Convert Markdown documents to professionally styled DOCX (Word) files with python-docx. Handles CJK/Latin mixed text, fenced code blocks, tables, blockquotes, cover pages, TOC field, watermarks, and page numbers. Supports multiple color themes matching any2pdf (Warm Academic, Nord, GitHub Light, etc.) and is battle-tested for Chinese technical reports. Use this skill whenever the user wants to turn a .md file into a styled Word document, generate an editable report from markdown, or create a DOCX from markdown content — especially if CJK characters, code blocks, or tables are involved. Also trigger when the user mentions "markdown to docx", "md2docx", "any2docx", "md转word", "md转docx", "生成word", or asks for an "editable document" from markdown source.
Use Mergify stacks for git push, commit, branch, and PR creation in a repository that uses Mergify stacks (its stack commit-msg hook is installed, or its recent commits carry `Change-Id` trailers). In such a repository, ALWAYS use this skill when pushing code, creating commits, creating branches, or creating PRs. In any other repository, use plain git and gh instead. Triggers on push, commit, branch, PR, pull request, stack, stacked, git, rebase, checkout, reorder, move, sync, amend, note, revision history

Design and implement Minimal APIs in ASP.NET Core using handler-first endpoints, route groups, filters, and lightweight composition suited to modern .NET services. USE FOR: building new HTTP APIs in ASP.NET Core; creating lightweight microservices; choosing between Minimal APIs and controllers. DO NOT USE FOR: unrelated stacks; generic tasks that do not need this specific guidance. INVOKES: inspect the repository context, edit targeted files, and run relevant build, test, lint, or validation commands when changes are made.
Use this skill when visual quality and design identity matter for a PDF. CREATE (generate from scratch): "make a PDF", "generate a report", "write a proposal", "create a resume", "beautiful PDF", "professional document", "cover page", "polished PDF", "client-ready document". FILL (complete form fields): "fill in the form", "fill out this PDF", "complete the form fields", "write values into PDF", "what fields does this PDF have". REFORMAT (apply design to an existing doc): "reformat this document", "apply our style", "convert this Markdown/text to PDF", "make this doc look good", "re-style this PDF". This skill uses a token-based design system: color, typography, and spacing are derived from the document type and flow through every page. The output is print-ready. Prefer this skill when appearance matters, not just when any PDF output is needed
Analyze, intercept, and replay HTTP/HTTPS traffic through mitmproxy. Gives you 20 MCP tools for traffic analysis, request replay, interception control, and proxy configuration. Use when debugging APIs, testing security, or understanding how an application talks to its backend.
Build and query managed search indexes (Stores) using the Mixedbread Python and TypeScript SDKs. Use when creating knowledge bases, uploading documents, performing semantic or vector search, asking questions over documents, using agentic multi-step retrieval, combining store search with web results, filtering by metadata, reranking, or discovering metadata facets.
Audit an existing React Native / Expo app's design - run the AI-tells grep checklist, inspect screens against a ten-category rubric, Trunk Test each screen, and produce impact-rated findings with a Design Score and an AI Slop Score plus a regression baseline. Report-only by default; opt-in fix mode. Use when asked to review, audit, critique, or QA an app's design or UI quality. For building new screens use mobile-taste; for actually redesigning use mobile-redesign-screen or mobile-redesign-app.
Use this skill to wire MockK (the Kotlin-first mocking framework) into a JVM unit-test suite, especially when coroutines, singleton/`object` mocking, or constructor mocking dominate. Covers `io.mockk:mockk-jvm:1.14.x` (and `mockk-android` + `mockk-agent` for instrumented), `every { } returns`, `coEvery` / `coVerify` (native suspend support — the big win over Mockito), `mockk(relaxed = true)` / `relaxUnitFun = true`, `slot<T>()` capture, `verifySequence` / `verifyOrder` / `confirmVerified`, `mockkStatic` / `mockkObject` / `mockkConstructor` with `unmockkAll()` cleanup, `@MockK` / `@RelaxedMockK` / `@SpyK` / `@InjectMockKs` annotations, and the Mockito-vs-MockK decision criteria. Use when the user mentions `coEvery`, `mockkObject`, `mockkStatic`, `slot`, `MockKException`, `every returns vs coEvery`, `relaxed = true`, or asks how to mock a Kotlin `object`/singleton.
