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

No annotations are supplied, so the description carries the full disclosure burden and does not meet it. It hints that the result is 'delivered as a copy-paste prompt pack with examples,' but does not clarify whether the tool returns analysis, a generated prompt, or template text, nor anything about side effects, limits, or prerequisites.

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 two sentences, but nearly every phrase is promotional filler ('production-ready,' 'repeatable,' 'you can run today'). The text is short yet still wastes its limited space on sales language rather than operational 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), but the description still leaves the essential question unanswered: what does the agent get back and what does it do with the query? For a definition with no annotations to lean on, this is incomplete.

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% for the single optional 'query' parameter, so the schema already defines it; the description adds no scoping or formatting guidance beyond it. With full schema coverage and no compensating detail, the baseline 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 is marketing copy that largely restates the name: 'a viral content precheck system' with 'a structured, repeatable workflow.' It never says what a 'precheck' actually is — whether it scores, audits, critiques, or rewrites content — and it gives no basis for distinguishing this from viral-copywriter, viral-hook-writer, or viral-campaign-sop in the sibling list.

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 context is an audience statement ('for marketing and operations leaders'), not usage guidance. There is no when-to-use, no when-not-to-use, and no named alternative among the many viral-* siblings. An agent has no signal for choosing this over viral-copywriter or viral-topic-miner.

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