setTradingStop

Destructive

Set take profit, stop loss, or trailing stop on an open Bybit position. Choose full or partial mode, then confirm to apply or cancel by setting values to zero.

Instructions

Configure trading stop parameters including take profit, stop loss, and trailing stop. Supports both full position and partial position TP/SL modes.

Agent hint: Use this to set TP/SL/trailing stop on an open position. Set tpslMode to Full for entire position or Partial for partial. In Partial mode, tpSize and slSize must be equal. Set any value to "0" to cancel it. positionIdx is required: 0 for one-way mode, 1 for buy hedge, 2 for sell hedge.

A3.8/5.0
Behavior4/5

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

Annotations already signal destructiveness and non-read-only behavior, so the description does not need to restate that. It adds useful behavioral detail such as setting a value to '0' to cancel it and the requirement that tpSize and slSize be equal in Partial mode. 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.

Conciseness4/5

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

The description is reasonably concise and front-loaded with the core purpose before diving into mode-specific guidance. There is minor redundancy between the opening sentence and the agent hint, but every statement generally earns its place.

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

Completeness3/5

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

For a tool with 17 parameters, no output schema, and destructive annotations, the description covers the core usage well but leaves important optional parameters and behavioral edge cases undocumented. An agent could correctly execute a basic stop configuration but would lack guidance for trigger types, limit prices, and advanced trailing-stop behavior.

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

Parameters3/5

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

With schema description coverage at only 6%, the description carries meaningful weight by explaining tpslMode, positionIdx, tpSize/slSize equality, and the cancel-by-zero behavior. However, many parameters such as activePrice, trigger types, order types, and limit prices remain unexplained, so the compensation is partial.

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

Purpose4/5

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

The description clearly identifies the action: configuring trading stop parameters such as take profit, stop loss, and trailing stop on an open position. It is specific and understandable, though it does not explicitly differentiate itself from sibling tools like setLeverage or setPriceLimit.

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 agent hint explicitly says when to use the tool: to set TP/SL/trailing stop on an open position, and explains the Full/Partial mode choice. It provides clear context but does not state exclusions or mention alternative tools for related position-management actions.

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