Investigate how a concept, code path, application, network flow, system, incident, document, or local artifact actually works, then deliver a two-depth visual HTML explainer with a dead-simple big-picture first layer and source-backed technical depth behind it. Use when the user invokes $xray, asks how something works under the hood, wants a module or app behavior traced across boundaries, requests web, code, network, or safe static artifact research before explanation, or asks for an…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# X-Ray Explainer Investigate first and explain second. The HTML is a projection of verified understanding, not decoration around an early guess. ## Operating Boundary - Directly perform read-only research, repository inspection, log/config examination, source archaeology, and creation of the requested explainer artifact. - When the user asks to analyze a clearly identified app, CLI, or local compiled artifact they are entitled to inspect, include safe read-only static inspection when it can answer the teaching question. Record identity and hash first; inspect metadata, signatures, dependencies, imports, recoverable symbols, strings, entitlements, and bundled resources without modifying or executing the target. - For an authorized native binary or compiled CLI, load `$claude-code-reverse` first and use its tested `extract.sh` workflow as the canonical identity, hash, cache, and safe static baseline. Do not duplicate that baseline inside X-Ray. …

How to install
mdr add majiayu000/spellbook/xray@sha256:fda1f3da20b2c060The line at the top of this page pins the label git:20260830.fc5a631, 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.
