder aliases mapping to *day*, and the unknown-value failure mode. It does not enumerate all 12 ids or their distinctions, which caps it below 5.

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?

States a specific verb+resource ('wa.me link with prefab') and makes the artifact type unambiguous ('Link only — no form'). It clearly distinguishes itself from the tel/mailto siblings by naming its channel and its option parameter.

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?

'USE to open WhatsApp with a prefab' plus 'NEXT: compose_mailto, get_contact' gives the calling context and points at sibling alternatives. It stops short of stating when NOT to use it (e.g., no option vs. another channel), so it is strong but not exhaustive.

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