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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It states the action ('continue execution from the current position') but doesn't cover critical aspects like whether this requires a connected/halted state, potential side effects, error conditions, or what the output schema contains. For a tool with zero annotation coverage, this is insufficient.

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, clear sentence in Chinese that directly states the tool's function without any fluff or redundancy. It's appropriately sized and front-loaded, making it easy for an agent to parse quickly.

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 0 parameters, an output schema exists, and no annotations are provided, the description is minimally adequate. However, it lacks details on behavioral context (e.g., state requirements) and doesn't leverage the output schema to hint at return values. For a tool interacting with hardware debugging, more completeness would be beneficial.

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 tool has 0 parameters, and the input schema has 100% description coverage (though empty). The description doesn't need to explain parameters, so it meets the baseline. A 5 would require adding value beyond the schema, but with no parameters, there's little opportunity for enhancement.

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 ('繼續執行' meaning 'continue execution') and the target ('目標晶片的 CPU' meaning 'target chip's CPU'), which is specific and unambiguous. However, it doesn't explicitly differentiate from sibling tools like 'jlink_step' (single-step) or 'jlink_halt' (stop), which would require 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?

The description provides no guidance on when to use this tool versus alternatives. It doesn't mention prerequisites (e.g., the CPU must be halted first), exclusions, or comparisons to siblings like 'jlink_step' for stepping or 'jlink_reset' for restarting. This leaves the agent without contextual usage information.

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