# Create a Gitea PAT with read access to the sibling API repos and store it as
# the SIBLING_REPOS_TOKEN action secret on leeworks-agents/api-company.
#
# Why this script exists:
#   - Gitea's build-docs workflow checks out sibling repos. The auto-injected
#     GITEA_TOKEN is scoped to THIS repo only and cannot read them, and
#     GITEA_TOKEN is a reserved secret name that cannot be overridden.
#   - `tea` cannot CREATE a PAT (no such command), and Gitea's token-creation
#     API requires BASIC AUTH (your password) — a token cannot mint a token.
#   - `tea` CAN set the action secret using its existing login.
#
# So: this prompts for your password ONCE, mints the PAT via the API, and pipes
# it straight into `tea` as the secret. The PAT value is never written to disk.
#
# Usage:  bash scripts/setup-sibling-repos-token.sh
