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

Annotations already declare destructiveHint=true, idempotentHint=true and openWorldHint=true, so the safety profile is covered structurally. The description adds nothing beyond that: it does not say whether the delete is hard or soft, what happens if the entry does not exist, or whether both identifiers may be supplied. Not a contradiction, but thin for a destructive operation.

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 front-loaded sentence with the verb, resource and both accepted keys; no filler, no repetition of the title. Every clause earns its place.

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?

For a destructive tool with no output schema and 0% schema description coverage, the definition leaves key decisions undocumented: which identifier wins, whether at least one is mandatory, and what a successful delete returns or confirms. An agent could invoke it but not confidently handle the ambiguous cases.

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%, so the description must carry the weight — and it does disclose that the two identifiers are alternatives ("or"), a relationship the flat schema does not express. However, it does not resolve precedence if both are passed, nor address that required parameters is 0, leaving the agent unsure whether omitting both is legal.

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 and resource ("Delete a gservice_indexer entry"), which unambiguously separates it from list_gservice_indexer, create_gservice_indexer, send_gservice_indexer and submit_gservice_sitemap in the sibling set. It stops short of explicitly naming an alternative, but the operation is clear.

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?

There is no guidance on when to use this versus alternatives, no preconditions (permissions, ownership), and no statement about irreversibility or recovery. The only hint of usage is the "by `gservice_indexer_id` or `gservice_indexer_uuid`" clause, which is really parameter semantics rather than when-to-use guidance.

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