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

Annotations already declare readOnlyHint, idempotentHint, openWorldHint and destructiveHint=false, so safety is covered structurally. The description adds that content is the desk's own published/checked coverage, but says nothing about freshness guarantees or rate behavior beyond what the schema's max_age_s already states.

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?

Purpose and usage are front-loaded and tight, which is good. However, the trailing 'Args:' list is redundant with the schema and misleadingly partial, so it does not earn its place.

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 and 7 optional params, the description adequately frames selection but leaves the account view's dependency (wallet required, dex scoping, staleness) entirely to the schema. It also never routes the agent away from the several close perps siblings.

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 100%, so the schema already documents every parameter in detail, including the view enum and dex scoping. The description's 'Args: view; market; trader; wallet; limit' adds no meaning and is actually incomplete, omitting dex and max_age_s.

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 names a specific resource — OptimistFi's perps desk — and itemizes its three content sets (stories, traders directory with checked calls, covered Hyperliquid wallets). That is much clearer than the sibling names like get_perps or get_perps_history, though it never explicitly distinguishes itself from those close siblings.

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 concrete triggering questions ('latest perps news on X', 'is trader Y worth following'), which maps user intent to usage well. It offers no when-not conditions and does not tell the agent when to prefer get_perps, get_perps_market, or get_perps_history over this desk view.

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