settle_channel

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

With no annotations provided, the description carries the burden of behavioral disclosure. It does reveal the primary effects (paying the provider, refunding the remainder) and implies the prerequisite that the channel be open. However, it omits important details such as whether the settlement is irreversible, what happens if the channel is not open, or any required permissions.

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 a single, concise sentence that immediately states the action and front-loads the core purpose. Every word adds value, with no redundancy or extraneous information.

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 tool's financial impact and the absence of an output schema or annotations, the description is somewhat thin. It doesn't explain how to discover the channel ID, what the return value is, or whether the action is reversible. For a one-parameter operation, it is minimally adequate but not rich enough for full autonomous decision-making.

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 description provides no information about the channel_id parameter. Since the schema has 0% description coverage and the only parameter is not elaborated, the agent gets no extra meaning about how to obtain or format the channel ID, which is a notable gap even though the parameter name is self-explanatory.

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 ('settle') and the resource ('open micro-payment channel'), and goes further to specify the financial outcomes: paying the provider and refunding the remainder. This distinguishes it from sibling tools like open_channel and consume_channel, making its purpose unambiguous.

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 the usage scenario: settling an open channel. It does not explicitly mention when to use this tool over alternatives like consume_channel or get_channel, nor does it provide exclusions. The context is clear but lacks explicit guidance.

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