upstash_redis_del

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

No annotations provide safety cues. The description omits that deletion is irreversible, potential side effects, or required permissions. For a destructive operation, more disclosure is needed.

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 short sentence with no redundancy, but it is too minimal and lacks necessary context. It earns its place but fails to inform adequately.

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?

No output schema exists, yet the description does not mention what the tool returns (e.g., confirmation, count). It also lacks information on error conditions, making it incomplete for a database delete operation.

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 the description only mentions 'key' generically. It adds no meaning to the four parameters (api_key, email, db_id, key), leaving them entirely self-documenting via the schema.

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 a key'), resource ('a key'), and target ('Upstash Redis database'), which distinguishes it from siblings like get and set operations.

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 versus alternatives (e.g., set, incr), no context on prerequisites or when not to use it.

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