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

Annotations already signal a mutating, non-idempotent operation; the description adds that it costs $5.00 USDC and targets mainnet, which is useful real-world context. It does not disclose side effects, reversibility, or prerequisites (e.g., funded accounts), but there is no contradiction with annotations.

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?

One sentence with no filler, front-loading the action, resource, and platform before the parenthetical cost. 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?

Despite an output schema and annotations, this is a paid, state-changing deployment tool with a nested parameters object; the one-sentence description leaves out what each contract type requires inside 'params', any account/funding prerequisites, and what 'initializes' implies operationally. An agent invoking it correctly would need more context.

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 already documents both parameters, including the contractType enum, so the description needs to add little here. The description does map enum values to domain terms, but it does not explain the nested 'params' object contents, which remains vague.

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 names a specific action ('initializes') and concrete resources ('SPL Escrows, cNFT Badge Issuers, or Raydium Vaults') on a specific network ('Solana Mainnet'), so an agent can tell what it does. It does not explicitly contrast with sibling deploy_contract or deploy_arc_contract, so it stops short of full sibling differentiation.

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 use case is implied by 'Solana Mainnet' and the three contract types, so an agent can infer when this tool applies. However, there is no explicit 'use when' guidance, no mention of when to prefer deploy_contract/deploy_arc_contract instead, and no exclusions.

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