addMargin

Destructive

Add additional collateral to a leveraged liquidity mining position to prevent liquidation. Requires explicit user confirmation before execution.

Instructions

Add additional collateral (margin) to a leveraged Liquidity Mining position to avoid liquidation.

Rate Limit: 5 req/s (UID)

Agent hint: IMPORTANT: This adds real collateral to an existing liquidity mining position. Before executing, you MUST ask the user to explicitly confirm the position ID and margin amount. Do not execute automatically.

TDQS

A3.9/5.0
Behavior4/5

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

Annotations already mark destructiveHint: true and readOnlyHint: false. The description adds valuable safety context by warning that this adds real collateral to an existing position and requires explicit user confirmation. The rate limit note is also useful. It does not detail other side effects, but it goes beyond the structured annotations.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is concise and front-loaded: a clear one-sentence function, a rate-limit note, and a critical safety hint. Every sentence adds operational value and there is no filler.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

This is a high-stakes, destructive mutation with 6 required parameters, no output schema, and very low schema description coverage. The description covers purpose, rate limit, and user confirmation well, but does not explain several required parameters or what the API returns, leaving an agent under-equipped for fully correct invocation.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters2/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is only 17%, and the description only references 'position ID and margin amount' (positionId and amount). It leaves productId, orderLinkId, and quoteAccountType unexplained, and does not specify amount format or how orderLinkId should be generated. The confirm flag's semantics are covered by the schema, not the description.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description states a specific verb and resource: 'Add additional collateral (margin) to a leveraged Liquidity Mining position to avoid liquidation.' This clearly identifies the operation and its purpose, and distinguishes it from related siblings like addLiquidity or removeLiquidity.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The purpose clause 'to avoid liquidation' gives clear usage context, and the agent hint explicitly says not to execute automatically and to require user confirmation of position ID and margin amount. However, it does not explicitly contrast this tool with similar margin-related alternatives like addReduceMargin or setAutoAddMargin.

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