Checks what a shipped AI product's system prompt and tool schema actually say by reading a dated public archive instead of recalling them. Use when the user asks what some agent is instructed to do, quotes a system prompt and wants it verified, shows an extracted or leaked prompt, or compares how two products are set up. Read-only; fetches public files from github.com.
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
# System prompt lookup Asked what Cursor's system prompt says, a model will usually answer — fluently, and from nothing. The result reads like a quotation but is a reconstruction. This skill makes the agent stop and go read the artifact. The source is [OrcaPromptVault](https://github.com/Continuum-AI-Corp/OrcaPromptVault): a dated archive of the system prompts and tool-call schemas that shipped AI products send, one directory per product, schemas as JSON, every artifact labelled with how it was obtained — captured off the wire while the product ran unmodified, or reported by the vendor. ## When to Use This Skill - The user asks what a product's system prompt says, or quotes one and asks whether it is real. - You are about to state that some agent "is instructed to" do something. - The user shows an extracted or leaked prompt and wants it verified. - You are comparing products: prompt size, how many tools ship, how a refusal is phrased. - You are writing a harness and want to see how shipped ones solve the same problem. Not for concluding how a product behaves **today**. Every artifact is a dated snapshot of one version on one day. ## What This Skill Does …

How to install
mdr add davepoon/buildwithclaude/system-prompt-lookup@sha256:c701452572653314The line at the top of this page pins the label git:20261010.43b6716, 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.
