create_connect_session

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

With no annotations provided, the description carries the full burden of behavioral disclosure. The description only states it creates a session token, without any mention of side effects, permissions, idempotency, return value, or error conditions. It does not disclose anything beyond the action itself.

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 short and concise in length, but it is under-specified rather than effectively concise. The single sentence merely repeats the tool name and provides no additional information. It is not well-structured because it lacks any front-loaded key details that could help an agent decide to use it.

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?

Given the tool's complexity (4 parameters, multiple sibling session tools, no annotations, no output schema), the description is completely inadequate. It provides essentially no information that would enable an agent to call it correctly or differentiate it from alternatives.

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 description coverage is 0%, so the description must compensate by explaining the parameters (tags, environment, allowed_integrations, integrations_config_defaults). It does not mention any of them. The agent has no idea what values are expected or what each parameter controls, making correct invocation very difficult.

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 'Create a Nango Connect session token' is a tautology that restates the tool name without adding any specificity. It does not explain what a Nango Connect session token is, what it is used for, or how it differs from sibling tools like create_standard_connect_session or create_reconnect_session. An agent would have no idea what this tool does beyond the literal words.

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 the many sibling session-related tools (create_standard_connect_session, create_reconnect_session, etc.). The description offers no context, prerequisites, or exclusions. The agent must rely solely on the name and schema, which is insufficient for making an informed choice.

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