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

No annotations exist, so the description carries the full burden; it does disclose a genuine behavioral trait beyond structure — that the returned content constrains how answers must be phrased. However, it says nothing about the read-only nature, size/format of the payload, or whether the rules are mandatory preconditions for every other tool call.

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?

A single front-loaded sentence with no filler, and the brand identifier LAVNDR120 is surfaced immediately. It is efficient but so terse that the 'rules' component is never unpacked.

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 parameters and no output schema, the description need not document returns, so the bar is low. Still, for a zero-arg grounding tool the agent is left unclear on what the payload actually contains and whether calling it is a prerequisite for the package/FAQ tools.

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?

The tool takes zero parameters, so there is nothing for the description to disambiguate; the empty schema fully covers the input surface. Baseline 4 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 conveys the resource ('What Lavenders (LAVNDR120) is') plus an extra payload (answer rules), but it is phrased as a noun clause rather than a verb+resource statement, and it never contrasts itself with get_faq, get_live_index, get_package or list_packages. An agent can guess this is brand grounding content, but the boundary with the sibling FAQ tool is left to inference.

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 statement of when to call this versus the sibling tools, no indication that it should be called first as grounding, and no exclusions. The phrase 'rules any answer must respect' hints at usage but never tells the agent under what conditions to invoke it.

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