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

Annotations already declare readOnlyHint, idempotentHint, and destructiveHint=false, so the safety profile is covered; the description adds real value by naming the external source of truth (official county roll records) and enumerating the three possible statuses an agent must branch on. It stops short of explaining edge cases such as an order with no matching parcel or how stale a roll check may be.

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 with no filler: the action and data source come first, followed by the enumerated return states. Every clause carries information an agent needs.

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 read-only reconciliation call with no output schema, the enumerated status strings effectively substitute for return-value documentation, and annotations cover safety and idempotency. The only real gap is failure/empty-result behavior when no roll record matches.

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 single order_id parameter is already documented as coming from generate_address_change_packet. The description adds no additional meaning about the identifier's form or constraints, which is the expected baseline when the schema does the work.

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 gives a specific verb ('Reconcile') and resource ('address change orders against official county roll records') plus the three per-parcel outcome states, so an agent knows exactly what the tool produces. It does not explicitly compare itself to nearby tools like quote_address_change or the audit_* family, which keeps it short of a 5.

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?

Usage is only implied: the schema notes order_id comes from generate_address_change_packet, which suggests this is a follow-up verification step, but the description itself never says when to call it versus alternatives or what preconditions exist. No explicit exclusions or routing guidance are present.

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