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

Annotations already cover safety (readOnly, idempotent, non-destructive, closed-world), so the description earns credit for the additive part: the 'public' qualifier tells the agent private strategies will not be returned, and it names the four payload components in the absence of an output schema. It does not say what happens when the slug does not resolve or refers to a private strategy.

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 front-loaded sentence with the return payload enumerated in a compact list. No filler, no restatement of the title.

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?

Reasonable for a one-parameter read: payload composition and the public-only constraint are stated despite no output schema. However, the required slug is left entirely undefined and the not-found/private-access behavior is absent, which an agent needs in order to retry or fall back to search.

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% for the single parameter, so the description must compensate and it does not: the word 'slug' never appears and no format, source (e.g. from list_strategies) or casing rules are given. The only hint is the singular 'one ... strategy' framing.

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?

Specific verb+resource ('Returns one public Hub strategy') with an enumeration of what the record contains (spec, backtest result, forward-tracking, fork lineage). The word 'one' distinguishes it from the bulk sibling list_strategies, though no sibling is named explicitly.

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?

Usage is only implied by 'one public Hub strategy' – an agent can infer this is a single-record lookup keyed by slug. There is no explicit when-to-use or when-not (e.g. list_strategies for browsing, fork_strategy/publish_strategy for mutations), and no prerequisites stated.

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