TDQS

A4/5.0
Behavior3/5

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

With no annotations provided, the description carries the full burden. It discloses 'Read-only', a key safety trait, but it does not describe error behavior (e.g., what happens if the version is not found) or any prerequisites beyond the parameter schema. This leaves notable gaps for a getter.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is concise and front-loaded: 'Read-only.' is stated first, followed by a single clear sentence. There is no filler, and every word contributes to understanding the tool's purpose.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the tool's low complexity (2 well-documented params, no nested objects) and no output schema, the description is mostly sufficient. It clearly states what the tool does and its read-only nature. However, it omits mention of not-found behavior or return format, which is a minor gap for completeness.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The schema has 100% description coverage for both parameters, so the baseline is 3. The description adds minimal extra meaning by clarifying 'by its version string' as the lookup key, but it does not provide additional format details or edge-case semantics beyond the schema.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description 'Gets a single App Store version by its version string' specifies a clear verb ('Gets'), resource ('a single App Store version'), and scope ('by its version string'). It distinguishes this tool from siblings like asc_versions_list (which lists versions) and mutation tools like asc_version_create.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description implies use when you need a specific version by its version string, providing clear context. However, it does not explicitly mention alternatives or when-not-to-use scenarios, such as preferring asc_versions_list when listing all versions.

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