calculate_tiktok_rpm

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

No annotations are provided, so the description carries the full burden. It describes the outputs (RPM range, per-video estimate, monthly projection) but does not explicitly state that it is a safe, read-only operation or disclose any side effects. The behavior is implied as a calculator, but more explicit transparency would improve the score.

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 two sentences with no unnecessary words. It front-loads the main purpose and output, then adds a single detail about the data source. 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?

Given the complexity (4 parameters, no output schema), the description covers the main purpose, inputs, and outputs. It lacks detail on the exact format of the returned values (e.g., whether RPM range is a string or structured object), but it is still generally complete for a straightforward estimation tool.

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 coverage is 100% with each parameter having a description. The description adds context about the output and that 'videosPerMonth' is optional for monthly projection, but does not significantly enhance parameter understanding beyond the schema. Baseline 3 is appropriate.

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 clearly states the tool estimates TikTok Creator Rewards revenue, specifying the verb 'estimate' and the resource (revenue for a given niche, audience country, and view count). It distinguishes itself from sibling tools like calculate_tiktok_engagement_rate by focusing on revenue estimation.

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 provides clear context on usage (estimating RPM for a niche, country, and view count) but does not explicitly state when not to use it or contrast with alternatives. However, given the niche focus, it is adequately clear.

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