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 the shape of the return (prices, inclusions, eight entrees with Toast prices, rules), which is real value, but it never states that this is a side-effect-free read or addresses freshness, currency of prices, or structure.

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 front-loaded sentence with no filler; the resource is named first and the contents follow. Mild deduction for the list-fragment style and unexplained jargon such as 'Toast prices'.

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, the description must convey what comes back, and it does so in concrete terms. What's missing is the relationship to overlapping siblings, which matters in a menu-heavy tool set.

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 and the schema is an empty object, so there is nothing for the description to disambiguate. 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 names a specific resource (Early Bird Dinner) and enumerates the exact content it covers: days/times, pricing tiers, inclusions, entrees, rules. It implicitly distinguishes itself from get_menu and get_specials by scope, though it never explicitly says 'this is the early-bird subset, not the full menu'.

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_menu, get_specials, or get_hours, all of which plausibly overlap. An agent must infer from the name alone that this covers only the early-bird program.

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