Implement backup strategies, disaster recovery plans, and data restoration procedures for protecting critical infrastructure and data.

Implement canary deployment strategies to gradually roll out new versions to subset of users with automatic rollback based on metrics.

Build high-performance gRPC services with Protocol Buffers, bidirectional streaming, and microservice communication. Use when building gRPC servers, defining service contracts, or implementing inter-service communication.

Identify and debug performance regressions from code changes. Use comparison and profiling to locate what degraded performance and restore baseline metrics.

Profile application performance, identify bottlenecks, and optimize hot paths using CPU profiling, flame graphs, and benchmarking. Use when investigating performance issues or optimizing critical code paths.

Facilitate effective retrospectives to capture lessons learned, celebrate successes, and identify actionable improvements for future iterations.

Manage database transactions for data consistency. Use when implementing ACID compliance, handling concurrency, or managing transaction isolation levels.

Benchmark customer MCSB compliance posture using three-state DMAIC backcasting: **Best Practice** (100% per domain), **Current State** (from pfc-grc-mcsb-assess), and **Desired Destination** (custo...

Filters a placement report to find URLs containing 'game', 'puzzle', or 'mobile' to add to your exclusion list.

Comprehensive toolkit for validating, linting, testing, and analyzing Helm charts and their rendered Kubernetes resources. Use this skill when working with Helm charts, validating templates, debugging chart issues, working with Custom Resource Definitions (CRDs) that require documentation lookup, or checking Helm best practices.

Edit, create, rename, and refactor C# code in Unity projects using unity-cli.

Prepare R packages for CRAN submission by checking for common ad-hoc requirements not caught by devtools::check(). Use when: (1) Preparing a package for first CRAN release, (2) Preparing a package update for CRAN resubmission, (3) Reviewing a package to ensure CRAN compliance, (4) Responding to CRAN reviewer feedback. Covers documentation requirements, DESCRIPTION field standards, URL validation, examples, and administrative requirements.

Post-answer fact verification of a claim, article, social-media post, document, or report. Use to verify truth, detect misinformation, evaluate source credibility, compare competing sources, or audit factual errors. Produces a Fact-Check Card with verdict, evidence trail, credibility scores, and a Manipulation/Framing Score. Triggers on fact-check this, is this true, verify this claim, check the facts, compare these sources, audit the citations.

Step-by-step plan for deploying a Next.js app to Vercel

Blocks tokens, API keys, and passwords in versioned files

Generates API endpoints with Express.js following layered architecture patterns. Use it to implement RESTful endpoints with validation, centralized error handling, and separated business logic.

Use when the user wants to deeply learn a new topic from scratch. Runs a pre-interview (current knowledge, end-goal proficiency, depth, practice load, background, scope), researches online (articles, niche-influencer blogs, canonical docs, subtopic landscape), then produces a structured markdown course with mandatory visual diagrams, evidence-based learning-science features (retrieval practice, spaced callbacks, worked-example fading, concept ledger, jargon gate, analogy hygiene), and a self-contained interactive HTML mini-course. Triggers on /teach-me, "teach me about X", "I want to learn X", "deep dive on X", "create a course on X", "study X with me".

Compose state management with a strong state-hoisting preference for Kotlin Compose (Android, Multiplatform, Compose for Web). Use for refactors or new UI that needs clear state ownership, unidirectional data flow, saved state decisions, or guidance on remember/retain/rememberSaveable/rememberSerializable, and for designing stateless composables with event callbacks.

Use when writing or reviewing tests - covers test philosophy, condition-based waiting, mocking strategy, and test isolation

Two modes — (1) import credential JSON files into CLIProxyAPI/Quotio's auth dir, (2) add/update a custom provider (URL + key + models) in the config. Accepts file paths or "url=... key=... model=..." style args.

Use for unsafe Rust code review and FFI. Triggers: unsafe, raw pointer, FFI, extern, transmute, MaybeUninit, NonNull, SAFETY comment, undefined behavior

Use when creating, reviewing, or styling charts, graphs, dashboards, sparklines, or any data visualization. Applies to Recharts, ECharts, Chart.js, matplotlib, Plotly, seaborn, D3.js, and SVG. Enforces Tufte principles (data-ink ratio, direct labeling, range-frame axes) plus modern screen-first standards (accessibility, responsive, dark mode).

Remove git worktrees from .worktrees/ directory and clean up all traces. Use this when the user wants to delete a worktree they no longer need, with interactive selection if no worktree name is provided.

Produces credible case-study writeups, non-hallucinated data handling, and fact-check lists for WeChat tech posts. Use when the user needs a project recap, results narrative, citation guidance, or a “what to verify” checklist for tech/engineering WeChat public accounts (微信公众号).
