Security
Secure environment variable management with Varlock. Use when handling secrets, API keys, credentials, or any sensitive configuration. Ensures secrets are never exposed in terminal, logs, or LLM context. Provides guidance around integrating varlock into a project, reading/editing .env.schema and other .env files, using the varlock CLI, adding plugins and framework integrations. Trigger phrases include "environment variable", "env var", "secrets", ".env", "API key", "credentials", "sensitive", "varlock"
Use this skill when creating, running, reattaching to, listing, stopping, or removing Docker Sandboxes (the standalone `sbx` CLI that runs AI coding agents in isolated microVMs), even if the user just says they want to "run claude in a sandbox", "isolate an agent from my repo", "give an agent its own git clone", or "clean up old sandboxes". Covers `sbx run`/`sbx create` (including the built-in agents claude, codex, cursor, devin, docker-agent, gemini, opencode, shell), workspace bind-mount vs `--clone` isolation, additional read-only workspaces, reattaching by `--name`, `sbx ls`/`stop`/`rm`/`prune`, `sbx exec`, `sbx cp`, and `sbx ports`.
Use this skill when configuring what a Docker Sandboxes (`sbx`) sandbox can reach on the network or which credentials it authenticates with, even if the user just says they want to "let the agent call an internal API", "block all network access", "give the agent a GitHub token", or "use a private registry image for a sandbox". Covers `sbx policy init/allow/deny/ls/inspect/log/check/rm network` (global and per-sandbox egress rules, deny-over-allow precedence) and `sbx secret set/set-custom/ls/rm/import` (service secrets, dynamic secrets via --ref/--command, and registry pull credentials with their host-pulls-only-by-default injection scope).
Parallel read-only multi-agent review of the current git diff or an explicit file scope, to find behavioral regressions, security or privacy risks, performance or reliability issues, and contract or test coverage gaps. Use when the user asks for a review swarm, parallel review, diff review, regression review, security review, or wants high-signal issues plus a prioritized fix path without editing files.
Use for authorized OSINT and cyber threat intelligence that enriches IOCs, campaigns, impersonation, scams, or threat actors from public sources. Includes bounded X/Twitter search through Xquik, source preservation, corroboration, and evidence handoff.
Compose IRQL (Incident Response Query Language) queries for Kusto cybersecurity investigations. Translates natural language hunting questions into composable IRQL pipelines using Get_*, Extract_*, and Enrich_* functions. WHEN: IRQL query, security hunt, threat hunting KQL, incident response query, compose hunting pipeline, failed logins, phishing investigation, lateral movement, process execution, file creation events.
Perform a focused security review of pending git changes to identify high-confidence security vulnerabilities with real exploitation potential. Use this skill when the user asks for a security review, security audit, vulnerability scan, or wants to check pending changes on a branch for security issues before merging. This is NOT a general code review
Apply IRQL graph functions to KQL or IRQL query results for visualization in Kusto Explorer. Generates Lift_To_Graph mappings and composes Graph_Render_View, Graph_Fold_By_Property, Extract_Node_*, Enrich_Node_*, and Enrich_Graph_* calls. Accepts a supplied query or limited basic natural-language source request; it is not a general natural-language-to-KQL/IRQL skill. WHEN: Lift_To_Graph, Graph_Render_View, Graph_Fold_By_Property, IRQL graph enrichment, graph mapping for existing query results, icon-decorated graph, fold graph nodes. Use azure-kusto-graph for native make-graph analysis, graph-match, shortest paths, components, or persistent graphs.
Use when Codex is already in the attack-path-analysis phase of a security scan or the user explicitly asks to trace a security finding from source to sink and calibrate severity. Do not use as the primary trigger for full PR, commit, branch, patch, or repository scans.
Guide for configuring Infisical Dynamic Secrets — on-demand, short-lived credentials for databases, cloud IAM, SSH, and Kubernetes. Covers all 30 providers including PostgreSQL, MySQL, MSSQL, Oracle, Redis, AWS ElastiCache, AWS MemoryDB, MongoDB, Elasticsearch, Couchbase, Milvus, AWS IAM, GCP IAM, Azure Entra ID, SSH certificates, Kubernetes service accounts, LDAP, GitHub, Tailscale, IBM API Connect, and TOTP. Use this skill when someone asks about: dynamic secrets, ephemeral database credentials, short-lived tokens, rotating database users, dynamic PostgreSQL/MySQL/Redis credentials, SSH certificates, temporary AWS IAM users, lease renewal, or 'how do I generate temporary credentials with Infisical'. For brand-new short-lived credentials created per request. Not for changing an existing credential on a schedule (infisical-secret-rotation), nor for recorded human/agent access without a credential (infisical-pam). Covers SSH certificates; TLS certificates are infisical-pki.
Apply when controlling access to VTEX IO app resources using role-based or resource-based policies. Covers policies.json for role-based access control, service.json policies for resource-based access, VRN syntax for principals, the difference between app-to-app and user/integration access, and GraphQL @auth directives. Use when deciding how to secure routes and restrict which apps, users, or integrations can access your endpoints.
Security patterns for authentication, defense-in-depth, input validation, OWASP Top 10, LLM safety, and PII masking. Use when implementing auth flows, security layers, input sanitization, vulnerability prevention, prompt injection defense, or data redaction.
Best practices for secure, gas-efficient Solidity smart contract development and Web3 frontend integration. Use when writing or reviewing Solidity contracts, hardening against reentrancy and access-control bugs, optimizing gas usage, setting up Hardhat/Foundry testing and static analysis, or wiring a React frontend to wallets, providers, and on-chain transactions.
Deploy and operate Infisical self-hosted instances with Docker, Docker Compose, and Kubernetes. Covers architecture, environment variables, ENCRYPTION_KEY management, PostgreSQL setup, Redis configuration (including the required noeviction policy), production hardening, FIPS 140-3 compliance, scaling, and high availability patterns. For deploying the Infisical platform itself. Not for the Kubernetes Operator, which is a separate Helm chart (infisical-kubernetes-operator), nor for using Infisical once running (infisical-setup).
Decode and inspect JSON Web Tokens (JWTs) without verification. Use when the user provides a JWT string and wants to see its header, payload, or claims — e.g. "decode this JWT", "what's in this token", "inspect this JWT", "show me the claims", "parse this token". Also triggers on raw JWT strings (three base64url segments separated by dots).
Use when writing Roblox game scripts that handle player actions, currencies, stats, damage, or any RemoteEvent/RemoteFunction communication. Use when reviewing code for exploitable patterns, implementing anti-cheat logic, validating client requests on the server, or setting up rate limiting.
