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

With no annotations provided, the description carries the full burden of behavioral disclosure. It states what the tool returns (entities, strengths, conclusion, FAQs) and the source (getrecon.xyz), but doesn't address important behavioral aspects like error handling, rate limits, authentication requirements, or whether this is a read-only operation. The mention of 'source' adds some context but leaves significant gaps.

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 appropriately concise with two sentences that each serve a purpose: the first states the core functionality and return values, the second provides source attribution. It's front-loaded with the main purpose. However, the second sentence about the source could be integrated more smoothly with the first.

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 read operation with no output schema, the description provides basic completeness by stating what's returned. However, it lacks important context about the return format structure, error conditions, or how to interpret the returned data. Without annotations or output schema, the description should do more to explain the tool's behavior and results.

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% for the single parameter 'slug', which is well-documented in the schema. The description doesn't add any parameter information beyond what's already in the schema. This meets the baseline of 3 when schema coverage is high, but the description provides no additional parameter context or examples beyond the schema's example.

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 the tool's purpose: 'Get a comparison article by slug' specifies the verb (get) and resource (comparison article). It distinguishes from siblings like get_blog_post or get_book_chapter by focusing on comparison articles. However, it doesn't explicitly differentiate from search tools that might also retrieve comparison content.

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 provides no guidance on when to use this tool versus alternatives. It doesn't mention when to choose get_comparison over search_all, search_site, or other search tools that might find comparison articles. There's no context about prerequisites, limitations, or appropriate scenarios for use.

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