dale_chall_score

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

No annotations are provided, so the description must cover behavioral traits. It only states the basic function without disclosing output format (score vs grade level), input requirements (plain text, length limits), or edge cases. The output schema may help, but the description itself adds little transparency.

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 extremely concise: two sentences for the purpose and one parameter listed. It is front-loaded and contains no superfluous information.

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 tool's low complexity (one param, output schema exists), the description is fairly complete. It states the purpose and input. Missing usage guidelines and behavioral depth are minor for this simple tool, but they prevent a perfect score.

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%, so the description must explain parameters. It adds 'text — Text to calculate Dale-Chall score for,' which clarifies the single parameter's purpose. However, it lacks details like maximum length, encoding, or content restrictions.

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 'Calculate Dale-Chall readability score for text.' The verb 'Calculate' and resource 'Dale-Chall readability score' are specific, and it distinguishes from sibling tools like 'fry_readability' or 'gunning_fog_score' by naming a unique metric.

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. The description does not mention scenarios, prerequisites, or when Dale-Chall is preferred over other readability scores.

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