get_recent_requests

Retrieve recent network requests with 512-byte request and response body previews to inspect web traffic. Set the number of requests and optionally include headers for a more comprehensive view.

Instructions

Get recent network requests compact overview with 512B request/response body previews. Shows both request and response body previews separately.

Behavior3/5

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

No annotations are provided, so the description carries the burden. It discloses the 512B body preview limit and that request/response bodies are shown separately, but does not mention ordering, filtering, read-only behavior, or what happens when bodies exceed the limit.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is two concise sentences with the purpose front-loaded. Every word contributes value, and there is no unnecessary repetition or filler.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a simple tool with two optional parameters and no output schema, the description explains the core purpose and a key limitation (512B previews), but does not detail the exact response structure beyond 'compact overview' and separate previews. This is adequate but not exhaustive.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The input schema covers both parameters (count and include_headers) with descriptions, so the description adds no extra parameter semantics beyond what the schema already provides. Baseline 3 is appropriate.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool gets recent network requests as a compact overview with 512B request/response body previews. The phrase 'compact overview' distinguishes it from sibling get_request_detail, which likely provides full details.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description implies this tool is for a compact overview of recent requests, but it does not explicitly state when to use it versus alternatives like get_request_detail, nor does it provide exclusions or when-not-to-use guidance.

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