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

With no annotations the description carries the full burden, and it does disclose real behavioral constraints: an API key is required and only the filing key (or another key on the same account) can read the report. It also enumerates the possible states and the 'Already reported' case with repeated reference. Missing only rate limits/error behavior.

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?

One dense but front-loaded sentence that leads with what is returned, then the state list, then the permission caveat. No filler, though the parenthetical and nested clauses make it slightly harder to scan than a clean multi-sentence version.

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?

No output schema exists, so the description compensates by enumerating the return states and noting the reply field, plus auth requirements. That is sufficient for a single-parameter read tool; only edge cases like missing/invalid references are left unaddressed.

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 parameter already documents the MT-1042 format, so the schema does the heavy lifting. The description adds only the indirect hint that the ref is the same reference report_data_issue returned, which is useful linkage but not new format detail.

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+resource (check the status of a filed issue) and names the sibling tool that creates the report (report_data_issue), so an agent can tell the pair apart without opening either schema. It even enumerates the possible status values, which no other sibling covers.

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?

Clearly frames the usage context: this is the follow-up to report_data_issue, using the reference that tool returned. It does not explicitly state when *not* to use it or name a competing status-lookup path, but no such alternative exists among the siblings.

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