Fine to try. Some of what it can do is expected: a coding skill usually runs build and test commands.

Autonomous cloud-cost analyst across Neon, Vercel, Railway and GitHub Actions - pulls per-object usage, attributes it to the biggest drivers, root-causes each, and emits recommendations ranked by real signal (idle %, over-allowance, failure rate) with dollar figures only where the billing API returns real ones (and, armed, applies safe cost levers).

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/'spend-watch' ] || [ -L ~/.agents/skills/'spend-watch' ]; then echo 'A skill folder named spend-watch already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/aeonfun/aeon' "$d" && git -C "$d" checkout --quiet '5981e1caa880e9bc186e1bf9f27c095b3ba9ef22' -- 'skills/spend-watch' && mkdir -p ~/.agents/skills && cp -R "$d"/'skills/spend-watch' ~/.agents/skills/'spend-watch' && 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/'spend-watch' ~/.claude/skills/'spend-watch' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
