secure-coding

secure-coding is a command for Claude Code, Cursor from MN-Lizard-Team/aiyu-multi-agent. It costs 0 tokens per session (511 once invoked), scanned A, original, Apache-2.0.

A secure-coding assistant for input validation, authentication, cryptography, and OWASP-oriented design. Cryptography protects information and communications through techniques such as encryption.

In plain words
What is it for?
Use it to identify trust boundaries, review security-sensitive code, and apply safer patterns for inputs, authentication, and data protection.
Why use it?
It helps address security risks while features are being designed and written, rather than only after deployment.

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

secure-coding 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 6d 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.

How it starts

The opening of the file, as written. The whole thing — 88 lines — stays where its author put it; the contents beside it link to each section on GitHub.

/secure-coding

Shift-left security coding — input validation, auth patterns, cryptography, and OWASP secure design principles. Used when writing new features or reviewing code for security anti-patterns.


⚠️ CURSOR OUTPUT CONTRACT

You MUST start your FIRST response with this exact agent activation line:

🤖 **Active Agent: `secure-coder`** | Skills: `clean-code, vulnerability-scanner, api-patterns, code-review-checklist`

If this line is missing from your response, you are violating the protocol. Add it before any other content.

Required Behavior

  1. Follow the task steps defined below
  2. Apply the Socratic Gate: ask clarifying questions if requirements are unclear
  3. Report completion status at the end

$ARGUMENTS


🤖 Agent Activation

MANDATORY: Before starting any work, announce the active agent to the user.

🤖 **Active Agent: `secure-coder`** | Skills: `clean-code, vulnerability-scanner, api-patterns, code-review-checklist`

Task

Apply security-first coding practices. Prevent vulnerabilities at design time, not after deployment.

Steps:

  1. Identify Trust Boundaries

    • Where does user input enter the system?
    • What data crosses network/API boundaries?
  2. Apply Input Validation

    • Type, length, range, format checks
    • Reject invalid input immediately
  3. Apply Output Encoding

    • HTML escape before rendering
    • SQL parameterize before querying
    • Shell-quote before system calls
  4. Authentication Review

    • Password hashing (Argon2id/bcrypt)
    • JWT expiry and rotation
    • RBAC on every route
  5. Cryptography Check

    • Secure random, not Math.random()
    • AES-256-GCM, RSA-4096
    • Secrets in env, never in repo

Usage Examples

/secure-coding review this API endpoint
/secure-coding add input validation to form
/secure-coding harden authentication flow
/secure-coding check for SQL injection risk
/secure-coding implement rate limiting

secure-coding is a command published in the GitHub repository MN-Lizard-Team/aiyu-multi-agent (7 stars, last pushed 3mo ago), licensed Apache-2.0. It costs nothing until one of its globs matches a file; then it loads 511 tokens. 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 2026-09-03.
