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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and closed-world, so the safety profile is covered. The description adds useful behavior beyond that: reading happens in pages of up to 12,000 characters, implying offset-based paging. It stops short of explaining what happens at end-of-file or what occurs when 'file' is omitted.

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 content is two tight, front-loaded sentences with no filler. The appended Korean restatement adds no information for a single-language agent, slightly diluting conciseness, though it may serve localization.

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 read-only paging tool with no output schema, the description covers the essential prerequisite and page-size constraint. It omits end-of-file/pagination-termination behavior and the role of offset across pages, which an agent consuming a long spec would need.

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 25% across 4 parameters, so the description should compensate more than it does. It does clarify the 'file' parameter by example and effectively documents max_chars' ceiling (12,000 characters), but offset's paging role and slug are left to the schema alone.

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 (read) plus resource (WIA standard specification markdown file), with a concrete example (PHASE-1-DATA-FORMAT.md) and scope (pages of up to 12,000 characters). It is clearly distinguishable from the sibling get_standard, which only lists files.

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?

Explicitly states the workflow prerequisite: 'Use get_standard first to list files.' This routes the agent correctly among siblings, though it offers no when-not-to-use case or guidance for handling a spec that exceeds the page size.

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