adb_multi_compare

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

No annotations are provided, so the description carries full burden. It fails to disclose execution behavior (e.g., parallel vs sequential, timeout, error handling for unresponsive devices, or output format). Adding basic behavioral traits would significantly improve transparency.

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 extremely concise: two sentences (15 words). It is front-loaded with the action and immediately provides the key differentiator (highlights differences). No unnecessary words.

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 the absence of output schema and moderate complexity (multi-device command comparison), the description should explain output format, how differences are highlighted, and behavior on partial failures. It does not, leaving the agent with incomplete expectations.

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% with adequate descriptions for both parameters. The description adds 'side by side' and 'highlights differences' but does not elaborate beyond schema. Baseline 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 clearly states the tool runs a command on all devices and compares outputs side by side, highlighting differences. It specifies the verb (run and compare), resource (command on devices), and outcome. This distinguishes it from single-device tools like adb_shell and adb_multi_shell which do not compare.

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 use for comparing outputs across devices, but lacks explicit guidance on when to use versus alternatives. It does not mention exclusions (e.g., when not to use) or mention sibling tools. The context is clear but not prescriptive.

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