drop_key

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. 'Delete a key' implies destructiveness, but the description does not warn about irreversibility, required permissions, behavior for non-existent keys, or side effects (e.g., TTL cleanup). 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, focused sentence that front-loads the verb and resource. There is no wasted wording or redundancy. It is appropriately minimal for a one-parameter tool.

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), and the description gives a basic understanding of the operation. However, without annotations or output schema, the agent lacks information about return values, error handling, or idempotency. This is the minimum viable level but leaves clear gaps.

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 already provides a 100% description for the 'key' parameter, so the description adds no new meaning. The parameter is fully documented in the schema, meeting the baseline for high coverage without requiring extra detail.

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 (Delete) and the resource (a key in Redis), making the tool's purpose immediately obvious. However, it does not explicitly differentiate from sibling tools like delete_data or rename_key, so it doesn't fully meet the highest bar for sibling distinction.

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 gives no guidance on when to use this tool versus alternatives such as delete_data, rename_key, or set_data. There is no mention of prerequisites, exceptions, or situations where a different tool would be more appropriate, leaving the agent to infer usage solely from the name.

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