Use this skill when working with PostHog - product analytics, web analytics, feature flags, A/B testing, experiments, session replay, error tracking, surveys, LLM observability, or data warehouse. Triggers on any PostHog-related task including capturing events, identifying users, evaluating feature flags, creating experiments, setting up surveys, tracking errors, and querying analytics data via the PostHog API or SDKs (posthog-js, posthog-node, posthog-python).
Domain-Driven Design patterns. Bounded contexts, aggregates, entities, value objects, domain events, repositories, and application services. Strategic and tactical DDD for complex business domains. USE WHEN: user mentions "DDD", "Domain-Driven Design", "bounded context", "aggregate", "value object", "domain event", "ubiquitous language", "aggregate root", "domain service" DO NOT USE FOR: database schema design - use database skills; CQRS/Event Sourcing specifics - use `event-sourcing-cqrs`
Documentation reference for writing Python code using the browser-use open-source library. Use this skill whenever the user needs help with Agent, Browser, or Tools configuration, is writing code that imports from browser_use, asks about @sandbox deployment, supported LLM models, Actor API, custom tools, lifecycle hooks, MCP server setup, or monitoring/observability with Laminar or OpenLIT. Also trigger for questions about browser-use installation, prompting strategies, or sensitive data handling. Do NOT use this for Cloud API/SDK usage or pricing — use the cloud skill instead. Do NOT use this for directly automating a browser via CLI commands — use the browser-use skill instead.
When the user wants to implement, optimize, or use App Clips for app discovery and conversion. Use when the user mentions "App Clip", "app clip code", "mini app", "instant app", "App Clip card", "App Clip link", "no download required", "instant experience", or wants to understand how App Clips appear in App Store search. For general App Store discoverability, see aso-audit. For marketing campaigns, see ua-campaign.
State machine-based vector animation with runtime interactivity and web integration. Use this skill when creating interactive animations, state-driven UI, animated components with logic, or designer-created animations with runtime control. Triggers on tasks involving Rive, state machines, interactive vector animations, animation with input handling, ViewModel data binding, or React Rive integration. Alternative to Lottie for animations requiring state machines and two-way interactivity.
Perses plugin testing: CUE schema unit tests with percli plugin test-schemas, React component tests, integration testing with local Perses server, and Grafana migration compatibility testing. Use for "test perses plugin", "perses plugin test", "perses schema test". Do NOT use for dashboard validation (use perses-lint).
Validate content for joy-centered tonal framing. Evaluates paragraphs on a joy-grievance spectrum, flags defensive, accusatory, victimhood, or bitter framing, and suggests reframes. Use when user says "joy check", "check framing", "tone check", "negative framing", "is this too negative", or "reframe this positively". Use for any content where positive, curious, generous framing matters. Do NOT use for voice validation (use voice-validator), AI pattern detection (use anti-ai-editor), or grammar and style editing.
Salesforce Data Cloud Act phase. TRIGGER when: user manages activations, activation targets, data actions, or downstream delivery of Data Cloud audiences and data. DO NOT TRIGGER when: the task is segment creation (use sf-datacloud-segment), data retrieval/search work (use sf-datacloud-retrieve), or STDM/session tracing (use sf-ai-agentforce-observability).
Use for Cobo Agentic Wallet operations via the `caw` CLI: wallet onboarding, token transfers (USDC, USDT, ETH, SOL, etc.), smart contract calls, balance queries, and policy denial handling. Covers DeFi execution on EVM (Base, Ethereum, Arbitrum, Optimism, Polygon) and Solana: Uniswap V3 swaps, Aave V3 lending, Jupiter swaps, DCA, grid trading, Polymarket, and Drift perps. Use when: user mentions caw, cobo-agentic-wallet, MPC wallet, TSS node, Cobo Portal, agent wallet, or needs any crypto wallet operation — even without explicit "Cobo" mention. NOT for: fiat payments, bank transfers, or crypto-to-fiat off-ramp.
Produces rigorous, unambiguous mathematical specifications using sets, functions, relations, invariants, and explicit edge-case handling. Use when requirements are ambiguous, systems have interacting constraints, or behavior/contracts must be precise and falsifiable.
Human reviewer self-review for backend PRs — naming, complexity, DB schema, test design, type precision. Use when user says "review my PR", "check my PR", "human review", or wants design/readability feedback. Applies to any TypeScript backend; pair with pr-review-frontend for full-stack PRs.
A living swipe file of scroll-stopping hook templates collected from the wild — real sentence structures and native voice patterns that have proven they stop the scroll. Use this whenever writing hooks, opening lines, or scroll-stoppers, especially when combined with hook-writing and hook-tactics. Trigger any time the user wants hooks that feel native to the feed rather than constructed. These templates are the raw structural DNA of hooks that work — plug in the brand, persona, and pain to execute.
