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 adds genuine value by disclosing that source code is NOT included here (retrieve it via get_template) and that Montra templates are set up elsewhere, but it says nothing about pagination, result size, or freshness of the template catalog.

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 tight sentences with no filler, and the category split is front-loaded so an agent learns the two template types immediately. The lead phrase 'AskHook's tested templates' is mildly redundant with the title, a minor waste in an otherwise efficient definition.

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?

With no output schema, the description carries the burden of conveying what a caller gets back, and it never describes the shape of a template entry (name, id, flags, launch association). It does orient the agent on the two template families and where full details live, which is adequate but leaves a notable gap for a discovery tool.

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?

The tool takes zero parameters, so the schema leaves nothing to explain and the baseline of 4 applies. The description correctly spends no words on parameters and instead uses the space for domain context.

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 identifies the resource concretely and splits it into two named categories (own-pool Uniswap v4 hook templates vs. Montra templates), which an agent could not infer from the name alone. The verb 'list' lives only in the name/title, and the opening sentence ('AskHook's tested templates') is a noun phrase rather than an explicit statement of what is returned, so it falls short of a 5.

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 gives useful routing context by naming get_template as the way to fetch full source for hook templates, and it signals that Montra templates are configured in the AskHook app rather than here. It does not address when to prefer this over siblings like list_chain_hooks or trending_hooks, nor does it state any preconditions, so guidance is implied rather than explicit.

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