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

Annotations already declare readOnlyHint=true, destructiveHint=false, and openWorldHint=true, so the safety profile is covered. The description adds nothing behavioral beyond that: no indication of whether the price is realtime or delayed, spot or futures, the quote currency, or any rate/latency behavior for an open-world network call.

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 no filler or repetition. It is efficient, though its brevity borders on under-specification for the questions an agent will actually have.

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?

There is no output schema, so the description carries the burden of describing the return value — it says nothing about the shape of the result (price value, currency, timestamp, source). For a one-parameter open-world market-data tool with an ambiguous data source, this leaves real gaps.

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 coverage is 100% — the single 'symbol' parameter is fully documented with format examples (BTCUSDT) and length constraints. The description reinforces the domain ('crypto or altcoin symbol') but adds no format, casing, or quote-currency detail beyond the schema. Baseline 3 applies.

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?

States a concrete verb ('Get') and resource ('symbol price') with scope covering crypto/altcoin. It is implicitly distinguishable from siblings, which are all CRUD operations on signals, strategies, webhooks, and API configs — nothing else returns market prices. However, it names no sibling or boundary, so full 5 is not earned.

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 when-to-use guidance, no prerequisites, and no alternatives mentioned. The agent is left to infer that this is a live spot-price lookup versus any other price-related capability, and there is no note about which market/exchange the price is drawn from.

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