li_list_creatives

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

No annotations provided, so description carries full burden. Describes returned fields and filtering behavior. Lacks mention of pagination beyond page_size parameter, rate limits, or error handling, but overall is transparent about the tool's read-only nature and output.

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?

Three concise sentences, front-loaded with purpose, no redundancy. Every sentence adds value.

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?

Covers purpose, usage, and return fields adequately for a list tool with no output schema. Provides sibling guidance. Missing default ordering or pagination details (though page_size parameter exists), but overall sufficient.

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 already describes campaign_id and status well. Description adds practical usage context ('see all creatives on a specific campaign', 'find paused/archived ads'), enhancing parameter meaning beyond schema. However, does not elaborate on ad_account_id or page_size beyond schema.

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?

Clearly states the verb 'List' and resource 'ad creatives in a LinkedIn ad account'. Explicitly lists return fields (creative content type, intendedStatus, campaigns, content URNs) and distinguishes from sibling li_get_creative, which provides full detail on a single creative.

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?

Provides explicit when-to-use guidance: filter by campaign_id or status. Directs to li_get_creative for detailed content, which prevents misuse and clarifies alternative.

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