GetStoreReportByChannel

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

No annotations are provided, so the description must bear full weight. It only says 'Get the report by channel' without disclosing if it's read-only, any pagination, filtering, impact on data, or return format. This is insufficient for safe invocation.

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 short sentence, which is concise but sacrifices informativeness. It is appropriately sized for a simple tool but lacks crucial details, making it less useful.

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 complexity of the sibling group (many similar report tools) and the single body parameter without output schema, the description is incomplete. It does not explain the body's fields, the report scope, or how the output is structured, leaving a lot of ambiguity.

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?

The schema has one parameter 'body' with description 'Request body', which is generic. The tool description adds no extra meaning about the body's structure, required fields, or expected format. Despite 100% schema coverage, the schema description is minimal, and the tool description fails to compensate.

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 the verb 'Get' and resource 'report by channel', so it's clear what it does at a high level. However, among siblings like GetStoreReportByCategory and GetStoreReportByDay, it does not distinguish what makes a 'channel' report unique, leaving the purpose vague.

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 on when to use this tool versus alternatives. With many similar report tools (by category, day, product), the description should indicate scenarios or prerequisites. It provides none.

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