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

The annotations already declare readOnlyHint and idempotentHint, so the safety profile is covered. The description adds meaningful context about the informational content returned and the intended first-step behavior. For a zero-parameter read-only tool, no further behavioral disclosure is necessary.

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 with no wasted words. It front-loads what the tool returns, then immediately gives usage positioning relative to more specific tools. Every sentence 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 no-parameter, read-only informational tool, the description is complete: it lists the output domains, explains when to call it, and the annotations cover side-effect safety. There is no output schema, but the natural-language content enumeration fills that gap adequately.

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 input schema has zero parameters, and the description correctly avoids inventing any. With no inputs to clarify, the baseline of 4 applies; the description adds no param-specific detail because none is needed.

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 states a clear resource (Upforge company overview) and enumerates the exact content categories: what they build, location, operating history, contact, and technologies. It also distinguishes the tool from its siblings by instructing the agent to call it first for general company questions.

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 gives strong when-to-use guidance: call this first for general 'who are they / what do they do / are they legitimate' questions. It implies not to use it for specific queries by saying to reach for 'a more specific tool,' but it does not name a concrete alternative sibling, so it stops just short of fully explicit routing.

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