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

Annotations already declare readOnlyHint, idempotentHint, non-destructive, and closed-world. The description adds real value beyond them: it states no provider request is made and requires tickets:read, plus warns that 'unknown' does not authorize re-reading. It omits return-format/pagination context, so a 3 fits.

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?

Purpose is front-loaded in the first sentence, but 'No provider request.' reads as a dangling fragment and several negative clauses ('is not permission', 'does not prove') take space before saying what the tool returns. Compact but somewhat disjointed.

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 describe return semantics, which it partly does via the cautions about missing/unknown requests. It still leaves the return shape and the meaning/derivation of request_id unexplained, so an agent has gaps for a simple single-param read.

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?

One required request_id with 0% schema description coverage, so the description must carry the load. It implies the id refers to a retained link/check/archive request, but never states the uuid format or provenance of the id, leaving the parameter under-explained.

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 states it reads a retained link/check/archive request result, which is a discernible verb+resource. However 'this owner's exact retained... request result' is cryptic about what the owner is and doesn't clearly distinguish this from siblings like check_ticket_provider_status, check_ticket_provider_fields, or get_ticket_provider_field_options. Adequate but murky.

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 offers behavioral cautions ('an attempted/unknown request is not permission to repeat a remote read') but never says when to use this tool vs. the several sibling provider-status/field tools. No alternatives or explicit triggering conditions are named.

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