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

Annotations already declare readOnlyHint=true and openWorldHint=true, so the safety profile is covered. The description does add genuine caveats beyond the annotations: 'named only while listed; never a creator account' and 'declared callbacks (not a safety verdict)'. These are useful scope limiters, though the phrasing is cramped and omits other operational behavior.

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?

The description is a single run-on fragment with nested parentheticals and no front-loaded statement of what the tool does. Several clauses are backward or ambiguous, so the content does not read cleanly despite being short.

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?

An output schema exists, so return values need not be spelled out, yet the description spends its text enumerating returns while omitting input semantics and usage context. It is adequate for a simple single-parameter lookup but leaves the agent guessing about scope and alternatives.

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% and the description never mentions the required address parameter or what it should point at. The single parameter is largely self-evident from the tool name and the address regex pattern, which keeps this at a minimum-viable 3 rather than lower.

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 name and title identify the resource (a Uniswap v4 hook) and the description enumerates the content returned (creator/project tie, declared callbacks, source, hooklist entry, pools by week, unknowns). However, it is phrased as a question with no clear verb, and the extraneous 'Robinhood Chain' framing muddies the scope rather than clarifying it. The purpose is inferable but not stated cleanly.

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?

There is no statement of when to use this tool, when not to, or how it relates to siblings like get_contract or get_project_timeline. The reader must guess that this is the hook-specific lookup versus the generic contract lookup.

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