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

Annotations declare readOnlyHint=false, destructiveHint=false, and openWorldHint=false, so the core safety profile is already clear. The description adds that the tool spends 1000 credits (a critical behavioral trait not in annotations), and auto-activates the campaign. However, it does not mention whether the action is reversible, what happens to unused credits, or if there is a confirmation step beyond user prompt. With no destructive hint, the description could more explicitly state that this is a write-only action that cannot be undone.

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 compact (4 sentences), front-loads the core purpose, and each sentence adds distinct value: what the tool does, credit cost, automation behavior, prerequisites, and usage steps. No wasted words.

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 7 parameters (2 required), no output schema, and moderate complexity, the description covers the core workflow (prerequisite, preview, cost, activation). It is complete enough for an agent to use correctly. Minor gap: it does not mention what happens after activation (e.g., how to track results), but the description 'community submissions and winner selection happen in ProductClank web app' provides sufficient closure.

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%, so the baseline is 3. The description adds that campaign_message is a 'core brief' and that the AI expands the brief, but does not explain how other parameters like references or additional_guidelines interact. It does not add syntax or domain-specific details beyond what the schema already provides. Overall, the description adds marginal value over the 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 clearly states the verb ('launch') and resource ('content campaign'), and specifies the unique scope: rallying a community to create content (posts, threads, videos). It differentiates from siblings like suggest_content_campaign (preview) and boost_post (separate action), and explicitly mentions the required product_id from search_products.

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 description explicitly recommends using suggest_content_campaign for preview first and confirms the 1000-credit cost before calling. It also states the need for a product_id from search_products. However, it does not explicitly state when not to use this tool or compare to other siblings like write_content_candidates, which could be an alternative for creating content.

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