arm_track_envelope

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It states the state change but not whether the track must be armed first, whether arming affects existing automation data, whether the change is reversible, or what confirmation is returned.

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?

The output is short and front-loaded with the action, and the Args block is compact. The redundant restatement of envelope_name is the only waste.

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 3-parameter mutation with no annotations and no output schema, the definition covers the core action and the arm flag's polarity but leaves the required track_index undocumented and omits any prerequisites or side effects.

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 0%, so the description is the only documentation. It usefully clarifies that arm=True arms and arm=False disarms (valuable given the default of true), but 'envelope_name: Envelope name' is a pure tautology and track_index is never mentioned despite being required.

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 states a specific verb pair ('Arm or disarm') and resource ('envelope for recording'), so the operation is unambiguous. It does not explicitly distinguish itself from the sibling arm_track, though the 'envelope' qualifier implicitly separates them.

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?

There is no guidance on when to arm versus disarm, what state the track or envelope must be in, or how this relates to the sibling arm_track tool. The agent must infer usage entirely from the verb.

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