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 discloses meaningful traits: six-hour duration, price-band persistence, eviction when leaving the band, ticker exclusion for old coins, and explicit non-actions ('No fill size. No exit. Does not sign.'). This is strong behavioral context, though it still does not clarify whether the tool itself is read-only or has side effects.

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 text is short and every sentence contributes a rule, but it is written as telegraphic fragments rather than a structured, front-loaded description. 'High-conviction book.' is a weak lead-in and the flow of rules is cryptic, so conciseness comes at the cost of clarity.

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?

Given no annotations, no output schema, and no parameters, the description must fully explain what the tool does and returns. It provides rich rule details but omits the core operation, return value, and relationship to sibling tools, leaving an agent unable to confidently select and invoke it.

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 input schema has zero parameters, so there is no parameter ambiguity to resolve; the baseline of 4 applies. The description's domain words like 'contract', 'coins', and 'LP' are contextual rather than parameter definitions, which is fine since no parameters exist.

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 resource ('High-conviction book') and gives substantive rules about what stays in it, so it is not a tautology. However, it never states a verb or operation—there is no 'get', 'list', 'update', or 'alert'—leaving it ambiguous whether this tool returns the book, monitors it, or applies these rules.

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 explicit guidance about when to use this tool versus the many talon_* siblings. The inclusion criteria imply a domain, but the description does not state conditions such as 'use when you need high-conviction book entries' or name any alternative it should be preferred over.

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