Audit your Claude Code setup against prompt caching best practices. Checks ordering, tool stability, dynamic content handling, and hook injection patterns. Returns a scored report with specific fixes.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Prompt Cache Audit Skill **Trigger:** `/cache-audit` or "audit my caching" or "check my cache setup" or "am I breaking the cache?" **What it does:** Reads your live Claude Code configuration and checks it against the 6 prompt caching rules from Anthropic's engineering team. Returns a scored report with specific, actionable fixes. **Reference:** Based on Thariq Shihipar's thread "Lessons from Building Claude Code: Prompt Caching Is Everything" --- ## When Invoked Run all checks automatically. Do not ask for confirmation. Read the relevant files and produce the full report in one pass. --- ## The 6 Checks ### Check 1 — Prompt Ordering (Static Before Dynamic) **Read:** `~/.claude/settings.json`, all active `CLAUDE.md` files in the project hierarchy **What to look for:** - Does the system prompt load in the right order? Rule: static content first, dynamic content last - Correct order: System prompt → Tools → CLAUDE.md → Session context → Messages - Flag: Any dynamic content (timestamps, git status, current date, user stats) appearing in the system prompt itself - Flag: CLAUDE.md files that include session-specific or time-sensitive data …

How to install
mdr add pantheon-org/tekhne/cache-audit@sha256:f95a50dda3114a8eThe line at the top of this page pins the label git:20260710.a38941a, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
