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

Annotations confirm this is a non-read-only, non-destructive, closed-world operation. The description adds real behavioral context beyond that: the tool performs an upload to Joydemo (a side effect) and produces a 'private editor link', which substitutes for the absent output schema. It does not say whether the operation blocks until upload completes or is idempotent.

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 sentence, front-loaded with the core action and then the two outcomes. Nothing is padded and every clause carries information.

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 one-parameter tool with no output schema, the description covers the action, the upload side effect, and the return value, which is what an agent most needs. It remains thin on the job_id contract and failure behavior, but the core call path is clear.

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 required parameter job_id has 0% schema description coverage and the description never mentions it, its expected format, or where it originates (presumably start_demo). With low coverage the description is expected to compensate, and it does not.

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 ('Finish a demo') and goes further by naming the two side effects: uploading the recording and returning the private editor link. This clearly separates it from start_demo and cancel_demo, though those siblings are not named 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?

The verb 'finish' implies this is the terminal step of a demo session, so usage is inferable from the lifecycle. However, there is no explicit statement of prerequisites (a demo must already be running), no mention of what happens if the demo does not exist, and no routing to alternatives like cancel_demo.

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