set_breakpoint

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

The description lacks behavioral details beyond the basic action. It does not disclose whether breakpoints are persistent, if setting a breakpoint affects other breakpoints, or any implications for runtime debugging. With no annotations, the description carries the full burden and falls short.

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 sentence that directly states the tool's purpose without unnecessary words. It is clear and efficient, though additional details could be added without losing conciseness.

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 low complexity (3 parameters, no enums, no output schema) and absence of annotations, the description tells what the tool does but omits necessary context like prerequisites (e.g., must the script be open? must the game be running?). It is minimally complete but leaves gaps.

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 already documents all three parameters. The description adds no additional meaning beyond what the schema provides (e.g., 'optionally with a condition' mirrors the condition parameter). Baseline score of 3 is appropriate.

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 ('Set a breakpoint'), the resource ('in a GDScript file'), the specific location ('at a specific line'), and the optional feature ('optionally with a condition'). It distinguishes from sibling tools like 'list_breakpoints' and 'remove_breakpoint'.

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 provided on when to use this tool versus alternative debugging tools such as 'step_into', 'step_over', or 'continue_execution'. An explicit mention of the debugging context or hints about appropriate scenarios would improve the score.

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