 ### Malware Blocking
 
-The Aikido Safe Chain works by running a lightweight proxy server that intercepts package downloads from the npm registry and PyPI. When you run npm, npx, yarn, pnpm, pnpx, rush, rushx, bun, bunx, pip, pip3, uv, uvx, poetry, pipx or pdm commands, all package downloads are routed through this local proxy, which verifies packages in real-time against **[Aikido Intel - Open Sources Threat Intelligence](https://intel.aikido.dev/?tab=malware)**. If malware is detected in any package (including deep dependencies), the proxy blocks the download before the malicious code reaches your machine.

-### Minimum package age
+### Minimum package age (npm only)
 
-Safe Chain applies minimum package age checks to supported ecosystems.
+For npm packages, Safe Chain temporarily suppresses packages published within the last 24 hours (by default) until they have been validated against malware. This provides an additional security layer during the critical period when newly published packages are most vulnerable to containing undetected threats. You can configure this threshold or bypass this protection entirely - see the [Minimum Package Age Configuration](#minimum-package-age) section below.

+⚠️ This feature **only applies to npm-based package managers** (npm, npx, yarn, pnpm, pnpx, bun, bunx) and does not apply to Python package managers (uv, pip, pip3, poetry, pipx).
-
-- npm-based package managers:
-  - during normal package resolution, Safe Chain suppresses versions that are newer than the configured minimum age from the package metadata returned by the registry
-  - for direct package download requests that bypass that metadata flow, Safe Chain can block the request itself using a cached list of newly released packages
-- Python package managers:
-  - during package resolution, Safe Chain suppresses too-young files and releases from PyPI metadata responses
-  - for direct package download requests that bypass that metadata flow, Safe Chain can block the request itself using a cached list of newly released packages
-
-By default, the minimum package age is 48 hours.

-git tag 1.0.0
-git push origin 1.0.0
-```
-
-This triggers the build pipeline, which compiles binaries for all platforms and creates a draft GitHub release.

-2. Open the draft release created for your tag
-3. Add release notes
-4. Click **Publish release**
-
-Publishing the release automatically triggers an npm publish. Pre-release versions (e.g. `1.0.0-beta`) are published to npm under a tag matching the pre-release identifier (e.g. `beta`). Stable versions are published to the `latest` tag.
