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.

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".

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.

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.

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.

Define concepts, interface concepts, enumerations, and constrained data types in an MPS language's `structure` aspect. Covers smart-reference detection, alias rules, cardinality, INamedConcept usage, bulk creation, and the full `mps_mcp_perform_structure_operation` reference. Use when authoring or modifying a language's structure model.

Use when creating or changing MPS editor definitions — the overall workflow from scaffolding a `ConceptEditorDeclaration` through componentizing reusable `EditorComponentDeclaration`s, refining cell models and cell layouts, applying style sheets and indent-layout style items, wiring smart references, leveraging inheritance via super-concepts and interfaces, inspecting (`print_node_json`, `show_node_representation`) and validating (`check_root_node_problems`). Covers `jetbrains.mps.lang.editor` cell models (`CellModel_RefNode`/`CellModel_RefNodeList`/`CellModel_RefCell`/`CellModel_Property`/`CellModel_Constant`), layout choices, and JSON blueprints for common editor shapes. For the non-layout side (action maps, keymaps, transformation/substitute menus) use `mps-aspect-editor-menus-and-keymaps`.

Author and edit MPS `jetbrains.mps.baseLanguage` (Java) nodes — choose between the Java parser and JSON AST blueprints, map Java syntax to baseLanguage concepts/roles, harvest persistent member references, and validate. Use when writing class/method bodies, fields, expressions, statements, or any Java/BaseLanguage code inside MPS models, especially when BaseLanguage extensions (smodel, closures, collections) are involved.

Add, update, or delete MPS nodes using JSON blueprints — covers the unified blueprint format, staged construction for large subtrees, validation, and reference repair. Use whenever creating, editing, or restructuring nodes in any MPS model (structure, editor, behavior, generator, application code, etc.).

Analyze an MPS language by name — discover concepts, properties, references, children, aspects (editor/constraints/behavior), and metadata. Use when investigating an unfamiliar language, exploring concept structure, or finding sample nodes to use as templates for JSON blueprints.

Use when defining or debugging MPS dataflow builders for a concept — control/data flow declarations that drive reachability analysis and variable-use checking. Covers DataFlowBuilderDeclaration, BuilderBlock, emit instructions (code for, jump, ifjump, label, read, write, ret, mayBeUnreachable), positions (AfterPosition, BeforePosition, LabelPosition), the jetbrains.mps.lang.dataFlow language, the NodeParameter implicit, BL+smodel usage inside builder bodies, and IBuilderMode for advanced analyses such as nullable/non-null tracking.

Use when defining or modifying MPS generators — author a generator module, add or edit root/reduction/weaving/pattern mapping rules, attach template macros ($COPY_SRC, $LOOP, $IF, $PROPERTY, $REF, $SWITCH, $MAP_SRC, $WEAVE, $INSERT, $LABEL, $TRACE, $VAR), wire mapping labels, build template switches, write pre/post mapping scripts, navigate `genContext`, or debug "rule didn't fire", missing references, empty output, infinite reduction loops, and generated-Java compile failures.

Use when defining or editing MPS intentions (the Alt+Enter context-action aspect) — adding `IntentionDeclaration` roots, parameterized or surround-with variants, description/isApplicable/execute blocks, child-filter functions, factory-initialized AST splicing, or debugging why an intention is not offered. Lives in the language's `intentions` model and uses `jetbrains.mps.lang.intentions`.

Review a workflow-style PR's design, plan, and track files in research-mode Q&A; auto-records observations and submits a line-anchored review via gh api. TRIGGER when: user asks to review a workflow PR or run /review-workflow-pr. SKIP: non-workflow PRs without docs/adr/<dir>/_workflow/.

Migrate a branch's `docs/adr/<dir>/_workflow/**` artifacts to match workflow-format commits that landed on `develop` after the fork point. Replays each format-relevant commit's edits onto the branch's artifacts. Resumable across `/clear`. TRIGGER: branch has stale `_workflow/` after a workflow-format change on develop. SKIP: branches with no `_workflow/`.

Review code, test, and workflow-machinery changes across multiple dimensions using specialized agents with triage-based selection.

Research the codebase and create an implementation plan with architecture notes, design document, and track decomposition. Use when starting a new feature or large change.

Execute the implementation plan: autonomous plan review (Phase 2) on first invocation, then track-by-track execution (Phase A review + decomposition, Phase B implementation, Phase C code review). Use after /create-plan to implement the planned work.

Manually re-run the autonomous plan review (Phase 2 — consistency + structural). The same review runs automatically as the first phase of /execute-tracks; this command is for re-runs after inline replanning or whenever the plan needs explicit re-validation. TRIGGER when: user asks to re-validate the plan after inline replanning; user requests explicit plan review outside /execute-tracks. SKIP: /execute-tracks already running State 0 in this session (autonomous Phase 2 path will fire) — do not double-run.

Reviews any draft for AI writing tells and produces a clean rewrite. Catches vocabulary fingerprints (delve, tapestry, leverage, robust, multifaceted, navigate, foster), structural fingerprints (negative parallelism like "It's not X, it's Y", bullet-everything, Title Case headings, adjective triads), tone fingerprints ("Great question!", "I'd be happy to help", "In conclusion"), and punctuation fingerprints (em dash overuse, knowledge-cutoff disclaimers). Use this skill whenever the user asks to humanize, de-AI, edit, polish, or sanity-check writing, including phrases like "does this sound like ChatGPT", "make this less AI", "humanize this", "edit this draft", "remove the AI smell", "is this AI-y", or "clean this up". Also trigger when the user pastes a draft and asks for feedback on the writing without naming AI specifically.

Apply an edit to design.md or design-mechanics.md through the mutation discipline: apply → auto-review → iterate → present. Use this instead of directly Editing those files.

Run the full development pipeline autonomously without pausing between phases. Stops only on quality-gate failures.
