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

Annotations already declare this a safe, idempotent, closed read (readOnlyHint=true, idempotentHint=true, destructiveHint=false, openWorldHint=false), so the safety profile is covered. The description adds value by characterising the result as a lightweight summary listing rather than full strategy detail, but says nothing about completeness, ordering, or pagination.

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?

A single tight sentence that front-loads the resource before the field list, with no filler. It is slightly under-specified rather than padded, which is a mild fault on this dimension.

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 explaining returns, and it does name the four fields an agent will receive. For a zero-argument, read-only list tool this is close to sufficient; only ordering, volume, and pagination behaviour are unstated.

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 baseline is 4 by rule. There is no parameter semantics for the description to clarify or omit.

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 precisely — the public rule set that ALK signals derive from — and enumerates the fields returned (id, name, badge, summary). It reads as a noun phrase rather than an explicit 'list' action, and it does not distinguish itself from siblings like explain_strategy or get_signals, but the resource is unambiguous.

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 indication of when to call this versus explain_strategy, get_signals, or get_backtest, and no prerequisites or exclusions are stated. An agent must infer from the name alone that this is the entry-point enumeration tool.

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