desmume_executable_ranges_replace

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

With no annotations, the description carries the full burden. It does disclose that the change is 'session-scoped', implying the modification is not persistent, which is useful. However, it does not mention validation behavior, atomicity, or effects on the emulator runtime, leaving significant 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 a single, front-loaded sentence with no unnecessary words. It states the verb and the object clearly, making it highly concise and easy to parse.

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 complex schema and absence of an output schema or annotations, the description is too sparse to guide an agent on the tool's role in a workflow or its return behavior. It lacks information on when to invoke it relative to other desmume tools or what outcomes to expect.

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 description adds no detail about the 'ranges' parameter beyond its name, even though the schema is complex with nested properties. Since schema description coverage is 0%, the description should compensate, but it only implicitly connects 'executable-range' to 'ranges' without any format, constraints, or examples.

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 the specific verb 'Replace' and identifies the resource as the 'session-scoped additional ARM9 executable-range allowlist', clearly distinguishing it from sibling breakpoint and memory tools. However, it does not explicitly mention when this tool should be used over alternatives, so it falls short of a 5.

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 alternatives like desmume_breakpoint_add or desmume_breakpoint_list. The description only states the action itself and gives no context on prerequisites, exclusions, or typical scenarios.

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