adb_version

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

No annotations are provided, so the description carries the full burden. It does disclose the returned content (version string plus resolved path) and implicitly signals a side-effect-free, read-only query, but it says nothing explicit about whether the adb binary is probed, what happens if adb is missing, or whether a device connection is required. Adequate but shallow.

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?

One front-loaded sentence with zero filler; both facts the caller needs are in the first clause. Nothing is repeated from the schema or elsewhere.

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 no-parameter, output-schema-backed informational tool, the description is complete: it says what is returned and which side (host vs device) it applies to. Return-value formatting is already covered by the output schema, so no further detail is required.

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 tool takes zero parameters, so per the rubric the baseline is 4. Nothing in the description contradicts or misrepresents the empty argument object.

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?

States a specific verb ('Return') and precisely names the two resources produced: the host adb client version string and the resolved adb path. The phrase 'host adb client' disambiguates it from device-side siblings like get_prop, get_device_properties, or get_state, none of which report client-side binary information.

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?

There is no explicit when-to-use, when-not-to-use, or alternative named. Usage is only implied by the description itself (call it when you need the adb client version or its resolved path), which is the definition of implied guidance. For a trivial zero-argument informational tool this is tolerable, but nothing is stated.

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