crompton_album_characters

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

No annotations are provided, so the description must carry the full burden. It details the output structure but does not disclose whether the tool is read-only, has side effects, or requires authentication. The lack of safety information reduces transparency.

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 well-structured and front-loaded with the tool's purpose. It contains detailed enumerations that are useful but slightly lengthy; every sentence serves a purpose without redundancy.

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, the description fully details what the tool returns: per-character stats including line count, time on mic, tracks, sonic signature, and delivery stats. This is comprehensive for a tool with no parameters, fulfilling the need for complete context.

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 tool has zero parameters, and the schema description coverage is 100% (vacuous). According to the rubric, baseline for 0 parameters is 4. The description adds no parameter information because none exist.

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 defines the tool as providing 'Album-wide character voice fingerprints' and lists specific metrics per character (e.g., line count, time on mic, sonic signature). It distinguishes itself by explicitly pairing with crompton_album_references, indicating a unique role among siblings.

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 explicitly states usage: 'Use to verify attribution against a segment's stats, or to describe a delivery relative to the character's norm.' It also mentions pairing with another tool for a full picture, providing clear context. However, it does not explicitly exclude alternative sibling tools.

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