vahtian: Skill for Claude Code

.claude/skills/vahtian-brand-safety/SKILL.md

vahtian-brand-safety is a skill for Claude Code from heidihelena/vahtian. It costs 108 tokens per session (1,705 once invoked), scanned A, original, Apache-2.0.

A review guide for writing about Vahtian and its products. It keeps claims focused on whether a source supports a statement and whether the decision is recorded for later review.

In plain words
What is it for?
Use it to review or write Vahtian interface text, product descriptions, workflows, documentation, prompts, READMEs, social posts, advertisements, and landing pages.
Why use it?
It helps prevent exaggerated claims about truth, clinical validity, publication readiness, or what AI can decide. It keeps the human as the final decision-maker.

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-brand-safety 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.

Vahtian brand-safety reviewer

This skill keeps the site from drifting into AI hype. Vahtian is built by a clinician (MD, PhD); overclaiming is both a trust risk and a compliance risk.

This is the single canonical home of the invariant and copy rules. The other skills (vahtian-ux-auditor, vahtian-frontend-implementer, CLAUDE.md) defer here rather than restating them. In-repo source of truth for marketing claims: AD_CLAIMS.md — on any conflict between this skill and AD_CLAIMS.md, AD_CLAIMS.md wins; update this skill to match it, never the reverse.

The invariant (never let copy break this)

Vahtian assesses whether a cited source supports a specific claim, and records who decided what — with a human first, AI second, and an auditable trail. It does NOT certify scientific truth, clinical validity, manuscript quality, publication readiness, or the absence of citation problems.

Three rules that follow from it:

  1. The human decides. AI is a blinded second opinion the human can ignore, offered only after the human has rated. Copy must never make AI the judge.
  2. Support, not truth. Vahtian checks whether the cited source supports the sentence — not whether the sentence is true.
  3. No unbenchmarked accuracy claims. No percentages, no "catches every…", no "reviewer-proof" — there is no published validation study.

Forbidden / risky phrasings — flag every one

❌ Don't say Why it's unsafe
"verifies truth", "fact-check your paper", "make sure your claims are correct" Checks support, not truth
"guarantees", "proves", "100% safe", "never miss a bad citation" Guarantee with no benchmark
"fully automated review", "AI decides", "AI checks your citations" Makes AI the judge — breaks human-first
"AI-drafted/AI-generated peer review", "let AI review the manuscript", "outsource the review to AI" A peer reviewer accepts confidentiality, accountability, and IP-protection duties; drafting a review with a third-party AI breaks all three at once (Brem, Chiligireddy & Worthington, IEEE Eng. Manag. Rev. 2026, 10.1109/EMR.2026.3702480). Review-side tools assist a human on narrow, local, verifiable checks; they never draft, generate, or recommend the review, and nothing uploads
"publication-ready", "reviewer-proof" Certifies publication suitability
"eliminates bias" Overclaim; Vahtian records and preserves disagreement
"detects all citation errors", "99% accurate" Accuracy claim without published study
"certifies evidence", "verify your science", "clinical validity" Certification / truth framing
"anonymous" (for contributed data) Always "de-identified"; contribution is opt-in, default-off
"future-proof", "will open in any editor in twenty years", "works forever" Guarantee-shaped promise about longevity — say "most likely to still open", "opens in any editor today"
"studies show…", "most researchers find…" with no source Evidence claim without provenance — cite it or rewrite as reasoning from mechanism
"NVivo/MAXQDA cannot do X" (or any competitor claim) unchecked False competitor claims are the fastest trust kill with this audience — check the competitor's own docs; sell the differentiator that survives

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.
