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

Annotations already declare readOnly=false, openWorld=true, idempotent=false, destructive=false. The description goes beyond them by disclosing a rate/quota constraint (max 5 per 90 days, one at a time) and an auth path ('with access (a test account or key)') for measuring past a sign-up wall. This is meaningful behavioral context the annotations don't carry.

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?

It front-loads the core idea and is reasonably short, but the phrasing is dense and awkward ('A new drive after your fixes, with an Audit: up to 5 within 90 days of its report, one at a time'), forcing re-reads. Some clauses could be tightened without losing meaning.

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 no output schema, the description should carry behavioral and usage load, and it does: quota limits, one-at-a-time behavior, the access mechanism, and where to check availability (my_orders). For a two-parameter tool with annotations covering safety, this is largely complete, though the undefined 'drive'/'Audit' terminology is a residual gap.

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 both parameters (order_id, access) are already documented in the schema. The description reiterates the access concept and ties order_id to my_orders, but adds no syntax or format beyond structured data. Baseline 3 applies.

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 conveys that this requests a follow-up 'drive' after fixes, and the title gives it a request verb. However, it never cleanly states verb+resource, and 'drive' is undefined jargon that an agent must infer from siblings like drive_stop and recheck_after_fix. Purpose is recoverable but not crisp.

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?

It implies timing ('after your fixes', 'up to 5 within 90 days of its report, one at a time') and points to my_orders for followup_available/followups_left, which hints at a precondition. But it names no alternatives (recheck_after_fix, drive_stop exist as siblings) and gives no explicit when-not guidance, leaving usage inferential.

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