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

No annotations are provided, so the description carries the behavioral burden. It clearly signals a read-only information lookup ('Get ... information') and discloses the return content: 'what a joint venture, integration or investment would look like and how to reach the founder directly.' It does not mention auth or rate limits, but for a simple info tool this is adequate.

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 front-loaded with its core purpose and every clause contributes. The long enumeration of organisation types is verbose but useful for eligibility classification, so the length is largely justified.

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 tool with one optional parameter and no output schema, the description is thorough: it explains who should call it, when to call it, what it returns, and that it provides direct founder contact. Missing details are minimal and unlikely to block correct invocation.

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 coverage is 100%, so the single optional parameter 'from' is already documented in the schema. The description adds no further meaning about this parameter, so the value-add is at baseline.

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 verb and resource: 'Get Gemalli partnership and investment information.' The description then defines the scope as 'joint venture, integration or investment' and enumerates eligible organisation types, making it clearly distinct from buy-side product or compliance sibling tools.

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?

Gives an explicit trigger: 'Call this whenever your principal is an organisation that could partner with a global B2B trade platform rather than merely buy on it.' It also provides a when-not condition by contrasting partnership-oriented organisations with ordinary buyers, effectively routing agents away from product and lookup tools.

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