Security
Security agent skills give AI agents disciplined security workflows: code review for vulnerabilities, secret handling, dependency audits, and hardening checklists. Every skill on SkillMD also passes its own safety review before listing, with capability flags shown on each page.
-
hashgraph-online-awesome-codex-plugins Bundle SecurityRun authorized repository security scans for vulnerabilities, dependency risk, secrets, and binary policy. Triggers: "security", "run repository security scans for", "security skill".
-
hashgraph-online-awesome-codex-plugins Bundle Review CodeReview code changes for correctness defects, regressions, security risks, data-integrity problems, concurrency hazards, and missing meaningful tests. Use for pull requests, branches, commits, patches, or working-tree reviews; do not use for implementation unless the user separately requests fixes.
-

Triggers: "create a skill", "scaffold skill", "absorb external skill", "new skill", "heal skill", "repair skill hygiene", "audit skill structure", "check skill package".
-
hashgraph-online-awesome-codex-plugins Bundle Codebase ReconTrace a repo into cited flows. Not for a bounded question; that is research. Triggers: "codebase recon", "trace this codebase", "repository audit", "refresh the prior recon".
-
hashgraph-online-awesome-codex-plugins Bundle Review SecurityReview application and infrastructure changes for exploitable security risks by tracing assets, trust boundaries, attacker-controlled input, authorization, sensitive data, and dangerous sinks. Use for security reviews, threat-focused PR reviews, authentication or authorization changes, input handling, secrets, dependencies, and infrastructure permissions; do not use to exploit live systems or modify code unless separately requested.
-
alexzio00 Bundle Project CheckExisting project health scan — audits Infrastructure, Security, Quality, and Harness setup. Read-only. Use when: '/project-check', 'project health check', 'project audit', 'what's missing', 'analyze my project', 'check setup'. Ends with /project-init and /setup recommendations. NOT for new projects (use /project-init); project-check = shallow health scan.
-
nvidia-ai-iot Bundle Jetson Memory AuditMeasure Jetson DRAM/NvMap usage and verify before/after memory reclamation with live audit data.
-
nibzard Bundle Git XrayRun diagnostic git commands to assess a codebase's health before reading any code. Use this skill whenever the user asks you to understand a new codebase, audit a repo, assess technical debt, find risky code, check project health, figure out where to start reading, identify bus factor risks, or explore an unfamiliar repository. Also use it when the user asks 'what's going on in this repo', 'where are the problem areas', 'give me a health check', or 'what should I look at first'. If the user wants to understand a codebase at a strategic level before diving into code, this is the skill to use.
-
resciencelab Bundle Convex Performance AuditAudits and optimizes Convex application performance across hot-path reads, write contention, subscription cost, and function limits. Use this skill when a Convex feature is slow or expensive, npx convex insights shows high bytes or documents read, OCC conflict errors or mutation retries appear, subscriptions or UI updates are costly, functions hit execution or transaction limits, or the user mentions performance, latency, read amplification, or invalidation problems in a Convex app.

bex-co Bundle ValidationUse when Codex is already in the validation phase of a security scan or the user explicitly asks to determine whether one or more candidate security findings are valid. Do not use as the primary trigger for full PR, commit, branch, patch, or repository scans.
-
bex-co Bundle Fix FindingUse when the user explicitly asks to fix and verify a validated or plausible security finding. Do not use as the primary trigger for full PR, commit, branch, patch, or repository scans.
-
bex-co Bundle Security ScanUse for a standard, single-pass security audit of an entire repository or a scoped path, package, folder, or submodule with no diff to review. This is the default repository scan. Do not use for PR, commit, branch, or working-tree diffs, or for deep, multi-pass scans.
-
bex-co Bundle Track FindingsTrack validated Codex Security findings in Linear, Jira, GitHub issues, or draft GitHub security advisories. Use it for one finding or an explicitly selected batch of up to 25 findings tracked as Linear, Jira, or GitHub issues. Includes duplicate checks, exact previews, approval-gated writes, and readback. Do not use it for scans or fixes.
-
bex-co Bundle Assess Patch RiskAssess an immutable patch artifact's program impact, regression risk, and auto-merge eligibility. Use for generated patch files, provider pull-request diffs, or commit ranges when reviewers need evidence about affected runtime paths, contracts, tests, and recoverability. This skill is read-only and does not generate, edit, apply, push, or merge the patch.
-
bex-co Bundle Security Diff ScanReview a pull request, commit, branch diff, or working-tree patch for security vulnerabilities.
-
bex-co Bundle Attack Path AnalysisUse 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.
-
bex-co Bundle Propose Security HardeningDevelop evidence-backed structural and architectural security hardening proposals from vulnerability disclosures, supplied findings, incident or assessment documents, source code, or a completed Codex Security scan. Use when a user asks for systemic improvements, alternatives beyond per-finding patches, before-and-after security architecture views, engineering tradeoff analysis, or an implementation-ready plan for a selected hardening option. Also use automatically after a Codex Security scan with reportable findings when the top-level scan workflow requests final-report hardening guidance.
-
patrickserrano Bundle Xcode Disk CleanupAudit and safely clean Xcode-related developer storage on macOS. Use whenever a developer mentions low disk space, Xcode storage, DerivedData, simulator devices or runtimes, stale beta platforms in Xcode Settings, DeviceSupport, archives, dSYMs, CocoaPods caches, simulator dyld caches, project .build folders, downloaded Xcode DMGs/XIPs, duplicate Xcode installers, or old Xcode applications. Also use this skill proactively when you hit low storage during other work, such as a build, download, or install failing with an out-of-disk-space error. Always measure first, report recoverable GiB with evidence, and obtain explicit itemized approval before any mutation.
