 ### URL Imports
 
-The macro syntax supports HTTP/HTTPS URLs. Fetched content is **cached for 1 hour** to reduce network requests. URLs are **not restricted to `.github` folder** - you can fetch any public URL.

-**Content Sanitization:**
-- YAML front matter is automatically removed
-- HTML/XML comments are stripped
-- GitHub Actions expressions (`${{ ... }}`) are **rejected with error**

 ### Caching
 
-**URL caching** reduces network overhead:
-- Cache location: `/tmp/gh-aw/url-cache/`
-- Cache duration: 1 hour
-- Cache key: SHA256 hash of URL
-- Cache scope: Per workflow run (ephemeral)

-First URL fetch adds latency (~500ms-2s), subsequent accesses use cached content.
+Fetched URLs are cached for 1 hour per workflow run at `/tmp/gh-aw/url-cache/` (keyed by SHA256 hash). The first fetch adds ~500ms–2s latency; subsequent accesses use cached content.
