get_invoice_line_items

Read-only

WHAT: www pointer only — invoice line items are computed on www MCP. maps accepts situationKey/whenKey/breakdown for symmetry but returns html link to /preise, not totals. DOES NOT return totalEur. NEXT: @ikeytz/mcp get_invoice_line_items; get_ort_datetime here for Berlin clock/whenKey.

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
localeNomaps is German-only (de). Omit or pass de. Other values are ignored; URLs stay https://maps.ikeytz.com/… with no locale prefix. Not a www multi-locale switch — use @ikeytz/mcp list_locales on www for en|fr|ru|fa|ar|tr.de
whenKeyNoday|night|now — used on www; maps only points.
breakdownNowww flag; ignored for maps pointer payload.
situationKeyYesRequired for www. Situation id (opening_slam, opening_locked, pkg_key_*, cylinder_only, cylinder_mount, aliases).

  2. First observed

TDQS

A4.7/5.0
Behavior5/5

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

Annotations only declare readOnlyHint; the description goes well beyond that by disclosing that the tool returns no totalEur, ignores whenKey/breakdown for the pointer payload, is German-only, and leaves URLs without a locale prefix. These are exactly the unexpected behaviors an agent needs to know.

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

Conciseness4/5

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

Three dense sentences with WHAT/NEXT labels and front-loaded scoping; no filler. One minor deduction because the 'NEXT:' line is a slightly cryptic developer-style pointer rather than a plain instruction, though it remains informative.

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?

The description, schema, readOnly annotation, and output schema together cover return type, ignored params, locale behavior, and the correct alternative tool. It is complete for a pointer tool, but the situationKey requirement ambiguity and the unexplained 'Berlin clock/whenKey' reference keep it from being fully self-sufficient.

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 covers 100% of parameters and already documents locale, whenKey, breakdown, and situationKey. The description adds useful 'for symmetry' semantics that the params are mostly ignored in the maps pointer payload. However, the situationKey description says 'Required for www' while the schema marks it required here, leaving some ambiguity about whether/how it is required on maps.

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 immediately identifies the tool as a 'www pointer only' and states exactly what it returns: an html link to /preise, not totals, and explicitly 'DOES NOT return totalEur.' This distinguishes it from the actual @ikeytz/mcp get_invoice_line_items tool and from siblings like get_prices.

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?

It names the proper alternative for real invoice line items ('NEXT: @ikeytz/mcp get_invoice_line_items') and routes whenKey/Berlin-clock needs to get_ort_datetime here. The 'maps accepts ... for symmetry' phrasing tells the agent this maps tool is only for pointer/link purposes, giving clear when-to-use versus when-not-to-use guidance.

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