vahtian: Skill for Claude Code

.claude/skills/vahtian-publishing/SKILL.md

vahtian-publishing is a skill for Claude Code from heidihelena/vahtian. It costs 130 tokens per session (2,187 once invoked), scanned A, original, Apache-2.0.

A release setup for publishing the project's Python and R packages. The packages are stored together in a monorepo, which is one repository containing multiple projects; the Python package is published to PyPI, while the R package targets R-universe and CRAN.

In plain words
What is it for?
Use it to configure publishing workflows, prepare releases, reserve package names, and verify matching results across the Python and R packages.
Why use it?
It organizes package releases and checks that the Python and R versions remain consistent, while publishing the Python package without storing a long-lived API token.

This is heidihelena/vahtian's own configuration. It tells Claude Code how to work on vahtian itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything vahtian configures →

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

vahtian-publishing 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 12d 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.

How it starts

The opening of the file, as written. The whole thing — 120 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Vahtian — publishing Python (PyPI) + R (CRAN / R-universe) from the monorepo

Both packages live in subdirectories of heidihelena/vahtian (the static site is at the repo root): packages/vahtian-py/ and packages/vahtian-r/ (R package name TBD — vahtian for brand parity, or vahtianR per the epinet convention). Same flagship name, same freeze/verify/audit core, byte-identical content_hash — so the headline CI gate is a cross-language parity test, not just two independent test suites.

Tags below: [do] (adopt — high impact-to-effort for a solo maintainer) · [over] (real but disproportionate for a solo, no-team product — skip for now).

A. PyPI — Trusted Publishing (no stored tokens)

The whole point: no API tokens in the repo. GitHub Actions authenticates to PyPI via OIDC; PyPI mints a project-scoped token valid for only ~15 minutes, so nothing leakable persists.

One-time setup — the workflow already exists; verify the PyPI side matches it:

  1. On PyPI → your account → Publishing → Add a pending publisher (GitHub). A pending publisher lets you reserve a not-yet-existent project; it auto-converts to a normal trusted publisher on the first successful publish — no manual first upload needed. Fields (must match the committed workflow exactly — PyPI matches on the literal filename):
    • PyPI Project Name: vahtian
    • Owner: heidihelena
    • Repository name: vahtian (this monorepo)
    • Workflow name: publish.yml (filename only — the committed workflow at repo-root .github/workflows/publish.yml)
    • Environment name: leave blankpublish.yml currently sets no environment:. If you later add a protected GitHub Environment ([do], gates who/what can publish), add environment: pypi to the publish job and set the same name on the PyPI publisher — the two must agree or the publish is rejected.
  2. Repeat on test.pypi.org for dry-runs (separate pending publisher).

What this file has done since we first saw it

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.
