Codec By Indexer

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

No annotations are provided, and the description does not disclose any behavioral traits such as side effects, rate limits, or request effects. The description is insufficient to inform the agent about tool behavior.

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, which is concise but severely under-specified. It does not earn its place as it lacks key details, making it more of a placeholder than a helpful 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?

Given the tool complexity (11 parameters, no schema descriptions, no output schema), the description is completely inadequate for an agent to correctly use the tool. It provides no context on return values, pagination, or parameter roles.

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%, and the description does not mention or clarify any parameters. With 11 parameters, the description fails to add meaning beyond the schema, leaving the agent with no guidance on parameter usage.

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 'Group history codec hints by indexer when available' indicates the tool groups codec hints by indexer, but it is vague about what 'history codec hints' are and does not differentiate from siblings like 'codec_distribution' or 'language_by_indexer'. It provides a general sense but lacks specificity.

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 guidance on when to use this tool versus alternatives. With many similar sibling tools (e.g., 'codec_distribution', 'quality_by_indexer'), the description offers no context for selection.

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