CLI-Anything Bundle #11 — Time Recon Pack

Four NEW agent-native CLI harnesses that answer, in order, the time questions every AI agent runs into but usually improvises: what dates does this text actually contain, how long from A to B (with the time model stated, never assumed), what does this machine think time is, and what does this month actually look like. No timezone is ever invented silently.

The honesty law: a tool that silently assumes a timezone has already mis-scheduled something. Every conversion in this pack states its model, every assumption is stamped, every impossible input is a named refusal.

datepeek — what dates does this text contain

Read-only date-token recon over one file or stdin: counted classes (ISO date, ISO datetime with offset, RFC-2822, month-name, US slash marked ambiguous and never resolved), invalid-ISO accounting (2026-13-40 stays counted but is reported separately, never mixed into ranges), an aware-only ISO min/max range (naive wall times are never compared against timezone-bearing values), first-three samples per class, and opt-in 10-digit epoch-candidate scanning with explicit --epoch-decode.

durcalc — how long from A to B

Duration math between ISO-8601 timestamps: exact aware-aware arithmetic across differing offsets (13:30+05:30 minus 08:00+00:00 is honestly zero), naive-naive clearly labeled wall-clock, and a MIXED pair or list REFUSED with the reason (exit 2) instead of silently assuming a timezone. List mode sorts one-per-line timestamps (comments skipped) and reports span plus true min/median/max gaps — an even count averages the middle two and says so by returning a float.

tzpeek — what does this machine think time is

Local system timezone truth and explicit-offset conversion: what the host says right now (offset seconds + display, DST state, tz names, epoch) with the honesty stamp tz_database: not-read (stdlib time only); converts timestamps under two labeled models — aware inputs are exact, naive inputs are either stamped host-local ASSUMPTION (assumed_local: true) or given an explicit +HH:MM you name; --off on an aware input is refused (it would be a second opinion, not a source of truth); named offsets place naive timestamps (+03:00 12:00 > 09:00 UTC).

calpeek — what does this month look like

Calendar month recon and weekday scheduling math: real month length with honest leap rules (century rule applied — 1900/2100 are NOT leap years; 2000 is), first/last weekday names, weekday counts, ISO week numbers of the first and last day, the stdlib text table, and --nth/--last weekday lookups ("third Monday of the month") with honest misses — requesting the 9th Monday in a 4-Monday month is a named exit-1 finding, never clamped.

Install — one command

Copy any skill folder into your agent's skills directory (OpenClaw, Claude Code, Codex, or any Agent-Skills host), or run any harness as a plain CLI:

Verify before you trust

Every skill ships its own self-test battery that live-fires the real CLI on the running host (verified 2026-10-19: 10 + 16 + 14 + 14 = 54 checks, 0 failed):

Safety contract

Reads only the file or stdin you point at, computes with the stdlib, writes nothing, opens no sockets, sends no signals. Unreadable paths report honestly (exit 2); mixed time models and impossible months are named refusals, never stack traces.
