99 driver track (GPS redacted)

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

Annotations already declare readOnlyHint, openWorldHint, idempotentHint, and non-destructive behavior. The description adds genuinely useful context beyond that: direct driver URLs return 404 HTML, lat/lng are redacted, and the endpoint reads pOrderStatus. It does not detail privacy_mode effects or error cases, but with annotations present the added context is valuable.

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 extremely short with no filler, and each fragment contributes something: the 404 behavior, pOrderStatus, and redaction. However, the phrasing is cryptic and the first clause may confuse rather than clarify, so it loses a point for sacrificing clarity.

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 tool with no output schema and three parameters, this description is insufficient: it does not specify the full return shape, how privacy_mode alters output, or what happens with an invalid or missing ride_id. An agent could infer basics, but the description alone does not provide enough to invoke the tool 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?

Schema description coverage is 0%, so the description must compensate, but it does not explain ride_id, privacy_mode, or response_format. It hints at privacy behavior through 'lat/lng redacted' and names pOrderStatus as the data read, which gives some context, but enum semantics, requiredness, and parameter mapping remain unclear.

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 states a specific verb+resource: it reads pOrderStatus for driver tracking, and the title adds the key qualifier 'GPS redacted'. It is clear in intent, but it does not explicitly differentiate from siblings like ninenine_track_ride or ninenine_active_ride; the 'driver' vs 'ride' naming does some of that work implicitly.

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 explicit when-to-use guidance, no mention of alternatives, and no exclusion criteria. The phrase 'Dedicated driver URLs 404 HTML' implies this tool is more reliable than direct URLs, but it never tells the agent when to choose this over ninenine_track_ride or ninenine_active_ride.

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