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

With no annotations provided, the description carries the burden of behavioral disclosure. It explicitly states that the tool uses GET (read-only), requires no API key or wallet, and returns specific content. This goes beyond a simple function name by providing access and resource details. It does not mention rate limits or error handling, but for a simple read operation this is adequate transparency.

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 long and front-loads the essential information: what the resource is, what it contains, the endpoint, and access requirements. Every word adds value, with no redundant or vague phrasing. It is highly concise while remaining informative.

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 parameterless GET endpoint, the description covers the main aspects: the resource, output items, and access conditions. It is largely complete. However, since there is no output schema, it could provide a little more detail on the sentiment format or possible empty responses, but this is a minor gap given the tool's simplicity.

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 tool has zero parameters and the schema is empty, so there are no parameter semantics to explain. The description adds no parameter-related information, which is appropriate. It instead describes the output, but this is not required for this dimension. The baseline for 0 parameters is 4, and the description does not detract from it.

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 retrieving the 'Current Master Intelligence digest brief' and specifies its contents: title, executive summary, and overall sentiment. It also includes the API endpoint, making the resource unambiguous. It does not explicitly contrast with sibling tools like get_intelligence_history or get_pulse_digests, so it misses the top score.

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 guidance on when to use this tool versus the sibling tools. While the word 'Current' implies it is for the latest brief, it does not state when to use alternatives for historical data or other intelligence types. The only usage condition ('FREE, no wallet or API key required') addresses prerequisites, not selection criteria.

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