Approve a video

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

Annotations only supply readOnlyHint=false, and the description usefully adds that approval is the trigger for video production. It says nothing about reversibility, what happens if the item was already approved, or what state the caller must already be in. With no declared parameters, it is also silent on how the target script is identified.

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 sentences with the action front-loaded. The second sentence largely restates the first, adding emphasis rather than new information, which costs it a point but keeps the definition scannable.

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 no-parameter, no-output-schema mutation tool, the description covers the core effect but leaves gaps: how the target video is scoped, whether approval is idempotent or reversible, and what the caller gets back. Adequate but not complete for an approval gate.

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?

Zero declared parameters, so there is no schema-level parameter documentation to compensate for; baseline 4 applies. The lax additionalProperties:true isn't addressed, but the description has no real parameter surface to explain.

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 (approve) and resource (a video script / video), and the phrase 'so the video gets made' clarifies the gate role that separates it from siblings like check_video_status or revise_video_brief. Minor wobble between 'video' in the name and 'video script' in the description, but the intent is unambiguous.

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?

Implies the usage context ('Nothing is made until you approve') so an agent can infer this comes after script generation and before production. However, no sibling tool is named and no explicit when-not condition is given, so the agent must infer the sequencing itself.

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