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

With no annotations, the description carries the full burden. It does disclose a key behavioral trait: the operation costs $5.00 USDC and takes place on Solana Mainnet, which signals a paid, real-funds action. However, it does not mention whether the operation is irreversible, whether it requires existing accounts or wallet funds, or what happens on failure.

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?

A single sentence front-loads the action and resource types, includes the cost, and contains no filler. Every element 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?

The tool has no output schema, no annotations, and an undocumented nested params object. The description leaves critical gaps: an agent cannot know what to pass in 'params', what the return value is, or how to handle errors. The cost and network info are helpful but insufficient.

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%, and the description only echoes the contractType enum values without adding operational meaning. The required nested 'params' object is completely unexplained, leaving the agent unable to construct a valid invocation.

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 states a specific verb ('initializes') with discrete resource types (SPL Escrows, cNFT Badge Issuers, Raydium Vaults) and a clear network scope (Solana Mainnet). This distinguishes it from the generic sibling deploy_contract and other tools like smart_contract_verifier.

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 specific contract types imply when to use the tool, but the description never explicitly contrasts it with alternatives like deploy_contract or states when not to use it. Usage context is clear, but no when-not or alternative routing is provided.

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