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 profile is covered. The description adds only "Reuse idempotencyKey," which restates the retry-safety idea; it says nothing about permanence, cascading effects, or whether the brand's collection is affected beyond the one item.

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, purpose front-loaded, no filler. Every clause contributes; the idempotency note is placed second where it belongs.

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, and annotations cover the mutation profile. However, with all three parameters undocumented in the schema, the definition is thin for a destructive operation whose inputs an agent must construct correctly.

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 full burden for three required parameters. It only loosely implies brandId ("this brand's") and savedId ("a specific saved ad"), and gives no meaning for the UUID format or the idempotencyKey pattern beyond a vague reuse instruction.

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 ("a specific saved ad") scoped to "this brand's inspiration collection," which is enough to distinguish it from list_saved_ads and save_library_ad. It does not explicitly name any sibling tool, 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?

There is no statement of when to use this versus alternatives like delete_intelligence_saved or when not to delete. "Reuse idempotencyKey" is a retry hint, not selection guidance, so the agent is left to infer the use case entirely.

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