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

With no annotations, the description carries the full disclosure burden, yet it only offers vague claims ('save hours every week', 'no setup'). It never says what invoking the tool actually produces — a prompt text, a checklist, a playbook dump — or whether it consumes the optional query.

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?

Only three sentences, but the lead sentence is pure sales copy ('Save hours every week') rather than the tool's function, and the second sentence contradicts the tool name. The space is spent on persuasion instead of information.

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?

The tool is simple (one optional parameter, no output schema, no annotations), so a short description could be complete — but this one never states what content the playbook covers or what the agent receives back. An agent cannot predict the result before calling it.

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 100% and the single 'query' parameter is documented as an optional scoping input, so the schema does the work. The description adds nothing about how a query shapes the output, which is the baseline 3 for a fully described schema.

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 calls it an 'online shopping rights toolkit' but then claims it is 'for restaurant/brand growth', so the actual purpose is self-contradictory. What remains is marketing framing ('battle-tested prompt and operating playbook') rather than a specific verb+resource an agent can act on.

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 select this tool, no conditions, no exclusions, and no mention of the hundreds of sibling tools it competes with. 'Works in any LLM chatbot' describes portability, not usage selection.

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