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

No annotations are provided, so the description carries the full burden. It discloses the algorithm (counting occurrences between min and max), the ordering (ascending), and a pricing/rate trait (5 free trial calls per signed wallet), which is genuine added context. However, it omits constraints inherent to counting sort (e.g., integer/non-negative input limits), output format, and error behavior.

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 that names the tool and its behavior immediately. The trailing emoji/promo clause is minor clutter that does not earn its place in a functional description.

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 simple one-parameter utility with no output schema, the description covers behavior and ordering but leaves the input encoding and returned result shape unspecified, which matters since the schema gives only an untyped string. Adequate but with clear gaps.

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 coverage is 0% for the single 'values' parameter, and the schema types it as a bare string with no description. The description compensates partially by clarifying the expected content ('numeric values array') and ordering applied, but does not state the input encoding (CSV, list, delimiter) needed to actually populate the string parameter.

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?

States a specific verb (sorts) and resource (numeric values array) and specifies ascending order and the counting-sort mechanism. It is clear what the tool does, though it does not distinguish itself from the many sibling sort tools (sort-numbers, bubble-sort, merge-sort, quick-sort, etc.), which is a real gap given the crowded sibling set.

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?

No guidance on when to use counting sort versus the numerous other sorting siblings, and no stated preconditions. The only extra context is a promotional note about free trial calls, which is not usage guidance.

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