/calver

Compute / bump the CalVer version for arra-oracle-skills-cli.

⚠️ Pair with the right skill. This skill is --check (read-only) or --apply (writes package.json and stops). It does NOT commit, push, or PR — that's deliberate so a bump can never accidentally cut a release.

Want to…	Use
See the next target version	/calver (default = --check)
Just bump package.json and stop	/calver --apply
Cut a soak release (alpha pre-release)	/release-alpha
Cut a stable release on main	/release-stable
Land a code fix without releasing	regular branch + PR — keep package.json version untouched

Never combine a package.json bump with a code fix in the same commit on this repo — calver-release.yml auto-tags on push to main, so a fix-PR with a bump = automatic stable release.

CalVer scheme: v{yy}.{m}.{d}[-(alpha|beta).{HMM}] — HMM is the wall-clock as decimal H*100 + M with no leading zero (e.g. 09:37 → 937, 23:59 → 2359). Each minute is a unique slot — no merge-order collisions. Alpha and beta are independent channels (#754 / PR #783). Walks git tags AND package.json.version for source-of-truth (#784 / PR #786). TZ fixed to Asia/Bangkok. HMM replaced monotonic counter (#766/#775) in #923.

Day-of-month D may exceed 31 — used as a stable counter once natural date is exhausted (#930). E.g. v26.4.50 is the 50th stable cut in the period, not "April 50".

Step 0: Locate arra-oracle-skills-cli

Always resolve repo via ghq so the skill works from any cwd:

ARRA=$(ghq list -p --exact Soul-Brews-Studio/arra-oracle-skills-cli 2>/dev/null | head -1)
if [ -z "$ARRA" ]; then
  echo "❌ arra-oracle-skills-cli not found via ghq. Run: ghq get github.com/Soul-Brews-Studio/arra-oracle-skills-cli"
  exit 1
fi
echo "🕐 $(date '+%H:%M %Z (%A %d %B %Y)')"
echo "📁 $ARRA"

Modes

Default — dry-run check (show next target)

TZ=Asia/Bangkok bun "$ARRA/scripts/calver.ts" --check

Shows the next target version (max(tag-walk, package.json) + 1 for today's date+channel). No files modified.

--apply — bump package.json

TZ=Asia/Bangkok bun "$ARRA/scripts/calver.ts"

Writes the next version to package.json. Caller then:

git -C "$ARRA" add package.json && git -C "$ARRA" commit -m "bump: v<version>"

Do NOT auto-commit — hand off to user so they can bundle with other changes.

--stable — cut stable (no alpha/beta suffix)

TZ=Asia/Bangkok bun "$ARRA/scripts/calver.ts" --stable

--beta — cut beta (parallel channel, independent counter)

TZ=Asia/Bangkok bun "$ARRA/scripts/calver.ts" --beta

--stable and --beta are mutually exclusive (script exits 2).

--hour N — REMOVED

The --hour flag is deprecated as of #766 and will exit 2. CalVer now uses a monotonic counter walked from git tags + package.json — there is no hour-bucket to override.

--help — print calver.ts help

TZ=Asia/Bangkok bun "$ARRA/scripts/calver.ts" --help

After apply

Stop. Hand off to the user. Do NOT auto-commit, do NOT push, do NOT open a PR. The whole point of /calver being read-only-or-stop-after-write is so a bump can never accidentally turn into a release.

If the user wants to ship the bump, they invoke a release skill:

Next steps (user runs one of these — not /calver):
  /release-alpha    — soak channel, PR to alpha, calver-release.yml cuts pre-release on merge
  /release-stable   — stable channel (planned), PR to main, calver-release.yml cuts stable on merge

If the user is doing code-only work (no release), tell them to revert the package.json change before opening the PR. Bumping in a non-release branch is the exact failure mode /release-alpha was built to prevent.

Notes

• The calver.ts script is authoritative. Do NOT hand-compute versions.
• Release workflow: calver-release.yml tags on push to main when package.json version differs from latest tag. Post-#767, alphas merge to alpha branch (no tags created until stable cut to main); the script handles this by walking package.json (#784 / PR #786).

• Umbrella issue: #526 (maw-js — original); #284 (arra-oracle-skills-cli — this port).
• Related changes today (2026-04-28): #775 (monotonic counter), PR #783 (--beta channel for #754), PR #786 (package.json walk for #784).
