random_shuffle_list

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

With no annotations provided, the description carries full burden for behavioral disclosure. It does not specify whether the input list is modified or a new list is returned, nor does it mention randomness properties or output format. The minimal phrasing leaves important behavioral traits ambiguous.

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 wasted words. However, it is borderline under-informative for the lack of context, slightly reducing the score from a perfect 5.

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 the lack of an output schema and annotations, the description should explain the return value and behavior more thoroughly. It does not confirm that a new shuffled array is returned, which is essential for an AI agent to use the tool correctly.

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 description coverage is 0% (empty parameters object), so the description must compensate. It only restates the parameter name ('list' as synonym for 'items') without adding meaning. No details about accepted item types, constraints, or the effect on the input array are given.

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 tool shuffles a list randomly, using a specific verb 'shuffle' and resource 'list'. It distinguishes itself from sibling tools like 'random_pick_from_list' which picks a single element rather than reordering the entire list.

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 provides no guidance on when to use this tool versus alternatives. Among many random utility siblings, there is no mention of when shuffling is appropriate or how it differs from random selection or other random operations.

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