roku_debug_breakpoints_add

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

With no annotations provided, the description carries the full burden of explaining behavioral traits, but it only says 'Add breakpoints' and lists the input shape. It does not disclose whether existing breakpoints are replaced, whether duplicates are allowed, whether a debug session must be active, or what side effects the operation has.

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 short and front-loaded with the primary action, and every word contributes to understanding. It is concise but slightly under-structured because the breakpoint object is shown in a compact inline notation rather than a clearer field-by-field form.

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?

This is a simple one-parameter tool with an output schema available, so the description covers the core input shape adequately. Still, missing semantics around ignore_count and the lack of any behavioral or usage context make it only minimally complete for an agent operating in a large sibling-tool ecosystem.

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's breakpoints items object is empty, so the description adds real value by specifying each breakpoint's fields: file_uri, line_num, and optional ignore_count. However, it stops short of defining types, the meaning of ignore_count, or any constraints, so the agent still has to infer important details.

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 action ('Add breakpoints') and augments it with the expected per-breakpoint shape, so the tool's purpose is unmistakable. It does not explicitly differentiate from siblings like remove or list, but the verb 'add' is specific enough to avoid most confusion.

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 given about when to use this tool versus the many breakpoint-related siblings such as roku_debug_breakpoints_remove or roku_debug_breakpoints_remove_all. The intended use is implied by the name, but there are no explicit conditions, prerequisites, or exclusions.

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