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

The description meaningfully adds the ephemeral one-hour expiry and bearer-URL behavior, which is not present in the annotations. Since annotations only contain false hints, the description carries the behavioral burden; it does so for the most important lifecycle trait, though it omits other possible side effects or prerequisites.

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 with no wasted words. It front-loads the core purpose and then presents the key expiration behavior, making it easy to parse quickly.

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?

Despite having an output schema, the description is incomplete for a tool with 10 parameters and several non-obvious confirmation flags. Important context is missing: how to provide user-supplied data, what the required rights_confirmed and retention_confirmed flags mean, and how this tool relates to sibling snapshot and plotting tools.

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%, and the description does not explain any of the 10 parameters. Ambiguous fields like rate, rights_confirmed, retention_confirmed, and source_text are left entirely undefined, so the agent cannot infer how to populate the parameters correctly.

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 states a specific action ('Create a private interactive dashboard') and a distinct resource ('user-supplied data'). It is more informative than a tautology and hints at differentiation from snapshot/plot siblings, but it never explicitly names or contrasts an alternative tool.

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 no guidance on when to choose this tool over options like option_import_snapshot, option_plots, or option_strategy_plot. The phrase 'from user-supplied data' implies some context, but there is no explicit when-to-use or when-not-to-use guidance.

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