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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and openWorldHint=false, so the safety profile is covered. The description adds genuine context beyond them: the hard 6-page read cap and the 1-based page indexing, both of which affect how an agent should slice large reads; it stops short of saying whether an oversized count errors or is clamped, or what an out-of-range page yields.

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 sentence with zero filler; the two operative constraints (max 6, 1-based) are packed into the parameter references rather than padded with extra prose.

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?

Return values are covered by the output schema and safety by annotations, so the description need only handle inputs and behavior. It leaves two agent-relevant gaps: the format of the required 'file' argument and what happens on out-of-range pages or counts above 6.

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 the parameter load. It usefully documents 'page' as 1-based and 'count' as capped at 6 (a limit the schema itself does not encode, since count has only a default of 2), but the required 'file' parameter is left completely unexplained — no indication whether it is a path, name, or ID.

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 and resource ('Read the text of ... pages of a file') plus the scope limits (max 6, 1-based start). It never names or distinguishes itself from siblings such as get_contents or page_image, so an agent must infer that this one returns page text rather than a page image or a table of contents.

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 word 'text' and the max-6 cap hint that this is the bulk-text reader rather than the image or search tools, but there is no explicit when-to-use statement, no exclusion, and no named alternative.

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