cache-efficiency

90 / 100 · Low risk

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

Analyze prompt-cache effectiveness for Claude Code usage from the Agent Monitor dashboard — cache hit rate (total_cache_read / (total_cache_read + total_input)), cache_write vs cache_read reuse, cache-read vs cache-write spend, and the sessions with the poorest reuse. Pulls token totals from /api/analytics, per-session detail from /api/sessions, and dollar splits from /api/pricing/cost. Use when diagnosing cache spend or deciding whether prompt caching is paying off.

Works with any agent that supports SKILL.md skills.

What this skill can do

Install

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

if [ -e ~/.agents/skills/'cache-efficiency' ] || [ -L ~/.agents/skills/'cache-efficiency' ]; then echo 'A skill folder named cache-efficiency 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 "$d" checkout --quiet 'a46ad70f2715bd5f59634397f3e92dec71758492' -- 'plugins/ccam-analytics/skills/cache-efficiency' && mkdir -p ~/.agents/skills && cp -R "$d"/'plugins/ccam-analytics/skills/cache-efficiency' ~/.agents/skills/'cache-efficiency' && 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/'cache-efficiency' ~/.claude/skills/'cache-efficiency' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
