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

Annotations already declare readOnlyHint=true, idempotentHint=true, openWorldHint=false, and destructiveHint=false, so the safety profile is fully covered by structured fields. The description adds useful behavioral context by disclosing that assumptions carry check dates and that the model has explicit deliberate non-goals, which goes somewhat beyond the annotations, but it says nothing about response shape or scope beyond the listed contents.

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?

A single, dense sentence with no filler, front-loaded with the resource and its contents. It borders on a run-on list, but every clause earns its place by naming a distinct artifact the tool returns.

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, single-param, no-output-schema tool the description is roughly adequate: it tells the agent what content comes back and confirms the model's deliberate scope limits. It still lacks usage routing and any statement of scope or freshness needed to place it among the six siblings.

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 coverage is 100% and the single enum parameter (lang) is fully documented with allowed values and a default. The description adds no parameter-specific detail, but with zero required params and complete schema documentation, the baseline expectation is met, and the enum constraint is the only param semantic that matters.

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 the resource and enumerates its specific contents (level definitions, formulas, assumptions with check dates, the verbal probability scale, and deliberate non-goals), which clearly distinguishes it from siblings like get_changelog or get_overview. However, the tool name already implies 'methodology' and the description omits a stated verb (e.g., 'retrieve'/'return'), leaving the action implicit.

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 when-to-use or when-not-to-use guidance is provided. The description never routes the agent to alternatives or states the conditions under which this tool is the correct choice, despite having six sibling tools that could plausibly overlap.

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