get_phonemes

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

No annotations are provided, so the description carries the full burden. It discloses one behavioral trait: 'returns empty string if none set'. However, it does not mention error behavior, whether it has side effects (it is a get, but that is not stated), or the shape of the return value for multiple notes. The disclosure is minimal.

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 with no redundant words. It front-loads the action and includes the key behavioral note about returning an empty string. Every part earns its place.

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 no output schema, no annotations, and three parameters with limited schema descriptions, the description is not fully complete. It mentions returning an empty string if none set, which is useful, but it does not explain the return format for multiple notes, how trackIndex and groupIndex combine, or any prerequisites. While adequate for a simple getter, it leaves some ambiguity.

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 only 33% (only noteIndex has a description). The description adds meaning by explaining that noteIndex is optional and selects a specific note, while groupIndex is used for groups. However, trackIndex is not mentioned at all, and the interaction between the indexes is not clarified. It partially compensates for the low schema coverage but leaves a gap.

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 (get), resource (user-specified phonemes), and scope (a group or a specific noteIndex). It distinguishes from get_computed_phonemes by saying 'user-specified', and from set_phonemes by being a getter. However, it does not explicitly name sibling tools, so it stops short of the highest level of 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?

The description implies when to use it via the phrase 'user-specified', which contrasts with computed phonemes, but it does not explicitly state conditions or alternatives. There is no statement like 'use get_computed_phonemes for reformatted phonemes'. The guidance is implicit rather than explicit.

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