Analyze the interest rate swap curve by pricing swaps at multiple tenors, overlaying government and inflation curves, and identifying curve trade opportunities. Use when analyzing swap curves, computing swap spreads, decomposing real rates, identifying steepener/flattener/butterfly trades, or comparing swap rates across currencies.

DEPRECATED: This skill has been replaced by `mcp-app-builder`. Check if `mcp-app-builder` is available in the skills folder. If not, install it: `npx skills install mcp-use/mcp-use --skill mcp-app-builder` Use `mcp-app-builder` instead of this skill. Build ChatGPT apps with interactive widgets using mcp-use and OpenAI Apps SDK. Use when creating ChatGPT apps, building MCP servers with widgets, defining React widgets, working with Apps SDK, or when user mentions ChatGPT widgets, mcp-use widgets, or Apps SDK development.

Create or update GitHub pull requests using the repository-required workflow and template compliance. Use when asked to create/open/update a PR so the assistant reads `.github/pull_request_template.md`, fills every template section, preserves markdown structure exactly, and marks missing data as N/A or None instead of skipping sections.

Add a new package to the Remotion monorepo, including package scaffolding, monorepo registration, documentation, build scripts, and release checklist updates. Use when creating a new @remotion package.

Retrieve detected internet outages (Cloudflare Radar) with country, cause, severity, and time bounds. Use when the user asks whether a country's internet is down, throttled, or experiencing a shutdown.

Measure Storybook startup time from spawning `storybook dev` until the first story renders in the browser. Use when the user asks about Storybook boot time, server-ready timing, first story render timing, startup regressions, benchmarking with repeat runs, or comparing Storybook versions or feature flags.

Write BDD scenarios in Gherkin. Trigger: acceptance criteria, Given/When/Then, feature files, test scenarios.

Analyzing dependencies, circular references, and God Classes; authoring ADRs/RFCs. Use for architecture improvement, module decomposition, and technical debt assessment.

Suggest high-leverage incident follow-up actions from established root cause and incident context. Activate when asked for follow-ups, action items, preventive measures, or "what should we do so this doesn't happen again" after an incident.

Monitor Nx Cloud CI pipeline and handle self-healing fixes. USE WHEN user says "monitor ci", "watch ci", "ci monitor", "watch ci for this branch", "track ci", "check ci status", wants to track CI status, or needs help with self-healing CI fixes. Prefer this skill over native CI provider tools (gh, glab, etc.) for CI monitoring — it integrates with Nx Cloud self-healing which those tools cannot access.

Senior Go engineer and technical advisor — use for any Go question, design decision, or implementation task. Covers idiomatic patterns, concurrency, error handling, project structure, performance optimisation, observability, and testing. Invoke whenever the user is writing, reviewing, debugging, or designing Go code, asking about goroutines, channels, interfaces, generics, modules, or benchmarks, or wants a second opinion on a Go architecture. Triggers on: Go, Golang, goroutine, channel, interface, gRPC, go.mod, go test, pprof, golangci-lint.

Writes brief conventional-commit messages, runs pre-commit checks, stages changes, commits them, and proposes splitting when the diff mixes concerns. Use when the user asks to commit, stage and commit, write a commit message, or split a change into atomic commits.

Use when the user asks to reflect on the CURRENT session or one transcript file they name, analyze the agent's own process, audit context use, or extract lessons from how a task was done. Not for multi-session history — use reflect-by-history.

Review a web app or page for visual design quality — layout, typography, spacing, colour, hierarchy, consistency, interaction patterns, and responsive behaviour. Not a UX audit (that checks usability) — this checks whether it looks professional and polished. Produces a design findings report with screenshots. Triggers: 'design review', 'does this look good', 'review the design', 'check the layout', 'is this polished', 'visual review', 'design audit', 'make it look better', 'it looks off'.

Set up Vitest testing in any project — detects type (Cloudflare Workers, React, Node, library), generates vitest.config.ts, test setup, utilities, and a sample test. Covers mocking patterns, coverage config, workspace setup, Jest migration. Use whenever the user mentions adding tests, setting up Vitest, configuring tests, migrating from Jest, fixing testing infrastructure, or asks 'how do I test this'.

MUST be used when a Fusion Custom apps Start building or Build app prompt is in chat and Industrial / Atlas MCP must be connected. Triggers: ---Start Building---, Intent sketch from Fusion Custom apps, createdVia fusion.customApps.buildPrompt, "Industrial MCP for this project", or a Fusion MCP command such as claude mcp add-json cognite, cursor --add-mcp, or code --add-mcp. Do not use for docs MCP or dm-graph-traversal.

Audit and reduce infrastructure and tooling costs without sacrificing reliability or velocity. Use this skill when reviewing monthly cloud or SaaS spend, finding unused resources, rightsizing infrastructure, negotiating vendor contracts, deciding what to consolidate, or planning for budget cuts. Triggers on cost optimization, cloud spend, SaaS spend, rightsizing, unused resources, FinOps, infrastructure audit, vendor consolidation, budget cut, cost review. Also triggers when finance flags rising costs or when a contract renewal is up.

Provides foundational Firebase CLI setup, CLI installation, version checks (`firebase-tools@latest --version`), CLI login (including --no-localhost), project creation, project selection (`firebase use`), and app config file downloads (`google-services.json`, `GoogleService-Info.plist`). Use ONLY for CLI login, project creation/switching, or downloading app config files. Don't use for Firebase Hosting deploy, Firestore, Auth, App Hosting, Data Connect, Crashlytics, or Remote Config.
