A3.8/5.0

Behavior3/5

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

Annotations already declare readOnlyHint=true, destructiveHint=false, and openWorldHint=false, so safety behavior is covered. The description adds filtering context through the prefix/format sentence and example, but does not add much beyond that, such as pagination expectations or repository scoping caveats.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is two concise sentences, front-loads the core action, and uses the example efficiently. There is no redundant or wasted text.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

The tool has nine parameters but full schema coverage, an output schema, and read-only annotations, so the description does not need to explain all parameters or return values. It is nearly complete, though it would be stronger with an explicit note on when to use aws_codeartifact_versions instead.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so all nine parameters are already documented in the schema. The description mentions prefix and format filtering and gives an example involving domain, repository, npm format, and prefix, but it does not add significant meaning beyond the schema.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description states a specific verb and resource: list packages in a CodeArtifact repository, with optional prefix/format filters. It is clear enough to distinguish the operation generally, but it does not explicitly differentiate itself from the sibling aws_codeartifact_versions tool.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

It gives clear usage context: list packages in a repository and optionally filter by prefix or format, reinforced by a concrete example. It lacks explicit when-not guidance or an alternative such as aws_codeartifact_versions.

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