Check stablecoins

This skill audits all stablecoin YAML files in eth_defi/data/stablecoins/ for liveness — checking whether their Twitter/X accounts are active and homepage domains are reachable. It adds a checks section to each file and attempts to fill in missing information. If wind-down news is found, it updates long_description.

Required inputs

None. The skill operates on the full set of stablecoin YAML files automatically. Optionally the user may specify:

1. Recheck mode - Whether to overwrite existing checks sections (default: skip files that already have checks)
2. Subset - A glob or list of specific YAML files to check (default: all *.yaml in the stablecoins directory)

Output format

Each YAML file receives a checks mapping with these keys:

checks:
  twitter_last_post_at: '2026-03-10'
  domain_up_at: '2026-03-17'
