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

With no annotations, the description carries full burden for behavioral disclosure. It does not specify return type (e.g., boolean), whether it is read-only, or any side effects. The description is insufficient for an agent to understand behavior beyond the basic action.

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?

The description is brief and front-loaded: the first sentence conveys the purpose, followed by a clear parameter listing. It avoids unnecessary words, but could additionally specify return value in the same concise manner.

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 tool with one parameter and no output schema, the description is incomplete. It fails to mention the return value (e.g., boolean) and any behavioral traits like read-only nature. An agent cannot fully anticipate the tool's output.

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 description's 'Args' section adds minimal semantic information over the schema: it specifies the path must point to a Mach-O binary. However, schema coverage is 0% (no param descriptions), so the description provides the only explanation. This is adequate for a single required 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?

The description clearly states the action ('Check if') and the target ('Mach-O binary is encrypted'), specifying FairPlay DRM, which distinctively separates it from sibling tools like 'check_encryption' and 'dynamic_check_cryptid'.

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 is provided on when to use this tool versus alternatives such as 'check_encryption' (likely for general encryption checking) or 'dynamic_check_cryptid'. The description lacks context for appropriate usage.

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