C2.9/5.0
Behavior3/5

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

With no annotations provided, the description carries the behavioral disclosure burden. It adds a meaningful non-disruption guarantee, which is useful context beyond the tool name. However, 'safe' is vague and there is no mention of side effects, idempotence, permissions, or failure behavior.

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

Conciseness4/5

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

The description is a single concise sentence with no wasted words, and the most important behavioral aspect ('safe', 'without disrupting') is front-loaded. It is appropriately short, though it sacrifices useful parameter and usage detail.

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

Completeness2/5

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

For a tool with 5 parameters, no schema descriptions, no annotations, and no output schema, the description is incomplete. It fails to mention the platform constraint, the productId requirement, the metaDescription field, and guidance relative to sibling tools. An agent would need to infer too much before calling it correctly.

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

Parameters2/5

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

Schema description coverage is 0%, so the description must compensate by explaining parameters. It mentions 'meta titles and keywords', covering metaTitle and metaKeywords, but omits metaDescription, productId, and platform entirely. The description adds minimal value over the raw schema and does not clarify required fields or value formats.

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 clear action ('update') on a specific resource ('meta titles and keywords') and emphasizes a non-disruptive approach. It is immediately understandable what the tool does. However, it does not explicitly differentiate from the sibling tool ecommerce_seo_optimizer, which likely overlaps in purpose.

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?

There is no guidance on when to use this tool versus alternatives. The phrase 'safe update' and 'without disrupting live product layout' imply a preference, but no explicit when/when-not conditions or references to sibling tools are given. An agent cannot confidently choose this over ecommerce_seo_optimizer.

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