adb_test_session_end

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

With no annotations, the description discloses the main actions and return value, but lacks details on error handling (e.g., no active session) or side effects beyond writing the manifest.

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 a single sentence that is concise and front-loaded, with no extraneous information.

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, the description adequately covers the action and return, but could elaborate on the manifest content for completeness.

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 input schema has no parameters, so schema coverage is 100%. Baseline of 4 applies; the description does not need to add parameter info but could mention return value format.

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 what the tool does: ends the active test session, writes a summary manifest, and returns the session directory path. It distinctively differentiates from siblings like adb_test_session_start and adb_test_step.

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 after starting a session, but does not explicitly state when to use or when not to use, nor mentions alternatives like adb_test_session_start for starting.

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