v1.0.0Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description must disclose behavioral traits. It states the tool returns a list of template names and encoders, implying a read-only operation. However, it does not specify if calls to msfvenom are made each time, caching behavior, or any side effects. This is adequate for a simple list, but not fully transparent.
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 two lines: one sentence stating the purpose and a 'Returns:' line specifying the output. It is concise, front-loaded, and every word adds value. No fluff.
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 no parameters and an output schema exists, the description sufficiently covers the tool's functionality. It explicitly notes the return value (template names and encoders). The context signals indicate high schema coverage and presence of output schema, so no further detail is needed.
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?
There are no parameters, so schema coverage is 100% trivially. The baseline for zero parameters is 4, and the description adds no parameter info beyond what's implied (none needed). No improvement required.
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 explicitly states the tool lists 'available payload templates and encoders for msfvenom', with a clear verb ('List') and resource ('payload templates and encoders'). Among siblings like 'payload_generate' and 'payload_list', this distinguishes itself by focusing on msfvenom-specific templates and encoder listings.
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 'payload_generate' or 'payload_list'. The description does not mention prerequisites, scenarios, or exclusions, leaving the agent to infer usage without context.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
