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

Annotations already declare non-read-only, destructive, idempotent, and open-world behavior, so the safety profile is covered. The description adds genuinely new context beyond structured fields: 'can spend existing transcription credits' (a cost side effect) and 'inspect returned alignment and warnings' (output contents to check), which the annotations do not convey.

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, front-loaded with the primary action and with no filler. The workflow pointer and cost warning each earn their place, though the phrasing is slightly telegraphic.

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?

Annotations carry the safety profile and an output schema exists, so return-value documentation is not needed. The description adds workflow position and a cost warning, but omits prerequisites (tracks must already be attached) and any indication of what happens if the set is incomplete, leaving a meaningful gap for a destructive mutation.

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% across three required parameters (workspaceId, idempotencyKey, recordingSetId), and the description explains none of them. The idempotencyKey in particular warrants a note about retry semantics, which is absent from both the schema and the description.

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 a downstream effect (queue analysis), which distinguishes it from siblings like recording_sets_track_attach and recording_sets_get. It does not explicitly name a sibling to route against, so it clears the bar for clear-but-undifferentiated rather than the top mark.

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 a workflow position (finalize before clipping), which is useful sequencing context. However, there is no explicit when-to-use vs. alternative guidance or stated prerequisites (e.g., tracks must first be attached), 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.
