Send HTTP Request

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

With no annotations provided, the description carries full burden and does well by disclosing key behavioral traits: the proxy interception mechanism, visibility in the UI, and the full response structure returned. It doesn't mention error handling, timeout behavior, or authentication requirements, but covers the core operational behavior adequately for a tool with no annotations.

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?

Perfectly concise with two sentences that each earn their place: the first states the core action and context, the second describes the return value. No wasted words, front-loaded with the main purpose, and appropriately sized for the tool's complexity.

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's moderate complexity (5 parameters, no output schema, no annotations), the description provides good contextual completeness. It covers the purpose, operational context (proxy interception), and return format. The main gap is the lack of an output schema, but the description compensates by specifying what's returned. For a mutation tool (sending requests) with no annotations, it could benefit from more safety/error 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 100%, so the schema already documents all 5 parameters thoroughly. The description adds no additional parameter semantics beyond what's in the schema. According to scoring rules, when schema coverage is high (>80%), the baseline is 3 even with no parameter information in the description.

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 specific action ('Send an HTTP request'), specifies the resource ('through the HTTP Toolkit proxy'), and distinguishes this tool from all sibling tools which focus on interception setup, configuration, or traffic capture rather than direct HTTP request execution. It provides a complete purpose statement in the first sentence.

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 implies usage context by mentioning 'through the HTTP Toolkit proxy' and that requests 'will be intercepted and visible in the HTTP Toolkit UI,' suggesting this tool is for testing/monitoring scenarios. However, it doesn't explicitly state when to use this versus alternatives or provide any exclusion criteria. The guidance is contextual but not explicit.

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