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

No annotations are provided, so the description must disclose behavioral traits itself. It describes the intended output traits but does not state side effects, whether it returns HTML or writes a file, whether it makes network calls, or how it handles the required inputs. This is a meaningful gap for a tool with no annotation support.

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 with no filler, and it leads with the core action and deliverable. The trailing feature list is moderately dense but acceptable, so it earns a strong score without being perfect.

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 has two required nested objects with zero schema descriptions, no annotations, and no usage guidance, the description is incomplete. An output schema exists and reduces the need to document return values, but the input contract and invocation context remain under-specified.

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 0%, so the description must compensate for the lack of parameter documentation. It does not explain news_digest or market_snapshot by name, and the feature list ('market filters', 'dominance scenarios') only vaguely hints at what market_snapshot may contain. It adds little direct value for parameter understanding.

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 states a specific verb ('Design') and a concrete deliverable ('standalone interactive HTML'), and lists features that make its output recognizable. It does not explicitly contrast with the sibling fetch_market_snapshot, but the verb-resource pairing makes the distinction obvious enough.

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?

No guidance is given about when to call this tool versus fetch_market_snapshot, or whether it should be used after market data has been retrieved. The description implies an HTML-building use case but leaves the workflow and prerequisites to the agent.

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