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

Annotations already declare readOnlyHint=true and openWorldHint=false, so the safety profile is covered. The description usefully adds the data source (bina.et/watch) and enumerates returned fields, but says nothing about pagination, result caps, or freshness of 'newest episodes'.

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?

Two sentences, zero filler, with the resource scope and returned payload front-loaded before the input hint. Every clause earns its place.

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?

For a one-optional-parameter read tool with full schema coverage and an output schema, the description supplies enough to invoke it correctly. The only omission is routing against the near-identical sibling list_tv_and_radio.

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 description coverage is 100% and the schema example already shows both Latin and Amharic input ('Derash or ደራሽ'). The description's 'English or Amharic' note reinforces but does not extend the schema, so the baseline 3 applies.

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 resource (Ethiopian TV drama/comedy series on BinaWatch) plus the exact payload (channel, newest episodes with title/date/watch link), so an agent knows precisely what comes back. It does not, however, distinguish itself from the sibling list_tv_and_radio, leaving a real ambiguity unresolved.

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 says what can be searched (title, English or Amharic) but never states when to pick this tool over alternatives. With list_tv_and_radio sitting in the sibling set, the absence of any routing guidance is a meaningful gap.

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