run_pentest_scan

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

With no annotations provided, the description carries full behavioral disclosure responsibility. It does mention 'non-destructive', indicating safety, and scopes to dev endpoints. However, it does not clarify whether payloads are actually sent or just generated, nor mention permissions, rate limits, or potential side effects, leaving gaps in transparency.

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, compact sentence that front-loads the core action ('Generates non-destructive exploit payloads') and provides necessary details without unnecessary verbosity.

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?

The tool has moderate complexity with two parameters and no output schema. The description explains the tool's purpose and scoping but fails to describe expected return values, whether requests are sent, or any post-scan behavior, leaving the agent without a full picture of what happens when the tool is invoked.

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 schema covers targetUrl with a description, but payloadTypes lacks a description. The description adds examples of payload types (SQLi, XSS, JWT tampering) but omits path_traversal from the enum, providing incomplete compensation for the 50% schema coverage gap.

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: generating non-destructive exploit payloads (SQLi, XSS, JWT tampering) to test input sanitization on dev endpoints. It uses specific verbs and resources, and distinguishes itself from sibling tools like run_vulnerability_scan by focusing on payload generation for pentest purposes.

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 clear context for use: it targets 'configured dev environment endpoints' and tests input sanitization, implying it is suitable for development environments. It lacks explicit exclusions or alternative tool comparisons, but the context is clear enough to guide appropriate use.

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