| description | Resolve "yesterday" to a concrete ISO date range relative to your run time —
yesterday. Returns inclusive civil dates plus exact UTC instants so you have
temporal context without computing dates by hand. Read-only: no writes, no
network. Use before a task scoped to yesterday (daily reports, "what changed yesterday").

/yesterday
Get the concrete date range for yesterday by running the bundled resolver:
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 timezonestartUtc / endExclusiveUtc — the same window as a half-open [start, end)
range of exact UTC instants, for timestamp-based queriesdays, 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.
