Run and generate NX targets, configure project.json, and visualize dependency graphs. Use when you say: 'run affected tests', 'nx generate a library', 'configure project.json', or 'show dependency graph'.

Convex reactive database patterns, schema design, real-time queries, mutations, actions, authentication, migrations, performance optimization, and component creation. Use when designing Convex schemas, writing queries/mutations, managing the Convex backend, setting up auth, migrating data, optimizing performance, or building Convex components.

Creates Contentful content types, queries entries via GraphQL/REST, runs CLI migrations, and manages assets and locales. Use when building or modifying Contentful content models, writing queries, or migrating content.

Creates pages/layouts, defines content collections, configures hydration directives, and wires integrations. Use when adding or modifying Astro pages, layouts, components, or content collections. Trigger terms: Astro, content collection, client:load, client:visible, astro:content

Creates Notion pages and databases, applies templates for research docs, ADRs, and specs, and manages team knowledge bases. Use when creating Notion pages, structuring databases, documenting decisions, or capturing research findings.

Drive real browsers via Chrome DevTools MCP: navigate pages, capture snapshots, run responsive checks, and collect console/perf traces. Use when the user mentions: 'validate UI change in Chrome', 'capture a screenshot', 'run responsive checks', or 'collect console logs'. Trigger terms: browser testing, DevTools, console logs, screenshot, responsive testing

Extract a DDD-style ubiquitous language glossary from the current conversation, flagging ambiguities and proposing canonical terms. Saves to UBIQUITOUS_LANGUAGE.md. Use when user wants to define domain terms, build a glossary, harden terminology, create a ubiquitous language, or mentions "domain model" or "DDD".

Create exercise directory structures with sections, problems, solutions, and explainers that pass linting. Use when user wants to scaffold exercises, create exercise stubs, or set up a new course section.

Import, host, qualify, and text-enable phone numbers for Sinch SMS using the Imported Numbers and Hosting Orders API. Use when importing non-Sinch numbers as DCA, creating hosting orders, qualifying numbers for text-enablement, managing LOA workflows, or checking hosting order status.

Search, rent, manage, and release phone numbers with the Sinch Numbers API. Use when listing active numbers, searching available numbers, renting or releasing numbers, updating number configuration (SMS/voice/callback), managing emergency addresses, or checking available regions.

Ultra-compressed communication mode. Cuts token usage ~75% by speaking like caveman while keeping full technical accuracy. Supports intensity levels: lite, full (default), ultra, wenyan-lite, wenyan-full, wenyan-ultra. Use when user says "caveman mode", "talk like caveman", "use caveman", "less tokens", "be brief", or invokes /caveman. Also auto-triggers when token efficiency is requested.

Adds dual EventCallback parameter aliases (bare and On-prefixed) to Blazor components for Web Forms migration compatibility. Guides creation of EventArgs classes, coalescing invocation patterns, and HasDelegate guard checks. Use when adding new event parameters to a BWFC component, implementing Web Forms event naming conventions, or migrating ASP.NET Web Forms event handlers to Blazor.

Browser automation with persistent page state. Use when users ask to navigate websites, fill forms, take screenshots, extract web data, test web apps, or automate browser workflows. Trigger phrases include "go to [url]", "click on", "fill out the form", "take a screenshot", "scrape", "automate", "test the website", "log into", or any browser interaction request.

Writes portable POSIX sh scripts with getoptions argument parsing, single-file builds, and production patterns (traps, temp files, logging, pipelines). Triggers: shell script, sh script, bash script, CLI tool, command-line tool, getoptions, argument parsing, Makefile recipe, cron job, init script, git hook, CI/CD shell step, deployment script, automation task. Do NOT activate for Python, Node.js, or other non-shell scripting tasks.

Uses a model checker's counterexample trace to localize the fault in the model, propose a fix, and propagate that fix back to the source code. Use when a model checker (TLC, NuSMV, Spin) finds a violation and you need to turn the trace into a code change, not just understand it.

Checks whether an implementation covers a set of requirements by tracing each requirement to code, tests, or both — and flagging gaps where a requirement has no evidence of implementation. Use when auditing for compliance, when answering "is this spec implemented", or before claiming a standard is supported.

Optimizes code for performance by identifying the actual bottleneck, choosing the right optimization lever, and measuring the result. Use when a specific operation is too slow, when a profiler has pointed at a hot path, or when the user asks to make something faster.

Translates pseudocode into idiomatic Java, inferring types, choosing collection classes, and handling exceptions per Java conventions. Use when implementing an algorithm from a paper or spec, when the user hands you pseudocode and wants Java, or when realizing a verified-pseudocode artifact.

Translates C++ functions into Dafny for formal verification, modeling pointers, fixed-width integers, and manual memory as Dafny heap objects and bitvectors. Use when verifying a C++ algorithm, when proving absence of overflow or out-of-bounds access, or when building a verified reference for safety-critical C++ code.
