mirelo_text_to_sfx_preflight

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

With no annotations, the description carries full burden. It clearly states the tool does not generate audio, which is a key behavioral trait. However, it does not disclose other behaviors like idempotency or quota effects, but for a preflight tool, the main behavior (estimation without side effects) is adequately communicated.

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 concise sentence that front-loads the key action and result. No unnecessary words.

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 no output schema, the description should at least hint at the return value (e.g., credit cost, processing time). It only says 'estimate' without specifying what the estimate includes. This is a notable gap for a preflight 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?

The input schema covers 100% of parameters with descriptions, so the description does not need to add much. It does not provide additional context beyond the schema. Baseline 3 is appropriate.

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 'Estimate the credit cost and processing time for a Text-to-SFX generation without generating audio'. The verb 'estimate' and resource 'Text-to-SFX' are specific, and the phrase 'without generating audio' distinguishes it from the generation sibling tools like mirelo_text_to_sfx_generate.

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 implies usage for cost estimation before generation, but it does not explicitly state when to use or not use this tool, nor does it mention alternatives. The name and sibling context provide some guidance, but the description lacks explicit usage directives.

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