Read one testimonial

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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false, and openWorldHint, so the safety and access profile is covered. The description adds that the read includes native video metadata plus public/dashboard links, which is useful context about what it returns, but says nothing about permissions, error cases, or rate limits.

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 sentence that front-loads the action and resource and wastes nothing. Appropriately sized for a two-parameter read tool.

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 annotations covering safety and schema at 100% coverage, the core is complete. But the description hints at a rich return payload (native video metadata, public/dashboard links) with no output schema, so it stops short of telling the agent what it will receive or when this read is preferable to list_testimonials.

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%, so the two parameters are fully documented in the schema itself, including the account label caveat and the traversal guard on testimonial_id. The description adds no param-level meaning, which matches the baseline when the schema does the heavy lifting.

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 exact testimonial') with singular scope, distinguishing it from the sibling list_testimonials. However, it doesn't name or contrast any alternative for retrieving a testimonial by ID, so sibling differentiation is only 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 guidance, no prerequisites, and no mention of alternatives. The description never signals that list_testimonials is for enumeration while this is for a single lookup, leaving the agent to infer routing.

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