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

No annotations are supplied, so the description carries the full burden. It does disclose the delivery form ('copy-paste prompt pack with examples'), which tells the agent the output skews toward reusable template content rather than computed analysis. However, it says nothing about permissions, whether the optional query is consumed or ignored, or the return structure, leaving real behavioral gaps for a zero-annotation tool.

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?

At two sentences it is short and front-loaded, so there is no padding to cut. But the space is spent on marketing phrasing ('production-ready', 'repeatable workflow you can run today') rather than the concrete capability an agent needs.

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 annotations and no output schema, the description is the only source of truth for this tool, and it does not resolve the central ambiguity of audience and domain. It never explains what a caller receives or how the optional query influences it, which is inadequate even for a simple one-parameter tool.

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?

There is a single optional parameter with 100% schema description coverage, so baseline 3 applies. The description adds no meaning about how the 'query' scopes the generated plan, and it is especially unclear whether the query is honored at all given the 'prompt pack' framing.

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 never states a clear verb+resource action: it calls itself 'a production-ready second baby plan system for marketing and operations leaders' and says it is 'delivered as a copy-paste prompt pack with examples.' The name and sibling context (baby-food-menu, baby-sleep-planner, breastfeeding-guide) suggest a family/parenting planning resource, but the description reframes it for marketers, so an agent cannot tell what domain the tool actually serves. The output form is hinted at, but the core purpose remains ambiguous.

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 exclusions, and no named alternative among the many sibling planners (baby-sleep-planner, four-six-plan, year-plan-generator). The phrase 'you can run today' is a sales claim rather than a usage condition. An agent has no basis for choosing this over another plan-style tool.

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