add_set

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

No annotations provided; description is too brief to disclose any behavioral traits. Does not mention what happens if key doesn't exist (creates set), duplicate handling, or side effects.

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?

Under-specification: only 4 words, sacrificing clarity for brevity. Should include more context within a short space.

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 2 required parameters, no output schema, and no annotations, the description is completely inadequate. Lacks detail on behavior, constraints, and differentiation from siblings.

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 0% and description adds no meaning beyond parameter names. Does not explain that 'key' is the set key or that 'members' are the elements to add.

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 'Add members to a set' which indicates the verb and resource. It distinguishes from sibling 'add_sorted_set' implicitly, though not explicitly.

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 guidance on when to use this tool vs alternatives like add_sorted_set. Does not mention conditions or best practices.

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