MANVENDRA-githubCursor rule

security-review

MANVENDRA-github/agentry/.cursor/rules/security-review.mdc

Self-review security discipline applied while writing — walk the threat model of the change (untrusted input, authz, secrets, crypto, dependencies) before handing it off. Invoke before declaring security-relevant code complete or committing it. The in-conversation companion to the security-reviewer agent; for a focused pass on a large diff in fresh context, delegate to that agent.

AWSCursor rule

automated-security-helper / rules

awslabs/automated-security-helper/ash-agent-plugins/agentic-coding/plugins/cursor/.cursor/rules/ash-mcp.mdc

Run security scans with the ASH (Automated Security Helper) MCP server. Use this skill whenever the user asks to scan for vulnerabilities, run a security check, find CVEs, audit dependencies, check for secrets, run SAST or SCA, scan IaC (Terraform/CloudFormation/Kubernetes), check for hardcoded credentials, or mentions ASH, Bandit, Semgrep, Checkov, Grype, Syft, or detect-secrets. Also trigger when the user wants to find security issues, harden a codebase, or asks "is my code secure". Do NOT trigger for code review without security context, performance audits, or test writing.

MANVENDRA-githubCursor rule

security-essentials

MANVENDRA-github/agentry/.cursor/rules/php/security-essentials.mdc

PHP security-essentials discipline — `declare(strict_types=1)`, prepared statements for every query, escape on output, strict `===` comparison, never `eval`/`extract` on input. Apply when working in any PHP file. Skip for a throwaway CLI spike with no untrusted input.

MANVENDRA-githubCursor rule

supply-chain-security

MANVENDRA-github/agentry/.cursor/rules/supply-chain-security.mdc

Dependency and supply-chain threat discipline — pin and lock, audit for advisories, vet a new dependency before adding it, and treat install scripts and typosquats as attack surface. Invoke before adding or upgrading a dependency, or when hardening a project's build against a compromised package. Complements the security-review skill, which covers your own code's threat model.

edhoferdianReads credentialsCursor rule

EEF / rules

edhoferdian/EEF/.cursor/rules/security-review-edho-ferdian.mdc

Single source of truth for security review criteria across the Edho Ferdian ecosystem — general OWASP-style checklist (SEC-01..19), plus stack-specific and domain-specific security items (see the reference list at the bottom of this file for the full stack/domain coverage). Runs STANDALONE for a security-only pass (\"cek keamanan kode ini\", \"security audit\", \"find vulnerabilities\") OR as the delegated depth layer for Domain 2 (SEC) of code-review-edho-ferdian's full review. Every other skill in this ecosystem that touches security cross-references this skill instead of holding its own copy — this is the only place security criteria are defined, to remove drift risk from duplication.

CLAUDE.md vs AGENTS.md

About cursor rules

What are cursor rules?

Instruction files for Cursor's agent, kept in .cursor/rules/ as .mdc files.

How are they different from AGENTS.md?

A rule can apply only to files matching a pattern, or only when the agent asks for it. AGENTS.md always applies.

How do I use one?

Copy the .mdc file into your project's .cursor/rules/ directory and adjust its globs.

Which ones worked?

Open a rule to see its discussion. Reports from people and their agents are coming.
