framework-recipes
This skill should be used when the user asks for implementation recipes, examples, migration guidance, troubleshooting, or best practices for specific TUI frameworks and libraries: Rust Ratatui/Crossterm/Termion/Cursive, Python Textual/Rich/prompt_toolkit/curses/Urwid/asciimatics, Go Bubble Tea/Lip Gloss/Bubbles/tview/tcell/termui/gocui, Node Ink/Blessed/Inquirer/Prompts, .NET Terminal.Gui/Spectre.Console, C/C++ ncurses/notcurses/FTXUI, Zig vaxis, and SwiftTUI. PROACTIVELY activate for: framework-specific app structure, cleanup, testing, widgets, migration, library comparison, framework troubleshooting, API gotchas, and porting between TUI frameworks. Provides: framework defaults, gotchas, testing hooks, and selection recipes.
What this skill does
# Framework Ecosystem Recipes Use this skill when the user names a specific terminal UI framework or needs practical ecosystem guidance. Fetch current official docs when exact API syntax or version-specific behavior matters. ## Rust recipes **Ratatui + Crossterm** is the modern default for Rust full-screen TUIs. Structure apps around explicit state, event handling, and rendering functions. Use Crossterm for cross-platform terminal setup and events. Snapshot widgets at fixed sizes and integration-test the event loop through a PTY. Guidelines: - Keep terminal setup/cleanup in one guard. - Render from immutable state where possible. - Use constraints and layout primitives instead of absolute coordinates. - Treat panics as terminal-cleanup events. ## Python recipes **Textual** fits substantial apps with widgets, CSS-like styling, workers, and test automation. **Rich** fits rich output, progress, markdown, tables, panels, and logging. **prompt_toolkit** fits shells, REPLs, completions, multiline editing, and custom key bindings. **curses/ncurses** fits classic dependency-light TUIs with careful cleanup. Guidelines: - For curses, use wrapper/finally cleanup and remember coordinates are y,x. - For Textual, separate app state from workers and test with framework-supported pilots. - For Rich, avoid full-screen complexity when rich scrollback output solves the problem. ## Go recipes **Bubble Tea** uses Elm-style `Model`, `Update`, and `View`. Pair with Bubbles for common controls and Lip Gloss for styles/layout. **tview** gives widget-rich apps over **tcell**. Use **tcell** directly for lower-level cell control. Guidelines: - Keep update logic pure where possible. - Send long work through commands/goroutines that return messages. - Test `Update` and `View` separately before PTY tests. ## Node and TypeScript recipes **Ink** is best for React-style terminal components, hooks, and component testing. **Blessed** fits DOM-like widget trees and manual screen lifecycle. Prompt libraries are often better than full-screen apps for short questionnaires. Guidelines: - Verify resize, mouse, and Windows behavior for the exact library version. - Keep side effects out of render functions. - Use PTY integration tests for flows that depend on terminal behavior. ## .NET recipes **Terminal.Gui** fits full-screen applications with views, keyboard navigation, mouse, themes, and layout. **Spectre.Console** fits rich CLI output, prompts, progress, status, trees, tables, and command app composition. Guidelines: - Choose Spectre.Console before Terminal.Gui when the UI can remain line-oriented. - Abstract console I/O for tests. - Provide non-interactive command equivalents for automation. ## C/C++, Zig, and Swift recipes **ncurses** remains the classic portable C TUI layer. **notcurses** is useful for modern visuals, rich cells, images where supported, and high-performance terminal graphics with fallbacks. **FTXUI** offers composable C++ components and layout. **zig-vaxis** is a modern Zig TUI toolkit with Unicode-aware terminal handling. **SwiftTUI** and related Swift terminal libraries fit Swift-native CLIs, but verify platform and terminal coverage carefully. Guidelines: - Low-level frameworks demand explicit cleanup, Unicode measurement, and capability fallback tests. - Prefer maintained libraries with documented Windows, tmux, and Unicode behavior. - Avoid image/graphics features as hard requirements unless the deployment terminal is controlled. ## Reference files - `references/rust-python-go.md` - Practical patterns for Ratatui, Textual/Rich/prompt_toolkit/curses, Bubble Tea/tview/tcell. - `references/node-dotnet-and-selection.md` - Ink, Blessed, Terminal.Gui, Spectre.Console, migration, and selection gotchas. - `references/low-level-and-emerging.md` - C/C++ ncurses/notcurses/FTXUI, Zig vaxis, SwiftTUI, and emerging toolkit cautions.

