Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00115 | $0.02312 |
| Opus 5 | $0.00057 | $0.01156 |
| Sonnet 5 | $0.00023 | $0.00462 |
| Haiku 4.5 | $0.00012 | $0.00231 |
Grade A, and why
pci-dss-script-audit scanned grade A with 1 finding 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.

PCI-DSS Script Audit
Overview
This skill drives a deterministic audit workflow for PCI-DSS v4.0 Requirement 6.4.3 (script management on payment pages) and Requirement 11.6.1 (change and tamper detection). The agent must treat the skill steps as mandatory sequence—not suggestions—and produce verifiable artifacts (DOM snapshots, script inventory, SHA-256 hashes, header baselines, and diff reports).
Payment-page script attacks (Magecart, formjacking, skimming) bypass traditional WAF controls because malicious code executes in the browser DOM. This skill closes that gap by combining headless browser extraction via the official Playwright MCP server with cryptographic integrity verification and continuous baseline comparison.
When to Use
Use this skill when:
- Auditing a checkout, cart, or payment page for PCI-DSS v4.0 compliance
- Building or refreshing a script inventory with authorization status and business justification
- Verifying SHA-256 integrity hashes of inline and external JavaScript against an authorized baseline
- Running Requirement 11.6.1 monitoring (headers + DOM) on a schedule (at least every 7 days)
- Investigating alerts for unauthorized script additions, modifications, or deletions
- Reviewing Content-Security-Policy (CSP) and other security headers on payment pages
Do not use this skill when:
- The target is a non-payment page (blog, marketing landing page, internal admin console)
- The task is purely backend infrastructure (database encryption, OS hardening, vault key rotation)
- You lack authorization to scan the target URL or connect MCP tools to production systems
- You need HIPAA PHI redaction only (use a HIPAA-focused skill instead)
Core Process
Execute the following steps in order. Do not skip or reorder steps.
Phase A — Requirement 6.4.3: Script Authorization, Inventory, and Integrity
Step 1: Initialize audit context
- Record the audit metadata:
- Target payment page URL(s)
- Audit timestamp (UTC)
- Auditor identity / agent run ID
- PCI scope identifier (e.g., CDE checkout flow name)
- Confirm you have MCP access to the Playwright MCP server (official
@playwright/mcpor equivalent documented Playwright MCP implementation). - If Playwright MCP is unavailable, stop and report a blocking error—do not substitute manual curl or static HTML fetches for dynamic checkout pages.
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.

pci-dss-script-audit is a skill published in the GitHub repository vaquarkhan/compliance-agent-skills (2 stars, last pushed 17d ago), licensed MIT. It adds 115 tokens to every session and 2,312 once invoked, about $0.0006 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
