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

Annotations already declare readOnlyHint=false, idempotentHint=false, and destructiveHint=false, so the safety profile is covered. The description adds genuinely useful context beyond that: data lands in the workspace and the call yields a transcript_id that feeds the audio pipeline. It stops short of noting the practical consequence of idempotentHint=false (re-uploads create a new transcript rather than replacing one).

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?

Two short sentences with zero filler; the purpose comes first and the downstream handoff second. Every clause carries information an agent needs, with no restatement of the title or 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?

With annotations, a fully described two-parameter schema, and an output schema covering the return value, the description only needs to explain role and chaining — which it does. Minor gap: it doesn't clarify workspace scoping or whether overwriting/duplicate handling exists, though the non-idempotent hint in annotations partially signals that.

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 100% — both `text` (max ~200k chars) and `title` (max 200 chars) are documented in the schema, including length limits. The description adds no additional parameter meaning beyond implying that `text` is a full transcript, so the baseline of 3 applies.

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?

States a specific verb and resource ("Store a transcript") plus the storage location ("in the workspace") and its role in the Grok Boost audio pipeline. It also names the downstream sibling grok_generate_audio, so an agent can place it precisely in the toolchain rather than confusing it with generic file tools like import_file.

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 makes the call sequence explicit: store the transcript, then pass the returned transcript_id to grok_generate_audio. That is clear positive guidance, but there are no exclusions or preconditions (e.g., when to use this versus import_file for raw files, or what happens if you re-upload the same transcript).

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