qc_connect

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 does explain the authentication model, the reconfiguration path for changing companies, and the non-effect on other apps. However, it does not disclose what happens on repeated calls, whether a session is established, whether the tool is idempotent, or what kind of result the agent should expect.

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 concise, front-loaded with the core function, and every sentence earns its place: the action, the usage triggers, the key configuration constraint, the company-change workaround, and the non-impact on other applications. There is no redundant filler.

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 zero-parameter tool with no output schema and no annotations, the description provides a thorough operational picture: purpose, when to use, configuration constraints, and how to change the target company. The only meaningful gap is lack of clarification about how qc_connect relates to the qc_healthcheck sibling for connection verification.

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, so there is nothing for the description to add about parameter meaning. The description still adds value by explicitly stating that API keys are not accepted as parameters and are instead configured in the connector, which prevents an agent from inventing arguments.

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 states a specific action: connect the company to QualityControl using the configured API key. It is easy to distinguish from the general idea of the tool, though it does not explicitly differentiate itself from sibling tools such as qc_healthcheck, which may also relate to connection verification.

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 concrete when-to-use guidance: when the user wants to log in, verify the connection, or reconnect. It also provides useful exclusions, such as not accepting API keys and not affecting other applications, but it does not name alternative sibling tools or explicitly state which tool to use instead in related scenarios.

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