press_button

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

No annotations exist, so the description carries the full burden of behavioral disclosure. It reveals only that the call returns the node's errors and warnings; it says nothing about side effects of pressing (cooking, file writes, renders), whether the action is reversible, required permissions, or what happens if the parameter is not a button. That is a thin profile for an operation that clearly mutates node state.

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?

A single front-loaded sentence with no filler, so nothing is wasted. However, at this brevity it is under-specified rather than concise: the space saved is space the agent needed for parameter and side-effect guidance.

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?

With five parameters, zero schema descriptions, no annotations, and no output schema, the definition leaves major gaps. It does at least state the return content (errors and warnings), partially compensating for the missing output schema, but the caller still lacks the information needed to set cook, action, and arguments correctly.

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% across five parameters, so the description must compensate and largely fails. It implicitly maps node_path ('the node's') and parm_name ('a button parameter'), but cook, action, and arguments are left entirely unexplained — an agent cannot tell whether cook=true triggers a cook or what keys 'arguments' should contain.

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?

Names a specific verb and resource ('Press a button parameter') plus the immediate outcome ('return the node's errors and warnings'), which is clearer than a bare restatement of the name. It does not explicitly contrast with any sibling, but no listed sibling appears to overlap, so the agent can identify the action. Minor deduction because 'button parameter' is domain jargon left undefined.

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 contains no when-to-use, when-not-to-use, or alternative routing. The mention of returning errors and warnings only weakly implies a verify-after-trigger workflow; nothing tells the agent when pressing a button is preferable to other node-activation tools such as cook_top_node or cook_frame_range.

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