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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and closed-world scope, so the safety profile is fully covered. The description adds the useful semantic note that footnotes are the editor's notes rather than the author's words, but the rest is return-shape detail already implied by the output schema.

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?

Front-loads the core action ('Read one library page by the id...') before the return details, with no filler sentences. The second sentence is long and packs several metadata items, but each earns its place as interpretive context.

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 single-page read tool with a full param schema, annotations, and an output schema, the description covers the essential concerns: where the id comes from and how the returned text/footnotes are organized. Nothing critical to correct invocation is missing, though sibling disambiguation could be stronger.

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% and the single `id` parameter is fully documented there. The description reinforces the "{bookId}:{pageId}" format and its provenance from `search`, which is marginal added value over the schema, so baseline 3 applies.

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 (Read) and resource (one library page), and even gives the id shape "{bookId}:{pageId}". It ties itself to the `search` sibling that produces the id, so an agent can distinguish this retrieval tool from the many search_* siblings without opening a schema.

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?

It implies usage by telling the agent the id comes from `search`, which is genuine routing guidance. However, it offers no explicit when-not or comparison against near-neighbors like shamela_get_page, shamela_get_pages_range, or shamela_get_book_section, so the agent must infer when this is the right retrieval tool.

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