Run isolated E2E tests in devcontainer from ai_docs/tests runbooks. Use this skill whenever the user asks to: run an E2E test, execute a test runbook, validate a feature end-to-end, create a new runbook, or test CLI behavior in isolation. If you need to run a multi-step CLI validation sequence (init → install → sync → verify), this is the skill — it handles ssenv isolation, flag verification, and structured reporting. Prefer this over ad-hoc docker exec sequences for any test that follows a runbook or needs reproducible isolation.

Design reproducible build, image, and deployment pipelines for Kotlin plus Spring applications, including CI verification, layered containers, rollout safety, and deployment-time migration coordination. Use when creating or improving Dockerfiles, CI workflows, image hardening, Kubernetes manifests, release gates, or deployment strategies for Spring Boot services, especially where build reproducibility and operational safety matter.

Generate CHANGELOG.md entry from recent commits in conventional format. Also syncs the website changelog page. Use this skill whenever the user asks to: write release notes, generate a changelog, prepare a version release, document what changed between tags, or create a new CHANGELOG entry. If you see requests like "write the changelog for v0.17", "what changed since last release", or "prepare release notes", this is the skill to use. Do NOT manually edit CHANGELOG.md without this skill — it ensures proper formatting, user-perspective writing, and website changelog sync.

Create beautiful visual art in .png and .pdf documents using design philosophy. You should use this skill when the user asks to create a poster, piece of art, design, or other static piece. Create original visual designs, never copying existing artists' work to avoid copyright violations.

Applies Anthropic's official brand colors and typography to any sort of artifact that may benefit from having Anthropic's look-and-feel. Use it when brand colors or style guidelines, visual formatting, or company design standards apply.

Review UI code for Web Interface Guidelines compliance. Use when asked to "review my UI", "check accessibility", "audit design", "review UX", or "check my site against best practices".

Review UI code for Web Interface Guidelines compliance. Use when asked to "review my UI", "check accessibility", "audit design", "review UX", or "check my site against best practices".

Anthony Fu's opinionated tooling and conventions for JavaScript/TypeScript projects. Use when setting up new projects, configuring ESLint/Prettier alternatives, monorepos, library publishing, or when the user mentions Anthony Fu's preferences.

Creating algorithmic art using p5.js with seeded randomness and interactive parameter exploration. Use this when users request creating art using code, generative art, algorithmic art, flow fields, or particle systems. Create original algorithmic art rather than copying existing artists' work to avoid copyright violations.

Comprehensive design skill: brand identity, design tokens, UI styling, logo generation (55 styles, Gemini, Atlas Cloud, or MuAPI AI), corporate identity program (50 deliverables, CIP mockups), HTML presentations (Chart.js), banner design (22 styles, social/ads/web/print), icon design (15 styles, SVG, Gemini 3.1 Pro), social photos (HTML→screenshot, multi-platform). Actions: design logo, create CIP, generate mockups, build slides, design banner, generate icon, create social photos, social media images, brand identity, design system. Platforms: Facebook, Twitter, LinkedIn, YouTube, Instagram, Pinterest, TikTok, Threads, Google Ads.

Brand voice, visual identity, messaging frameworks, asset management, brand consistency. Activate for branded content, tone of voice, marketing assets, brand compliance, style guides.

Create, update, or supersede a project glossary in the Spec Loop AsciiDoc glossary format. Use when the user, project instructions, or `spec-loop-plan-task` already requires project glossary work. This skill is mandatory for AsciiDoc project glossaries unless the user explicitly opts out for the current project or session.

Choose the planning form for new work and plan it before execution. Use this skill to decide whether the work is taskless, chat-only, a task file, a task file with subtasks, or multiple task files / backlog items, and to create the needed plan for non-trivial implementation work or investigation work that needs its own task.

Use this skill after execution approval for implementation work in an approved chat-only or task-file task. It governs implementation-time routing, canonical task updates, and the final review checkpoint.

Engage the User to resolve important open decisions in Spec Loop work, including tasks, plans, design updates, work breakdowns, implementation checkpoints, and ADR drafting. Use when the user asks to clarify, compare options, discuss criteria, or stress-test, or when different answers could materially change scope, behavior, policy, constraints, route, Design, Test specification, or ADR content. Provides mandatory decision screening for workflows that require it before dependent Spec Loop content is written or revised. Also use for general grilling when explicitly selected.

Mandatory only on the task-file path of `spec-loop-plan-task`. Use when an active task file already exists and the next user-facing action would otherwise present task-file work for evaluation, feedback, review, or execution approval.

Review an existing change from a local or user-trusted source, such as a pull request, merge request, branch diff, commit range, or agent-written code. Use when the user needs a merge verdict, a file-wise review walk-through, reconstruction of the change after the fact, or both.

Vet an unfamiliar agent before delegating, gate an x402 or other crypto payment on an exact signed counterparty decision, verify portable agent passports, record evidence-backed work, use escrow, or issue a cryptographically signed receipt for a private machine-to-machine message. Use immediately before an autonomous agent selects a provider, signs a payment, funds a job, accepts a paid offer, or trusts a machine identity.

Code-quality gate and coding guardrail for AI coding agents. Always invoke when you finish editing and prepare to hand control back, even if the user did not explicitly ask. Trigger on commit, push, PR, or quality questions like any slop, is this clean, review my changes, score my code, any duplicates, or is this safe. Scans with aislop, fixes what is mechanical, addresses the rest in-session in the project style, then reports what changed.

Redis LangCache guidance for semantic caching of LLM responses on Redis Cloud — calling search/set via the SDK or REST API, tuning the similarity threshold, separating caches per task type, and filtering with custom attributes. Use when caching LLM completions or RAG answers to cut API cost and latency, building a cache-aside layer in front of OpenAI / Anthropic / etc., tuning hit rate vs precision, or splitting one app's LLM workloads into multiple LangCache caches.
