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

Annotations already declare readOnlyHint=true, destructiveHint=false and openWorldHint=false, so safety is covered structurally. The description goes beyond them by promising sort order (newest first), the aggregate counts bundled into each row, and a presentation rule that UUIDs must never be shown to the user — behavioral detail annotations cannot carry.

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?

It is two sentences: the first describes the payload and sort order, the second covers how to consume the ids and how to render entities to the user. Front-loading is good and there is no filler, though the user-facing UUID rule is generic guidance that sits slightly apart from this tool's specific behavior.

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 no further explanation, and the parameterless input is fully covered. The description is nonetheless complete enough to call correctly and to chain into workflow setup; only minor gaps remain, such as what is returned when no translation memories exist.

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?

The tool takes zero parameters, so there is nothing for the description to disambiguate; the 4 baseline applies. The description still adds value by clarifying what comes back per row and what the id field means for later calls.

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 names a specific resource (the organisation's translation memories) and discloses ordering (newest first) plus the returned per-item metrics (entry count, project and Workflow usage counts). It does not explicitly contrast itself with search_translation_memory, so an agent must infer why it would pick a plain listing over a search, which keeps it short of a 5.

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 only explicit guidance is downstream: the ids returned are the translationMemoryId that preview_workflow_setup and set_up_workflow accept, which usefully chains this tool to the next step. There is no statement of when to call this versus search_translation_memory or list_glossary, and no exclusions or prerequisites, so usage is only implied.

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