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

With no annotations provided, the description carries the full burden of behavioral disclosure. While it mentions the optional 'start' functionality, it doesn't describe what happens during discovery (e.g., scanning processes, checking ports), what 'autoStart' actually does (e.g., launches process, establishes connection), timeout behavior, error conditions, or what constitutes successful discovery. For a tool with 3 parameters and no annotation coverage, this is inadequate.

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 perfectly concise at 5 words, front-loading the core functionality ('Find and optionally start') immediately. Every word earns its place, with no redundant phrases or unnecessary elaboration. The structure efficiently communicates the essential action and target.

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 tool's complexity (3 parameters, no annotations, no output schema), the description is insufficiently complete. It doesn't explain what the tool returns (client handle? status object?), what happens during discovery failures, or how the parameters interact. For a client management tool with multiple configuration options, more context about behavior and outcomes is needed.

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?

With 0% schema description coverage, the description provides no information about any of the 3 parameters. It doesn't explain what 'clientType' values represent, what 'autoStart' controls, or what 'timeout' affects. The description fails to compensate for the complete lack of parameter documentation in the schema, leaving all parameters semantically ambiguous.

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's purpose with a specific verb ('Find and optionally start') and resource ('MCP client'), making it immediately understandable. It distinguishes itself from the sibling 'tools/call' by focusing on client discovery/startup rather than tool invocation. However, it doesn't specify what constitutes 'finding' a client (e.g., local discovery vs. network scanning).

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 provides no guidance on when to use this tool versus alternatives. There's no mention of prerequisites, typical use cases, or comparison with the sibling 'tools/call' tool. The agent receives no help in determining whether this is for initial client setup, runtime client management, or troubleshooting scenarios.

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

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

With no annotations provided, the description carries full burden for behavioral disclosure. While 'Execute a tool' implies a potentially state-changing operation, the description doesn't specify whether this is read-only or destructive, what permissions are required, whether there are rate limits, or what happens on failure. It provides minimal behavioral context beyond the basic action.

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 at just 6 words, front-loading the core purpose with zero wasted language. Every word earns its place in communicating the essential function.

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 tool with 3 parameters (2 required), 0% schema coverage, no annotations, and no output schema, the description is inadequate. It doesn't explain what the tool returns, how to interpret results, error conditions, or provide any parameter guidance. The description leaves too many open questions for effective agent use.

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?

With 0% schema description coverage for all 3 parameters, the description provides no information about what 'method', 'arguments', or 'targetType' represent. The description doesn't explain what constitutes a valid method name, what format arguments should take, or what the 'claude'/'cline' enum values mean. It fails to compensate for the complete lack of schema documentation.

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 action ('Execute a tool') and target ('on a remote MCP client'), providing a specific verb+resource combination. However, it doesn't explicitly differentiate from its sibling 'discover_client', which appears to be a different type of operation (likely discovery vs. execution).

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 provides no guidance on when to use this tool versus alternatives. There's no mention of prerequisites, appropriate contexts, or comparison with the sibling tool 'discover_client'. The agent must infer usage from the tool name and description alone.

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