Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

calver scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

/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"

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
