claude-code-config: Skill for Claude Code

Generate a standup report summarizing what was accomplished since $ARGUMENTS (default: smart lookback to previous workday noon ET — skips weekends and US federal holidays).

How to gather data

Step 1: Find repos and set time range

1. Find all repos the user works in. Check recent git activity across known repo paths. Start with the current working directory, then check other repos mentioned in conversation context or memory.

2. Determine the lookback cutoff. If the user provided an explicit $ARGUMENTS time reference, use it directly (skip to the ISO conversion below). If no argument was given, compute the smart default: find the most recent prior workday by walking backwards from yesterday, skipping weekends, US federal holidays, and the day after Thanksgiving (a de facto holiday for most organizations).

   Smart lookback algorithm (run only when $ARGUMENTS is empty):

   # Delegates to workday.sh, which implements the full weekend +
   # US-federal-holiday + day-after-Thanksgiving calculator with observed-date
   # rules (Sat → Fri, Sun → Mon) and cross-year lookbacks.
   #
   # Resolve the script path robustly: /standup runs from arbitrary repos,
   # so a bare `.claude/scripts/workday.sh` only works when CWD happens to be
   # this config repo. Check in this order: skills-worktree (canonical),
   # ~/.claude/scripts (global symlink fallback), git root of the current repo,
   # then CWD-relative.
   # Capture GIT_ROOT first and only include that candidate when non-empty —
   # otherwise `$(git rev-parse …)` expands to "" and the candidate becomes
   # `/.claude/scripts/workday.sh` (absolute-root path), which would
   # incorrectly match an unrelated root-level file if one existed.
   WORKDAY_SH=""
   GIT_ROOT=$(git rev-parse --show-toplevel 2>/dev/null || true)
   for candidate in \
     "$HOME/.claude/skills-worktree/.claude/scripts/workday.sh" \
     "$HOME/.claude/scripts/workday.sh" \
     "${GIT_ROOT:+$GIT_ROOT/.claude/scripts/workday.sh}" \
     ".claude/scripts/workday.sh"; do
     [ -n "$candidate" ] || continue
     if [ -x "$candidate" ]; then
       WORKDAY_SH="$candidate"
       break
     fi
   done
   if [ -z "$WORKDAY_SH" ]; then
     echo "Error: could not locate workday.sh" >&2
     exit 1
   fi
   # Preserve workday.sh's exit-code contract (exit 3 = runtime failure).
   # A plain `LOOKBACK_DATE=$(...)` would swallow non-zero exits and later
   # collapse them to a generic `exit 1`; `|| exit $?` keeps the original.
   LOOKBACK_DATE=$("$WORKDAY_SH" --last-workday) || exit $?
   # LOOKBACK_DATE is now the most recent prior workday (YYYY-MM-DD)
