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.
-
trustycap-technologies Skill Production Readiness AuditAudit an application for what it still needs before real customers use it: durable storage, data that survives a restart, work that happens later, incoming events that are not lost, mail that arrives, credentials that are not in the repository, and a way to know it is working. Produces a findings list ranked by what breaks first, and names which gaps the codebase already covers so nothing is recommended twice. Read-only: it installs nothing and changes nothing. Use when someone asks whether an app is production ready, what is missing before launch, or asks for a pre-launch or infrastructure review.
-
viachaslaustrelnikau Bundle Java TesterRisk-focused Java test design, implementation, review, and CI planning. Use when Codex needs to add, improve, review, debug, organize, or plan automated tests for Java applications, including unit tests, integration tests, Spring Boot tests, Spring Security authorization tests, REST/API tests, contract tests, Testcontainers-backed tests, database seeding and cleanup, Mockito-based collaborator tests, regression tests, flaky-test investigation, CI test strategy, or test-pyramid decisions.
-
viachaslaustrelnikau Bundle Add Production LoggingAudit, plan, add, improve, or review production logging and observability for a selected class, package, migrated operation, module, migration stage, or complete application. Use when Codex needs to preserve meaningful legacy logs, add diagnostic context to business operations and integrations, remove duplicate or unsafe logging, or perform a logging and observability audit without changing business behavior.
-
viachaslaustrelnikau Bundle Struts2 To Spring Migration Quality GateVerify that functionality migrated from Struts 2 to Spring works correctly in the running application from the API, client, and user perspective. Use after a migration step to gate a migrated action, route, workflow, form, grid, report, or state change through focused project-rule review, targeted build/tests, HTTP verification, browser E2E when UI integration matters, persistence checks for mutations, and optional old-versus-new comparison. Return PASS, FAIL, or INCOMPLETE. Do not use as a generic repository-wide Java, Spring, architecture, security, performance, or clean-code review.
-
vincenzoimp Bundle Adversarial ReviewUse when reviewing the survey, a contribution, or a paper draft as a severe but fair reviewer — claim audit, methodology critique, and venue-reviewer simulation before submission.

vetr0s Skill HowExplain how a subsystem works, at the level of an engineer being onboarded onto it. Use for "how does X work", "walk me through X", "explain this subsystem", a code walkthrough before changing something, and placement questions like "where should this live" or "which layer owns this". Can also critique the architecture on request. Use `audit` for whole-project health and `blast-radius` for what a change breaks.
