entain_cms_entries

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

The description adds valuable behavioral details beyond the annotations: it states 'Auth: none needed' and defines the exact return structure ({sys, total, skip, limit, items, includes}). Annotations already declare read-only and idempotent behavior, so the description does not need to repeat those. No contradiction.

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 and well-structured: one-line resource definition, a Returns section, an Example, and an Auth note. Every element adds value with no redundancy or wasted words.

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?

For a simple read-only query tool, the description covers essential context: what it does, return format, an example query, and auth requirements. Combined with annotations and full schema coverage, no critical information is missing. It does not mention pagination defaults or error behavior, but those are not essential for a basic filtered list.

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 coverage is 100%, with each parameter described as 'Contentful CDA' fields. The description adds a concrete example (content_type=promotions, limit=20) that illustrates usage but does not explain parameters beyond what the schema already provides. Baseline of 3 is appropriate.

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 identifies the resource as 'Contentful CMS entries' with specific content types (promotions, major-event nav) and access method (www CDN proxy). While it lacks an explicit verb like 'retrieve' or 'list', the naming and content make the purpose unambiguous. It differentiates from sibling tools by specifying Contentful CMS entries.

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 an example ('Active promotions') but no explicit guidance on when to use this tool versus alternatives like entain_featured_slider or entain_quicklinks_list. There is no mention of exclusions or conditions that would favor another tool.

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