What Truth Shield does

Stop Claude from lying to you. A Claude Code skill that fact-checks every claim against real sources — code files, live docs, web search — and flags anything it can't confirm.

Truth Shield in action

Install (30 seconds)

**Mac / Linux**

curl -sfL https://raw.githubusercontent.com/BAS-More/truth-shield/master/install.sh | bash

**Windows (PowerShell)**

irm https://raw.githubusercontent.com/BAS-More/truth-shield/master/install.ps1 | iex

[!TIP] Add `TRUTH_SHIELD_HOOK=yes` before the install command to also install the **always-on enforcement hook** — a deterministic gate that runs outside Claude's context window and cannot be prompt-injected.
