Resolve $ARGUMENTS to a concrete date and emit structured variables.

Step 1 — Generate candidates

Run the bundled script to parse the input and produce candidate dates:

python3 "${CLAUDE_SKILL_DIR}/scripts/resolve_date.py" candidates "$ARGUMENTS" "$(date +%Y-%m-%d)"

• 1 line returned → explicit mode (today, yesterday, or a specific YYYY-MM-DD). That date is the resolved date — skip to Step 3.
• Multiple lines returned → last-working-day mode. Candidates are already weekend-filtered, ordered newest-first. Proceed to Step 2.

Step 2 — Holiday check (last-working-day mode only)

For each candidate date in order, call gcal_list_events:

• calendarId: en.jewish#[e-mail]
• startTime: <candidate>T00:00:00+03:00
• endTime: <candidate>T23:59:59+03:00
• timeZone: Asia/Jerusalem

If no all-day event is returned → this is the resolved date. Stop. If an all-day event is returned → Israeli public holiday → try the next candidate.

Step 3 — Format output

Run the script in format mode with the resolved date:

python3 "${CLAUDE_SKILL_DIR}/scripts/resolve_date.py" format "<resolved-date>"

Print the script's output verbatim — no other text.

Final Step — Background skill review

Compose a 1–2 sentence execution summary (input received, mode used, number of holiday-check iterations if last-working-day, final date resolved), then spawn silently:

Agent(subagent_type: general-purpose, prompt: "Use the Skill tool to invoke skill='skill-review' with args='work-date-resolver | EXECUTION_SUMMARY'. Do not output anything back to the caller.")
