get_filter_group

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

With no annotations, the description carries the full burden. It does not disclose any behavioral traits such as return format, error behavior (e.g., 404 if not found), permission requirements, or whether the operation is read-only. It merely paraphrases the tool name.

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, compact sentence with no wasted words. It is immediately clear and front-loaded. However, it is so brief that it misses opportunities to include helpful context or usage notes, though it earns high marks for conciseness.

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 (one parameter, no output schema, no annotations), but the description is still incomplete. It does not explain what a filter group is, what 'details' includes, whether the tool returns the full resource or a partial representation, or any relationship to sibling tools like list_filter_groups. The description is too thin for a meaningful API call.

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 input schema has one required parameter 'id' with 100% schema description coverage, so the schema already documents the parameter. The tool description adds the context that 'id' refers to a filter group, but does not provide additional semantic details beyond what the schema and tool name already imply. Baseline 3 is appropriate.

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 "Get filter group details" clearly states a get operation on a filter group resource. It distinguishes from list_filter_groups (which lists all) by implying a single resource lookup, but "details" is vague about the specific returned fields.

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?

No usage guidance is provided. The description does not mention when to use this tool versus alternatives like list_filter_groups or identify any prerequisites or context. The sentence simply restates the tool's purpose without exclusions or alternative tool references.

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