llm-cost-optimizer

100 / 100 · Low risk

Fine to try.

By alirezarezvani/claude-skills (GitHub) · coding · 29,783 stars · scanned at commit 08cd8a9

Use whenever an LLM feature is being built or its costs come up (model choice, prompt caching, token limits, per-feature spend). Sets routing, caching, max_tokens and cost logging before launch rather than after the bill.

Works with any agent that supports SKILL.md skills.

What this skill can do

We found nothing in the files we read that matches our rules. That does not prove the skill is safe: see the limits of static scanning.

Install

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

if [ -e ~/.agents/skills/'llm-cost-optimizer' ] || [ -L ~/.agents/skills/'llm-cost-optimizer' ]; then echo 'A skill folder named llm-cost-optimizer already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/alirezarezvani/claude-skills' "$d" && git -C "$d" checkout --quiet '08cd8a9fc86cc370e2c0d448e8171fbcfdbc5a30' -- 'engineering/llm-cost-optimizer/skills/llm-cost-optimizer' && mkdir -p ~/.agents/skills && cp -R "$d"/'engineering/llm-cost-optimizer/skills/llm-cost-optimizer' ~/.agents/skills/'llm-cost-optimizer' && 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/'llm-cost-optimizer' ~/.claude/skills/'llm-cost-optimizer' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
