feature_comparison_matrix

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 reveals nothing about side effects, whether the api_key parameter is actually required for an external call, what happens on failure, or what the generated output looks like. The bare verb 'Generate' gives no insight into the tool's behavior beyond the name itself.

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 efficient sentence with no filler, and the action verb is front-loaded. It is appropriately sized for the information it carries, though it invests those words only in restating the obvious mapping rather than adding behavioral value.

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?

With no annotations and no output schema, the description is the only source of context, yet it omits what the output artifact is (code in a chosen framework, HTML, markdown?), how the framework parameter changes behavior, and what the api_key is used for. For a 4-parameter tool, this is under-specified and leaves an agent guessing about invocation requirements.

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 75%: plans, categories, and api_key each have descriptions, while framework only has an enum. The tool description adds a small semantic link by implying features ('capabilities') become matrix rows and plans become columns, but it does not compensate for the undocumented framework parameter or clarify api_key's role beyond the schema's one-liner.

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 names a specific verb ('Generate'), a concrete resource ('feature comparison matrix'), and the scope ('showing capabilities across plans'), so an agent understands what artifact this produces. However, it does not explicitly differentiate from nearby siblings like pricing_table_component or pricing_toggle, which operate in the same plans/pricing domain.

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 when-to-use guidance, no exclusions, and no mention of alternatives. Siblings such as pricing_table_component and gha_add_matrix could plausibly overlap with a 'feature comparison matrix,' yet the description gives an agent no criteria for choosing between them.

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