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

Annotations already declare readOnlyHint=true and openWorldHint=true, so safety and live-data scope are covered. The description adds that results come from a live index and are ordered by pool count, but says nothing about pagination, sorting ties, or what it means for a hook to be 'live' on the chain.

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?

One dense sentence with zero filler, and the scope ('Every ... hook live on Elysium') is front-loaded ahead of the ranking and source clauses. The phrase 'AskHook's live index of the chain' is slightly redundant with 'live on Elysium'.

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?

A simple, fully optional-parameter read tool with readOnly/openWorld annotations covering the safety profile and a complete schema, so little is needed. The one gap is return shape, since there is no output schema and the entry fields (hook address, name, pool count) are not described.

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 both parameters (limit, permission enum) are fully self-documenting, so the baseline is met. The description goes slightly beyond by establishing the ranking dimension that the schema never expresses, though it does not restate the default limit of 20.

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?

Names a specific resource (Uniswap v4 hooks live on Elysium) plus the ordering rule (ranked by pool count) and data source (AskHook's live index). It separates itself from 'trending_hooks' implicitly via the ranking basis, though it never names a sibling explicitly.

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: an agent can infer this is for browsing the hook ecosystem ranked by adoption. There is no explicit when-to-use, when-not-to-use, or pointer to trending_hooks / hook_pools for the alternative view.

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