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

Annotations already declare destructiveHint=true, idempotentHint=true, and readOnlyHint=false, so the safety and idempotency profile is covered. The description adds one meaningful piece beyond that: 'Reuse idempotencyKey', telling the agent how to exploit idempotency on retries. It does not state what exactly is destroyed or any permission requirements.

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?

Two short sentences, front-loaded with the action and scope, with no filler. The idempotency note is terse but earns its place; wording could be marginally clearer.

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 explanation, and annotations cover the destructive/idempotent profile. However, for a 3-required-param destructive mutation at 0% schema coverage, the description leaves the brandId/savedId inputs and failure modes unaddressed, making it only minimally adequate.

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 carries the parameter burden, yet it only gestures at idempotencyKey ('Reuse idempotencyKey') and never explains brandId or savedId semantics beyond implying them. Two of three required parameters remain undocumented in plain language.

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 (remove) and resource (saved ad) and scopes it to 'this brand's inspiration collection', which separates it from read/lookup siblings like list_saved_ads. It does not explicitly contrast with similarly named deletion siblings such as delete_intelligence_saved or delete_ad_watch, so it falls short of full sibling differentiation.

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 over alternatives (e.g. delete_intelligence_saved), nor any prerequisite or context statement. 'Reuse idempotencyKey' is a retry instruction, not a when-to-use criterion.

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