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

With no annotations, the description carries the full burden. It does disclose two real behavioral traits — output is full page text rendered as Markdown and images are stripped — but says nothing about truncation, pagination, permissions, or rate limits, even though the max_chars parameter implies output can be cut short.

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 compact sentences: the first states what comes back, the second tells the agent exactly what to supply, with examples. Nothing is padded, though the return-format sentence leads rather than the purpose, which slightly buries the verb.

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?

For a two-parameter read tool with no annotations and no output schema, the description covers the essentials: what is returned, in what format, and what input to give. It still omits what happens when max_chars is exceeded and whether the page must first be discovered via list_orlandu_pages, which matters given zero structured behavioral coverage.

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 only 50%, and max_chars has no description anywhere, so the description has to compensate — and it does for the required parameter by giving concrete accepted forms ('pvm-20l5-buying-guide' or a full https URL) that go beyond the schema's terse 'Slug or URL'. The truncation semantics of max_chars remain unexplained, keeping it out of 5 territory.

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 verb+resource ('The full readable text of one orlandu.com page') and pins the output format ('as Markdown (no images)'). The word 'one' implicitly contrasts with the list/search siblings, but no sibling is named explicitly, so it falls short of 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 only implied: the request for a slug or URL signals 'use this when you already know which page you want,' which distinguishes it in spirit from list_orlandu_pages and search_orlandu. There is no explicit when-to-use, when-not-to-use, or named alternative, so it stays at implied guidance.

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