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

The description adds useful behavioral context beyond the annotations: credentials are sealed to the account and never shown again. However, it does not explain openWorld implications, reconnect behavior, what happens to existing credentials, or how disconnect-mode interactions work.

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 a single front-loaded sentence with no wasted words. It is efficient, but its one-sentence structure is very sparse for a tool with nine parameters and openWorld behavior.

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 complex, open-world credential-storage operation with nine undocumented parameters, the definition is far from complete. Annotations provide some safety context and the description covers secrecy, but usage guidance and parameter behavior are largely absent.

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?

With 0% schema description coverage across nine parameters, the description offers only minimal semantic help by naming connector and credentials. It leaves code, state, redirect_uri, sandbox, settings, vars, and disconnect completely unexplained.

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 specific verb and resource: storing credentials for a connector. It adds a clear scope constraint (account-only, never shown again), but it does not explicitly differentiate this from sibling tools such as integration_grant or integration_call.

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 alternatives, nor any prerequisites or exclusion conditions. The sentence implies credential storage but gives no routing context among the many integration-related siblings.

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