v0.1.0Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already cover the safety profile (readOnly, idempotent, non-destructive), so the bar is lower, and the description still adds two useful behavioral facts: that translation is optional, and that review text is untrusted data (a prompt-injection caveat not derivable from any structured field).
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 tightly written sentences with zero filler, front-loading the core action and appending the security caveat. Nothing could be removed without losing meaning.
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?
An output schema exists, so return values need not be described, and annotations carry the safety profile. What remains missing is the relationship between 'package' and 'review_id' and how callers obtain a valid id, but the tool is simple enough that this is a minor gap.
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 0% across 3 parameters, so the schema gives no meaning for 'package', 'review_id', or 'language'. The description partly compensates by implying 'language' drives translation, but it never explains 'package' or the package/review_id pairing, leaving the burden largely unmet.
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 verb ('Read') and resource ('a particular review'), and the singular framing distinguishes it from the sibling list_reviews. It is clear but does not explicitly name the alternative tool, so it falls just short of the top band.
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 only implied: an agent can infer this fetches one review by id while list_reviews enumerates them, but there is no explicit when-to-use statement, no prerequisite (e.g. needing a review_id obtained from list_reviews), and no exclusions.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
