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

With no annotations the description carries the full behavioral burden; it does usefully disclose the exact conversion_rate semantics (formula, 2-decimal rounding, 100 cap, null-vs-0 distinction) and a dated contract change, which is real value. However it says nothing about read-only nature, pagination, ordering, or result size, so it is only partially transparent.

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?

Purpose is front-loaded in the main clause, with the detailed metric rules correctly relegated to a parenthetical. It is dense but every clause (formula, cap, null semantics, contract date) carries information an agent would otherwise get wrong.

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 no output schema and no annotations, the description should explain the returned shape; it covers conversion_rate well but says nothing about visits/conversions format, the limit parameter, or pagination. Adequate for the headline metric but incomplete overall.

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?

There is one parameter (limit) at 0% schema description coverage, and the description never mentions it, so neither source explains its meaning, default, or range. The description does not compensate for the coverage gap.

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+resource ('Lista las páginas de aterrizaje') and names the metrics returned (visits, conversions, conversion rate), which cleanly separates it from create_landing/update_landing. It does not explicitly distinguish itself from the other list_* siblings, keeping it 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 when-to-use guidance, no mention of alternatives (e.g. get_form, list_launches), and no stated preconditions or exclusions. The agent must infer the usage context 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.
