icp_to_cycles

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

With no annotations, the description carries the full burden. It discloses the current exchange rate and canister creation, but omits key behaviors such as irreversibility, what happens to the new canister, fees, prerequisites (e.g., login/balance), or any failure modes.

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, front-loaded with the primary action, and contains no fluff or redundant information. It earns its place efficiently.

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 significant side effects (creating a canister) and no output schema. The description fails to mention prerequisites, what the user gets back (e.g., canister ID, cycles amount), or any implications of the conversion, leaving a clear gap for such a mutation-like tool.

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?

Input schema coverage is 100% and already provides useful descriptions for both parameters. The description adds no additional parameter-specific meaning, so it defaults to the baseline of 3.

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 action ('Convert ICP to cycles') and the mechanism ('by creating a new canister'), distinguishing it from sibling tools like icp_cycles_balance or icp_top_up_canister. However, it does not explicitly name alternatives, so it stops short of a 5.

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 is given on when to use this tool vs alternatives. The phrase 'by creating a new canister' implies it is for new canisters, but there is no clear when/when-not or comparison with tools like icp_top_up_canister.

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