finalize_media_upload

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

No annotations exist, so the description carries the full disclosure burden. 'Preview by default' adds real meaning by interpreting the execute=false default as a preview, but it stops there. The description fails to disclose whether finalizing is irreversible, what side effects occur when execute=true, or what the preview actually shows — a significant gap for a workflow-completing step.

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 phrases with zero filler, and the primary purpose is front-loaded before the behavioral note. It earns a strong score for efficiency, though the brevity trades away behavioral and parameter detail that the agent needs.

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 don't need to be explained, but the description is otherwise incomplete for a tool with 3 parameters and no annotation coverage. An agent has no way to know the upload sequence, what to pass in path/body_json, or the consequences of setting execute=true. A finalization step with no safety information needs more context than this.

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%, yet the description adds almost nothing about the parameters. 'Preview by default' is the only hint, and it loosely maps to the execute boolean. The required path and body_json arguments are entirely unexplained, leaving the agent to guess what the path points to and what the JSON body must contain.

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) applied to a specific resource (media upload workflow) scoped to image/video assets. The sibling set includes initialize_media_upload, so the initialize/finalize contrast is visible even though it isn't named explicitly. The main gap is that 'finalize' itself isn't concretely explained, but the purpose is clear enough to separate this from its siblings.

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?

No guidance about when to call this tool versus alternatives. It doesn't say to use it after initialize_media_upload, mention prerequisites, or describe when preview mode is appropriate versus actually executing. The only hint, 'Preview by default,' describes an execution mode rather than routing an agent between tools.

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