90 / 100 · Low risk

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

Break down Claude Code costs using the Agent Monitor pricing engine. Shows per-model costs (input, output, cache_read, cache_write at $/Mtok rates), per-session costs, daily trends, and compaction baseline token recovery. Use when analyzing spending, comparing model costs, or planning budgets.

Works with any agent that supports SKILL.md skills.

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

if [ -e ~/.agents/skills/'cost-breakdown' ] || [ -L ~/.agents/skills/'cost-breakdown' ]; then echo 'A skill folder named cost-breakdown already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/hoangsonww/Claude-Code-Agent-Monitor' "$d" && git -C "$d" checkout --quiet 'a46ad70f2715bd5f59634397f3e92dec71758492' -- 'plugins/ccam-analytics/skills/cost-breakdown' && mkdir -p ~/.agents/skills && cp -R "$d"/'plugins/ccam-analytics/skills/cost-breakdown' ~/.agents/skills/'cost-breakdown' && 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/'cost-breakdown' ~/.claude/skills/'cost-breakdown' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
