Prepare UX work for engineering by preserving user intent, behavior, states, design-system usage, accessibility requirements, dependencies, acceptance behavior, and unresolved questions. Use when a designer says "get this ready for engineering", needs a handoff, behavioral contract, implementation-ready ticket content, or wants to stop engineering from guessing.
Respond to questions from Han Feizi's perspective: calm analysis of rule of law and institutional design, realistic insight into power games, and the truth about human nature in allegorical satire. Use when the user explicitly asks for this figure's perspective, mentions "hanfeizi-perspective", or wants to apply its core methods to analyze a problem; do not trigger automatically for general questions.
Use alongside the `hardhat` skill when the project depends on `@nomicfoundation/hardhat-toolbox-mocha-ethers`. Covers the ethers helpers exposed on `network.create()`, contract interaction (`ethers.deployContract`, calling functions, `connect`), TypeChain-typed contract instances, and the chai matchers from `@nomicfoundation/hardhat-ethers-chai-matchers` (`.to.emit`, `.to.be.revertedWith*`, `.to.changeEtherBalance(s)`).
Use when planning tests for Arduino, ESP32, ESP32-S3, Pico, or Pico W firmware; deciding what can run off-target; using Wokwi or simulation; writing host fakes; or accepting a physical hardware feature without confusing compile proof with system proof.
Control the hinge (fold) angle of a foldable iPhone Simulator such as iPhone Duo. Use when you need to fold, unfold, half-open, or animate the fold of a running simulator, read its current hinge angle, or test how an app reacts to hinge and display changes.
Generate a structured interview scorecard and interview guide for any role. Use when asked to create a hiring rubric, interview scorecard, structured interview guide, or assessment criteria for a job. Produces a scorecard with competencies, behavioural questions, and scoring guidance.

Write prose that sounds authentically human rather than AI-generated. Use this skill whenever writing long-form content, emails, articles, reports, documentation, blog posts, creative writing, social media copy, proposals, memos, or any text where sounding like a real person matters. Triggers on requests like "write this naturally," "make it sound human," "don't sound like AI," "write like a real person," or any writing task where the user has indicated they want authentic, non-robotic prose. Also use when editing existing text to remove AI-sounding patterns.
Edit user-facing prose into direct, natural language while preserving meaning, exact tokens, and the author's voice. Load only on an explicit invocation: a direct user request including the /humanize command, or an explicit text-preparation step of another skill's workflow. Drafting an ordinary reply, status, or explanation never activates this skill by itself. Follow the language of the latest request. Russian discovery terms: естественный русский текст.
Detect Cobalt Strike beacon command-and-control traffic using default TLS certificate signatures (serial 8BB00EE), JA3/JA3S/JARM fingerprints, HTTP malleable C2 profile pattern matching, and beacon jitter/interval analysis, built with Zeek network logs, Suricata IDS rules, and Python PCAP analysis. Use when hunting for Cobalt Strike beacon callbacks in network traffic or building detection rules for this C2 framework.
Detect data-staging activity (MITRE ATT&CK T1074) by analyzing EDR/Sysmon process-creation and file-system telemetry (Event ID 4688, Sysmon 1/11) for 7-Zip/RAR/tar archive creation, unusual temp or hidden folder access, and anomalous consolidation of files from multiple directories. Use when hunting for pre-exfiltration staging behavior, building detection rules for archiver abuse, or validating monitoring coverage for T1074.
Hunts for adversary persistence and execution via Windows scheduled tasks (T1053.005) by analyzing Security Event ID 4698 task-creation events, suspicious task properties, and unusual execution patterns from schtasks.exe/at.exe. Use after detecting schtasks or at.exe in process creation logs, during incident response to enumerate persistence on compromised hosts, or when Event ID 4698 fires for an unusual task.
Analyze PMCC (Poor Man's Covered Call / diagonal spread) positions from IB portfolio. For each diagonal spread, reports short leg risk (delta, IV, assignment probability), daily P&L projections, top-3 roll candidates, and a side-by-side comparison table. Requires TWS or IB Gateway running locally.
Get animated video clips ready to post, without touching a single slider. Upload your static images (JPG, PNG, WEBP, HEIC, up to 200MB), say something like "compare top image-to-video AI models and generate a clip from my photo", and download 1080p MP4 when it's done. Built for AI enthusiasts, marketers, content creators who move fast and want to find the best-performing image-to-video model before committing to one.
Arrange images or PDF pages into an A4 PDF, crop scrolling document screenshots to the original page boundaries, or convert continuous long images into long-page PDFs. Use this skill when the user needs screenshots merged into a PDF, phone UI and adjacent pages cropped out of court transcript screenshots, or each page to contain only its own content. Do not use for OCR, editing PDF text, or standalone image format conversion
This skill should be used when implementing Android code in Bitwarden. Covers critical patterns, gotchas, and anti-patterns unique to this codebase. Triggered by "How do I implement a ViewModel?", "Create a new screen", "Add navigation", "Write a repository", "BaseViewModel pattern", "State-Action-Event", "type-safe navigation", "@Serializable route", "SavedStateHandle persistence", "process death recovery", "handleAction", "sendAction", "Hilt module", "Repository pattern", "implementing a screen", "adding a data source", "handling navigation", "encrypted storage", "security patterns", "Clock injection", "DataState", or any questions about implementing features, screens, ViewModels, data sources, or navigation in the Bitwarden Android app.
Translates game design prose into engine-neutral implementation invariants and validation checks. Use when implementing or reviewing game mechanics where idle, hold-only, mashing, spam, safe waiting, or repeated scoring pulses must be prevented from dominating skilled play.
Implements the Schnorr identification protocol and a simplified Zero-Knowledge Password Proof (ZKPP) over the discrete logarithm problem, letting a prover authenticate by demonstrating knowledge of a secret without ever revealing it to the server. Use when designing or building password-less or password-secret-free authentication, or when a server must verify a user's credential without learning or storing the underlying secret.
