raw_set_envelope

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

Annotations are absent, so the description carries the full burden. It does disclose meaningful side-effect risk by stating that the action 'may open a dialog or change project state.' However, it remains vague about what state changes may occur, whether they are reversible, and what dialog would appear; the advice to inspect the command name first pushes responsibility back onto the agent.

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 brief and front-loaded with the core function. The 'SetEnvelope:' prefix is somewhat redundant with the tool name but serves as the Audacity command label, and the safety caveat is kept to a single compact sentence.

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?

Despite the low parameter count, key behavioral questions remain unanswered: what 'envelope value' refers to, what 'specified time' means when there are no arguments, and what project-state changes to expect. The instruction to inspect the command name first is a stopgap rather than actual operational context, and there is no output schema or annotation to fill the gap.

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?

With zero parameters and 100% schema coverage, the input schema already fully defines invocation. The description's 'no-argument' claim aligns with the empty schema, and no additional parameter documentation is necessary, so the baseline score of 4 applies.

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 opens with a clear verb-resource pair: 'Adjust the envelope value at a specified time,' and identifies the underlying Audacity action as 'SetEnvelope.' This is specific enough to separate it from the many raw_* siblings, though it does not explicitly contrast it with any one alternative.

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 when-to-use or when-not-to-use guidance, and no sibling alternative is mentioned. 'Inspect the command name first' is a generic caution rather than a usable usage rule, and the description does not explain under what selection or project state this action is appropriate.

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