Why use it?
It shows which scripts, styles, frames, forms, images, audio, or video use insecure connections and may be blocked or trigger browser security warnings.

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

mixed-content-audit 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.

The scan reads SKILL.md. This mod also ships 5 executable files (scripts/audit_resources.py, scripts/extract_resources.py, scripts/fetch_pages.py, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Mixed Content / HTTPS Audit

Audit an HTTPS site for insecure (http://) resources and produce an actionable report. Mixed content breaks pages and strips the padlock; this skill finds every instance and groups it by root cause.

When to use this skill

Use this skill when the user asks to:

  • Audit or fix mixed content / the browser "Not secure" warning
  • Find http:// scripts, styles, iframes, images, or media on https:// pages
  • Verify an HTTPS migration is complete
  • Find insecure form actions

Inputs to collect

  1. Site URL or URL list — a live https:// site root to crawl (auto-seeds from /sitemap.xml), or a text file with --url-list.
  2. Scope — pages to crawl (default 500, --max-pages).

Workflow

Step 1: Crawl and inventory subresources

Use scripts/extract_resources.py:

python3 scripts/extract_resources.py https://example.com --max-pages 500 --output resource_inventory.json
# already crawled once (e.g. in a full SEO audit)? skip the crawl and reuse the shared cache:
# python3 scripts/fetch_pages.py https://example.com --output page_cache.json
# python3 scripts/extract_resources.py --from-cache page_cache.json --output resource_inventory.json

For every page it records each subresource (scripts, stylesheets, images, iframes, media, embeds, form actions) with its tag, attribute, resolved URL, and scheme.

Step 2: Run the audit checks

python3 scripts/audit_resources.py resource_inventory.json --output audit_report.json

Step 3: Evaluate the audit checks

Evaluate each check in references/audit-checks.md. Core checks:

Check Severity
Active mixed content (script/style/iframe/object over http) High
Insecure form action (http) High
Passive mixed content (img/audio/video over http) Medium
Protocol-relative (//) resource Low
Page served over http Info

Step 4: Produce the report

Write a report following references/report-template.md: summary by severity, active mixed content and insecure forms first, then passive, grouped by the host serving the insecure resource, and a prioritized action list.

Changes

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.
