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

The description discloses the replacement/upsert behavior, which is important for a write operation. However, it lacks details on side effects, required permissions, or whether the operation is idempotent. With no annotations, more behavioral context would be beneficial.

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 concise with two sentences, front-loading the main function. It is efficiently written but could benefit from structured details for parameters.

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?

Despite having an output schema, the tool lacks parameter descriptions and usage guidelines. This incompleteness forces the agent to guess parameter semantics, reducing its autonomous usability.

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 description does not explain the meaning or expected format of the 'key' and 'content' parameters. With 0% schema description coverage, the agent has no guidance on what values to supply, making correct invocation difficult.

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 states the action ('Index') and resource ('knowledge base article'), and specifies the key behavior of replacing existing articles with the same key, which distinguishes it from sibling tools like 'remove' and 'search'.

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. It does not mention prerequisites, when to avoid usage, or how it relates to the sibling tools beyond implied functionality.

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