confirmNewRiskLimit

Destructive

Confirm the new maintenance margin rate after Bybit changes a risk limit, releasing the position from reduce-only status.

Instructions

Confirm the pending maintenance margin rate update for a position. This removes the reduce-only restriction that was applied when Bybit adjusted the risk limit.

Agent hint: Use this when a position has isReduceOnly=true due to a risk limit adjustment by Bybit. Calling this confirms the new MMR and removes the reduce-only restriction. Check isReduceOnly in getPositionInfo to determine if this action is needed.

TDQS

A4.1/5.0
Behavior4/5

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

Beyond the destructiveHint and readOnlyHint annotations, the description discloses the mechanism: it confirms the new MMR and lifts the reduce-only restriction. It does not spell out irreversibility or other side effects, but the confirm parameter schema covers user-consent requirements, and the annotations already flag destructiveness.

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

Conciseness3/5

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

The purpose is front-loaded and the agent hint is actionable, but the hint repeats 'confirms the new MMR and removes the reduce-only restriction' already stated in the opening. This redundancy could be trimmed without losing information.

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

Completeness4/5

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

For a single-purpose state-confirmation action, the description provides the trigger condition, the affected state, and the diagnostic step. It lacks return/error details, but there is no output schema, and the confirm parameter plus annotations already cover the user-consent and destructive aspects.

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 coverage is only 33% and the tool description does not explain how symbol or category should be populated; it only implies they identify the affected position. The confirm boolean is well documented in the schema, but the description does not compensate for the undocumented parameters.

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?

States a specific verb ('Confirm'), a precise object ('pending maintenance margin rate update for a position'), and the actionable consequence ('removes the reduce-only restriction'). This clearly separates it from generic confirm tools like confirmQuote and read-only position tools.

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

Usage Guidelines5/5

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

Explicitly tells the agent when to invoke: when a position has isReduceOnly=true due to a Bybit risk-limit adjustment, and tells it to check getPositionInfo to detect that condition. No alternative confirmation tool competes for this scenario, so the absence of an exclusion list is not a gap.

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