execute_swap

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

No annotations are provided, so the description must convey behavioral traits. It only mentions the private key requirement, but fails to disclose destructive nature, on-chain state changes, fee implications, or error behaviors. This is insufficient for a token swap execution.

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?

The description is concise with two sentences, no wasted words. However, it is slightly too brief and could benefit from a bit more context without harming conciseness. Front-loading is adequate.

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?

Given the tool's complexity (executing a swap on a DEX), the description lacks return value information, no mention of gas fees or confirmation requirements, and provides no output schema. It is incomplete for an agent to understand the full behavior.

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 input schema has 100% description coverage with clear explanations for each parameter (e.g., input_mint, amount, slippage_bps with default, network with enum). The description adds no extra parameter information beyond requiring a private key, so it meets the baseline.

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 executes a token swap on Jupiter DEX aggregator, using a specific verb and resource. It is distinct from the sibling 'get_swap_quote' which likely provides quotes, making the purpose 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?

The only guidance is 'Requires PRIVATE_KEY.' There is no information on when to use this tool versus alternatives like get_swap_quote, no conditions for use, and no mention of prerequisites beyond the key.

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