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

With no annotations, the description carries the full burden, and it never says what the tool actually returns or does — the closest clue is "battle-tested prompt and operating playbook," which hints the output is a prompt template but gives no format, length, or behavior detail. Phrases like "save hours every week" add no behavioral information.

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?

Three sentences, but the opening ("Save hours every week") is pure marketing filler and the middle sentence repeats the tool name rather than adding information. Only the final sentence carries any content, and it is front-loaded after the filler instead of leading.

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?

For a no-annotation, no-output-schema tool the description must explain what gets produced, and it does not beyond the vague "prompt and operating playbook." It also gives no indication of the actual domain, so an agent cannot reliably tell what artifact it will receive.

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 parameter is optional with its own description, so the baseline of 3 applies. The description adds nothing about how a scoping query changes the returned template, but it is not required to when the schema already documents the field.

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 largely restates the name ("This proto tpl tool toolkit") without stating a concrete verb or deliverable. The one substantive claim, "restaurant/brand growth," does not match the rd-proto prefix or its siblings (rd-proto-check-tool, rd-proto-gen-tool), which point to an R&D prototyping template, so the description actively misleads about the resource.

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 when-to-use guidance of any kind, no when-not-to-use, and no mention of the two obvious alternatives in the same family (rd-proto-check-tool and rd-proto-gen-tool). The only usage statement, "No setup, works in any LLM chatbot," is a marketing claim, not a routing rule.

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