cuecards: Skill for Claude Code

.agents/skills/vc-security/SKILL.md

vc:security is a skill for Claude Code from opencue/cuecards. It costs 42 tokens per session (1,148 once invoked), scanned A, a copy of vc-security, MIT.

A security audit method based on STRIDE and OWASP, two established frameworks for finding risks in software and web applications.

In plain words
What is it for?
It is for auditing code for authentication, input-handling, data-protection, and other security problems, with an option to apply fixes.
Why use it?
It helps identify and rank security weaknesses before a release, deployment, or compliance review.

Skill for Claude Code

Written for Claude Code: argument-hint in frontmatter. Also seen: installed under .agents/ (shared by several agents).

This is opencue/cuecards's own configuration. It tells Claude Code how to work on cuecards 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 cuecards 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

vc:security 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 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.

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.

vc:security — Security Audit

Runs a structured STRIDE + OWASP security audit on a given scope. Produces a severity-ranked findings report. With --fix, applies fixes iteratively using the vc:autoresearch guard pattern.

When to Use

  • Before a release or major deployment
  • After adding auth, payment, or data-handling features
  • Periodic security review (monthly/quarterly)
  • Compliance check (SOC 2, GDPR, PCI-DSS prep)

When NOT to Use

  • Purely cosmetic changes (CSS, copy edits)
  • No user-facing code or data handling involved

Modes

Mode Invocation Behavior
Audit only /vc:security <scope> Scan → categorize → report
Audit + Fix /vc:security <scope> --fix Scan → categorize → fix iteratively
Bounded fix /vc:security <scope> --fix --iterations N Limit fix iterations to N

Audit Methodology

1. Scope Resolution

Expand the provided glob or full keyword into a file list. Read all in-scope files before analysis.

2. STRIDE Analysis

Evaluate each threat category systematically:

  • Spoofing — identity/authentication weaknesses
  • Tampering — input validation, integrity controls
  • Repudiation — audit logging gaps
  • Information Disclosure — data leakage, secret exposure
  • Denial of Service — rate limits, resource exhaustion
  • Elevation of Privilege — broken access control, RBAC gaps

3. OWASP Top 10 Check

Map findings to OWASP categories (A01–A10). See references/stride-owasp-checklist.md for per-category checks.

4. Dependency Audit

Run the appropriate package audit tool for the detected stack:

  • Node.js: pnpm audit
  • Python: pip-audit
  • Go: govulncheck
  • Ruby: bundle audit

5. Secret Detection

Scan for hardcoded API keys, passwords, tokens, and private keys using regex patterns. See references/stride-owasp-checklist.md → Secret Patterns.

6. Finding Categorization

Assign each finding a severity level (see Severity Definitions below).

What ships with it

3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.
