insert_envelope_point

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

No annotations are provided, so the description must convey behavioral traits. It only states the core function without disclosing side effects, error conditions, or implications (e.g., whether it overrides existing points or requires specific permissions).

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 description is a single sentence, making it concise. However, it is arguably too short given the tool's complexity, and more detail could be included without losing conciseness. It is adequately structured but minimal.

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?

Given the tool has 7 required parameters, no output schema, and no annotations, the description is severely incomplete. It fails to explain parameter roles, usage context, or expected results, making it insufficient for reliable agent 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?

The input schema has 7 required parameters with 0% description coverage. The tool description adds no meaning to any parameter; it does not explain what 'time', 'value', 'parameter', or indices represent, leaving the agent to infer entirely from names.

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 clearly states the action ('insert'), the object ('single automation breakpoint'), and the context ('for a device parameter within a clip'). It distinguishes from the sibling tool 'insert_envelope_points' (plural) by emphasizing 'single', making it unambiguous.

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?

No guidance is provided on when to use this tool versus alternatives, such as 'insert_envelope_points'. The description lacks any when-to-use or when-not-to-use context, leaving the agent without decision-making support.

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