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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and openWorldHint=false, and the description is consistent with that closed-corpus, safe-read profile. It adds real value beyond the annotations by disclosing the return shape (id, title, short summary, links) and clarifying that the catalog is WIA's own standards rather than ISO/IEC. Pagination behavior via limit/offset is not described.

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 English portion is front-loaded and waste-free: purpose, scope boundary, then return fields. The appended Korean sentence is a pure duplicate of the first clause and adds no new information, a minor redundancy rather than a structural flaw.

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?

There is no output schema, so the description correctly spends its words on return fields, and the annotations cover the safety profile. For a simple read-only search tool it is nearly complete, with the only real gap being pagination/limit semantics and sibling routing.

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% – query has an example, but limit and offset carry no descriptions at all. The description never compensates: it says nothing about query syntax, result capping, or how offset pagination should be used, so an agent has no guidance on two of the three parameters.

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?

States a specific verb and resource ('Search the WIA standards catalog') and scopes the corpus as hundreds of WIA-authored specifications across industries. It also draws a useful boundary against external corpora ('not ISO/IEC international standards'), though it never names a sibling tool such as get_standard or get_catalog_stats for follow-up retrieval.

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 gives no when-to-use or when-not-to-use guidance and no routing against the three sibling tools. An agent must infer on its own that this is the discovery step and get_standard is the fetch step.

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