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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false and openWorldHint=true, so the safety profile is covered. The description adds only the fact that the response embeds the scenario's saved assessments. It says nothing about error behavior for unknown IDs or cross-company access restrictions.

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 front-loaded sentence with no padding, which is appropriate in size. It loses a point only because the sentence duplicates the title verbatim rather than adding new information.

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 two-required-UUID lookup with no output schema and no parameter descriptions, the definition is too thin: it doesn't describe the shape of the returned assessments, what happens when the scenario does not exist, or how to source the identifiers.

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%: both parameters are bare UUID strings with only format/pattern constraints. The description does not explain what 'company' identifies, whether 'scenario' must belong to that company, or where an agent obtains these IDs, so it fails to compensate for the coverage gap.

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 (read) and resource (one scenario), with 'one' implicitly distinguishing it from summer_quality_scenarios_list and 'read' from summer_quality_scenarios_save. The phrase 'its saved assessments' also signals that child assessments are returned. However, no sibling is named explicitly and the sentence essentially restates the title.

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?

There is no guidance on when to use this versus summer_quality_scenarios_list or summer_quality_scenarios_save, and no prerequisites (e.g., needing an existing scenario or its UUID). Usage must be inferred entirely from the tool name.

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