Guard Trailing Stop

What it does

When your agent uses it

• Protecting an open position
• Setting trailing stops
• Automating profit-locked exits

Example prompts

• “/guard-trailing-stop”

Requirements

• Python 3
• Compatibility (from SKILL.md): Requires python3 and yex-trader (agent-cli) installed. Hyperliquid perp positions. Direct HL API — no mcporter needed.

Workflow steps

2 steps, taken from the step headings in SKILL.md.

1. 1"Let It Breathe"
2. 2"Lock the Bag"

What it can do on your machine

Read from SKILL.md and the folder at commit 58619a2. It shows what the files ask for, not the result of running them.

• Tool permissions

  Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

  From allowed-tools in the SKILL.md frontmatter.

• Runs code

  Ships 1 file in scripts/ (Python), which the agent can run.

  From the folder's file list and the shell code blocks in SKILL.md.

• Network

  No URLs in SKILL.md.

  From URLs in SKILL.md, links to its own repository left out.

• Credentials

  Names no API keys, tokens, secrets or passwords.

  From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

• Compatibility

  Requires python3 and yex-trader (agent-cli) installed. Hyperliquid perp positions. Direct HL API — no mcporter needed.

  From compatibility in the SKILL.md frontmatter.

Context cost

Guard Trailing Stop loads about 1.9k tokens when it runs. Until then it costs about 113 tokens; SKILL.md has 708 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it

~113

When it runs · the whole SKILL.md, loaded when a task matches

~1.9k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

description

Guard — two-phase ROE-based trailing stop system for Hyperliquid perps. Phase 1 lets the trade breathe with wide retrace and patient breach counting. Phase 2 locks profit through configurable tier ratcheting with per-tier retrace overrides. Supports LONG and SHORT, hard/soft breach decay, stagnation take-profit, and preset configs. Use when protecting an open position, setting trailing stops, or automating profit-locked exits.

compatibility

Requires python3 and yex-trader (agent-cli) installed. Hyperliquid perp positions. Direct HL API — no mcporter needed.
