debuggerSetBreakpoints

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

With no annotations provided, the description carries full burden but offers no behavioral details. It doesn't disclose if this is a read or write operation (implied mutation from 'Sets'), what permissions are needed, side effects (e.g., pausing execution), rate limits, or response format. This is inadequate for a tool with 10 parameters and no output schema.

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 with just two words, front-loading the core action. There's no wasted text, making it efficient to parse, though this conciseness comes at the cost of completeness.

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 (10 parameters, no annotations, no output schema), the description is severely incomplete. It lacks purpose differentiation, usage context, behavioral details, and any explanation of what 'Sets breakpoints' entails, making it inadequate for effective tool selection and invocation.

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%, so the schema documents all parameters. The description adds no meaning beyond the schema, such as explaining relationships between parameters (e.g., how breakpoints interact with debuggingMode) or usage examples. Baseline 3 is appropriate as the schema handles parameter 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 'Sets breakpoints' is a tautology that merely restates the tool name without adding specificity. It doesn't clarify what kind of breakpoints (e.g., in a debugger session, for specific code), what resources are involved, or how this differs from sibling debugger tools like debuggerDeleteBreakpoints or debuggerListen.

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. It doesn't mention prerequisites (e.g., needing an active debugger session), context (e.g., during debugging workflow), or distinctions from related tools like debuggerDeleteBreakpoints or debuggerListen, leaving the agent with no usage context.

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