zap1_verify_evm

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

No annotations provided, so description must fully convey behavior. It states verification via contract but does not clarify whether it's a read or write operation, gas implications, error handling, or side effects. Insufficient for an on-chain interaction.

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?

Two sentences, highly concise, front-loaded with the primary action and supported chains. No wasted 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?

No output schema, so description should explain return values or success/failure indicators. It does not mention what the tool returns (e.g., boolean or transaction hash) or behavior on verification failure. Missing contract addresses or references.

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?

All 5 parameters have schema descriptions (100% coverage). Description adds context about Zcash anchor roots and chains but does not add significant meaning beyond schema for individual params. Adequate but not exceptional.

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?

Description specifies the tool verifies a ZAP1 Merkle proof on-chain, checks leaf hash inclusion in a Zcash anchor root, and lists supported chains (Sepolia, Base, Arbitrum). Clearly distinguishes from siblings like verify_proof and zap1_prove_receipt.

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?

No explicit guidance on when to use this tool versus alternatives, such as off-chain verification or other chain-specific tools. Missing when-not-to-use or contextual prerequisites.

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