create-viz-filter

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It only states that a filter is created, but does not mention side effects, idempotency, permissions, duplicate handling, or any other behavioral traits. This is a significant gap for a mutation tool.

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 action. However, it is so brief that it sacrifices valuable context. It is not overly verbose, but the extreme brevity limits its usefulness.

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 that this is a create tool with one arbitrary object parameter, no output schema, and no annotations, the description is grossly incomplete. It does not explain what a visualization filter is, define the structure of the filter object, mention return values, errors, or any operational context. The agent cannot invoke this tool correctly with current information.

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 schema has one required parameter 'filter' of type object with additionalProperties: {}, meaning it accepts any properties. Schema description coverage is 0%. The description does not explain what the filter object should contain, what fields are expected, or provide any structure. The agent is left without guidance on how to construct valid input.

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 'Create a new visualization filter' clearly states the action (create) and the resource (visualization filter). It is specific and distinguishes from sibling tools like update-viz-filter, delete-viz-filter, and get-viz-filter by using 'new' to indicate creation.

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 provides no guidance on when to use this tool versus alternatives. There is no mention of prerequisites, related tools, or exclusions. It merely labels the operation without helping the agent decide between this and sibling create tools like create-view or create-policy.

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