Get Category History

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

No annotations are provided, so the description carries the full behavioral burden and mostly fails it. 'Concatenated' hints at output shape but is unexplained, and there is no mention of truncation limits, ordering, output size, or whether responses can be huge given up to 100 articles.

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?

It is a single, front-loaded sentence with no filler. Brevity is achieved cleanly, though the sentence is arguably too thin to justify the tool's complexity rather than padded.

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?

With no annotations, no output schema, and a multi-item input that produces a concatenated history payload, the description should explain the output format, limits, and its relationship to get_article_history. None of that is present, so an agent cannot confidently choose or call this tool.

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 100%, so both parameters (lang with its default, article_list with max 100) are already documented in the schema. The description adds no syntax, format, or semantics beyond that, so the baseline 3 applies.

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 names a verb (retrieves) and resource (full revision history) for a list of articles, which is broadly understandable. However, the tool is named get_category_history yet the description mentions no category parameter or category scope, and it does not distinguish itself from the sibling get_article_history — leaving the actual scope ('concatenated' list vs single article) ambiguous.

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?

There is no when-to-use guidance and no indication of how this differs from get_article_history or get_article_recent, despite many closely related history siblings. The agent is left to guess which history tool applies.

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