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

No annotations are provided, so the description carries the full burden. It discloses that entries are 'dated and concise' and that they are selected by AskCyborg's analyst panel as 'decision-relevant.' This adds meaningful context beyond the schema, explaining the curation process and return format. It does not mention potential limitations like pagination or recency windows, but for a simple retrieval tool, the transparency is strong.

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 three sentences, each earning its place. It front-loads the main purpose with the verb 'Retrieve,' then provides essential detail on entry format, and finally gives usage scenarios. There is no wasted text, and the structure aids quick comprehension.

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 only one parameter, no output schema, and no annotations, the description is largely sufficient. It explains what the tool returns (material developments, dated and concise), the types of developments included, and the curation context. It lacks an explicit statement that the result is a list or any limits on the number of entries, but these are implicitly inferable from the wording. For a tool of this simplicity, the description is complete enough.

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 covers the only parameter 'company' with a clear description: 'Company name, ticker, or slug.' Since schema coverage is 100%, the baseline is 3. The tool description does not add any additional information about the parameter beyond what the schema provides, so it neither improves nor worsens the score.

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 starts with a specific verb 'Retrieve' and clearly identifies the resource: 'most recent material developments' with enumerated types. It distinguishes itself from sibling tools like get_company_report or get_top_insights by focusing specifically on recent developments, making the tool's unique purpose obvious.

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 provides explicit use cases: 'news catch-up before a meeting, for monitoring portfolio companies, or to spot recent strategic shifts.' It does not explicitly mention alternatives or when not to use, but the contexts are clear and distinct from sibling tools, so it meets the bar for clear usage guidance without exclusions.

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