execution

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

With no annotations provided, the description carries the full burden of disclosing behavior. However, it only states the verb 'resume or pause' without explaining side effects (e.g., what pausing does to the running script, whether resume continues to the next breakpoint or completes execution). This lack of detail is a significant gap for a debugger control tool.

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, front-loaded sentence that directly conveys the core function. It is efficient with no wasted words. However, given the tool's role in a debugger toolset, slightly more structural context (e.g., a parenthetical about what 'execution' refers to) would improve scannability without adding bulk.

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 two parameters and no output schema, this description is too thin to be fully self-sufficient. It does not explain the effect of pause/resume on the execution flow, when to use it within a debugging session, or how 'connection_id' influences behavior. The sibling tools provide some context, but the description alone is inadequate.

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 100% description coverage for both parameters, with the 'action' enum clearly described as '"resume" or "pause"' and 'connection_id' described as 'Chrome connection to use'. The tool description adds no additional meaning beyond the schema, so the baseline of 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's action: 'Resume or pause execution.' This is a specific verb+resource pair that conveys the core functionality. However, it does not explicitly differentiate from sibling tools like 'step' or 'breakpoint', which are also related to execution control in a debugger context.

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?

No guidance is provided on when to use this tool versus alternatives. There is no mention of scenarios where this is preferred over 'step', 'breakpoint', or 'pause_on_exceptions'. The description simply states what it does without offering context for selection, leaving the agent to infer usage solely from the tool name and siblings.

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