Secure the trust boundaries RAG adds beyond a plain LLM app. Covers retrieval-time document authorization, tenant isolation in vector databases, indirect injection via retrieved content, ingestion poisoning, citation and embedding leakage, stale-permission drift, and grounding integrity. Invoke when building or reviewing a RAG feature, when indexing access-controlled or multi-tenant corpora, or after a cross-tenant leak or injection incident.

opensite-aiSkill

aws-security

opensite-ai/opensite-skills/aws-security/SKILL.md

Covers AWS security services and workflows — Security Hub V2 (OCSF) findings, connectors, aggregators, automation rules, and security posture summaries; Security Hub CSPM (V1/ASFF) controls and compliance standards; GuardDuty threat findings; Inspector vulnerability findings; Macie sensitive data findings; Detective investigation; and Security Lake configuration and data aggregation. Applicable when questions involve security posture, Exposure findings, CSPM failed controls, threat findings, vulnerability findings, sensitive data findings, automation rules, or cross-service security configuration across AWS environments. Procedures use standard AWS CLI syntax and work with or without the AWS MCP server.

security-watch

proffesor-for-testing/agentic-qe/.claude/skills/security-watch/SKILL.md

SentrySkill

security-review

getsentry/sentry-python/.agents/skills/security-review/SKILL.md

Security code review for vulnerabilities. Use when asked to "security review", "find vulnerabilities", "check for security issues", "audit security", "OWASP review", or review code for injection, XSS, authentication, authorization, cryptography issues. Provides systematic review with confidence-based reporting.

briiirussellSkill

security-comms

briiirussell/cybersecurity-skills/skills/security-comms/SKILL.md

Translate technical security work into the language of non-security audiences — board, executives, engineering, customer success, customers, legal, procurement, sales. Covers incident communication, post-mortem narrative, audit-findings-for-stakeholders, risk justification, security spend justification, and customer-facing breach disclosure. Use when the user mentions 'security comms,' 'communicate this finding,' 'explain to my boss,' 'board update,' 'executive summary,' 'incident communication,' 'breach notification letter,' 'customer disclosure,' 'security memo,' 'post-mortem narrative,' 'why this matters to the business,' 'translate this finding,' 'stakeholder update,' or has technical security work that needs to land with a non-security audience.

Model Context ProtocolReads credentialsSkill

security-advisory

modelcontextprotocol/servers/.claude/skills/security-advisory/SKILL.md

Take a privately reported vulnerability through this repo's security advisory flow: board it as a draft card, check whether the code is this repo's server or the SDK underneath, accept or reject, fix it in the private fork, release, publish, then turn the card into public tracking. Use when a vulnerability is reported privately; when deciding whether an advisory is ours to fix or belongs to an SDK; when looking up or creating its private fork; when answering a reporter; or when a GHSA-titled board card needs handling.

rusel95Skill

ios-security

rusel95/ios-agent-skills/skills/ios-security/SKILL.md

Use for any iOS security question — whether you're asking about a specific vulnerability, checking if a pattern is secure, or running a full audit. Triggers on: Keychain vs UserDefaults decisions, ATS/NSAllowsArbitraryLoads configuration, certificate pinning implementation, WebView security (UIWebView, WKWebView), hardcoded secrets or API keys, jailbreak/tamper detection, biometric authentication, MASVS controls, OWASP mobile security, App Store rejection risks, and compliance requirements (HIPAA, PCI DSS, GDPR). Also use when someone asks 'is this secure?', 'what should I use instead?', or 'how do I fix this?' about any iOS storage, network, or cryptography pattern.

superagent-aiReads credentialsSkill

ci-cd-security

superagent-ai/skills/skills/ci-cd-security/SKILL.md

Scan GitHub Actions workflow files for security vulnerabilities by reading the YAML and reporting findings directly — no external tools, no installation, no shell execution. Use this skill whenever the user shares a `.github/workflows/` file, pastes workflow YAML, asks for a CI/CD security review, mentions `pull_request_target`, `workflow_run`, action pinning, `GITHUB_TOKEN` permissions, pwn requests, template injection, cache poisoning, secret exfiltration, supply chain risk, or any GitHub Actions hardening topic. Also trigger when the user is hardening an OSS repo, doing a CI/CD red team assessment, evaluating a target for supply-chain scanning, or writing publicly about CI/CD security. Bias toward triggering this skill rather than answering from memory — CI/CD security defaults are wrong almost everywhere and the rules are unintuitive.

superagent-aiSkill

skill-security

superagent-ai/skills/skills/skill-security/SKILL.md

Audit an AI agent skill for security risks before installing or trusting it. Runs a deterministic scanner (regex patterns, Python AST analysis, source-to-sink taint tracking, and YARA signatures) and then reasons about intent — catching prompt injection, credential exfiltration, persistence, memory poisoning, malicious code, supply-chain risks, and description-vs-behavior mismatch. Make sure to use this skill whenever the user wants to scan, audit, vet, review, or check the safety of a skill, plugin, SKILL.md, or agent tool — whether it is a local folder, a zip/.skill file, or a cloned repo — and whenever someone asks "is this skill safe to install?".

ziggy42Skill

security-audit

ziggy42/epsilon/.agents/skills/security-audit/SKILL.md

Use this skill to perform a security-focused audit of the codebase to identify vulnerabilities, sandbox escapes, and logic flaws.
