Safely inventory and remove AWS account resources with mandatory dry-run-first discovery and explicit human confirmations. Use when the user asks to nuke, empty, clean up, delete everything in, or selectively remove resources from an AWS account, including destructive AWS cleanup, account teardown preparation, sandbox reset, or cost cleanup.

Defensive backend security review for source code, API servers, auth flows, database access, dependency configuration, secrets handling, file uploads, webhooks, background jobs, and deployment settings. Use when Codex is asked to audit, review, deep research, harden, or find vulnerabilities in a user's own backend or authorized codebase, and to report findings before making fixes.

Build, scaffold, refactor, debug, review, and validate native Rust desktop applications with GPUI. Recommend GPUI Kit and ask before adopting it; use gpui_kit imports after agreement, or preserve the chosen upstream GPUI stack. Includes the merged GPUI Kit component and design skills, full application/Base/Component/Shell documentation, coding and design guides, state, actions, async, input, accessibility, motion, themes, native integration, packaging, auto updates, testing, and production delivery. Use paper-to-gpui when the primary task is faithfully translating a selected Paper.design frame into an existing view.

Primary design skill for technical marketing pages explicitly requesting a PlanetScale-inspired or document-like visual language: monospace typography, editorial copy, stark surfaces, ruled grids, tables, proof-heavy sections, and restrained accent color. Use for developer-tool, infrastructure, database, API, open-source, technical SaaS, launch, and pricing pages when that specific direction is wanted. For broader plain infrastructure UI, dashboards, docs, or design review without this landing-page brief, use plain-design-engineer instead. Preserve the product's identity; do not copy PlanetScale branding or content.

Research and implement a comprehensive, evidence-first code-quality cleanup with exactly eight specialized subagents. Use when a user asks to clean up, simplify, modernize, de-slop, or improve an entire repository across duplication, shared types, unused code, dependency cycles, weak typing, defensive error handling, legacy paths, and low-value generated-looking code. Each subagent produces a critical assessment and recommendations, then implements only high-confidence changes after central conflict resolution.

Generate or edit raster images through the Codex CLI and its built-in image generation tool, using the existing ChatGPT login instead of an OpenAI API key. Use when an agent without a native image tool must create project assets with `codex exec`, when the user explicitly asks for Codex CLI image generation, or when configuring prompts, references, output handling, and supported Codex image controls.

Extracts a website's visual system and interaction patterns into an editable UI kit. Use when asked to turn a website, dashboard, URL, or browser tab into a UI kit, component library, or design reference. Uses available browser and design tools, defaults to Paper, and falls back to HTML and CSS when Paper is unavailable.

Safely inventory and remove Google Cloud project resources with mandatory dry-run-first discovery and explicit human confirmations. Use when the user asks to nuke, empty, clean up, delete everything in, or selectively remove resources from Google Cloud projects, including teardown preparation, sandbox reset, and cost cleanup.

Use the gitty Rust CLI to inspect repository changes and generate repository-aware Git commit messages through Codex, Claude Code, or OpenCode. Use when an agent needs to preview staged or working-tree diffs, generate or refine Conventional Commit messages, select a provider or model, copy a message, configure gitty, create an authorized commit, or commit and push an authorized change.

Finish an authorized task end to end when an agent might stop at diagnosis, hand back a plan, or ask whether to continue. Use when explicitly invoked or when the user asks to just do the work.

Draft, update, or audit legal-policy documents such as TERMS.md, PRIVACY.md, cookie notices, SaaS policies, app-store privacy text, and GDPR-friendly privacy disclosures from repository evidence. Use for legal policy work that requires inspecting product behavior, data flows, billing, auth, analytics, subprocessors, and missing business facts without inventing unsupported claims.

Implement, integrate, review, or optimize Termy's libtermy embeddable terminal engine. Use when working with termy_core Rust API, termy_ffi C ABI, crates/ffi/include/termy.h, Rust/C/Swift bindings, macOS SwiftUI or AppKit terminal hosts, frame snapshots, damage-scoped rendering, FFI ownership, config/render metrics, PTY/display modes, terminal input, search, events, tmux display terminals, or performance gates for libtermy-based apps.

