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

With no annotations, the description must carry behavioral disclosure, and it does reveal that feedback is public, shown with your name at /feedback. That is useful visibility context. However, it omits that this is a write/mutation operation, whether feedback can be edited or deleted, authentication requirements beyond the token schema, and any rate or permission limits.

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?

Two compact sentences plus a clean rating scale. The purpose is front-loaded, and the public-visibility note is placed appropriately at the end. Every sentence adds useful information with no filler.

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?

Given six parameters, no output schema, and no annotations, the description covers the core purpose, the rating scale, and the public visibility of feedback. It leaves usage timing and mutation details unspecified, but the most important behavioral and semantic gaps are addressed well enough for an agent to invoke correctly.

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 description coverage is 67%, so the description has a meaningful gap to fill. It supplies the crucial 1–5 rating semantics that the schema only bounds numerically, and its phrasing maps concepts to the played, rating, and suggestions parameters. It does not explain the activity enum or the token fallback, keeping it from a 5.

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 states a specific action (tell the builders) and the exact content expected: what you played, enjoyment, and changes. It clearly distinguishes this from unrelated siblings like join_game or make_game_move, though it does not name alternatives. A 4 rather than 5 because sibling differentiation is implicit rather than explicit.

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?

The description gives no explicit when-to-use, when-not-to-use, or alternative-tool guidance. 'What you played' weakly implies using it after an activity, but no prerequisites or timing rules are stated. This is comparable to the calibration example with no usage guidance.

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