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

Annotations already declare readOnlyHint and openWorldHint, so the safety profile is partly covered. The description adds genuine value beyond that by disclosing that the returned content is third-party, unaudited, and must be treated as inert text rather than instructions — an important prompt-injection caution for a tool returning raw Solidity. It stops short of noting response size or that retrieval is by id only.

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?

Two compact sentences, front-loaded with what the tool returns, followed by the trust caveat. Nothing is redundant and no sentence is filler.

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-parameter read-only tool with no output schema, the description covers both what comes back (rules and full Solidity) and the trust posture of that content. The only meaningful gap is that alternatives for a narrower or summarized lookup are not mentioned.

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 hook_id parameter is documented in the schema as coming from list_launches. The description adds no further meaning about the identifier format or what happens on an unknown id, so the schema carries the full burden and 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?

The description states a concrete verb+resource: it retrieves a published hook together with its rules and full Solidity source, and it pins the origin (askhook.fun). That is specific enough to distinguish it from a state-reading sibling, though the verb itself is only carried by the title rather than the description body.

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?

The phrase 'for reference or remixing' implies the intended use case, but there is no explicit when-to-use or when-not-to-use guidance and no named alternative such as inspect_hook or get_template for cases where only a summary is wanted. Usage is inferred rather than stated.

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