set_attr_path

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. It only states 'Set a value', implying mutation, but does not mention side effects, reversibility, permissions, or return values. This is minimal and insufficient for an agent to anticipate consequences.

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, concise sentence that is front-loaded with the core action. It avoids unnecessary verbosity, though it could have included brief parameter clarification without becoming lengthy.

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 simplicity (two parameters), the description is still incomplete: it does not explain the value parameter, potential errors, or what the output represents (despite an output schema being present). An agent would need additional context to call this reliably, especially given the absence of parameter details.

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 coverage is 0%, so the description must explain the parameters. It provides partial meaning for 'path' (a dotted path ending in an attribute name) but says nothing about 'value' – its type, format, or constraints. The description does not fully compensate for the lack of schema documentation.

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 the action: setting a value via a dotted path that ends in an attribute name. This specific verb+resource structure distinguishes it from the sibling get_attr_path and other setter tools, though it does not explicitly mention which object or attribute types it applies to.

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 such as get_attr_path or other setter tools. The description does not mention any prerequisites, conditions, or exclusions, leaving the agent to infer usage context.

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