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 | $0.00114 | $0.01652 |
| Opus 5 | $0.00057 | $0.00826 |
| Sonnet 5 | $0.00023 | $0.00330 |
| Haiku 4.5 | $0.00011 | $0.00165 |
Grade A, and why
skill-security-auditor 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.

Security Auditor Guide
Overview
This guide covers security auditing workflows for source code, dependencies, and configurations. For detailed vulnerability patterns and detection rules, see references/vulnerability-patterns.md. For secrets detection patterns, see references/secrets-patterns.md.
Quick Start
Run the bundled scan script against a project directory:
python scripts/scan_project.py /path/to/project
This performs a lightweight scan for common issues: hardcoded secrets, dangerous function calls, and insecure patterns. For deeper analysis, follow the workflows below.
Testing the scripts
python scripts/scan_project.py /path/to/some/project --format text
python scripts/scan_secrets.py /path/to/some/project --format text
Audit Workflow
1. Reconnaissance
Before auditing, understand the project:
# Identify languages, frameworks, and entry points
find . -type f -name "*.py" -o -name "*.js" -o -name "*.ts" -o -name "*.go" -o -name "*.java" | head -20
cat package.json pyproject.toml requirements.txt go.mod pom.xml 2>/dev/null
Key questions:
- What frameworks are used? (Express, Django, Flask, Spring, etc.)
- Where are the entry points? (routes, controllers, API handlers)
- How is authentication handled?
- What external services are called?
- Is user input accepted? Where?
2. Secrets Detection
Scan for hardcoded credentials, API keys, and tokens. See references/secrets-patterns.md for the full pattern list.
python scripts/scan_secrets.py /path/to/project
Common patterns to check:
- API keys and tokens in source files
- Database connection strings with embedded passwords
- Private keys or certificates committed to the repo
.envfiles or config files with plaintext secrets- Secrets in CI/CD configuration files
3. Vulnerability Scanning
OWASP Top 10 Checklist
| # | Category | What to Look For |
|---|---|---|
| A01 | Broken Access Control | Missing auth checks, IDOR, privilege escalation |
| A02 | Cryptographic Failures | Weak algorithms, plaintext storage, missing TLS |
| A03 | Injection | SQL, NoSQL, OS command, LDAP, XSS |
| A04 | Insecure Design | Missing rate limits, business logic flaws |
| A05 | Security Misconfiguration | Debug mode, default credentials, verbose errors |
| A06 | Vulnerable Components | Outdated dependencies with known CVEs |
| A07 | Auth Failures | Weak passwords, missing MFA, session issues |
| A08 | Data Integrity Failures | Insecure deserialization, unsigned updates |
| A09 | Logging Failures | Missing audit logs, sensitive data in logs |
| A10 | SSRF | Unvalidated URLs in server-side requests |
What ships with it
5 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.
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.

skill-security-auditor is a skill published in the GitHub repository eigent-ai/eigent (15,170 stars, last pushed yesterday), licensed Apache-2.0. It adds 114 tokens to every session and 1,652 once invoked, about $0.0006 per session on Opus 5. A static security scan graded it A with 1 finding (runs shell commands). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
Other skills, from other repositories
commit
Atomic git commit with conventional message. Use when the user says "commit", "save my changes", "commit this", or wants to create a git commit. Stages specific files, writes a conventional commit message with body explaining non-obvious decisions. Never uses git add -A.
python-run
Run and debug Python scripts in the project. Use when the user says "run python", "execute this script", "debug this py file", or wants to run/modify a .py file. Handles dependency checks, linting, execution, and error analysis.
skill-packager
Authors Agent Skills v1.0 packages (SKILL.md plus references/scripts), runs packageskill to produce a standards-compliant zip, and uses installskill to add skills from HTTPS, registry, workspace, or an uploaded archive. Use when the user wants to turn documentation, workflows, or code into a portable skill, export a…
document-processor
Guidance for processing documents, extracting content, and transforming structured information. Use when the user asks to process, parse, extract, or transform document content such as PDFs, Word files, or spreadsheets.
workflow-helper
Guidance for creating, managing and executing workflow automations that chain multiple tools and agents together. Use when the user asks about building, listing, running or composing workflows and automated task pipelines.
attendance-signin-sheet
Generate printable attendance / 签到表 spreadsheets from name lists. Use when the user asks for 签到表, attendance sheet, meeting sign-in table, or similar printable roster tables (not full payroll attendance scoring unless asked).
