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

Annotations already declare readOnlyHint=true and destructiveHint=false, so the safety profile is covered; the description adds genuinely non-redundant context by stating OAuth plus the 'share_results' permission is required. It also reveals the identity/visibility scope ('my' cases) and the state vocabulary, though it says nothing about pagination or result volume.

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?

Three tight sentences with zero filler, though front-loading the OAuth/permission prerequisite ahead of what the tool actually does slightly delays the agent's primary read; the purpose could have come first.

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 correctly steps in to list the returned fields, which is the main completeness need. However, an undocumented filtering parameter and absent pagination/result-size guidance leave a real hole for a list operation.

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 0% and the single optional parameter subject_id is never mentioned in the description, so an agent gets no clue whether it filters by person, workspace, or something else. The description must compensate for a 0%-coverage schema and does not.

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 opens with a specific verb+resource ('Lists removal cases') and enumerates the returned fields (site, action, request status, verification status, human-only steps, dates), which clearly separates it from singular siblings like get_case_status. It stops short of naming an alternative, but the scope is unambiguous.

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 implied by 'my removal cases' and the note that filed/pending/needs review/verified removed are distinct states, but there is no explicit when-to-use versus when-not, and no routing to get_case_status or list_my_subjects for narrower questions.

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