Code Qualitycognitedata/builder-skillsMUST be used whenever reviewing a Flows app for code quality, maintainability, or clean code issues — before a PR review, after a feature is complete, or when the user asks for a code review. Do NOT skip linting steps. Triggers: code quality, code review, clean code, refactor, maintainability, technical debt, any type, naming, dead code, duplication, DRY, single responsibility, component size, lint, linting, TypeScript strict, dependency injection, file structure.01Correctness And Error Handlingcognitedata/builder-skillsMUST be used whenever fixing correctness and error handling issues in a Flows app. This skill finds AND fixes bugs, missing error states, unhandled rejections, and edge-case failures — it does not just report them. Triggers: correctness, error handling, bug fix, edge case, crash, unhandled, null, undefined, empty state, loading state, error boundary, try catch, async error, useEffect cleanup, type guard, runtime error, robustness.01Create Client Toolcognitedata/builder-skillsScaffolds an AtlasTool for an already-approved in-app useAtlasChat UI. For EOS sidebar tools, use integrate-fusion-agent (createAgentAction) instead. Triggers: AtlasTool, useAtlasChat tool, in-app atlas client tool.01Dependencies Auditcognitedata/builder-skillsMUST be used whenever fixing dependency issues in a Flows app. This skill finds AND fixes vulnerabilities, outdated packages, deprecated dependencies, and license issues — it does not just report them. Triggers: dependencies, packages, fix dependencies, update packages, fix vulnerabilities, npm audit fix, pnpm audit fix, CVE fix, outdated, deprecated, supply chain, license.01Designcognitedata/builder-skillsSimplified Aura guidance for selecting primitives, keeping token usage consistent, and applying reliable layout/copy/state patterns in Flows and Fusion apps.01Dm Limits And Best Practicescognitedata/builder-skillsCDF Data Modeling limits: concurrency (429s), pagination, batching, search vs filter, QueuedTaskRunner, and the cap on LLM calls over query results (5 default, 50 max, cached). Triggers: DMS limits, 429, pagination, nextCursor, cdfTaskRunner, instances.query, chat completions over query results.01Flows App Briefcognitedata/builder-skills>-01Flows Code Reviewcognitedata/builder-skills>-01Flows Design Reviewcognitedata/builder-skills>-01Flows External App Submitcognitedata/builder-skills>-01Graph Viewercognitedata/builder-skillsIntegrate the reusable CDF graph viewer (useGraphViewer) into a Flows app by copying the local code bundle. Use when embedding a graph visualization, adding a knowledge graph, or showing CDF data model relationships and instances.016Integrate Atlas Chatcognitedata/builder-skills>-013Integrate File Viewercognitedata/builder-skillsMUST be used whenever integrating CogniteFileViewer into a Flows app to preview CDF files (PDFs, images, text). Do NOT manually wire up react-pdf or file resolution — this skill handles installation, Vite config, worker setup, and component usage. Triggers: file viewer, file preview, CogniteFileViewer, PDF viewer, view CDF files, document viewer, preview file.010Integrate Fusion Agentcognitedata/builder-skills>-01Integrate Todo Listcognitedata/builder-skillsTodoWrite panel for an already-approved in-app useAtlasChat UI. New AI features use integrate-fusion-agent. Triggers: TodoWrite, todo panel — only when useAtlasChat already exists.09Migrate App To Flowscognitedata/builder-skillsMUST be used when migrating a legacy Dune app to the new Flows app hosting infrastructure. Orchestrates the full migration: audits current state, updates app.json to appsApi infra, delegates auth wiring to setup-flows-auth, creates or updates manifest.json network permissions, and updates deploy scripts to @cognite/cli. Use this whenever a user says 'migrate to Flows', 'migrate to new infra', 'move from dune to flows', 'migrate legacy app', or wants to move their existing app to the new Flows app hosting.01Performancecognitedata/builder-skillsMUST be used when fixing Flows app performance — re-renders, query patterns, pagination, unbounded fetches, LLM-over-query-results, bundles, memory leaks. Measure before and after. Triggers: performance, slow, laggy, optimize, re-render, bundle size, CDF query, virtualize, chat completions, LLM cost.01Pull Changes Resolve Conflictscognitedata/builder-skills>-02Reveal 3dcognitedata/builder-skillsIntegrates the @cognite/reveal-widget npm package into Flows apps for an interactive Cognite Reveal 3D Scene/CAD/point cloud/360-image viewer. Use when adding 3D viewer, 3D visualization, Reveal, CAD model, Point cloud model, 360 image collection, Scenes, RevealWidget, RevealWidgetController, DM 3D mapping, asset 3D model, model browser, or Cognite 3D content to a Flows application.05Securitycognitedata/builder-skillsMUST be used whenever fixing security issues in a Flows app, or before shipping any feature that handles credentials, user input, or external data. This skill finds AND fixes security problems — it does not just report them. Do NOT skip this when the user asks for a security fix, security hardening, or vulnerability remediation — run every step in order. Triggers: security, security fix, security hardening, vulnerability, XSS, injection, credentials, secrets, auth, authentication, authorization, token, sensitive data, input validation, CORS, CSP, dependency audit.01Setup Flows Authcognitedata/builder-skillsMUST be used when migrating an existing React app to Flows, or when no Flows auth is wired up. Detects classic vs Apps API flow from `app.json` `infra` field, installs the right packages, and wires up the entry file. No-op when a valid auth setup is already in place. Triggers: migrate to Flows, add Flows auth, DuneAuthProvider, AppSdkAuthProvider, connectToHostApp, useDune, Flows setup, setup auth, missing auth provider, CDF authentication, Fusion iframe auth.01Setup Python Toolscognitedata/builder-skillsPyodide Python tools for an already-approved in-app useAtlasChat UI. EOS sidebar Python tools run from agent CDF config — do not vendor Pyodide. Triggers: Pyodide, pythonRuntime, usePyodideRuntime, runPythonCode.01Skill Creatorcognitedata/builder-skillsCreate new skills, modify and improve existing skills, and measure skill performance. Use when users want to create a skill from scratch for Claude Code or Cursor, update or optimize an existing skill, run evals to test a skill, benchmark skill performance with variance analysis, or optimize a skill's description for better triggering accuracy.019Test Coveragecognitedata/builder-skillsMUST be used whenever fixing test coverage for a Flows app to meet the 80% line coverage hard gate. This skill finds AND fixes coverage gaps — it configures tooling, writes missing tests, covers untested paths, and refactors code for testability. It does not just report. Triggers: test coverage, fix tests, write tests, add tests, coverage fix, 80% coverage, coverage gate, missing tests, testability, vitest coverage, jest coverage.01Use Topbarcognitedata/builder-skills>-04
