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

Annotations already cover readOnly and idempotency, but the description adds real behavioral context beyond them: long documents are split into pages and a 'page' argument continues the read. It says nothing about the shape or size of the returned content, which would have made it a 5.

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?

Three tight sentences, front-loaded with the purpose, followed by parameter provenance and pagination behavior — every sentence carries information and none repeats the schema.

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 read-only retrieval tool with no output schema and fully documented parameters, the description covers provenance and pagination, which is what an agent needs to call it correctly. Only the return-content expectations (format/truncation beyond paging) are left unstated, a minor gap.

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 100%, so the baseline is 3, but the description adds meaning the schema doesn't: that 'page' exists because long documents are paged and is used to continue an in-progress read, and that 'path' values originate from sibling listing tools.

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?

States a specific verb+resource ('Read a full documentation file from a Laravilt package') and supplies a concrete call example with package/path, so an agent can distinguish this from sibling tools like get-package or list-docs immediately.

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?

Explicitly tells the agent where the required 'path' and 'package' values come from (search-docs, list-docs, get-package), which is strong routing guidance. It stops short of stating when this tool should be preferred over the guide-style siblings, so it's clear context without full alternatives coverage.

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