Skill Claude CodeCodex

Captures, masks, compares, and updates screenshot baselines for web and mobile suites, with per-region thresholds and a reviewed-diff rule for every baseline change. Use when a screenshot assertion fails, a baseline needs updating, or visual checks are being added; not for deciding what to verify.

Skill Claude CodeCodex

Facilitate timed system-design interview practice across backend, mobile/client, SDK/library, and full-stack surfaces. Use risk-driven probes, an adverse timeline, mechanism revision, one changed constraint, and the existing six-criterion evidence-based debrief.

Skill Codex

Run a bounded cybersecurity exercise workflow with authorization, runtime, control, evidence, and independent adjudication gates; supports safe offline planning and optional isolated lab validation.

HoangNguyen0403/agent-skills-standard

Skill Codex

Controlled purple validation using paired action-observation evidence, explicit defensive outcomes, and optional isolated lab routing.

HoangNguyen0403/agent-skills-standard

Skill Codex

Evidence-led blue incident triage with authorization, runtime gates, and optional isolated lab retest handoff.

HoangNguyen0403/agent-skills-standard

Skill Claude CodeCodex

Define deterministic guardrails for agent tool calls — protected paths, test-file locks during bug fixes, post-edit formatters, production approval gates, secret deny rules. Use when writing or reviewing a hook policy, or moving an always-do-X rule out of prose into enforcement.

HoangNguyen0403/agent-skills-standard

Skill Claude CodeCodex

Define a repository review policy fixing what each review pass checks, how severities rank, which paths are skipped, the nit cap, and who approves. Use when review findings feel inconsistent or noisy, or when tuning an automated reviewer.

HoangNguyen0403/agent-skills-standard

Skill Claude CodeCodex

Define the delivery metrics contract for agent-assisted SDLC — DORA four plus per-stage indicators derived from artifact and git history, and the control bands that turn metric drift into a routed intake. Use when reporting cycle time, plan adherence, or defining response thresholds.

HoangNguyen0403/agent-skills-standard

Skill Codex

Turn a control-band breach or scheduled scan result into a tiered, evidence-backed response and a routed intake.

HoangNguyen0403/agent-skills-standard

Skill Claude CodeCodex

Right-size, ground, and gate SDLC decisions with SNC-sized depth, said-vs-assumed write-back, an evidence ledger, honest option cards, recorded approval, and self-review. Use when running brainstorm-feature, plan-feature, design-solution, or system-design-session.

HoangNguyen0403/agent-skills-standard

Skill Claude CodeCodex

Validates cyber exercise authorization, scope, exclusions, runtime controls, expiry, stop and restart gates. Use when planning or reviewing authorized security activity, scope drift, or unsupported execution environments.

HoangNguyen0403/agent-skills-standard

Skill Claude CodeCodex

Designs and reviews detections from telemetry prerequisites, correlation logic, Sigma metadata, severity, status, and benign cases. Use for detection rules, Sigma review, analytic coverage, or tuning; not generic logging advice or live deployment.

HoangNguyen0403/agent-skills-standard

Skill Claude CodeCodex

Validates defensive controls with paired authorized action and observation evidence, distinguishing blocked, prevented, detected, responded, and telemetry-gap outcomes. Use for purple-team validation design or offline fixture review; not unsanctioned testing or production efficacy claims.

HoangNguyen0403/agent-skills-standard

Skill Claude CodeCodex

Drafts bounded cybersecurity engagement plans with objectives, scope, exclusions, roles, authorization, runtime controls, evidence, stop criteria, and restart gates. Use when preparing an exercise or assessment plan before execution.

HoangNguyen0403/agent-skills-standard

Skill Claude CodeCodex

Captures redacted, provenance-aware cybersecurity observations with shared status fields, independent ground truth, and honest limitations. Use when recording exercise evidence, findings, validation results, or security-review handoffs.

HoangNguyen0403/agent-skills-standard

Skill Claude CodeCodex

Adjudicates authorized exercise outcomes against independently held ground truth, redacted evidence, and explicit status boundaries. Use when comparing observations, resolving discrepancies, or preparing evidence-led security-review handoffs.

HoangNguyen0403/agent-skills-standard

Skill Claude CodeCodex

Controls authorized cybersecurity exercises through inject scheduling, safety gates, stop and restart decisions, communications, and synthetic-data boundaries. Use when serving as exercise control or white-team coordinator, not as compliance assessor or whitehat operator.

HoangNguyen0403/agent-skills-standard

Skill Claude CodeCodex

Maintains sparse, reviewable cybersecurity framework edges with versioned IDs, relation, rationale, source, and review status. Use when mapping exercise observations or procedures to NIST, ATT&CK, or another named framework.

HoangNguyen0403/agent-skills-standard

Skill Claude CodeCodex

NIST SP 800-61r3-aligned incident triage that preserves evidence, separates analysis from authorization, and records status. Use for incident intake, severity assessment, containment readiness, or evidence preservation; not generic debugging or unscoped response.

HoangNguyen0403/agent-skills-standard

Skill Claude CodeCodex

Validates bounded cybersecurity exercise observations against approved scope, expected behavior, runtime controls, and redacted evidence. Use when performing safe offline validation or authorized runtime checks with explicit stop and status gates.

HoangNguyen0403/agent-skills-standard

Skill Claude CodeCodex

Conducts hypothesis-driven, evidence-preserving threat hunts with bounded negative conclusions and telemetry-gap handling. Use for hunt hypotheses, scoped offline analysis, or analytic follow-up; not unscoped scanning, malware execution, or generic intelligence summaries.

HoangNguyen0403/agent-skills-standard

Skill Claude CodeCodex

Judge and shape UI/UX for products used by parents and young children - audience fit, accessibility, safety and trust, comfort, consistency, and human feel. Use when reviewing or designing family, parenting, or kids app screens on phone or tablet.

HoangNguyen0403/agent-skills-standard

Skill Claude CodeCodex

Drive Google Stitch over MCP safely - read screens, write and lint DESIGN.md, create design systems, and fix designs through variants instead of overwriting. Use when reviewing, editing, or generating Stitch screens or DESIGN.md files.

HoangNguyen0403/agent-skills-standard

Skill Claude CodeCodex

Execute an approved implementation plan at the context boundary that preserves required independence and review. Use when implementing plans, executing multi-task PRs, choosing between main-loop and dispatched execution, or transitioning from planning to implementation.