Use MQTTX CLI for MQTT connections, publishing and subscriptions, MQTT 5 features, TLS and SCRAM authentication, payload codecs and schemas, benchmarks, built-in or custom data simulation, configuration, installation and troubleshooting. Use when operating or testing MQTT through the mqttx command. Does not operate MQTTX Desktop or administer a broker.
Use this skill when the user wants to build a new plugin that extends Nebula Logger - for example, custom trigger handlers on `LogEntryEvent__e` / `Log__c` / `LogEntry__c`, custom purge actions, or Slack-style outbound integrations. Covers the plugin framework interfaces, `LoggerPlugin__mdt` configuration, package layout, and testing considerations.
E-coupon and merchant domain (coupon): the full loop of adding/updating/freezing/deleting and querying merchants (trader), creating e-coupon templates, selling coupons to merchants, issuing coupons to vehicles, and querying and recycling coupons. Use when the user wants to run merchant operations for parking coupons/coupons, or handle coupon issuance-redemption-recycling. Actual fee queries/payments after coupon deduction are in the trade domain (openydt-billing).
Operate Orca-managed worktrees, folder contexts, terminals, repos, automations, artifacts, skill sharing, worktree comments, and Orca's embedded browser through the `orca` CLI. Use when the user says "$orca-cli", "Orca worktree", "child worktree", "spawn codex/claude in a worktree", "read/wait/send Orca terminal", "handoff" / "handover" / "give this to another agent", "Orca browser", "orca artifacts", or "share skills". Prefer it over raw git worktree, ad hoc PTYs, or Computer Use when Orca state is involved. Use Computer Use only when a visible window needs GUI control that a CLI, filesystem, or API cannot do.
Build, coordinate, operate, troubleshoot, exercise, and improve an authorized Primary, Alternate, Contingency, and Emergency communications plan. Use for resilient emergency-communications paths and their ownership, triggers, check-ins, tests, and corrective actions. Do not use for generic incident status messaging, frequency or channel planning, radio programming, or unauthorized transmission and activation.
When the user wants help with paid advertising campaigns on Google Ads, Meta (Facebook/Instagram), LinkedIn, Twitter/X, or other ad platforms. Also use when the user mentions “PPC,” “paid media,” “ROAS,” “CPA,” “ad campaign,” “retargeting,” “audience targeting,” “Google Ads,” “Facebook ads,” “LinkedIn ads,” “ad budget,” “cost per click,” “ad spend,” or “should I run ads.” Use this for campaign strategy, audience targeting, bidding, and optimization.

Referee-side skill for Nature Portfolio manuscripts: write a referee report, inventory every ask and sub-ask in received comments, grade drafted replies, and test reply readability. Check methodology, statistics, reporting, reproducibility and data/code availability. Preserve referee wording, numbering and order; require one reply per ask with a direct opening answer and a manuscript location or explicit no-change rationale. Use for review this manuscript, what will reviewers attack, turn comments into a checklist, answer each comment, did I miss a point, would this reply satisfy the reviewer, 审稿、写审稿意见、模拟审稿、拆解审稿意见、逐个回复、逐条对照、有没有漏回、审稿人会不会接受、以审稿人视角检查回复、回复够不够直白. Use rebuttal-response to choose response stances, calibrate claims and assemble or audit the whole letter.
Runs the parallel-cli tool for web workflows: web search, URL and PDF extraction, deep research reports, structured data enrichment of supplied rows, FindAll entity discovery, and recurring web monitors. Prefers primary literature and institutional sources for scientific queries. Use when looking up current web evidence or a bounded research question. Use when fetching content from a known URL, PDF, or JavaScript-rendered page. Use when adding web-sourced fields to a list of companies, people, or products. Use when discovering entities that match natural-language criteria. Use when an explicitly exhaustive multi-source report is requested. Use when tracking web changes on a recurring schedule. Not for one-time checks of a known page that need no CLI, or for offline literature databases.

Auto-invoked when discussing payment card security, cardholder data protection, PCI compliance validation, or merchant/service provider assessment. Covers scope reduction strategies, SAQ vs ROC determination, compensating controls, customized approach, and the new targeted risk analysis requirements introduced in v4.0.
Update peon-ping configuration — volume, pack rotation, categories, active pack, and other settings. Use when user wants to change peon-ping settings like volume, enable round-robin, add packs to rotation, toggle sound categories, or adjust any config.
