stop_recording

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

Annotations already declare readOnlyHint=false, destructiveHint=false and openWorldHint=false, so the safety profile is covered. The description adds nothing behavioral beyond the verb: it doesn't say where the resulting file lands, whether the recording is finalized/saved, or how it behaves when nothing is recording — the key unknowns for a stop/commit action.

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?

A single front-loaded sentence with no filler, appropriately sized for a no-argument action. It is efficient but stops short of carrying any extra operational detail.

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 parameters, no output schema and annotations covering the safety profile, the definition is minimally sufficient to invoke the tool. However, an agent cannot tell from the definition whether stopping saves the file, where it goes, or what an error/no-active-recording case looks like.

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 tool takes zero parameters, which is the baseline 4 case; there is no argument semantics for the description 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 and resource ("Stop the current screen recording"), which cleanly separates it from siblings start_recording, start_recording_gif and is_recording by verb alone. It doesn't name those siblings explicitly, so differentiation is implicit rather than stated.

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 word "current" hints that a recording must be active, but there is no explicit when-to-use, no statement of what happens if no recording is running, and no reference to start_recording or is_recording as the pairing/verification tools.

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