stopRecording

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

Annotations only declare readOnly=false, destructive=false, openWorld=false, so the description carries the interesting load and does so well: it explains that the take plus recorded clicks become one clip with planned zooms, that clicks merge into shared zooms, that early/stopping clicks get none, and that autoZooms controls the count. It stops short of stating preconditions (must a recording be active?) or side effects on the recording state afterward.

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?

Purpose is front-loaded in the first clause and every subsequent sentence carries real information about zoom planning or return values. It is somewhat dense and clause-heavy, which slightly impedes scanning, but there is no filler.

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, the description usefully enumerates the return values (projectId to edit, checkpointId restoring the raw take, videoPath). Combined with the zoom-planning detail, an agent has enough to call and interpret it, though error/precondition behavior is unaddressed.

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?

Only one parameter (title) and the schema already documents it at 100% coverage, so the baseline is 3. The description mentions the new project but never connects it to the title argument, adding no meaning beyond the schema.

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 recording and turn the take into a new project'), and the remainder of the sentence specifies the exact layout semantics of the produced project. This clearly separates it from startRecording and createProject in the sibling list.

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?

Usage is implied rather than stated: the reader infers this is for ending an in-progress recording. There is no explicit when-not condition (e.g. what happens if no recording is active) and no named alternative such as createProject when the user wants a project without a take.

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