Use this skill when emitting inline review comments, whether posted to a GitHub pull request or written to a local file under caller-declared local-file output. Apply when formatting comments following Bitwarden engineering standards with severity emojis, clear explanations, and actionable suggestions. Use after findings are classified and ready to emit. DO NOT USE when posting summary comments.
Expert in legacy Windows PowerShell 5.1. Specializes in WMI, ADSI, COM automation, and maintaining backward compatibility with Windows Server environments. Use for Windows-specific automation on legacy systems. Triggers include "PowerShell 5.1", "Windows PowerShell", "WMI", "ADSI", "COM object", "legacy PowerShell".
Prepares a reproducibility artifact (code/data) for submission and badging. Use when a researcher says "artifact evaluation", "artifact appendix", "reproducibility", "badge", "Artifacts Available/Evaluated/Functional/Reusable", "Results Reproduced/Replicated", "ACM badging", "USENIX/OSDI/SOSP AE", "SIGMOD ARI", "NeurIPS code/checklist", "ACL repro checklist", "Zenodo DOI", "Software Heritage", "anonymize my code/repo", or "package my code". Builds the artifact README + appendix, the dependency/run instructions, an anonymized repo for double-blind, and archival-DOI (Zenodo version vs concept) / Software Heritage SWHID guidance; resolves the ACM badge taxonomy and the Reproduced/Replicated era swap; and lints the artifact directory against the ML Code Completeness checklist with bundled stdlib-only scripts. Outputs an artifact-readiness checklist + packaging plan. Re-verifies the venue current artifact rules live. Advisory only; never submits.
Step-by-step camera-ready prep for accepted papers — the error-prone final stage before publication. Use when a researcher says "camera-ready", "final version", or "my paper got accepted, now what", or mentions ACM eRights / rights form / TAPS / ORCID / DOI block, IEEE PDF eXpress / conference ID / eCF copyright form / Xplore, OpenReview final upload, de-anonymization, or extra camera-ready pages. Resolves the venue's rail from a machine-readable profile and walks it end to end across ACM eRights, ORCID, rights/DOI block, TAPS source upload, IEEE PDF eXpress, conference IDs, file naming, eCF exact-title match, registration/no-show, NeurIPS-style [final] recompile, and OpenReview upload. Generates an ordered checklist with deadlines and +page rules, and lints the final .tex for leftover anonymization and missing rights blocks via bundled stdlib-only scripts. Advisory — it prepares, explains, and lints, but never completes a form or submits anything.
Use when you need to turn selected modules (P0 first) into a single-page module SSOT at `.aisdlc/project/components/{module}.md`, and establish within that same page the authoritative entry point for API/Data contracts, an invariant summary, evidence entry points, and structured Evidence Gaps, to satisfy the Discover DoD gate.
Use when you already have a components map and several module pages, and now need to converge business modules (products<=6), fix the run/troubleshoot/rollback entry points (ops), and execute the DoD gate and incremental Discover (Delta Discover, stale expiry detection) to keep the knowledge base usable and maintainable.
Deploy the dispatcher PCF for a third-party `.ppmplugin` control to a Power Platform environment via `pac pcf push`. The dispatcher PCF is the Studio-side control that dispatches the composite key `<name>/<receiver>` over the wrap shell's `SendMessagePlugin` bridge to the control's native module. Verifies deploy prereqs (Node.js 20+ with npm, .NET SDK, and active `pac auth`), then three confirmation gates — publisher prefix (2–8 chars; defaults to `pamext` or the last-used value from `.extension-state.md`), version bump (patch / minor / major / no-bump), target environment URL (from `pac org who`). Builds the PCF if needed, then pushes. Decoupled from /generate-pcf-companion so the engineer can scaffold and customize locally, then deploy when ready. Updates `.extension-state.md` with deployment history (timestamp, env URL, version, prefix used).
Generate avatar images, surreal paper-art portraits, and reusable image prompts from the shared Punk style library for people, pets, objects, profile pictures, pet portraits, and keepsake cards. Use this skill to identify the subject from image or text, choose one avatar-capable style and any required style mode, compile the selected style atom into the avatar blueprint, save the final prompt, and generate the image when an image-generation tool is available.
Comprehensive mobile testing for iOS and Android platforms including gestures, sensors, permissions, device fragmentation, and performance. Use when testing native apps, hybrid apps, or mobile web, ensuring quality across 1000+ device variants.
