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

No annotations are provided, so the description carries full burden for behavioral disclosure. It mentions 'filtering options' but doesn't explain key behaviors: that this is a read-only operation (implied by 'list'), that it supports pagination (page/perPage), sorting (orderBy/sort), or search functionality. For a tool with 8 parameters and no annotation coverage, this leaves significant gaps in understanding how the tool behaves.

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, efficient sentence that gets straight to the point. It's appropriately sized for a list operation, though it could be slightly more informative without losing conciseness. The bracketed '[Packages Management]' prefix adds some context but isn't strictly necessary.

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's complexity (8 parameters, no output schema, no annotations), the description is insufficient. It doesn't explain what 'artifacts' are in this context, what the output looks like, or how pagination/search/sorting work together. For a list tool with rich filtering capabilities, more context is needed to help an agent use it effectively.

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 100%, meaning all parameters are documented in the schema itself. The description adds minimal value beyond the schema by mentioning 'filtering options' (which hints at search, orderBy, sort parameters) but doesn't provide additional context about parameter relationships or usage. This meets the baseline score when schema coverage is high.

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 ('List artifacts') and the resource ('in a package repository'), making the purpose understandable. It also mentions 'with filtering options' which adds specificity. However, it doesn't explicitly differentiate this tool from other list_* tools in the sibling set (like list_package_repositories or list_files), which prevents a perfect score.

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 provides no guidance on when to use this tool versus alternatives. It doesn't mention prerequisites (like needing to know organizationId, repoId, and repoType first), nor does it suggest when filtering is appropriate. The sibling tools include list_package_repositories, which might logically precede this tool, but no such relationship is indicated.

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