adb_ota_fingerprint

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

No annotations provided, so description carries full burden. It mentions capturing and saving to a file but does not explicitly state that the tool is read-only or non-destructive. Behavioral traits like file creation location or impact on device state are missing.

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?

Two concise sentences with clear action and output. No unnecessary words; front-loaded with key attributes captured.

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?

Given no output schema, the description adequately lists captured fields and output format (timestamped JSON). It's complete for an agent to understand purpose and outcome, though could note that it does not modify the device.

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 coverage is 100% with descriptions for both parameters (label default 'current', device serial). Description does not add extra meaning beyond the schema; it remains at baseline adequacy.

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?

Description clearly states the tool captures the current system fingerprint including specific attributes like build ID, Android version, security patch, etc., and saves it to a timestamped JSON file. This distinguishes it from siblings by focusing on saving a snapshot for comparison.

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 implies usage for capturing a fingerprint before/after OTA updates for later comparison, but does not explicitly state when to use this tool compared to siblings like adb_ota_check or adb_firmware_diff. No guidance on when not to use it.

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