Skill v1.0.0

version: "1.0.0" name: thisMonth description: | Resolve "thisMonth" to a concrete ISO date range relative to your run time — this month so far (1st → today). 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 month-to-date task (MTD metrics, "so far this month"). allowed-tools:

• Bash

/thisMonth

Get the concrete date range for this month so far (1st → today) by running the bundled resolver:

node "$AGENT_DIR/.claude/skills/temporal/when.mjs" thisMonth

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.
