fetch_https_response

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It explains the allowed-domain restriction, the 2 MB response cap, and the text-only nature of the response. It does not discuss error behavior or authentication, but for a simple HTTPS text fetcher the disclosed constraints are meaningful and sufficient.

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 compact and front-loaded with the core action. The bullet list of use cases is scannable and every sentence contributes useful information without redundancy.

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 is simple with one parameter and an output schema, so the description does not need to detail return values. It covers the main constraints, use cases, and limitations. It could slightly improve by naming sibling alternatives, but overall it is complete enough for an agent to call it correctly.

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 has 0% description coverage and only one parameter, 'url'. The description compensates by clarifying that the URL must be HTTPS, belong to an approved domain set, and yield a text response no larger than 2 MB. This adds real meaning beyond the bare 'url' field, though it does not provide an exhaustive allowed-domain list.

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 names a specific action and resource: 'Fetch text from an approved HTTPS URL.' It clearly distinguishes itself from siblings like download_file (binary content) and read_file (local files) by emphasizing text-only output from approved remote HTTPS sources. The 'Useful for' list reinforces its intended scope.

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 usage context: fetching release metadata, documentation, GitHub API responses, and text configuration files. It also states the domain restriction, which implicitly tells the agent this is not for arbitrary web pages. However, it does not explicitly contrast with fetch_web_page or download_file.

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