speechify_upload_text_files

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

No annotations exist, so the description carries the entire behavioral burden, yet it omits critical traits: whether paths are resolved on the client or server, whether processing is asynchronous and how to poll, what happens on partial failure, and how idempotency_key affects re-submission. 'Persistent serial upload job' hints at queued sequencing but does not explain it.

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, so it is not bloated. But the brevity comes at the cost of under-specification rather than economy, so it does not earn a high score.

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 batch job-creating tool with four parameters, no annotations, and no output schema, the definition leaves too much unsaid: the return value (presumably a job id) and the follow-up call to check status are never referenced, and conflict/idempotency behavior is undocumented.

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 0% schema description coverage, the description must compensate, and it only partially does: 'absolute UTF-8 TXT paths' usefully constrains files[].path to absolute UTF-8 text files. Nothing is said about folder_id, the on_conflict enum (error / skip_identical / rename), or the required idempotency_key, all of which remain opaque.

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 names a concrete resource (UTF-8 TXT files identified by absolute paths) and the outcome (they are staged into an upload job), which separates it reasonably from the singular speechify_upload_text. However, 'prepare ... into a persistent serial upload job' is ambiguous about whether anything is actually transmitted or merely queued, and the word 'prepare' is a weak verb for what is likely a job-creation/upload trigger.

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?

There is no guidance on when to choose this over speechify_upload_text (single file) or how it relates to speechify_get_job / speechify_session_status for tracking the resulting job. An agent must infer the batch-vs-single distinction purely from the plural name.

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