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

Annotations already declare destructiveHint=true and idempotentHint=true, so the irreversibility and repeat-safety profile is covered structurally. The description adds a cautionary usage clause but says nothing about permissions, whether deleted entries are recoverable, or how upstream entries are affected.

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?

A single tight sentence with the resource and the caution clause front-loaded; nothing is redundant. It is arguably too terse given the gaps elsewhere, but there is no wasted wording.

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 not be described. For a destructive single-parameter tool, though, the definition leaves the agent without guidance on sourcing entry_id or confirming what deletion entails, which is a meaningful gap.

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% — entry_id has no description — and the description adds no meaning about its format or where the value comes from (presumably from list_translation_memory_entries or search_translation_memory). The description does not compensate for the schema gap.

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 a specific verb and resource ("Delete a translation memory entry"), which is unambiguous and clearly distinct from siblings like update_translation_memory_entry or list_translation_memory_entries. It does not explicitly name those siblings, so it stops 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?

"When explicitly requested" gives a real invocation constraint, implying the agent should not delete speculatively. However, it offers no alternatives (e.g., pointing to update_translation_memory_entry or search_translation_memory for verification before deleting) and no prerequisites such as locating the entry_id first.

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