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

No annotations exist, so description bears full burden. It describes the action (add) and mentions return values (new pad index and MIDI note). However, it lacks details on side effects, error states, or prerequisites (e.g., if a pad with the same MIDI note exists). Adequate but not comprehensive.

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?

Two short sentences plus bulleted parameter descriptions. Every sentence provides value, no fluff. Front-loaded with purpose.

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?

Has output schema (mentioned but not provided), and description notes return values. Covers purpose and all parameters. Lacks error handling or overwrite behavior, but for a simple creation tool this is sufficient.

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 has 0% description coverage, so description must add meaning. It does so effectively: explains midi_note with examples (36=C1), sample_name, duration_seconds, and unit_index with auto-detect hint. Greatly enhances schema.

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?

Description clearly states 'Add a drum pad to a Playfield drum machine.' This specific verb-resource combination distinguishes it from sibling tools like copy_playfield_sample, list_playfield_samples, and set_playfield_sample_enabled.

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 explicit guidance on when to use this tool versus alternatives (e.g., copy or modify). Agent must infer from the verb 'Add' that it creates a new pad, but no when-not-to-use or contrasting conditions are provided.

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