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

No annotations are provided, so the description carries the burden. It states it returns 'full raw content,' implying a read operation, but does not explicitly say it is side-effect-free or describe any potential performance or payload size implications. It is not contradictory, but the absence of an explicit read-only declaration and any behavioral caveats keeps this at a mid-range score.

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 with no wasted words. It immediately states what the tool returns and how to obtain the required id, making it highly scannable for an agent.

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 retrieval tool, the description is sufficient: it explains the output ('full raw content') and the input source (id from android_crash_analytics). It does not describe pagination or size, but that is not critical for a detail fetch. The absence of an output schema is acceptable since the description clearly indicates the return type. It could explicitly mention it is a read-only operation, but that is implied by the nature of the tool.

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 input schema already fully documents both parameters (id and serial) with descriptions that match the tool's purpose. The description reinforces that the id comes from android_crash_analytics, but adds no new semantic detail beyond the schema. With 100% schema coverage, the baseline of 3 is appropriate.

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 clear verb ('get') and specific resource ('full raw content of one crash/ANR/tombstone entry'), and identifies how to reference it ('by id from android_crash_analytics'). It differentiates itself from the sibling listing tool android_crash_analytics, making its purpose unambiguous.

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 explicitly tells the agent that the id comes from android_crash_analytics, implying a prerequisite workflow: first list crashes, then fetch detail. This provides clear guidance on when to use this tool versus the sibling listing tool, and the android-specific context differentiates it from the ios_crash_detail sibling.

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