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

With no annotations provided, the description must carry the behavioral burden. It discloses that the return is full article text including Q&A, which tells the agent what comes back, but it says nothing about read-only nature, authentication, missing-slug errors, or how a URL is resolved versus a slug.

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?

Two short sentences, front-loaded with what is returned, followed by parameter guidance. No filler, though the second sentence reads as a terse fragment rather than a fully formed instruction.

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?

For a single-parameter retrieval tool with no output schema and no annotations, the description covers the essential facts: the returned content and the two accepted input forms. Error behavior and output shape are unaddressed but are minor for this complexity level.

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 coverage is 0% and the schema only has a bare 'Slug Or Url' title, so the description must compensate, and it does: it explains that slug_or_url accepts either a slug obtained from usilitel_articles or a direct article address. It could go further on format expectations, but the dual-mode semantics are made clear.

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 specific resource and scope: it returns the full text of a blog article, including its Q&A content. This distinguishes it from the sibling usilitel_articles, which is referenced as the source of slugs, though the differentiation is implied rather than stated outright.

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?

Usage is implied through the reference to usilitel_articles as the place to obtain a slug, which suggests a two-step list-then-fetch flow. However, there is no explicit statement of when to use this tool versus usilitel_page_text or usilitel_content_search, and no exclusions.

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