Check before installing. Some of what it can do is expected: a coding skill usually runs build and test commands.

Generate complete, installable OpenClaw trading skills from natural language strategy descriptions. Use when your human wants to create a new trading strategy, build a bot, generate a skill, automate a trade idea, turn a tweet into a strategy, or asks "build me a skill that...". Produces a full skill folder (SKILL.md + Python script + config) ready to install and run.

Works with any agent that supports SKILL.md skills.

Install

Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.

if [ -e ~/.agents/skills/'simmer-skill-builder' ] || [ -L ~/.agents/skills/'simmer-skill-builder' ]; then echo 'A skill folder named simmer-skill-builder already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/SpartanLabsXyz/simmer-sdk' "$d" && git -C "$d" checkout --quiet 'bb9effd502917cdf64eeb21604add3b7c10ac0c3' -- 'skills/simmer-skill-builder' && mkdir -p ~/.agents/skills && cp -R "$d"/'skills/simmer-skill-builder' ~/.agents/skills/'simmer-skill-builder' && rm -rf "$d"; fi

Codex reads ~/.agents/skills directly. For Claude Code, Cursor, Copilot, Gemini CLI, Antigravity or OpenCode, also link it. For Claude Code: ln -s ~/.agents/skills/'simmer-skill-builder' ~/.claude/skills/'simmer-skill-builder' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
