# gitea skill — listar runs de Gitea Actions de un repo.
#
# Gitea 1.24 expone `/actions/tasks` (NO `/actions/runs`). El endpoint solo
# acepta `page` y `limit` — los demás filtros (workflow, branch, status,
# event, actor) se aplican client-side acá.
#
# Uso:
#   actions-list-runs.sh <owner>/<repo> [--workflow <filename>]
#                                       [--branch <ref>] [--status <s>]
#                                       [--event <e>] [--actor <user>]
#                                       [--limit N]

Uso: actions-list-runs.sh <owner>/<repo> [opciones]

Opciones (todas client-side, el server solo respeta page+limit):
  --workflow <filename>   ej. deploy-infra.yml (matchea workflow_id)
  --branch <ref>          ej. main (matchea head_branch)
  --status <s>            success | failure | running | waiting | cancelled
  --event <e>             push | pull_request | workflow_dispatch
  --limit N               cuántos traer del server (default 10)

NOTA: Gitea no devuelve el actor del run en /actions/tasks, así que no hay
filtro --actor. Si necesitás esa info, mirá el merge commit con git log.
