mod_set_params

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

Annotations already declare readOnlyHint=false and destructiveHint=true, so the write/destructive nature is covered. The description adds the batch aspect but does not explain overwrite behavior, whether object lists are affected, or what happens on failure. It does not contradict the annotations.

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 short bilingual sentences, action-first and free of filler. Every clause contributes meaning, and the description remains compact despite bilingual duplication.

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 tool is simple and annotations cover its destructive nature, but the description leaves out how params should actually be encoded and does not mention the optional objects/current-selection behavior except via schema. It is adequate for an agent that reads the schema carefully, but not fully self-contained.

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 100%, but the description's statement that 'params is a name->value object' conflicts with the schema's array-of-strings type and provides no formatting details. This ambiguity could lead an agent to call the tool incorrectly, and the description adds no useful parameter semantics beyond the schema.

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 ('Set') and the resource ('modifier'), and calls out that multiple parameters are handled at once. This distinguishes it from mod_set_param in scope, though it does not explicitly name or contrast with siblings.

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 phrase 'several parameters of a modifier at once' implies batch usage, but the description gives no explicit when-to-use guidance or alternatives. With mod_set_param and mod_get_params as siblings, an agent would need additional inference to know when this tool is preferred over mod_set_param.

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