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

With no annotations provided, the description carries the full burden of behavioral disclosure. 'V1 Track History' reveals nothing about side effects, data access, idempotency, or any behavioral traits, leaving the agent completely blind.

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?

Although extremely short, this is under-specification rather than conciseness. The few words carry no functional information, and the version label 'V1' adds no value for tool selection or invocation.

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 a simple schema but complete absence of annotations, output schema, and meaningful description, the definition is inadequate for an agent to correctly invoke the tool. Even the tool name alone offers more inferable context than the entire description.

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 adds no meaning to the two string parameters 'url' and 'type'. The description must compensate for the undocumented schema but instead provides zero parameter context.

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 'V1 Track History' merely restates the tool name with a version prefix, providing no verb, resource, or outcome. It fails to explain what the tool does or how it differs from sibling tools like diff, price_track, track_check, and track_register.

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?

There is no guidance on when to use this tool versus alternatives. The description offers no context about typical use cases, prerequisites, or why an agent would choose track_history over its siblings.

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