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

With no annotations provided, the description carries the transparency burden. It discloses that the tool is server-rendered, structured by category, Palestine-desk led, and includes publish time/ages per item; it also indicates that the content should be relayed unmodified. It could add more about default, size, or limitations, but it gives meaningful behavioral context beyond the raw schema.

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 compact and front-loaded: the first sentence establishes the tool's output, the second lists output formats, and 'Relay as-is' adds a clear consumption hint. Every clause adds value, with no filler or repetition.

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 simple tool with two optional parameters and no output schema, the description covers the main behavioral, content, and formatting aspects well. It does not mention the per_section limit or explicitly distinguish from similar daily-brief sibling tools, but the core rubric arguably covers that gap.

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?

The schema describes only 50% of parameters, and the description enriches the format enum by specifying markdown for chat, html for a standalone page, and json for structured data. However, the per_section parameter is not addressed at all beyond its numeric bounds, so the agent has to infer its meaning from the 'per item' text and the parameter name.

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 identifies the tool as a server-rendered daily brief with categorized sections, item publish times, and age, so the core function is comprehensible. It is not explicitly phrased with a verb like 'retrieve' or 'get', and it does not contrast itself with closely related siblings such as asha_digest or asha_feed.

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 instructs when to choose markdown, html, or json output and says 'relay as-is,' which is useful for the format. However, it offers no guidance on when to use this daily-brief tool versus the many sibling tools (digest, breaking, feed, market context, etc.), so an agent may not know whether this is the appropriate tool for a given request.

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