algorand_get_quote

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

With no annotations, the description must carry the full behavioral burden. It discloses cost and the session prerequisite, which is valuable. However, it does not describe error behavior, idempotence, or whether the session token is consumed. For a simple getter, this is adequate but not fully transparent.

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?

Three short sentences with all information (purpose, prerequisite, cost) front-loaded. No redundant words.

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?

The tool has two required parameters and an output schema, so return values are covered. The description covers purpose, prerequisite, and cost. Missing error-handling details but overall complete for a simple quote tool. Sibling context is clear.

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%, so the description must compensate. It explains session_token via the prerequisite but provides no detail on symbol format or examples. The description adds minimal meaning beyond parameter names.

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 clearly states the tool's function with a specific verb ('Get real-time crypto price quote') and resource ('Algorand x402'), distinguishing it from sibling quote tools like 'get_quote' and 'rh_crypto_quote' through the platform reference and session requirement.

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 explicitly identifies a prerequisite ('Requires valid session from algorand_verify_payment'), indicating the correct sequence of tool calls. It doesn't mention alternatives, but the context is clear enough for an agent to know when to use this tool.

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