shuffle

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

No annotations are provided; description states the tool shuffles a string but lacks details on randomness, determinism, or edge cases. It does not contradict annotations though.

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?

Extremely short at two words, which is concise but risks underspecification. No unnecessary content, but could benefit from more structure.

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?

Simple tool but lacks essential details: no output schema, no explanation of what 'shuffling' entails (e.g., character order randomization), and no error or edge-case handling. Minimal completion for a production tool.

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 has 100% coverage but the description adds no additional meaning beyond the parameter name 'string'. The example value 'sama' in the schema is present but not elaborated in the tool description.

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?

Description 'Shuffles string' clearly states the action and resource, but does not differentiate from the sibling tool 'shuffle_1', which likely performs the same operation.

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 like 'shuffle_1', nor any context about prerequisites or typical use cases.

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