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

Annotations already declare readOnlyHint, idempotentHint and destructiveHint=false, and the description adds non-obvious operational facts beyond them: it uses no search allowance and does not consume quota. It also states what the tool returns (the recorded boundary and permitted alternatives), which matters for an agent deciding whether to spend a call.

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 critical 'Call this FIRST' routing instruction and trigger list are front-loaded and every clause carries routing or behavioral information. The two opening disclaimer sentences are somewhat repetitive of each other ('Not affiliated...' / 'Not a U.S. government service'), costing a little density.

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?

An output schema exists so return values need not be explained, parameters are fully documented in the schema, and the description covers trigger conditions, cost/behavioral profile, and the negative constraint against using research tools. Nothing an agent needs to invoke this correctly is missing.

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% with an enum whose values are fully documented in the schema, so parameter meaning is already carried by structured data. The description adds no per-parameter detail (e.g. how notice_reference is used beyond echoing), so the 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 and outcome: it returns the recorded policy boundary plus what GovInbox can do instead. The disclaimer sentences and the explicit 'do not research or use memory' line separate it cleanly from the research/search sibling tools.

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?

Gives an explicit trigger ('Call this FIRST whenever...') followed by enumerated conditions that map directly onto the request_type enum values. It also names the alternatives it replaces ('do not research or use memory to answer these requests'), which is exactly the when/when-not guidance an agent needs.

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