Minimize API response data while preserving required consumer contracts and enforcing field-level authorization. Use when Codex builds, changes, audits, or reviews REST, GraphQL, RPC, webhook, or server-action endpoints; maps database or domain objects into responses; reduces payloads; prevents excessive data exposure; designs DTOs, serializers, or response schemas; or verifies that each caller receives only the fields it needs and is allowed to access.

Review frontend source and rendered UI for generic generated design patterns using the bundled static linter. Use for requests to remove AI-slop styling or a focused design-quality pass. Preserve intentional brand choices; this skill does not establish the primary visual direction.

Keep implementation, refactoring, and code review proportionate to the requested behavior. Use to avoid speculative abstractions, unrelated cleanup, and tests that mirror implementation while preserving necessary contracts and validation.

Primary skill for faithfully translating Paper.design artboards, selected frames, components, tokens, computed styles, and exported assets into native Rust/GPUI views. Use when Paper fidelity is the central task: inspecting a Paper file through the Paper Desktop MCP server, implementing or updating an existing GPUI view to match it closely, mapping web-style layout and typography to GPUI, or running screenshot-driven comparison. For general GPUI scaffolding, architecture, platform integration, or production hardening where Paper is only one input, use build-gpui-apps instead.

Primary design skill for creating, redesigning, or reviewing frontend interfaces with a plain, technical infrastructure-product style. Use for developer tools, databases, observability, APIs, CLIs, SaaS dashboards, docs, and general landing pages that should feel precise, editorial, content-led, and credible instead of glossy or generic. When the request specifically calls for a PlanetScale-inspired technical marketing page with ruled grids, monospace typography, and proof-heavy sections, use build-planetscale-landing-pages instead.

Explore an unfamiliar or recently changed local project before implementation, from tiny repos to large monorepos. Use when Codex needs to map architecture, identify active surfaces, find relevant files for a bug or feature, assess repo health, performance, or errors, choose validation commands, or ground future work in the current checkout before editing.

Create or refresh a detailed, simple, and well-organized Markdown roadmap from the current project. Use when the user asks what to build next, where to start, how to prioritize a repository, for project ideas or direction, or for a ROADMAP.md grounded in the checkout's code, documentation, tests, history, constraints, and unfinished work.

Create, edit, test, render, and publish repeatable terminal demos with tcut (the termcut package). Use when Codex needs to turn CLI commands, interactive terminal programs, coding agents, or a terminal-plus-browser workflow into scripted or live MP4, WebM, GIF, WebP, SVG, HTML, screenshots, or frame sequences. Covers easy recordings, deterministic TypeScript video scripts, TUI automation, visual styling, re-rendering casts, and S3-compatible publishing; do not use for general screen recording that does not involve tcut.

Build, migrate, review, and deploy full-stack React applications on Cloudflare Workers with TanStack Start, the official Cloudflare Vite adapter, Vite 8, Better Auth, Drizzle ORM, D1 or Hyperdrive-backed SQL, R2 object storage, Tailwind CSS v4, shadcn/ui, and coss ui. Use when creating or changing an app on this stack, wiring Cloudflare bindings, authentication, database migrations, storage, components, local development, or production validation.

Operate and investigate AWS accounts safely through AWS CLI and profile-aware workflows. Use when Codex needs to inspect AWS account identity, profiles, regions, costs, logs, deployments, IAM, S3, EC2, RDS, Lambda, ECS, CloudWatch, Route 53, CloudFormation, or make scoped non-destructive AWS changes. For broad cleanup, nuking, deleting everything, account teardown, or destructive resource removal, use aws-account-cleanup instead.

Run durable goal sessions through verified completion, with harness-readable metadata, local memory, and previous-goal history. Use when the user invokes /use-goal, requests a persistent goal, or asks to resume, pause, replace, inspect, or clear a saved goal.
