Set config values

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

The description goes beyond the sparse annotations by disclosing atomic behavior, the return shape {applied, errors}, and that nothing is applied on any invalid key. This provides meaningful behavioral context that the annotations do not cover. No contradiction.

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?

Two sentences, front-loaded with the core action, and no redundant words. Every sentence contributes useful information about atomicity and error 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?

The description covers atomicity and return values, which are key for a config setter, but omits important context such as how to discover valid keys, whether the tool applies to session or persisted config, and when to prefer sibling tools like set_object_config. Given the simple one-param schema, this is a moderate gap.

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%, and the description does not compensate. The term 'config changes' vaguely implies the structure of the 'changes' object but offers no example, key format, or details on how valid keys are determined. The parameter name alone does not suffice.

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 ('Apply config changes') and resource ('config changes'), and the atomicity aspect distinguishes it from simple getters. However, it does not explicitly differentiate from set_object_config, relying on the sibling name to imply broader scope.

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 like set_object_config, set_layer_height, or find_config_keys. It simply describes the operation without contextualizing its applicability.

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