get_breakpoint_count

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

No annotations are provided, so the description carries full burden. It clearly states the return value includes both enabled and disabled breakpoints, but does not mention any side effects, permissions, or performance characteristics. For a simple read operation, this is adequate but minimal.

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?

Two concise sentences clearly stating purpose and return value. No unnecessary words. The information is front-loaded with the primary action. Excellent structure for a simple tool.

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 has no parameters and is a straightforward read operation, the description is complete. It explains what it returns and the nuance of counting all breakpoints. The output schema likely covers the technical return type, so no further detail 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?

The input schema has zero parameters, and schema description coverage is 100% (empty). The description adds value by clarifying that the count includes both enabled and disabled breakpoints, which goes beyond the schema. Since there are no parameters, the baseline is high, and this description meets it.

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 uses a specific verb 'Get' and clearly identifies the resource 'total number of breakpoints currently set'. It effectively distinguishes from sibling tools like list_breakpoints, which lists breakpoints rather than returning a count.

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 implies when to use (when a count is needed) but provides no explicit guidance on when not to use or alternatives. No exclusions or context are given, relying on the agent to infer from the name and siblings.

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