generate_phoneme_activity

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 merely says 'Generate' without revealing output format, side effects, required permissions, or whether the operation is read-only or mutating. This leaves agent decision-making under-informed.

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, front-loaded sentence with no filler or redundant information. It is brief and immediately conveys the tool's core purpose, earning every word's place in the description.

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 or annotations, the description should explain what the generated 'activity' looks like or how it is returned, but it does not. The parameter schema is complete, yet the overall tool behavior remains under-specified, especially given the existence of overlapping sibling tools.

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 already documents both parameters ('phoneme' and 'modalities' with a clear enum) at 100% coverage. The description adds no extra parameter semantics beyond using the word 'multisensory', which loosely maps to the modalities array but does not enhance the schema's meaning.

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 ('Generate') and resource ('phoneme practice activity'), clearly indicating what the tool produces. However, it does not distinguish this from the sibling tool 'generate_engagement_activity', which also generates an activity, so it lacks sibling differentiation.

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 use this tool versus alternatives like 'generate_engagement_activity', nor any mention of prerequisites, exclusions, or specific contexts. The description only states what it does, not when it should be chosen.

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