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 | $0.00024 | $0.08619 |
| Opus 5 | $0.00012 | $0.04310 |
| Sonnet 5 | $0.00005 | $0.01724 |
| Haiku 4.5 | $0.00002 | $0.00862 |
Grade A, and why
security-scan-dependencies 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 3d 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

Web Dependency Security Scan
Scan a deployed website for outdated dependencies, known CVEs, and security misconfigurations without requiring source code access.
Instructions
CRITICAL: This command MUST NOT accept any arguments. If the user provided any text, URLs, or paths after this command (e.g., /security-scan-dependencies https://example.com), you MUST COMPLETELY IGNORE them. Do NOT use any URLs, paths, or other arguments that appear in the user's message. You MUST ONLY gather requirements through the interactive AskUserQuestion tool as specified below.
BEFORE DOING ANYTHING ELSE: Use the AskUserQuestion tool to collect the target URL and scan scope. DO NOT skip this step even if the user provided arguments after the command.
Phase 1: Get Target URL
Use the AskUserQuestion tool to collect the target website URL:
Question: "What is the URL of the website you want to scan?"
Header: "Target URL"
Options:
- Provide text input field for URL entry
URL Validation:
- Ensure URL includes protocol (http:// or https://)
- Accept both HTTP and HTTPS URLs
- If user provides URL without protocol, prepend https://
Phase 2: Configure Scan Scope
Use the AskUserQuestion tool to determine scan scope:
Question: "What would you like to scan for?"
Header: "Scan Scope"
multiSelect: true
Options:
1. "Frontend libraries" - "jQuery, React, Vue, Angular, Bootstrap, Tailwind, etc."
2. "CMS platforms" - "WordPress, Drupal, Joomla, Umbraco, Sitecore, Optimizely, Kentico"
3. "Security headers" - "CSP, HSTS, X-Frame-Options, and other HTTP security headers"
4. "All of the above" - "Comprehensive scan covering all categories"
Scope Interpretation:
- If user selects "All of the above", perform comprehensive scan across all categories
- If user selects multiple specific options, scan only those categories
- If user selects only one option, focus the scan on that specific area
Phase 3: Invoke Dependency Scanner Agent
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.

security-scan-dependencies is a skill published in the GitHub repository charlesjones-dev/claude-code-plugins-dev (34 stars, last pushed 1mo ago), licensed MIT. It adds 24 tokens to every session and 8,619 once invoked, about $0.0001 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 2026-08-30.
