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

The annotations already declare readOnlyHint=true, destructiveHint=false, idempotentHint=true, and openWorldHint=true, and the phrase 'Read only; no spend' largely restates them. Nothing is disclosed beyond that — no retention window for log entries, no pagination behavior, no note on how far back changes are retained — so the description adds little behavioral context.

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 text is short and the purpose is front-loaded, but the trailing 'Fields: soclo://tools/soclo_ads_get_ads_activity_log' sentence conveys no usable information and reads as template residue. It is brief without being information-dense.

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?

With a nested parameter object, 50% schema coverage, no output schema, and time-window paging parameters that need explanation, this definition leaves the agent unable to construct a correct call confidently. The resource-URI 'Fields' pointer does not substitute for the missing parameter and return-shape guidance.

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?

Six parameters at 50% schema description coverage, including an undocumented nested 'parameters' object (after, limit, since, until, objectId) and a bare 'platform' string. The description mentions no parameter at all; the only parameter-adjacent text is 'Fields: soclo://tools/soclo_ads_get_ads_activity_log', which is a dead pointer rather than semantics, leaving the coverage gap entirely uncompensated.

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 identifies the resource as an 'Ad account change / audit log' for Soclo Ads, which is consistent with the tool name get_ads_activity_log. However, it neither states a verb of its own nor distinguishes this from nearby siblings such as soclo_ads_get_ads_timeline, soclo_ads_operation_status, or soclo_ads_get_ad_analytics, so an agent has to guess which read surface to pick.

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?

'Read only; no spend' signals a safe, non-spending read, but there is no statement of when to use this versus alternative audit/history tools, and no prerequisites (e.g. a connected ad account) or exclusions. Usage must be inferred entirely from the name.

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