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

Discloses key non-behavior (does not play content) but lacks other traits like error handling, idempotency, or side effects; no annotations to contradict.

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?

Well-structured with Args/Returns sections; front-loaded purpose followed by param details; no redundant filler though schema repetition could be trimmed.

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?

Adequate for basic invocation but omits error scenarios, parameter relationships (query vs title_id interdependency), and return value format details despite output schema existing.

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?

Compensates effectively for 0% schema coverage by documenting all 5 parameters, including platform values and Netflix-specific constraints for optional fields.

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 specific action (resolve to platform ID) and distinguishes from siblings via 'without playing' clause, though could explicitly name sibling tools it differs from.

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 implied guidance via 'without playing' but lacks explicit when-to-use vs alternatives (tv_play, tv_cast) or workflow integration guidance.

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