fetch_public_page

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

With no annotations, the description carries full burden. It discloses 'no API key' (authentication) and the extract_text behavior, but lacks details on error handling, rate limits, or handling of non-GitHub pages. Minimal behavioral info beyond parameter effects.

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?

Extremely concise with two sentences plus args list. Purpose is front-loaded with no extraneous words. Every sentence adds value.

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?

Reasonably complete for a simple fetch tool with an output schema present. Covers purpose, parameter semantics, and usage context. Missing explicit error conditions or non-GitHub handling, but adequate overall.

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?

Despite 0% schema description coverage, the description adds meaningful parameter explanations: page_url example and extract_text meaning with default. This compensates well for the bare 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?

The description clearly states 'Fetch a public web page' and specifies it's good for GitHub Pages, distinguishing it from sibling tools like audit_live_site or read_repo_file. However, it lacks explicit differentiation from siblings.

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 for GitHub Pages sites but provides no when-not-to-use guidance or explicit alternatives among siblings like audit_live_site or get_repo_overview. Usage is inferred but not fully outlined.

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