timps_api_security_tester

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

With no annotations present, the description carries the full behavioral burden. It does disclose a meaningful trait—that the tool comes 'with a runnable test harness'—which hints at code generation behavior. However, for a security-audit tool that may probe live endpoints, the description is silent on side effects (e.g., whether it sends harmful requests, requires auth tokens, or has rate limits). An agent deciding whether invocation is safe lacks critical context here.

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?

A single, well-constructed sentence that front-loads the verb and payload, uses an em-dash list for scannability, and ends with the key differentiator ('with a runnable test harness'). Every clause carries meaning—no filler, no repetition of the name.

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 tool with only 2 simple, well-documented parameters and no output schema or nested objects, this description provides sufficient context: what it audits, against what standard, with what inputs, and one key output trait (runnable harness). It's slightly light on what the tool returns (test report? generated files?), but given the low complexity, it's nearly complete.

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 coverage is 100%—both 'request' and 'language' have descriptive inline help ('Plain-English task or context for the agent', 'Primary programming language (default: python)'). The description's 'runnable test harness' hints at the language parameter's role in code generation but doesn't go beyond what the schema already conveys. Baseline 3 is appropriate since the schema does the heavy lifting.

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 a specific verb+resource combination ('Run an OWASP API Security Top-10 (2023) audit...against an OpenAPI spec or live endpoint') and enumerates concrete vulnerability classes (broken auth, BOLA, mass assignment, rate-limit, SSRF, injection), distinguishing it from the many sibling tools. This clearly separates it from related tools like timps_security_guard and timps_red_team_agent, which remain generic by comparison.

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 on when to use the tool—when an OWASP API Top-10 audit is needed—and even specifies acceptable inputs ('against an OpenAPI spec or live endpoint'). However, it doesn't reference any alternatives or exclusion criteria (e.g., when to prefer timps_red_team_agent or timps_security_guard instead), so it stops short of a full 5.

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