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

Adds real value beyond the annotations: it discloses a cost side effect ("Can spend existing transcription credits") and that analysis is queued rather than immediate, plus that alignment results and warnings come back and should be inspected. Annotations cover idempotency and destructive scope but not the credit spend or async queueing.

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?

Three short sentences, each earning its place: purpose first, then the cost disclosure, then the post-call inspection step. No filler or redundancy.

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-value detail is not required, and the description still flags the meaningful return elements (alignment, warnings). Purpose, cost, and workflow position are covered; the main gap is parameter-level meaning, which is left entirely to the schema.

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 0% and the description explains none of the three parameters (workspaceId, idempotencyKey, recordingSetId). The idempotency marker is implied by idempotentHint, but the description does not compensate for the total lack of parameter documentation as it should at this coverage level.

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 (finalize) and resource (collected camera and screen tracks) plus the downstream effect (queue analysis). Clear enough to distinguish from reads like recording_sets_get or attachment like recording_sets_track_attach, though it never names a sibling explicitly.

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?

"Inspect returned alignment and warnings before clipping" implies this is a step in a workflow that precedes clipping, giving some context for use. There is no explicit when-not guidance, no prerequisites, and no named alternative, so usage is only implied.

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