# gather.sh: one-shot dump of everything /daily Step 1 needs.
# Dumb on purpose: it prints, the agent judges. Every section skips cleanly
# when its tool or directory isn't there.
#
# Configure with env vars (or edit the defaults below):
#   DAILY_HOME           map.md + diary/ live here             (default ~/worklog)
#   DAILY_REPO           repo to scan for merges/pushes         (default: none)
#   DAILY_MAIN           mainline branch name                   (default main)
#   DAILY_TICKETS_CMD    prints tickets assigned to you         (default: none)
#   DAILY_MRS_CMD        prints your open PRs/MRs               (default: none)
#   DAILY_SESSION_DIARY  per-session Did/Next entries           (default ~/.claude/diary)
#   DAILY_EFFORTS        dir of <slug>/README.md effort homes   (default: none)
#   DAILY_BOT_AUTHOR     regex for agent commit authors         (default 'bot|agent|cursor')
#
# Examples:
#   DAILY_TICKETS_CMD='gh issue list --assignee @me'
#   DAILY_TICKETS_CMD='jira issue list -a"$(jira me)" -s"In Progress" --plain'
#   DAILY_MRS_CMD='gh pr list --author @me'
