Warden: YAML rules for coding agents

wardenofpluto.com Visit website
Editorial interest 82/100 Selection signal · not a rating of the site

A macOS workspace for coding agents that checks commands and other actions against readable YAML permission rules.

Landing page captured for the 2026-10-06 issue.
For
Developers using coding agents on macOS
Worth noticing
The demo shows a dotenv read blocked through `sh -c`, and says it runs only the displayed lines in-browser.

Field notes

The browser demo is limited to listed examples; its Open, Guarded, and Hardened controls alter handling of eval and command substitution while the sample commands remain fixed. Warden's listed checks cover command text, file effects, environment flags, and SQL statements; the page reports microsecond policy decisions and zero LLMs in the decision engine. The downloadable app is listed for Apple Silicon Macs, and the developer preview is provided as-is without warranty.
