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

Annotations already declare readOnlyHint, idempotentHint, and openWorldHint=false, so the safe-read profile is covered. The description adds content-scope context (it covers the dashboard and per-region payment mechanics), which is useful, but it says nothing about output format, length, or depth — a modest addition over the annotations.

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 short sentence with no padding, and the main subject leads. It is efficient, though the fragmentary phrasing ('What Foodly does...') reads more like a section heading than a complete directive.

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?

For a zero-argument read tool with no output schema, the description identifies the topics covered, which is the main thing an agent needs. However, it does not indicate depth, return structure, or how it relates to the four sibling tools, leaving a routing gap.

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 at the parameter level. 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 lists topic areas (what Foodly does, the web dashboard, regional payments) but is a noun fragment with no verb, and the title 'What Foodly is' largely restates it. It does differentiate somewhat from siblings like get_foodly_plans or find_foodly_region by framing itself as a broad product overview, but the scope is vague rather than stated as a specific action.

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 guidance on when to call this versus get_foodly_start, get_foodly_plans, or get_foodly_faq. An agent must infer that this is the entry-point/overview tool from the name alone; no exclusions or alternatives are named.

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