get_last_available_month

Find the month and year of the most recently published heating and hot-water consumption report. Returns the coverage period without fetching the full report.

Instructions

Return the month and year of the most recently published consumption report.

messdienst24.de is a German utility-consumption portal that provides the legally mandated monthly heating and hot-water consumption report (Verbrauchsinformation) for residential properties. The portal publishes one report per calendar month (always a previous month, never the current one). This tool returns which month that currently published report covers.

Call this tool when you only need to know the current reporting month without fetching the full report. The full report (get_consumption_report) and the PDF (save_pdf) both include this information as well.

Returns: year: Four-digit year of the current reporting month (e.g. 2025). month: Month number 1–12 of the current reporting month (e.g. 4 for April).

Behavior5/5

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

No annotations are provided, so the description carries the full burden. It explains the portal context, publication frequency (previous months), and what the tool returns. It is consistent with a read-only operation and discloses the return type and structure.

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 well-structured with a clear statement of purpose, background context, usage guidance, and return value specification. It is appropriately sized with no wasted sentences.

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?

Given zero parameters and a simple return structure, the description fully defines the tool's input and output. It provides domain context and sibling differentiation, making it complete for an agent to decide and invoke.

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?

There are no parameters (0 params), so baseline is 4. The description does not need to add parameter info as there are none. It implicitly covers all required input.

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 clearly states it returns the month and year of the most recently published consumption report. It uses a specific verb ('Return') and resource ('month and year'), and distinguishes from siblings by noting that the full report and PDF also include this information.

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?

Explicitly states when to use this tool: 'Call this tool when you only need to know the current reporting month without fetching the full report.' It also mentions alternatives (get_consumption_report, save_pdf) that contain the same info.

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