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 describes the output contents structurally but omits whether this operation consumes credits, requires an existing product, persists a plan server-side, or how long it takes. For a generation tool in a suite that includes check_credits, these omissions are significant.

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?

One sentence with no filler, and the most important information (output type, time horizon, and contents) is front-loaded. Every phrase earns its place.

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 output schema and no annotations, the description is the only source of shape information, and it partially covers this by naming the plan's components. It is missing behavioral context such as credit cost, persistence, and required auth, which matters for a generation tool. Adequate but with clear gaps.

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 coverage is 100% and there is a single optional parameter (productId), whose default behavior is already documented in the schema. The description adds no additional meaning about the parameter, so 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 gives a specific verb ('Generate') and resource ('a 3-week content plan') plus the concrete deliverables: daily posting schedule, hooks, and platform rotation. An agent can distinguish this from siblings like analyze_hook, remix_hook, or suggest_captions based on the scope of the output. It stops short of explicitly contrasting with those siblings, so a 4 rather than a 5.

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, no indication of prerequisites, and no mention of alternatives such as suggest_captions or scrape_video for adjacent content tasks. The only usage hint is self-evident from the verb. The presence of a sibling check_credits tool suggests cost considerations that the description never addresses.

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