jfrog
IncludedInteract with the JFrog Platform via the JFrog CLI and REST/GraphQL APIs. Use this skill when the user wants to manage Artifactory repositories, upload or download artifacts, manage builds, configure permissions, manage users and groups, work with access tokens, configure JFrog CLI servers, search artifacts, manage properties, set up replication, manage JFrog Projects, run security audits or scans, look up CVE details, query exposures scan results from JFrog Advanced Security, manage release bundles and lifecycle operations, aggregate or export platform data, or perform any JFrog Platform administration task. Also use when the user mentions jf, jfrog, artifactory, xray, distribution, evidence, apptrust, onemodel, graphql, workers, mission control, curation, advanced security, exposures, or any JFrog product name.
cupynumeric-migration-readiness
IncludedPre-migration readiness assessor for porting NumPy to cuPyNumeric. Use BEFORE substantial porting work begins when the user asks whether code will scale on GPU, whether they should migrate to cuPyNumeric, which NumPy patterns transfer cleanly, what must be refactored before porting, or mentions pre-port assessment, scaling analysis, or refactor planning. Inspect the user's source code, look up NumPy usage, cross-reference the cuPyNumeric API support manifest, and distinguish distributed-scaling-friendly patterns from blockers such as unsupported APIs, scalar synchronization, host round-trips, Python/object-heavy control flow, shape/data-dependent branching, and in-place mutation hazards. Produce a verdict of READY, LIGHT REFACTOR, SIGNIFICANT REFACTOR, or NOT RECOMMENDED, with concrete refactor pointers.
alibabacloud-data-agent-skill
IncludedInvoke Alibaba Cloud Apsara Data Agent for Analytics via CLI to perform natural language-driven data analysis on enterprise databases. Data Agent for Analytics is an intelligent data analysis agent developed by Alibaba Cloud Database team for enterprise users. It automatically completes requirement analysis, data understanding, analysis insights, and report generation based on natural language descriptions. This tool supports: discovering data resources (instances/databases/tables) managed in DMS, initiating query or deep analysis sessions, real-time progress tracking, and retrieving analysis conclusions and generated reports. Use this Skill when users need to query databases, analyze data trends, generate data reports, ask questions in natural language, or mention "Data Agent", "data analysis", "database query", "SQL analysis", "data insights".
token-optimizer
IncludedReduce OpenClaw token usage and API costs through smart model routing, heartbeat optimization, budget tracking, and native 2026.2.15 features (session pruning, bootstrap size limits, cache TTL alignment). Use when token costs are high, API rate limits are being hit, or hosting multiple agents at scale. The 4 executable scripts (context_optimizer, model_router, heartbeat_optimizer, token_tracker) are local-only — no network requests, no subprocess calls, no system modifications. Reference files (PROVIDERS.md, config-patches.json) document optional multi-provider strategies that require external API keys and network access if you choose to use them. See SECURITY.md for full breakdown.
resend-cli
IncludedUse this skill when the task is specifically about operating Resend from an AI agent, terminal session, or CI job via the official resend CLI: installing/authenticating the CLI, sending/listing/updating/cancelling emails, batch sends, domains and DNS, webhooks and local listeners, inbound receiving, contacts, topics, segments, broadcasts, templates, API keys, profiles, or debugging Resend CLI/API failures. Trigger on mentions of Resend CLI, `resend`, `resend doctor`, `resend emails send`, `resend domains`, `resend webhooks listen`, `resend emails receiving`, or agent-friendly terminal automation.
alibabacloud-odps-maxframe-coding
