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

Annotations already declare it read-only, idempotent, non-destructive, and closed-world, so the safety profile is covered. The description adds content scope but does not elaborate on response format, freshness, or limits beyond what annotations provide.

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 compact sentence with no filler and front-loads the subject. The list format is efficient, though it reads as a noun-phrase inventory rather than an explicit action verb.

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 simple informational tool with zero required parameters, full schema coverage, and annotations, the description adequately identifies the covered topics. It could more explicitly state that it returns explanatory answers in the requested language, but no output schema explanation is needed.

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?

The only parameter is lang, and the schema documents it fully with an enum and default. The description adds no language-specific semantics beyond the schema, so high schema coverage sets the baseline at 3.

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 enumerates specific content areas: what ProprioSign does, audience, prices, opening, FAQ, and landlord links, making clear it is an informational about tool. It does not explicitly distinguish itself from sibling guide tools such as read_guide or search_guides, so sibling differentiation is absent.

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 listed topics imply when to use it for ProprioSign-specific questions, including pricing and landlord links. There is no explicit when-to-use/when-not-to-use guidance or named alternative among the sibling tools.

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