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

The description goes beyond the annotations by disclosing the cascade: corner pin, camera push and the handed-off clip are all removed together, and it offers keep_clip as the mitigation for the clip loss. That is meaningful context an agent would not infer from destructiveHint=false / idempotentHint=true. It does not say whether removal is undoable or whether the underlying source media is preserved, so the destructiveHint=false claim remains partially unverified against a delete-style tool.

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 sentences with zero filler: the removal and its side effects come first, the optional escape hatch second. Nothing is redundant with the title or the annotations.

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?

With no output schema and only three parameters, the description covers the action and the clip trade-off adequately. However, for a mutation tool whose id parameter is undocumented in both schema and description, it should say where the id comes from and whether the removal is reversible — gaps an agent would hit on first invocation.

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 coverage is only 33% — project_id is documented, but id and keep_clip are bare in the schema. The description partially compensates by explaining keep_clip's effect ("retains the clip as a plain insert"), but 'an identified screen takeover' gives no clue how the id is obtained or formatted, and the keep-clip naming in prose does not match the keep_clip parameter name.

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?

The description uses a specific verb and resource ("Removes an identified screen takeover") and enumerates the owned components that go with it (corner pin, camera push, handed-off clip), so the agent knows exactly which object this targets. It stops short of naming the counterpart tools it is easily confused with, such as remove_screen_frame or remove_motion_graphic, so the distinction rests entirely on the resource name.

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 optional keep-clip setting retains the clip as a plain insert" implicitly conveys the decision point between full removal and downgrade-to-insert. There is no explicit when-to-use or when-not guidance, no statement of prerequisites (e.g., the takeover must exist in the current project), and no routing to the sibling removal tools.

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