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

No annotations are provided, so the description carries the behavioral disclosure burden. It discloses the input length limit (Max 8000 chars), the output score range (0.0 to 1.0), result flags, verdict, and rationale, and signals via '[FREE]' that no payment is required. It does not explicitly state side effects, but the tool is clearly a non-destructive scoring operation.

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 concise and front-loads the purpose and output. The parenthetical 'AgentWorld invention 3857' is minor noise, and the marketing-style closing phrase adds motivational context but is not strictly necessary. Overall, most sentences earn their place.

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 simplicity — one required text parameter, no annotations, and an output schema present — the description is complete enough for an agent to select and invoke it correctly. It explains the domain, constraints, and result types. It could add authentication or data-handling notes, but these are not critical for a read-only scoring 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 description coverage is 0%, so the description must compensate for the bare 'text' parameter. It does so by specifying that the text should be natural-language supplier communication and by adding the 8000-character limit. This is sufficient for an agent to understand what to pass, though it could be more explicit about edge cases like empty or non-English text.

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 states a specific verb ('Scores'), a specific resource ('natural-language supplier communication'), and a clear measurable output (ambiguity score, flags, verdict, rationale). It is clearly distinct from all listed siblings, none of which perform ambiguity analysis on communication text.

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 phrase 'Catch best effort language before it becomes financial drift' gives clear context for when to use the tool: when assessing supplier communication for vague commitments. It does not explicitly name alternatives or exclusions, but no sibling tool offers a comparable capability, so no such routing is necessary.

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