repoforge: Skill for Claude Code

.claude/skills/main/test_security/SKILL.md

test-security-fixtures is a skill for Claude Code from JNZader/repoforge. It costs 28 tokens per session (385 once invoked), scanned A, original, MIT.

Testing guidance for security scenarios using prepared content and test users. It includes a scanner pattern for finding possible application vulnerabilities.

In plain words
What is it for?
Use it when retrieving test users, scanning an application for vulnerabilities, or running security tests with pytest.
Why use it?
It avoids unreliable or risky security tests based on hardcoded user data.

Skill for Claude Code

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

test-security-fixtures 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 1mo 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.

What it actually says

test-security-fixtures

This skill covers patterns for testing security using crafted content.

Trigger: Load this skill when working with test_security scenarios.

Quick Reference

Task Pattern
Get users for testing get_users()
Scan for vulnerabilities scanner()

Critical Patterns (Summary)

  • Get Users: Retrieve user data for security tests.
  • Vulnerability Scanner: Execute a scan to identify security issues.

Critical Patterns (Detailed)

Get Users for Testing

This pattern retrieves user data necessary for conducting security tests.

# Example of retrieving users
users = get_users()

Vulnerability Scanner

This pattern executes a scan to identify potential security vulnerabilities in the application.

# Example of running the scanner
results = scanner()

When to Use

  • When you need user data for security testing.
  • When scanning for vulnerabilities in your application.

Commands

pytest tests/test_security.py

Anti-Patterns

Don't: Hardcode User Data

Hardcoding user data can lead to security risks and unreliable tests.

# BAD
users = ["admin", "user1", "user2"]
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.

test-security-fixtures is a skill published in the GitHub repository JNZader/repoforge (5 stars, last pushed 24d ago), licensed MIT. It adds 28 tokens to every session and 385 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
