rpop

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

Cannot rely on annotations (none provided). Description lacks details on list empty behavior, blocking semantics, or side effects. Only bare operation stated.

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?

Single short sentence with no filler. However, it may be excessively terse, sacrificing necessary context for brevity.

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?

Output schema exists but is not detailed in the description. Lack of parameter explanation and behavioral edge cases makes it incomplete for reliable agent use.

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?

Input schema has one parameter 'name' with 0% description coverage. Description does not explain what 'name' refers to (e.g., the Redis key for the list). No added meaning beyond 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?

Clearly states the tool removes and returns the last element from a Redis list, using a specific verb and resource. This distinguishes it from siblings like lpop (first element) and rpush (add to end).

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 rpop versus alternatives (e.g., lpop for first element, lrange for peeking). No mention of prerequisites or context.

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