What Verify Sources does

description: Verify all source URLs in TIPS.md are still reachable

/verify-sources — URL Health Check

Goes through all source URLs in TIPS.md and checks whether they are still reachable.

Local equivalent of the weekly-verify.md routine, but on-demand and interactive.

Workflow

Step 1 — Extract URLs

Read TIPS.md. Extract all source URLs using regex `\[.+?\]\((https?://[^)]+)\)`. Dedupe (one URL can cover multiple tips — threads).

Step 2 — Fetch in Parallel

Use web_fetch
