intuit_controller_action

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

No annotations are provided, and the description only mentions authentication scope and argument format. It does not disclose whether the operation is idempotent, what side effects occur, required permissions, error behavior, or rate limits. The behavioral profile is severely underdocumented.

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 brief (3 sentences) and front-loaded with the name and routing path. However, it sacrifices essential domain information for brevity, making it under-specified. Every sentence earns its place but fails to convey core purpose.

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 lack of annotations and an output schema, the description is drastically incomplete. It omits what operations are possible, what a successful response looks like, and how to interpret errors. For a generic action tool, this is insufficient for an agent to use it reliably.

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 single parameter 'arguments' is described as 'JSON string of arguments for the connector operation', but no further details are given about its structure, allowed keys, or constraints. Schema coverage is 0%, so the description adds minimal value beyond the parameter name and type.

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 focuses on the routing mechanism ('Routes through /api/tools/invoke under your JWT, tenant, and company scope') and the arguments parameter, but does not explain what the controller_action does. The name implies a generic action, but the actual business purpose is unclear, leaving the agent unable to distinguish it from more specific 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?

No guidance is provided on when to use this tool versus the many sibling tools (e.g., specific QuickBooks, Xero, or Stripe actions). The description lacks context for selecting this generic action over dedicated tools, leading to potential misuse.

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