create_http_source

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

No annotations are provided, so description must disclose side effects. 'Create' implies a mutation, but the description does not mention idempotency, uniqueness constraints, permissions, or failure modes. Only the return value is described, which is helpful but insufficient for full behavioral 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?

Two sentences, front-loaded with the primary action, and the second sentence adds meaningful return info. No filler.

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?

With output schema present and parameters fully described, the description is mostly complete for straightforward creation. However, it lacks any guidance on preconditions (beyond hosted collector) or error scenarios, so it falls short of fully equipping an agent.

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 covers 100% of parameters with descriptions, so the description adds no parameter-level meaning. Baseline of 3 applies; the description doesn't go beyond schema.

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?

Description uses specific verb 'Create' with resource 'HTTP source on a Hosted collector', clearly distinguishing from sibling tools like create_hosted_collector. It also mentions the return of endpoint URL, further clarifying what the tool produces.

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?

Stated 'on a Hosted collector' provides context about where the source is created, implying the collector must exist and be hosted. However, no explicit when-to-use vs alternatives or exclusions are given, so it earns a 4.

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