# Bullshit Detector

[](https://skills.sh/SerhiiKorniienko/bullshit-detector)

Agent skills that fact-check the internet. Point your agent at a viral YouTube video, article, tweet, or PDF — get a claim-by-claim verification report with sources and a **BS score (0–10)** instead of taking "10 WAYS TO MAKE MONEY WITH AI 🤯" at face value.

Portable [Agent Skills](https://agentskills.io) — plain markdown + self-contained Python. They work in Claude Code, Codex, OpenCode, and any harness that supports the skills format and has web search.

Built in the open with [Claude Code](https://claude.com/claude-code) — an AI helped build the tool that fact-checks AI hype, and the [example report](./examples/report-14-ways-to-make-money-with-ai.md) is it auditing its own kind.

Follow [@SerhiiFounder](https://x.com/SerhiiFounder) for new skills and fact-check experiments, or [join the newsletter](https://korniienko.dev/newsletter) to get them in your inbox.

## Quickstart

1. Install [uv](https://docs.astral.sh/uv/) if you don't have it (the fetch script uses it to self-resolve its dependencies).

2. Run the skills.sh installer and pick the skills and agents you want:

```bash npx skills@latest add SerhiiKorniienko/bullshit-detector ```

3. Ask your agent: *"is this bullshit? \<url\>"*, *"fact-check this video"*, *"summarize \<url\>"*, *"explain the part at 12:30"*.

## Install as a Claude Code plugin

Prefer a managed bundle that updates when a new version ships, instead of copied files you maintain yourself? Inside Claude Code:

``` /plugin marketplace add SerhiiKorniienko/bullshit-detector /plugin install bullshit-detector@serhii-korniienko ```

Two ways to install, two philosophies:

- **[skills.sh](https://skills.sh/SerhiiKorniienko/bullshit-detector)** copies the skills into your setup so you can hack on them and make them your own. Works with any agent (Claude Code, Codex, OpenCode, …). - **The plugin** keep
