Development
Auto-generates professional README.md files for Arduino/ESP32/RP2040 projects following open-source best practices. Use when user wants to document their project for GitHub, needs help writing a README, or says "make my project shareable". Follows awesome-readme standards with sections for Overview, Hardware, Software, Setup, Usage, Troubleshooting, and Contributing.
Install and verify Runta tooling for a repository. Use when Codex needs to set up Runta for a user, install the Runta CLI or SDKs, choose the right package manager, check RUNTA_TOKEN, diagnose installation failures, or produce a clear installation report before running Runta workflows.
Design, implement, migrate, test, and operate Rust database access, including SQLx, Diesel, SeaORM, schema evolution, transaction boundaries, connection pools, retries, type mapping, concurrency control, and real-database verification. Use when users ask about Rust SQL or ORM code, migrations, transactions, PostgreSQL or MySQL integration, connection pools, query safety, or database production readiness.
Guided entry point for using Sentry through your agent. Orients you to your current setup and, for a new project, sets up Sentry end to end with sane defaults — provision a project, install the SDK (errors, tracing, and whatever it enables by default), and confirm real telemetry reaches Sentry. Routes other intents (adding more signals, fixing issues) to the right skill.
Execute approved, bounded work in an isolated implementation conversation and return a structured evidence receipt. Use with inherited history or an explicitly identified source; no particular planning, testing, or review skill is required.
Cut a release — detect versioning context, generate a changelog from conventional commits, bump versions, create a git tag, and optionally squash-merge to a release branch. Use when the user says "release", "cut a release", "tag a release", "bump the version", "create a changelog", "ship a version", "publish", or any variation of shipping/publishing a version. This skill is intentionally generic and works across any repo — it infers context from git history and project structure rather than assuming a specific setup. Supports the trunk+release branch model (ADR-013) when a `release` branch exists.
Comprehensive guide for implementing the Syncfusion Angular DateTimePicker component. Use this when working with combined date and time selection inputs, datetime formatting, or calendar-time pickers in Angular applications. Covers DateTimePicker API, events, styling, and localization patterns.
Implements the Syncfusion React PDF Viewer (PdfViewerComponent) for embedding, configuring, and loading PDF documents. Use this when rendering PDFs in a React application, embedding viewer controls, or generating TSX/HTML code for PDF display and interaction.
Drive a change through a red-green-refactor loop - failing test first, minimal code to pass, then clean up. Use when implementing a feature or fixing a bug where correctness matters and a test can pin the behavior. Says "TDD", "test first", "red green refactor", "write the test first".
Critique, audit, or score a Temporal workflow design for correctness, production readiness, and best-practice compliance. Use when asked to review a Temporal architecture, evaluate whether a design is production ready, identify anti-patterns or risks, assess Temporal fitness for a use case, or give a design a thumbs up/down. Not for writing or debugging Temporal code — use temporal-developer for that.
Apply the Theory of Constraints (Goldratt's Five Focusing Steps) to find and fix the single bottleneck that caps a process, workflow, pipeline, or Agent Skill/plugin's throughput. Use whenever optimizing speed, lead time, cost, or token/context budget of a system — CI/build pipelines, dev value streams (idea→review→merge→ship), an Agent Skill's trigger/context flow, or runtime code paths — ESPECIALLY when you don't know where to optimize, a local speedup didn't improve the whole, work piles up at a stage, everything is busy but little ships, adding capacity didn't help, or a policy/rule (not a resource) is the limiter. It locates the constraint with measurement, then prescribes exploit → subordinate → elevate → repeat, and stops you optimizing non-constraints (the "mirage of the non-bottleneck"). Trigger even when the user just says "speed this up", "why is this slow", or "make this more efficient" without mentioning constraints or bottlenecks.
Build a measured exposure and grading path in Three.js. Use for a 64x36 encoded luminance meter, asynchronous readback, weighted log-average exposure, asymmetric adaptation, single tone-map ownership, and a generated 32-cube post-tone-map LUT.

Use when building Mini Apps, using ZaUI components, calling Zalo APIs, integrating payments, converting web apps to Mini Apps, or following Zalo design standards.
Use when a problem or issue needs explicit framing before deeper analysis begins — establishing the Problem statement, Current state, Desired state, Stakeholders, and Success criteria. This should trigger when an issue's Problem Framing point of view needs evaluation, or when a maintainer directly asks to frame a problem before root-cause analysis, design, or planning begins. Part of Plinth Toolkit

Companion skill for the Building Filesystem Agents course on Vercel Academy. Use when the user mentions "filesystem agents", "the course", "teach me", or asks about ToolLoopAgent, Vercel Sandbox, or bash tools in the context of the Academy course.
Use this skill to get documentation for third-party APIs, SDKs or libraries before writing code that uses them to ensure you have the latest, most accurate documentation. This is a better way to find documentation than doing web search. This includes when a user asks for tasks like "use the OpenAI API", "call the Stripe API", "use the Anthropic SDK", "query Pinecone", or any other time the user asks you to write code against an external service and you need current API reference. Fetch the docs with chub before answering, rather than relying on your pre-trained knowledge, which may be outdated because of recent changes to these APIs. Be sure to use this skill when the user asks for the latest docs, latest API behavior, or explicitly mentions chub or Context Hub. Ensure `chub` is available, run `chub --help`, then follow the instructions there.
