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

Annotations already declare readOnlyHint/idempotentHint/destructiveHint=false, so the safety profile is covered. Beyond that, the description usefully discloses the return surface (player link plus a variable set of export formats), which annotations do not convey; it stops short of saying whether URLs expire, require permissions, or whether all formats are always present.

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?

It is a single front-loaded sentence with no filler, and the verb and primary resource come first. The long parenthetical format list is dense but informative and earns its space given there is no output schema.

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?

Since no output schema exists, the description must carry the return-value burden, and it does so by enumerating the artifacts returned. The remaining gap is behavioral detail about URL validity/expiry and whether the format set is conditional, which matters for an export-links 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?

With a single required parameter at 100% schema coverage, the schema already explains file_id as the unique transcription identifier, so the baseline is 3. The description adds only the phrase "pour un dossier" (folder), which arguably blurs rather than sharpens the meaning of a transcription file_id.

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 opens with a specific verb ("Retourne") and two concrete resources: the Studio interactive player link and the available export URLs, then enumerates the formats (.docx, .pdf, .srt/.vtt, .txt, IRaMuTeQ corpus). This makes it clearly distinguishable from siblings like get_transcription_text or get_transcription_summary, which return content rather than links.

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?

Usage is only implied: an agent can infer it should call this when it needs download/export links for a transcript folder, but there is no explicit when-to-use, no prerequisites, and no named alternative (e.g., use get_transcription_text to read the content instead). The guidance is adequate but leaves routing decisions to inference.

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