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

Annotations already declare readOnlyHint=true, destructiveHint=false, idempotentHint=true, and openWorldHint=true. The description adds useful behavioral context by stating that no model run starts and no customer data changes, which goes slightly beyond the annotations. However, it does not describe error behavior, authorization needs, or what exactly is returned beyond the brief's contents.

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 two sentences, front-loads the core purpose, and has no wasted language. The safety clause is concise and supports the read-only framing without overwhelming the definition.

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 single-parameter read-only tool with rich annotations, the description is largely complete: it identifies the resource and summarizes the returned information (brief, draft article references, publication state). The main remaining gap is routing guidance versus sibling read tools, which keeps it from being fully complete.

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?

There is only one parameter, and the input schema has 100% description coverage ('Summer company ID'). The description does not add any meaning about the company identifier beyond what the schema already provides, so the baseline score of 3 applies.

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 uses a specific verb ('Read') and names the resource precisely: the company's reviewed guide-authoring brief, draft article references, and publication state. It is clear what the tool does, but it does not explicitly distinguish itself from related siblings such as summer_guides_get or summer_guides_articles_get.

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 offers no explicit guidance on when to use this tool versus alternatives, nor does it state any prerequisites or exclusions. The phrase 'This read starts no model run and changes no customer data' is safety context, not usage guidance, so an agent must infer when this read is appropriate.

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