remove_paywall

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

With no annotations, the description carries the full burden. It transparently lists the sequence of attempts (Googlebot fetch, 12ft.io, archive services) and the prioritization logic, but it doesn't disclose potential failure modes, rate limits, or that some sources may be unreliable. It describes what it does but not edge-case behavioral traits.

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 yet rich: first sentence states purpose, middle details the process in an ordered list-like manner, last states output. No redundancy, every sentence adds information, and the most important info (purpose) is front-loaded.

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 complex (multiple fallbacks, parallel requests), and the description covers the methodology well while the output schema handles return details. Missing a note on failure behavior or expected latency, but given the output schema and clear process, it's nearly complete.

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 coverage is 0%, so the description must compensate. It does: the first sentence specifies 'article URL', giving the single `url` parameter clear semantic meaning. It doesn't dictate format, but for a single-string parameter this is sufficient.

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 opens with a specific verb ('Remove') and resource ('paywall') and immediately distinguishes itself from sibling tools like search_archives or get_from_archive by stating the goal is paywall removal. It further clarifies it works through internet archives, making the tool's scope unambiguous.

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 clearly implies when to use this tool: when a paywalled article URL needs full content extraction. It details the multi-step fallback strategy, but does not explicitly compare with sibling tools or state exclusions (e.g., when not to use), so it stops short of a 5.

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