recording_stop

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

No annotations are provided, so the description carries the behavioral disclosure burden. It does state the key side effect: it stops recording and builds PDF evidence from captured slides. It does not, however, disclose what happens if no recording is active, whether the session is also stopped, or whether the operation is idempotent.

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. It states the primary action first and the resulting artifact second, making it easy to scan.

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?

The tool is simple, has only one optional parameter, and an output schema exists, so the description is mostly sufficient. The main gaps are the lack of any session_id semantics and the absence of guidance on prerequisites or failure behavior, but these are minor for a simple stop operation.

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%, and the description does not mention session_id at all. The schema provides the parameter name, title, and a default, but the description adds no meaning about which session to stop or when the parameter matters.

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: 'Stop recording' and 'build PDF evidence from captured slides.' It clearly distinguishes itself from siblings like recording_start and recording_capture, which are about beginning or capturing rather than finalizing.

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 phrase 'Stop recording' implies this tool is used after recording has begun, and its role as the counterpart to recording_start is reasonably clear. However, it does not explicitly state when to use it versus alternatives, nor does it mention any prerequisite like an active recording session.

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