Flowsアプリのパフォーマンス問題を修正するために使用するスキルです。問題を報告するだけでなく、発見し修正します。
このスキルは、Flowsアプリケーションにおけるパフォーマンス問題を特定し、自動的に修正するために設計されています。主な対象問題は、不必要な再レンダリング、非効率なクエリ、ページネーションの欠如、無制限のデータ取得、バンドルサイズの肥大化、メモリリークなどです。このスキルは問題を報告するだけでなく、実際にコードを修正します。修正前後のパフォーマンス測定が常に要求され、効果を定量的に評価します。対象プラットフォームはFlowsアプリ（Reactなど）で、トリガーワードとして「performance」「slow」「laggy」「optimize」「re-render」「bundle size」「load time」「CDF query」「large list」「memory leak」「debounce」「virtualize」「lazy load」「code split」が使用されます。開発者がパフォーマンスチューニングを行う際の強力なアシスタントとして機能します。

This repo contains 20 individual skills — each has its own dedicated page.
MUST 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.
MUST 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.
MUST be used whenever creating an AtlasTool (client-side tool) for an Atlas agent. Do NOT manually write AtlasTool definitions or wire them into useAtlasChat — this skill handles the TypeBox schema, execute function, and hook wiring. Prerequisite: integrate-atlas-chat (vendored src/atlas-agent + TypeBox/AJV deps). This includes tools that fetch data, render UI, call APIs, show charts, query local state, or perform any browser-side action. Triggers: AtlasTool, client tool, add tool, create tool, new tool, tool definition, agent tool.
MUST 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 This skill finds AND fixes vulnerabilities, outdated packages, deprecated dependencies, and license issues — it does not just report them.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dependencies, packages, fix dependencies, update packages, fix vulnerabilities, npm audit fix, pnpm audit fix, CVE fix, outdated, deprecated, supply chain, license.
Simplified Aura guidance for selecting primitives, keeping token usage consistent, and applying reliable layout/copy/state patterns in Flows and Fusion apps.
Reference skill for CDF Data Modeling API best practices. Covers concurrency limits (avoiding 429s), pagination patterns for instances.list and instances.query, batching write operations, search vs filter guidance, and the QueuedTaskRunner (Semaphore) utility for controlling concurrent requests. Triggers: DMS limits, 429 error, rate limit, pagination, cursor, nextCursor, batching, semaphore, QueuedTaskRunner, cdfTaskRunner, instances.search, instances.list, instances.query, instances.upsert, concurrency, deadlock.
Run the technical (code) review step of Flows app certification. Produces three artifacts under reviews/code-review/feedback-round-<N>/: review-files.md (per-file inventory), review-packages.md (dependency audit), and code-review-report.md (scored report with Must Fix / Should Fix / Nice Fix items). Use when the user asks for a Flows code review, technical review, pre-submit review, app certification code review, or "run flows-code-review". Re-run until 0 open Must Fix items remain before moving on to flows-design-review.
Integrate 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.
MUST be used whenever building a chat UI with Atlas agents in a Flows app. Do NOT manually write useAtlasChat integration code — this skill handles installation, component structure, and hook wiring. Triggers: useAtlasChat, atlas chat, streaming chat, agent chat, chat interface, chat component, chat UI. For a full chat app, run skills in order: (1) integrate-atlas-chat, (2) create-client-tool (per tool), (3) setup-python-tools (if Python tools needed).
MUST 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.
Integrates a Flows/Dune app with the Fusion built-in PAIA agent panel using @cognite/app-sdk. Use this skill whenever a developer wants to: open the agent panel from their app, send the agent a contextual message, let the agent read app state (resources), or let the agent call actions in the app. Triggers: "fusion agent", "PAIA", "agent panel", "sendAgentMessage", "sendAgentLayoutMode", "agent server", "registerAgentServer", "connectToHostApp", "agent integration", "agent sidebar", "app-sdk agent". Always use this skill instead of manually writing agent integration code — it sets up the correct lifecycle, graceful fallback, and recommended file structure.
MUST be used whenever adding a task/todo list feature to a Flows app with Atlas chat. Do NOT manually create todo state management or tool definitions — this skill handles the full module (context, provider, tool, hooks, UI components) and all integration wiring. Prerequisite: integrate-atlas-chat must already be set up. Triggers: todo list, task list, task tracking, TodoWrite, todo panel, task panel, progress tracking, add todos, add tasks.
MUST 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.
Standard workflow for pulling updates from main or other branches on multi-contributor projects (including Flows apps) without silently discarding work. Guides fetching/merging, requires listing merge conflicts explicitly, analyzing ours vs theirs using conversation history and repo context, presenting prioritized recommendations, and obtaining user answers before editing conflict markers or completing the merge. Triggers: pull main, merge main, merge origin, rebase, merge conflict, unmerged paths, both modified, integrate branch, sync with main, git merge abort, resolve conflicts, UU status, theirs vs ours, feat branch update.
Integrates a local Cognite Reveal 3D CAD viewer bundle into Flows apps by copying app-local source code. Use when adding 3D viewer, 3D visualization, Reveal, CAD model, RevealProvider, RevealCanvas, Reveal3DResources, FDM 3D mapping, asset 3D model, model browser, or Cognite 3D content to a Flows application.
MUST 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.
MUST 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.
MUST be used when adding Pyodide or Python tool support to a Flows app. Do NOT manually configure usePyodideRuntime or wire pythonRuntime into useAtlasChat — this skill handles pyodide installation, hook setup, loading UI, and chat hook wiring. Prerequisite: integrate-atlas-chat (vendored src/atlas-agent + atlas chat wiring). Triggers: Pyodide, Python tools, pythonRuntime, usePyodideRuntime, runPythonCode, Python execution, client-side Python.
Create 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.
MUST 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.
