ruflo: Skill for Claude Code

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

security-audit is a skill for Claude Code, Codex from ruvnet/ruflo. It costs 81 tokens per session (751 once invoked), scanned A, original, MIT.

A code security scanner that checks for common vulnerabilities, including missing input checks, unsafe file paths, known CVEs, SQL injection, and insecure coding patterns.

In plain words
What is it for?
Use it to scan a codebase or focus on a particular directory and check, such as input validation, path traversal, or SQL injection.
Why use it?
It helps find security problems before they reach users, especially in code that handles accounts, payments, personal data, files, databases, or APIs.

Skill for Claude CodeCodex

Written for Claude Code: shipped in a Claude Code plugin. Also seen: installed under .agents/ (shared by several agents).

This is ruvnet/ruflo's own configuration. It tells Claude Code and Codex how to work on ruflo 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 ruflo configures →

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is npx @claude-flow/cli security scan --check input-validation --path ./src/api.

About the project

Ruflo is an execution and coordination layer for Claude Code and Codex that equips AI coding agents with tools, memory, control loops, sandboxes, and collaboration mechanisms. Developers use it to organize specialized agents into swarms, coordinate workflows, retain knowledge across sessions, and communicate across machines. The catalogue entries are Ruflo’s skills, commands, agents, hooks, and plugin components.

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

security-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 1mo ago.

The scan reads SKILL.md. This mod also ships 2 executable files (scripts/cve-remediate.sh, scripts/security-scan.sh), 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.

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.
