- Analyze URLs, YouTube videos, tweets, or text for quality, bias, and reliability using the Vajra API (vajra.to).

Also use when asked to "vajra" something or run content through a signal filter.

Vajra - Signal Filter for the Internet
Vajra is a content-analysis API by Humanity Labs. It scores content for epistemic quality (1-10), detects bias, extracts key takeaways, flags questionable claims, and produces structured verdicts.
Privacy and Data Handling
Important: This skill sends content to the Vajra API at https://www.vajra.to. Before using it:
- Content you submit (URLs, text) is transmitted to Vajra's servers for analysis.
- Analyzed content is cached server-side. If another user submits the same URL, they receive the cached result (0 credits). The original text you submit is not stored -- only the analysis output.
- Every analysis generates a public permalink (e.g.
vajra.to/a/ID). These are shareable and publicly accessible. - Do not submit private, proprietary, or personally identifiable content unless you understand and accept this behavior.
- Vajra's privacy policy and terms are available at vajra.to.
Setup
An API key is required. Get one free at vajra.to/dashboard (Connections tab).
The key must be stored as the environment variable VAJRA_API_KEY. The agent will be prompted to set this during installation.
