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

Annotations already declare readOnlyHint=true, destructiveHint=false, openWorldHint=true, and idempotentHint=false, but the description adds nothing behavioral on top of them — no mention of pagination semantics, no note on whether an unknown ID errors versus returns an empty report, no hint about the `filters` object in the response. For a read-only report fetch with annotations covering safety, this is a bare minimum contribution.

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 description is a single short sentence with zero wasted words, which is structurally clean. However, its brevity reflects under-specification rather than disciplined concision — there is no front-loaded scope, no pagination note, and no boundary statement to anchor the agent.

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?

With 6 parameters, a required `id`, no output schema, and no annotations explaining return shape, the description should at least say where the report ID comes from and that results are paginated with a `filters` block enumerating valid version/event-type IDs. None of that is present, so the definition is not complete enough for the tool's complexity.

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 100%, with each of the 6 parameters, including pagination and the `[min, max]` threshold shape, documented in the schema itself. The description adds no meaning beyond that, so the baseline of 3 applies rather than a higher score.

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 "Show a character attribute report" essentially restates the tool name (get_character_attribute_report) with no added specificity. It does not distinguish this tool from close siblings such as get_attribute_report, get_character_report, or list_character_attribute_reports, so an agent cannot tell from the text alone which one returns a saved per-character attribute report by ID.

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 when-to-use guidance, no statement of prerequisites (e.g., that the `id` comes from list_character_attribute_reports), and no mention of alternatives like get_attribute_report or list_character_attribute_reports. The agent must infer usage entirely from the name and schema.

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