ntsa_services_guide

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

The readOnlyHint annotation already establishes this is a safe read operation. The description adds only modest context: the 'DEMO' flag indicates it may be a sample/limited tool, and the topic list provides scope. No contradictions with annotations are present, but no deeper behavioral details (e.g., return format, limitations) are given.

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 very concise and front-loaded with the tool name and topic list. Every phrase adds value, including the 'DEMO' note. It could be slightly more structured to separate the tool's purpose from its parameter hints, but overall it is efficient.

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 simple one-parameter schema and presence of an output schema, the description covers the main purpose and parameter domain. However, it does not mention whether any default service applies, how many services exist, or what to expect in the response (e.g., a static guide vs. dynamic data). The DEMO note hints at limitations but doesn't fully explain behavior.

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% and no enums, the description is the primary source of meaning for the 'service' parameter. It lists the likely acceptable values ('driving licence, vehicle inspection, permits'), which is essential for an agent to construct a valid request. This substantially compensates for the sparse 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 clearly identifies a resource ('NTSA services guide') and lists the topics it covers (driving licence, vehicle inspection, permits). It partially distinguishes from sibling tools by specifying this is the NTSA-related guide, though it could state its function as a verb (e.g., 'provides information about').

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?

The description implies usage for questions about NTSA services like driving licences, vehicle inspection, or permits. However, it does not explicitly say when to use this guide over sibling tools like matatu_route_finder or boda_licensing_guide, leaving some ambiguity.

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