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

Annotations already declare readOnly, idempotent, non-destructive, non-open-world behavior, so safety is covered. The description adds that the return is the full raw content (as opposed to a summary), which is useful context, but says nothing about size, pagination, or what 'raw' includes.

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, tight sentence with the return nature and the id source front-loaded. 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?

For a two-parameter read-only tool with full annotation coverage and 100% schema coverage, the description covers what is returned and where the id comes from. It could say more about the raw payload format, but nothing essential to calling it is missing.

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 100%, so both parameters (id and serial) are already documented, and the schema itself states the id comes from android_crash_analytics. The description reinforces but does not extend the schema's parameter meaning.

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 names the specific resource (one crash/ANR/tombstone entry) and its scope (full raw content), which clearly distinguishes it from the analytics/list sibling. The retrieval verb is implicit rather than stated, but an agent can tell exactly what it returns.

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?

It points the agent to android_crash_analytics as the source of the id, implying the fetch-after-list workflow. It does not state when to prefer this over the analytics sibling or any prerequisites/exclusions, so usage is only implied.

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