get_article_page

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

Annotations already declare readOnlyHint=true and openWorldHint=false, so safety is covered. The description contributes the genuinely useful 0-indexed paging convention, but says nothing about what a 'page' contains, whether it re-fetches from the network or reads from cache, or what the response looks like.

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?

A single tight sentence with zero waste; the core action comes first and the paging convention follows immediately.

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 output schema and three required parameters, the description should carry more weight. It covers the paging model adequately for a simple read, but leaves 'uid' and the nature of a page undefined, which an agent needs in order to call this correctly.

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 only 33% — only run_id is documented in the schema. The description compensates for exactly one gap by explaining that pages are numbered from 0, which is real added meaning for 'page', but 'uid' remains completely unexplained in both the schema and the description.

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 states a specific verb and resource: re-reading one page of an already-fetched article. It distinguishes itself from fetch_articles and list_articles via the word 're-read,' but it never names a sibling or clarifies the relationship, so the differentiation is implied rather than explicit.

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?

'Re-read' implies the usage context (after an article has already been fetched), which is useful but inferred rather than stated. There are no explicit when-to-use/when-not conditions and no naming of alternatives such as fetch_articles for a first read.

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