krdevui_sig_has_signature

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It only states the positive condition (true if mark exists) and does not mention error behavior, file access implications, what happens when the file is missing, or the return value for the negative case. The mention of 'sigchecker CheckExeHasSignature' adds no meaningful behavioral context.

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 is direct and front-loaded with the key condition. No unnecessary words or details are present, 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?

For a simple boolean predicate with one parameter and no annotations, the description provides the core information. However, it lacks context about the XRELEASE_SIG____ mark, the return format beyond 'True', and how it relates to sibling signature tools. Given the tool's simplicity, this is borderline adequate but leaves room for clearer usage context.

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 0%, so the description must compensate. It implies that 'path' refers to an EXE file but does not explicitly define the parameter, its expected format, or constraints. The single parameter remains minimally described, leaving the agent to infer that the path points to a file to be checked.

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 tool's function: it returns true if an EXE has the XRELEASE_SIG____ mark. This is specific and distinguishes it from siblings like krdevui_sig_check or krdevui_sig_sign by referencing a particular mark and underlying function. However, it lacks an explicit verb like 'checks' or 'returns', relying on 'True if' to convey the action.

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. The sibling tools krdevui_sig_inspect, krdevui_sig_check, and krdevui_sig_sign likely overlap in purpose, but the description does not clarify what makes this tool the right choice for specific scenarios.

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