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. It effectively adds context beyond the schema by stating the tool is idempotent (a no-op if the same address is added twice), which is a key behavioral trait. However, it lacks details on permissions, rate limits, or error conditions, leaving some gaps.

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 appropriately sized and front-loaded, starting with the core purpose, followed by idempotency note, and then parameter explanations. Each sentence earns its place without redundancy, making it efficient and well-structured for quick understanding.

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 complexity (a mutation tool with no annotations and no output schema), the description is somewhat complete but has gaps. It covers purpose, idempotency, and parameters, but lacks details on return values, error handling, or interactions with sibling tools like 'list_breakpoints'. This makes it adequate but not fully comprehensive for an agent.

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 schema description coverage is 0%, so the description must compensate. It adds meaning by explaining each parameter: 'session_id' as the session ID, 'address' as the address to break at, and 'condition' with examples like 'eax == 42'. This clarifies semantics beyond the basic schema, though it could provide more detail on format or constraints.

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 ('Add') and resource ('breakpoint at the given address'), distinguishing it from sibling tools like 'remove_breakpoint' or 'list_breakpoints'. It precisely defines what the tool does without being vague or tautological.

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 clear context by mentioning idempotency, which helps understand when to use it (e.g., safe to call repeatedly). However, it does not explicitly state when not to use it or name alternatives like 'remove_breakpoint' for different scenarios, leaving some guidance implicit rather than explicit.

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