Quality By Indexer

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

No annotations are present, so the description must disclose behavior. It does not mention whether the tool is read-only, what side effects exist, or any other operational traits beyond the vague 'group' action.

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?

While the description is a single sentence, it is underspecified for a tool with 11 parameters. Conciseness is not valuable when it omits critical information.

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 the complexity (11 parameters, no output schema) and existence of similar sibling tools, the description is severely incomplete. It does not explain return values, parameter usage, or how to differentiate from other 'by_indexer' 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?

Schema description coverage is 0%, so the description must explain parameters. It adds no meaning beyond the schema, leaving all 11 parameters undefined. The description fails to clarify required or optional parameters.

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 'Group history qualities by indexer,' which provides a verb and resource but is vague. It doesn't clarify what 'qualities' refers to, and among many 'by_indexer' sibling tools, it doesn't uniquely distinguish the tool's purpose.

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 usage context is provided. There is no guidance on when to use this tool versus alternatives like codec_by_indexer or grabs_by_indexer, nor any exclusions or prerequisites.

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