sympy_expand_trig

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

No annotations provided. Description describes only the action without detailing behaviors (e.g., what identities are applied, side effects). Fails to inform the agent about operational aspects.

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?

Very short description, but lacks structure or detail that would make it more useful. Could be improved with a brief example or additional context without harming conciseness.

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?

For a simple 1-param tool with no output schema, the description should at least explain the form of output or what 'expand' entails. It does not, making it incomplete for agent understanding.

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 100% for the single parameter 'expr'. Description adds no extra meaning beyond the schema's 'String trigonometric expression', so baseline score of 3 applies.

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 states 'Expand trigonometric expressions', which is a specific verb and resource. It distinguishes from siblings like sympy_trigsimp or sympy_simplify, but could be more explicit about the type of expansion.

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 vs alternatives like sympy_trigsimp or sympy_expand. Implicitly for expanding trig, but no exclusions or context.

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