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

No annotations are provided, so the description carries the full behavioral burden. It reveals the comparison inputs and a decision rule, but it is ambiguous whether the tool only reports a premium signal or actually executes the acquisition; the imperative 'acquire' could be interpreted as an instruction to the agent or as the tool performing a trade.

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 only two short sentences, with the core comparison front-loaded and no filler. Every phrase contributes to explaining the tool's purpose or the resulting decision rule.

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?

The tool has one simple parameter, no output schema, and no annotations, so the description does most of the work. It conveys the core signal and an action rule, but it leaves undefined what output shape the agent should expect, what threshold counts as 'high', and whether the tool has side effects.

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%, but there is only one parameter named 'symbol'. The description's domain language ('stock', 'RHJ') weakly implies that symbol is a stock ticker, but it never explicitly defines the expected symbol format or meaning, so it only minimally compensates for the missing schema description.

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 a clear comparison object: AMM price versus official RHJ true bid/ask, and gives a conditional action rule. It does not use an explicit verb like 'returns' or 'calculates', and it does not name any sibling to distinguish from, so it stops 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?

The second sentence supplies a practical rule: if premium is high, acquire via Rialto (propAMM) not the AMM. This implies the tool's purpose but does not explicitly say when to invoke this tool versus other talon_* tools, nor define what 'high' means.

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