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

Annotations already declare the safe read-only, idempotent, non-destructive profile. The description adds useful behavioral context beyond them: the return payload includes a README excerpt capped at 4,000 characters, a spec file list, and ebook languages/links. No auth or rate-limit details, but those are not crucial for this simple read.

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 a single front-loaded sentence that earns its place by listing the returned items. The appended Korean translation duplicates the purpose and is the only minor waste.

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 one-parameter read-only tool with no output schema, the description gives the essential purpose and return contents, and annotations cover safety. It lacks sibling routing guidance or error behavior for an invalid slug, leaving a small 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%, so the description should compensate. It states the parameter is a 'slug', which mirrors the schema property name and adds minimal semantic meaning; format constraints (pattern, maxLength) remain only in the schema.

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?

Specific verb+resource ('Overview of one WIA standard') and enumerates the returned contents (README excerpt, spec file list, ebook languages/links), which differentiates it from search_standards and read_standard_spec.

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?

No explicit when-to-use, when-not-to-use, or alternative tools are named. The description implies it is for retrieving a standard overview, but an agent must infer this from the purpose alone.

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