Read Access to Insight page

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

Annotations already declare readOnly, idempotent, openWorld and non-destructive, so the safety profile is covered. The description adds two genuinely useful behaviors beyond that: the returned content includes a license notice, and failed fetches fall back to official mirrors. However, it never discloses that content is truncated/paginated — a significant behavior given the limit default of 12000 characters.

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?

A single tight sentence with the resource and accepted input forms front-loaded, followed by two short value-adding clauses about license and mirrors. Nothing is redundant.

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 no output schema, the description does well to mention the license notice in the response, and mirror fallback covers network reliability. But for a fetch tool that paginates long content, the absence of any explanation of limit/offset or truncation leaves an agent unable to predict partial results.

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 0%, so the description must carry parameter meaning. It clarifies that 'path' may also be a URL, which is real added value, but the limit and offset parameters — which control truncation of long pages — are completely unaddressed in both schema and 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 gives a specific verb and resource ('Read an Access to Insight page') and enumerates the content types covered (translation, essay, study guide), so an agent knows exactly what it retrieves. It does not explicitly distinguish itself from siblings like get_text, get_translation, or search_access_to_insight, which keeps it from a 5.

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?

Usage is implied: supply a path or URL to fetch that page. There is no statement of when to prefer this over get_text/get_translation or when not to use it, and no prerequisites are given, so the agent must infer the routing.

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