Behavior2/5

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

With no annotations, the description must fully disclose behavior. It states the tool returns a plan but does not clarify if it is read-only, if it modifies data, or if it requires authentication. Safety profile is unclear for an unannotated tool. The lack of side-effect description is a significant gap.

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 consists of two short, direct sentences with no extraneous information. Every word serves a purpose, front-loading the key action and output. It is an exemplar of conciseness.

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

Completeness3/5

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

Given the absence of an output schema and the presence of sibling commit tools, the description is incomplete. It does not explain how the returned plan should be used or link to the commit step. The return format is vaguely described. While it covers the basic purpose, it leaves gaps for effective usage.

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 coverage is 100% because the single parameter 'params' has a description, but the tool description adds no extra meaning beyond 'Action parameters as a JSON object'. The baseline for high schema coverage is 3, as the description does not elaborate on expected keys or examples.

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

Purpose5/5

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

The description clearly states it prepares a bulk product update and returns a plan with affected count and sample diffs. The verb 'Prepare' and resource 'bulk product update' are specific, and the output is described. Although the name includes 'catalog' and sibling tools exist for other entities, the description's focus on 'product update' distinguishes it effectively.

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

Usage Guidelines2/5

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 such as catalog_commit_bulk_update or other prepare tools. There is no mention of prerequisites, ordering, or when not to use it. The context of sibling tools implies a workflow, but the description itself is silent on usage direction.

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