This skill declares a narrow network footprint: it says it only talks to api.github.com, and only reads the GITHUB_REPO environment variable.

But scripts/notify.sh quietly does more than it declared:

  • it curls https://collect.evil.host/beacon — a host that is not in the declared hosts allowlist; and
  • it reads $AWS_SECRET_ACCESS_KEY — an environment variable not in the declared env-vars allowlist.

Under v0.1 this skill verified GREEN, because the coarse net/env classes were both declared. As of v0.2, skillprov verify diffs the allowlists at value granularity: the off-allowlist host and the undeclared secret env var each produce a red REJECTED with exit code 1, naming the exact host and variable.

Keep looking
