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

With no annotations, the description carries the full burden, but it does add real value by disclosing the return vocabulary ('verified_on_roll', 'watching_roll', 'stalled_needs_followup'), which tells the agent this is a read-style reconciliation check. It says nothing about record freshness, permission requirements, or whether it mutates state, leaving gaps for an unannotated tool.

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 leads with the action and then the return contract, with zero wasted words.

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 one-parameter tool with no output schema, the description usefully compensates by enumerating the return statuses, so an agent knows what a call yields. The main shortfall is the absence of usage/routing context, which keeps it from a 5.

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 coverage is 100% and the parameter already documents its origin (generate_address_change_packet), so the description adds no parameter meaning beyond the schema. 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?

States a specific verb (reconcile) and two concrete resources (address change orders vs. official county roll records), and even names the exact status values returned. An agent can distinguish this from write-side siblings like generate_address_change_packet or quote_address_change without opening the schema.

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 gives no explicit when-to-use, when-not-to-use, or alternative-tool guidance. The only routing signal (order_id comes from generate_address_change_packet) lives in the schema, not the description, and no sibling like quote_address_change is mentioned as a contrast.

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