Apply when debugging. Trace each symptom to its root cause and fix it there; reproduce first, ask why until you reach it, resist nil-check guards that silence crashes.
Comprehensive DOCX import/export handling for Plate editor with tracked changes and comments. Use when implementing or debugging DOCX file operations, mammoth.js modifications, suggestion/comment import from Word, or export of Plate content to Word format. Triggers on requests involving DOCX import, export, tracked changes, Word comments, mammoth.js, or round-trip document fidelity. This skill ensures the agent understands the NON-NEGOTIABLE requirements for seamless Word ↔ Plate integration.
Use version control as a craft — atomic commits, buildable history, useful PRs, bisect-friendly main, recoverable mistakes. Use this skill whenever the task involves writing commits or PRs, choosing a branching model, deciding rebase vs. merge, recovering from a force-push or accidentally-committed secret, debugging a regression with `git bisect`, structuring a long change as a series of small reviewable steps, or judging whether a repo's history is readable. Use it especially when reviewing commit messages, PR descriptions, branching strategies, or merge policies. Built on Tim Pope and Chris Beams on commit messages, Paul Hammant on trunk-based development, Vincent Driessen on GitFlow (and his 2020 note retiring it for SaaS), Linus Torvalds on never rebasing public commits, and the Google Engineering Practices CL guide.
Integrates Material UI with Next.js App and Pages routers using @mui/material-nextjs, Emotion cache providers, next/font, CSS layers with Tailwind/CSS Modules, Link component prop patterns, CSS theme variables SSR notes, and App Router useSearchParams + Suspense. Use when setting up or debugging MUI in a Next.js app.
Guides development of Fastify Node.js backend servers and REST APIs using TypeScript or JavaScript. Use when building, configuring, or debugging a Fastify application — including defining routes, implementing plugins, setting up JSON Schema validation, handling errors, optimising performance, managing authentication, configuring CORS and security headers, integrating databases, working with WebSockets, and deploying to production. Covers the full Fastify request lifecycle (hooks, serialization, logging with Pino) and TypeScript integration via strip types. Trigger terms: Fastify, Node.js server, REST API, API routes, backend framework, fastify.config, server.ts, app.ts.
Package specification compliance for Elastic integration packages. Covers manifest structure (format_version, conditions, variables, routing rules), changelog schema and semantic version bumps, and alignment with the upstream elastic/package-spec. Use when building or reviewing manifest.yml, changelog.yml, or debugging elastic-package lint/check errors on package metadata.
Use when creating, running, or debugging elastic-package tests — pipeline fixture authoring and expected output, system tests with mock API wiring, and script tests for failure paths and upgrades. Load the reference file for the test type you are working on.
Use when debugging TypeScript/JavaScript bugs by tracing call chains, understanding unfamiliar codebases quickly, making architectural decisions, or reviewing code quality. Extract function signatures and JSDoc without full file reads, trace call hierarchies up/down, detect code smells, and follow data flow. Triggers on debugging, understanding codebase, architectural analysis, signature extraction, call tracing.
Use when building, auditing, styling, debugging, or optimizing Apache ECharts visualizations in vanilla JavaScript, React, or Vue applications — chart setup, lifecycle management, responsive resizing, theming, large datasets, streaming updates, server-side rendering (SVG in Node), and symptoms like a blank or empty chart, a chart that does not resize or update, stale series after switching chart types, or "component not exists" errors. Not for choosing chart types or visual design, and not for other charting libraries (D3, Chart.js, Highcharts).
Authoritative field/schema reference for 2130 STANDARD Salesforce objects — use to look up standard sObject and Tooling field API names, types, properties (filterable/sortable/groupable/updateable), and relationship names for Account, Contact, Opportunity, Lead, Case, ApexClass, ApexCodeCoverage, TraceFlag, and more. Load this alongside a SOQL/query/Apex skill when the field names, types, or Filter/Sort/Group capabilities are unverified — not when the fields are already known and only query syntax or optimization is needed. TRIGGER when verifying, validating, or debugging fields in a SOQL/SOSL query or DML against a standard object — capabilities, relationship/subquery paths, or what fields an object has — so the query runs instead of guessing. Custom __c objects and __c fields are NOT in these assets; describe the live org for those (sf sobject describe). DO NOT TRIGGER for authoring/deploying *-meta.xml or sfdx source (use the Metadata API skill).
Adds user authentication to web and mobile apps with Amazon Cognito (user pools and identity pools) and the AWS Amplify client auth libraries. Covers sign-up/sign-in flows and the login page (Cognito-hosted UI / managed login), MFA, password policies, OAuth 2.0 / OIDC flows (auth-code + PKCE, client credentials), social/SAML federation, tokens (ID/access/refresh, rotation, revocation, storage), Cognito Lambda triggers, identity pools (temp AWS creds), and gating API Gateway (or ALB) routes to signed-in users via Cognito/JWT authorizers. Applies when adding a login or sign-up page, configuring a user pool or app client, choosing user pool vs identity pool, wiring social/SAML, refreshing tokens, requiring sign-in on an API Gateway or ALB, or debugging redirect_uri/token/MFA/CORS/federation errors. Does NOT cover Amplify Gen2 backend definitions (defineAuth, npx ampx → aws-amplify), IAM/STS/Identity Center (→ aws-iam), or API Gateway/Lambda resource config beyond the authorizer (→ aws-serverless).
Datadog CLI for searching logs, querying metrics, tracing requests, and managing dashboards. Use this when debugging production issues or working with Datadog observability.
