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

No annotations are provided, so the description carries the full behavioral burden. It mentions 'No setup, works in any LLM chatbot', but never explains whether the tool runs an analysis, returns a static prompt/playbook, requires data from elsewhere, or what the optional query does. For a tool with no annotation coverage this is a significant disclosure gap.

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 short, but the opening sentence 'Save hours every week' is pure marketing and does not help tool selection. The remaining sentences are compact but front-load a claim rather than the tool's actual function.

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?

With no annotations and no output schema, the description should explain the diagnostic's purpose, expected output, and use of the query parameter. Instead it provides marketing copy and a vague promise, leaving an agent unable to determine what the tool will actually return.

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 optional parameter, and the schema already documents it at 100% coverage ('Optional user query to scope the analysis'). The description adds no additional meaning about how the query is interpreted or used, so the baseline 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 restates the name via 'repurchase diag tool toolkit' and adds marketing claims ('Save hours every week', 'battle-tested prompt'), but never states what the diagnostic actually does or what the agent gets back beyond a vague 'prompt and operating playbook'. It does not distinguish this tool from siblings like repurchase-analyze-tool or repurchase-formula-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 only contextual clue is 'for restaurant/brand growth', which implies a domain but gives no when-to-use guidance, no exclusions, and no comparison to the many repurchase-* alternatives. An agent has no basis for choosing this over repurchase-analyze-tool, repurchase-board-tool, or repurchase-tpl-tool.

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