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

The annotations already declare destructiveHint=true and idempotentHint=true. The description adds the missing part of the safety profile: the operation requires a preview step and an owner-approved confirm:true reusing the same requestId, which is real procedural information the annotations do not convey. The phrase 'Claim live only when status is active' is opaque and adds little clarity.

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?

The description is short and front-loads the action, but two sentences are wasted: 'Fields: soclo://tools/...' is an opaque pointer that gives the agent nothing actionable, and 'Claim live only when status is active' is undefined jargon. Real content is roughly one sentence.

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, open-world mutation, the description covers the approval workflow well, but it leaves the entity lifecycle unclear: what a 'claim' is, whether removal is reversible, and what status active refers to. There is no output schema, yet the agent is told to recover outcomes by requestId without explanation of how.

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?

With only 50% schema description coverage, the description does not compensate: it restates confirm:true and requestId reuse, which the schema already documents, and says nothing about accountId, platform, parameter placement, or keywordId. The schema's nested parameters object and required keywordId are left for the agent to discover on its own.

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: 'Remove a Search keyword.' That distinguishes it from update_ad_keyword and list_ad_keywords, but it does not differentiate it from the family of negative-keyword removal tools (e.g. remove_campaign_assets, create_ad_negative_keyword_list), leaving ambiguity about which keyword type is being deleted.

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 description gives a clear operational sequence: 'preview, then owner-approved confirm:true with the same requestId.' That covers when to call it in the workflow. However, it never names an alternative or exclusion, such as pausing a keyword with update_ad_keyword instead of deleting it, so the agent must infer when removal is preferable.

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