Latest Release

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

With no annotations, the description carries the behavioral transparency burden and does a good job by disclosing that the next release date is only an estimate and not authoritative, with DOSM's calendar as the source of truth. It also explains the estimate is derived from frequency and typical release lag, which adds useful context beyond the bare tool name.

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

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

The description is two sentences with no filler. The main purpose is front-loaded, and the important caveat about the estimate being non-authoritative is placed immediately after.

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

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

The tool has only one parameter and an output schema, so the description does not need to detail return values. However, it omits any guidance on when to choose this tool over sibling tools and leaves series_id semantics underspecified, making it minimally viable but not fully complete.

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

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

Schema description coverage is 0%, and the description does not explain what series_id should be, its format, or how to find valid values. The only hint is the phrase 'for a series,' which is marginal and does not compensate for the lack of schema documentation.

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

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

The description clearly states that the tool returns the newest available data point for a series and adds an estimated next release date. It identifies the specific resource (a series) and the core function, but it does not explicitly distinguish itself from sibling tools like get_series or describe_series.

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

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

The description does not specify when to use this tool over alternatives such as get_series or compare_series, nor does it mention any exclusions or prerequisites. The intended use is implied by the name and description, but no direct guidance is provided.

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