execute_intent

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

There are no annotations, so the description carries the full burden. It discloses the key behavior (signing and sending a transaction to the blockchain) but does not mention consequences such as irreversibility, gas costs, or required prerequisites. The description is concise but lacks additional behavioral context that would help an agent assess the impact.

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 two sentences, both front-loaded with essential information. The first sentence states the purpose, the second provides usage guidance. There is no redundant or filler content; every word earns 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?

Given the absence of annotations and output schema, the description is fairly complete for a simple execution tool. It explains what it does and when to use it, and the parameter schema covers the inputs. It does not describe return values or downstream effects, but these are not critical for correct invocation.

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%, with both parameters well-described in the schema. The description adds value by clarifying that the 'intent' comes from deposit/withdraw tools, linking the parameter to the sibling tools and usage flow. This goes slightly beyond the schema's generic 'blueprint tools' phrasing.

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: 'Executes an intent by signing and sending the transaction to the blockchain.' It names a specific verb and resource (executing an intent) and distinguishes from sibling deposit/withdraw tools by explicitly stating it is used after receiving an intent from them.

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 description provides explicit guidance on when to use the tool: 'Use this after receiving an intent from deposit/withdraw tools.' It gives clear context and sequencing, though it does not name explicit alternatives or exclusions beyond this. The mention of deposit/withdraw tools implies the alternative (using those tools to create intents).

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