arc72_transfer_txn

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

With no annotations, the description carries the behavioral burden. It explicitly states 'Simulate,' indicating non-execution, and specifies the signer requirement, which are key safety and context details. It does not explain return values or side effects further, but covers the most critical behaviors.

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 short sentences, front-loaded with the core action, and every word adds value. No filler or redundant repetition of schema details.

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 lack of an output schema, the description does not explain what the simulation returns (e.g., transaction object, success status, error details). It provides a high-level purpose but leaves a gap in understanding the tool's output behavior, making it minimally viable but not fully complete.

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 schema covers 100% of parameters, but the description adds meaning beyond the schema by clarifying the relationship between 'sender' and 'from' (sender must be the owner or approved operator). This helps the agent understand authorization without relying solely on field descriptions.

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 simulates ARC-72 transferFrom(from, to, tokenId), using a specific verb and resource. It distinguishes from sibling tools by naming the exact function and clarifies the signer role.

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 implies when to use this tool: to simulate a transferFrom transaction, and clarifies authorization (sender must be owner or approved operator). However, it does not explicitly mention alternatives or exclusion cases like when to use approval tools instead.

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