verify_video

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

Annotations already declare readOnlyHint=false, idempotentHint=true, destructiveHint=false and openWorldHint=true; the description usefully adds that it reads remote data back and then writes to local records, explaining the read-write hybrid. It does not say what happens on a verification mismatch or whether a failure leaves local state untouched.

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?

One front-loaded sentence with no filler; the verification fields and the local update are packed in without waste. Slightly dense at the expense of readability but structurally sound.

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?

An output schema exists, so return values need not be explained, and annotations cover the safety profile. However, an idempotent mutating verification tool should clarify the job_id semantics and the outcome of a failed check; those gaps remain.

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 single parameter job_id has 0% schema description coverage and the description never mentions it, so the agent must guess what identifier it refers to (a prepared video job? a sent post?). It cannot compensate for the schema gap.

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 operation: read back the post, reconcile ID/sender/destination/encryption format/storage location, then update local records. The verb+resource is clear enough to act on, though it doesn't distinguish itself from siblings like get_status or prepare_video.

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 indication of when this tool should be chosen over alternatives such as get_status or prepare_video, nor any preconditions (e.g., the job must already be sent). Usage must be inferred entirely from the name.

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