Conducts market, competitive, domain, and technical research using live web sources, producing a cited research-report.md to inform BMAD planning decisions. Use when the user says: - "research [topic/market/technology]" - "competitive analysis" or "who are the competitors" - "market size" or "market landscape" - "technical research" or "evaluate [technology/framework]" - "domain research" or "industry analysis" - "what does the market look like" - "find out about [technology/space]" - "I need research before we plan" - "gather information on [topic]" Supports three modes: Create (new research), Update (refresh existing report with new sources), Validate (cross-check claims in an existing report against live sources). Output lands in bmad-output/ as a cited research-report.md ready for downstream planning skills (business-analyst, product-manager, system-architect).
Build a distributable macOS DMG from an Xcode project via the bundled local helper — archive → export → package into one signed artifact. Resolves the project/workspace, scheme, team ID, and export options, regenerates the project first when `xcodegen` is detected, then runs `helpers/build-dmg.sh` from the project root instead of inlining xcodebuild. User-only workflow that touches code signing and provisioning: it never GUESSES the signing identity, never overwrites `ExportOptions.plist` without approval, and reports the built DMG path, version, and signing status. Use only when the user explicitly asks to build or package a DMG.
Use this skill when someone needs a Camunda 8 cluster to work against—run one locally to try a process, connect to SaaS or Self-Managed, switch profiles, or set local connector secrets—and before other skills run c8ctl. Installs and configures c8ctl, the Camunda 8 CLI. Not for databases or other local services
Use when maintaining legacy Canvas theme-global regions, region JSON, or a project-level Region-based layout. Also consult for existing region-based site chrome. Region APIs are deprecated; new integrations should use page variants and composed page trees instead.
Deep grill that interviews the user one question at a time AND verifies each answer against the codebase via background `answer-verifier-agent` calls. Catches factual conflicts, contradictions with prior decisions, and unfounded assumptions inline. Persists the session to `.chief/_grill/opened/NNNN-topic.md` so it survives context compaction. Use when the user wants a stress-tested grill — when stakes are high, when claims must be cross-checked against actual repo state, or when the topic spans many decisions. Heavier than `/grill-design`; prefer this when correctness matters more than speed.
Deep code simplification and refactoring preserving behavior across Python, Go, TypeScript, Rust. Targets complexity, anti-patterns, readability debt. Triggers on: "simplify this code", "refactor for clarity", "reduce complexity", "make this more readable", "tech debt cleanup", "too much nesting". NOT for deepening shallow modules or redesigning a module's interface or seam, use module-deepening.
Automated code review for Arduino/ESP32/RP2040 projects focusing on best practices, memory safety, and common pitfalls. Use when user wants code feedback, says "review my code", needs help improving code quality, or before finalizing a project. Generates actionable checklists and specific improvement suggestions.
Pixel-perfect Figma-to-React conversion using coderio. Generates production-ready code (TypeScript, Vite, TailwindCSS V4) with high visual fidelity. Features robust error handling, checkpoint recovery, and streamlined execution via a helper script.
Reverse-engineering a Sketch file (or Figma export with similar shape) into pixel-perfect React + CSS — the iteration mental model, tree reconstruction, layout inference algorithms, geometry math, visual-regression diffing, and the style/typography/path conversions that make "improvement without regression" enforceable. Trigger even if the user doesn't explicitly mention "algorithms" but is converting a design source into web code, building a design-to-code pipeline, or struggling to make incremental fidelity improvements without breaking previously-converted output.
Build high-performance APIs with Django-Bolt, including BoltAPI routes, typed request validation, msgspec serialization, auth guards, middleware, OpenAPI docs, pagination, streaming, SSE, WebSockets, and testing. Use when the user asks to create a new bolt endpoint, set up a Django-Bolt project, add JWT or API key auth, configure runbolt, wire guards or middleware, add pagination or streaming, generate OpenAPI docs, write TestClient tests, or migrate from FastAPI, Django REST Framework, or Django Ninja to django-bolt. Do NOT use for general Django views, Django admin customization, or standard Django REST Framework work.
Hardware-offloaded erasure coding with DOCA Erasure Coding (Reed-Solomon, doca_ec) on a BlueField DPU, ConnectX NIC, or host: generate parity for data blocks, rebuild lost blocks from survivors, and refresh parity after a change. Trigger on “one data block changed, how do I refresh parity without re-encoding,” “a disk failed and 2 parity blocks are gone, can I rebuild,” “RAID-6 resilience across 12 disks,” “my doca_ec_task_create returns NOT_PERMITTED,” or “is this N+K layout still recoverable,” even without naming DOCA Erasure Coding. Covers bringing up a doca_ec context; create / recover / update tasks; matrix type / N / K / block size; doca_ec_cap_* queries before sizing; doca_mmap src/dst permissions; and DOCA_ERROR_* from doca_ec_task_*. Refuse and route elsewhere for non-Reed-Solomon codes (fountain / LDPC / raptor), pure-replication designs, network FEC, or other DOCA accelerator libraries (SHA / Compress / AES-GCM / DMA)
Audits any developer documentation site across 33 checks in 7 categories and produces a scored report (out of 100) with Pass / Warn / Fail status per check. Use this skill whenever a user provides a docs URL and asks to audit it, review it, score it, check its quality, or evaluate it for AI discoverability, SEO, structure, content, or completeness. Also trigger when the user says "run a docs audit", "audit these docs", "check this documentation", "how good are the docs for X", or pastes a docs URL with any evaluative intent. Always use this skill — do not attempt a freeform docs review without following this structured workflow.
