apk_fingerprint

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

With no annotations provided, the description carries the full disclosure burden. It does add genuine behavioral context — 'fast' and 'without a full decompile' signal a lightweight, presumably non-destructive analysis pass. But it is silent on side effects, whether output is persisted to a case/file, preconditions on the APK, and failure 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 nine-word sentence that front-loads the operation and scope, then ends with the cost qualifier ('without a full decompile'). Every word carries signal with zero filler or repetition of the tool name.

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 one-required-parameter tool with an output schema present, the core action is adequately covered and return values need not be re-explained. But the description omits how this fits the sibling workflow (e.g., whether a case must exist first), any preconditions on the APK, and what consuming the fingerprint entails. The output schema mitigates the return-format gap, but overall context is thin.

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 0% and the description never mentions apk_path explicitly, so the burden is on the description to compensate. The tool name and fingerprinting context make it inferable that apk_path is the path of the APK to fingerprint, but no format, locality (local vs. remote), or validation semantics are given. Weak compensation for a low-coverage schema.

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 specific operation — fingerprinting an APK — with an explicit scope: framework/HTTP/SDK/native characteristics. The qualifier 'without a full decompile' plus the unique 'fingerprint' concept cleanly separates it from the sibling suite (create_case, dispatch, status, report, etc.), none of which overlap. It stops short of 5 because the verb is implicit ('fingerprint' used as a noun-as-verb) and it doesn't state what form the fingerprint output takes.

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?

'Without a full decompile' and 'fast' implicitly position this as the lightweight option when a quick fingerprint suffices, implying that a full decompile path is the alternative. However, no sibling tool is named, and there is no explicit when-to-use/when-not-to-use guidance relative to the case/dispatch/orchestrate workflow.

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