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

Annotations already declare readOnlyHint, idempotentHint, and destructiveHint=false, so the description's main job is filling in semantics — and it does: it enumerates all ten status values, specifies that 'a consultation counts only when confirmed', and promises failed/cancelled messages are shown rather than hidden. 'Stores nothing; sends no reminders' adds a useful side-effect guarantee, though the closing sentences about referral/placement are product positioning rather than behavior an agent needs.

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 trigger and return contract are front-loaded and dense with useful detail, but the trailing sentences ('This is a listing service, not a lawyer referral service. No lawyer pays for placement or ranking of any kind.') are promotional boilerplate that does not help an agent decide or invoke, diluting an otherwise tight definition.

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 carries the return-value burden and does so well: statuses, the lawyer's decision, a timeline with attribution, and counts. For a read-only two-parameter batch lookup this is close to sufficient; the only gap is guidance on what to do when an item fails validation or a token is rejected.

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 schema already documents contact_request_id, status_token, the 1–10 items bound, and the optional brief_id labelling purpose. The description restates the 'up to 10, each with its private status_token' framing but adds no new format or sourcing detail beyond what the schema provides, so 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 gives a specific verb and resource: report where things stand for messages the person sent to lawyers, with a concrete bound of 'up to 10, each with its private status_token'. It reads clearly as a batch status-listing tool, though it never distinguishes itself from siblings like get_contact_request_status or get_referral_status, which an agent could easily confuse it with.

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 trigger is explicit ('Use when the person asks where things stand with the messages they sent to lawyers through ESQ CoPilot'), which is a solid when-to-use statement. However, no alternatives are named and no when-not-to-use condition is given, so routing against the similarly named status tools is left to inference.

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