breakpoint

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

No annotations are provided, so the description must carry the transparency burden. It discloses some behavioral traits (e.g., 'await' action 'sets breakpoint and waits for hit - user can abort'), but lacks details on side effects, permissions, or whether breakpoints persist across sessions. This partial disclosure is adequate but not thorough.

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 paragraph that front-loads the core purpose and then enumerates actions in a compact format. While concise, it could be better structured (e.g., bullet points) for faster scanning. Every sentence adds value, but the list format is dense.

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?

With 17 parameters, no output schema, and no annotations, the description covers the primary actions but omits important context like return values (e.g., for 'list' action), parameter combinations, and error handling. It is adequate for basic use but incomplete for complex scenarios.

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 29% (low), so the description is expected to compensate. It lists actions and mentions some parameters (e.g., 'lineNumber' for 'set'), but does not map all 17 parameters to actions. The description adds moderate value beyond the schema, but significant gaps remain for undocumented parameters.

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 'Manage breakpoints and logpoints' and lists 11 specific actions, making the tool's purpose unambiguous. It effectively distinguishes this tool from sibling debugging tools like 'assert' or 'console' by focusing exclusively on breakpoint management.

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 a list of actions but offers no guidance on when to use this tool versus alternatives (e.g., 'assert' or 'network'). There is no explicit 'when-to-use' or 'when-not-to-use' context, leaving the agent to infer usage from action descriptions alone.

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