Look up CE.SDK React reference docs, guides, and configuration pages. Use when the user needs CE.SDK docs for React — configuration, UI customization, export options, feature guides, or getting-started instructions. Also triggered by “IMG.LY”, “CreativeEditor”, “CE.SDK”, or “cesdk” when the user needs an existing React doc page. Not for writing code (use build) or concept explanations (use explain). <example> Context: User asks about React configuration user: “How do I configure the editor in React?” assistant: “I'll use /imgly-sdk:docs-react to look up configuration options.” </example> <example> Context: User needs React component setup user: “How do I embed CE.SDK in a React component?” assistant: “Let me use /imgly-sdk:docs-react to find the relevant documentation.” </example>
Developer-experience friction auditing and fixing — slow onboarding, repeated manual setup steps, missing bootstrap/reset/seed scripts, undiscoverable conventions. Audits the repo, scores findings, scaffolds canonical fixes (bootstrap.sh, reset.sh, seed.sh, AGENTS.md, task-runner entries), then verifies the harness end-to-end in a scratch worktree against a 60-second time-to-first-commit target. Triggers on phrases like "audit dx", "fix dev friction", "time to first commit", "set up the harness", "I keep doing X manually", "every time I reset the db I have to...", and on new-repo bootstrapping. Even if the user doesn't say "DX" — if they describe a repeated manual chore in their dev loop, this skill applies.
Guide feature development for React applications with architecture focus. Covers Zustand/Redux patterns, IndexedDB usage, component systems, lazy loading strategies, and seamless integration. Use when adding new features, refactoring existing code, or planning major changes.
Create and manage GitLab projects, merge requests, pipelines, issues, branches, and more using the orbit CLI. Use this skill whenever the user asks about GitLab repositories, MRs (merge requests), CI/CD pipelines, branches, tags, commits, issues, groups, or project members. Trigger on phrases like 'list MRs', 'check the pipeline', 'create a branch', 'open a merge request', 'view the latest commits', 'list projects in group X', 'retry the CI', 'close the issue', 'who are the members', or any GitLab-related task — even casual references like 'what's running in CI', 'show me the MRs', 'tag a release', 'check if it merged', or 'list repos'. Also trigger when the user mentions PR/pull request in a GitLab context (GitLab calls them merge requests). The orbit CLI alias is `gl`.
Best practices for Flutter theming with Material 3, treating ThemeData as the single source of truth for colors, typography, component styles, and spacing. Use when creating, modifying, or reviewing ThemeData, ColorScheme, TextTheme, component themes, spacing systems, or light/dark mode support, and whenever widget code carries its own styling: a hardcoded Color, an inline TextStyle, raw padding or gap numbers, the same decoration repeated across widget instances, or a brightness/dark-mode conditional inside build, even when the request only says "review this widget", "cut the duplication", "stop repeating this", or "tidy this up".
Media player traps on Media3/ExoPlayer and desktop engines: crossfade, audio focus, fades, loudness, DSP, queues and shuffle, position restore, service lifecycle, group listening. Use when playback state, queue or audio levels go wrong.
Cross-platform real-time web research and search via an OpenAI-compatible Grok endpoint, returning JSON with content and sources. Use for version checks, API and docs verification, troubleshooting, and any time-sensitive facts on Windows, macOS, or Linux.
Codify reusable pygame patterns for entities, projectiles, movement, and sprite handling. Use when implementing pygame entities or systems that need frame-independent physics, collision detection, or sprite management. References verified patterns from project implementation.
Python backend implementation patterns for FastAPI applications with SQLAlchemy 2.0, Pydantic v2, and async patterns. Use during the implementation phase when creating or modifying FastAPI endpoints, Pydantic models, SQLAlchemy models, service layers, or repository classes. Covers async session management, dependency injection via Depends(), layered error handling, and Alembic migrations. Does NOT cover testing (use pytest-patterns), deployment (use deployment-pipeline), or FastAPI framework mechanics like middleware and WebSockets (use fastapi-patterns).
Expert React developer specializing in React 18+, Next.js ecosystem, and modern React patterns. This agent excels at building performant, scalable React applications using hooks, concurrent features, state management solutions like Zustand, and data fetching with TanStack Query
Design Rust library APIs that follow the Rust API Guidelines — naming (C-CASE, C-CONV, C-GETTER), interop traits (C-COMMON-TRAITS, C-CONVERT, C-ITER, C-SERDE), predictability (C-INTUITIVE, C-CONST), flexibility (C-GENERIC, C-NEWTYPE, C-EXT), type safety (C-BOOL, C-NONZERO, C-WRAPPER, C-STR), dependability (C-PANIC, C-UNWRAP), debuggability (C-DEBUG), and future-proofing (C-SEALED, C-STRUCT-FIELD, C-NON-EXHAUSTIVE). Use when users design a public crate API, choose between generics/concrete/newtype, decide trait bounds, hide implementation, avoid breakage, or ask "what is idiomatic Rust API design"; hand semver and publish workflow to rust-semver, lint config to rust-style-clippy, and in-crate layout to rust-module-layout.
Comprehensive Storyblok CMS development best practices for agency developers. Covers content modeling, SDK integration (React, Vue, Nuxt, Next.js), Visual Editor configuration, field plugins, API usage, internationalization, webhooks, and deployment patterns. Triggers on tasks involving Storyblok components, Visual Editor setup, content fetching, field plugin development, or headless CMS integration.
