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

Annotations already establish readOnlyHint, idempotentHint, and non-destructiveness, so the safety profile is covered. The description adds minor scoping ('published', 'canonical service') but does not disclose return format, pagination, auth needs, or error behavior. It is consistent with the annotations and does not contradict them.

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, front-loaded sentence with no filler. It adds the qualifiers 'published' and 'canonical' beyond what the title alone conveys. It is concise, though somewhat under-specified; the structural style itself is sound.

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?

Given the lack of an output schema, 0% parameter coverage, and a large set of sibling tools, the description leaves important gaps. It does not explain what 'deliverable context' includes, how serviceId is sourced, or when this tool should be preferred over related get_* tools. An agent would likely need external context to invoke it confidently.

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?

With schema description coverage at 0%, the description must compensate for missing parameter explanations, but it does not. It only vaguely hints that serviceId refers to a 'canonical service' without explaining how to identify or format it. The locale parameter's behavior and default are left entirely to the schema.

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 uses a specific verb and resource: 'Return published deliverable context for a canonical service.' It clearly identifies what the tool returns and distinguishes it from sibling tools by focusing on deliverables rather than prices, cases, facts, or other resources. However, it does not explicitly differentiate itself from siblings by name, and 'canonical service' is somewhat unexplained.

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 guidance is provided about when to use this tool versus alternative sibling tools. The description does not mention scenarios, exclusions, or alternatives, and there are many similarly named get_* tools. The 'published' qualifier implies some limitation, but it is not developed into actionable usage guidance.

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