Skill Content

## /yesterday Get the concrete date range for **yesterday** by running the bundled resolver: ```bash node "$AGENT_DIR/.claude/skills/temporal/when.mjs" yesterday ``` It prints a human-readable line plus a JSON record: - `start` / `end` — inclusive civil dates (`YYYY-MM-DD`) in your local timezone - `startUtc` / `endExclusiveUtc` — the same window as a half-open `[start, end)` range of exact UTC instants, for timestamp-based queries - `days`, `timezone`, `asOf` — the span, your timezone, and when this resolved Use the returned dates as the time bounds for the task at hand. **Do not derive dates by hand** — this resolver is the source of truth. For the full window list or an arbitrary range (e.g. `last45days`, `last6months`), see the `/temporal` skill.
