airflow-state-store
astronomer/agents
Persists task and asset state across retries and DAG runs using Airflow 3.3's AIP-103 key/value stores (`task_state_store`, `asset_state_store`) and the crash-safe `ResumableJobMixin`. Use when the user asks about task state store, checkpointing in tasks, persisting state across retries, job IDs surviving worker crashes, watermarks, asset metadata, resumable tasks, crash-safe operators, or "what's new in Airflow 3.3". Also use proactively when reading a DAG that uses Variables or XCom for intra-task coordination state — flag the anti-pattern and recommend task_state_store or asset_state_store instead. Also use proactively when reviewing ANY DAG that submits a job to an external system and waits for it to finish — Databricks, Snowflake, BigQuery, Redshift, Spark, dbt Cloud, EMR, AWS Batch, etc. — whether that is one submit-and-wait operator or split across a separate submit task plus a sensor/polling task; this covers `wait_for_termination`, `deferrable`, `durable`, hand-rolled sensors polling a run/job id, and whether to collapse a submit+sensor split into one task. The `task_state_store`/`asset_state_store`/`ResumableJobMixin` state-persistence pieces require Airflow 3.3+; the submit+poll architecture guidance itself applies on any Airflow version — do not skip this skill for a pre-3.3 DAG.
clean-names
ertugrul-dmr/clean-code-skills
Use when naming, renaming, or fixing names of variables, functions, classes, or modules in Python. Enforces Clean Code principles—descriptive names, appropriate length, no encodings.
accessibility
dralgorhythm/claude-agentic-framework
Ensure digital accessibility. Use when designing for accessibility, auditing WCAG compliance, or implementing a11y features. Covers WCAG 2.1 guidelines.
email-subject-line-optimizer
nicepkg/ai-workflow
A/B test subject line variations using proven copywriting frameworks. Predict open rates based on historical performance.
figma-audit-accessibility
southleft/figma-console-mcp-skills
Deep accessibility scorecard for a single Figma component or component set — state coverage (default/hover/focus/disabled/error/active/loading), focus-indicator quality and contrast, non-color state differentiation, target size, annotation completeness, and color-blind simulation (protanopia/deuteranopia/tritanopia), all rolled into per-category 0–100 scores and prioritized recommendations. Use when the user wants to vet ONE component before shipping it: triggers 'audit this component', 'accessibility score for this button', 'is this component set accessible', 'check the states on this component', 'does my button have a focus state', 'color blind check', 'rate this component for a11y', 'component accessibility scorecard'. Works on ANY Figma plan. For a broad sweep over a whole page/frame use figma-lint-design; for CODE-side (HTML) checks use figma-scan-code-accessibility.
k8s-timezone-config
julianobarbosa/claude-code-skills
Configure timezone for Kubernetes pods using TZ environment variable. Use when deploying workloads that need Brazil/São Paulo timezone or when logs show UTC (+0000) instead of local time.
analyzing-experiment-session-replays
posthog/skills
Analyze session replay patterns across experiment variants to understand user behavior differences. Use when the user wants to see how users interact with different experiment variants, identify usability issues, compare behavior patterns between control and test groups, or get qualitative insights to complement quantitative experiment results.
figma-import-tokens
southleft/figma-console-mcp-skills
Push design tokens from code INTO Figma as variables — DTCG / tokens.json / a token object → Figma variable collections, modes, and values. Use when the user wants to sync tokens code→Figma: triggers 'import tokens into Figma', 'create Figma variables from my tokens.json / DTCG / Tailwind config', 'sync design tokens to Figma', 'push tokens to Figma'. Non-destructively matches existing variables (by saved id/key/name) so re-imports update instead of duplicating. Works on ANY Figma plan. For the reverse (Figma → code) use figma-export-tokens.
genvarloader
mcvickerlab/genvarloader
Use when writing or reading GenVarLoader (gvl) datasets — preparing VCF/PGEN/SVAR variant sources with bcftools/plink2, calling gvl.write, configuring gvl.Dataset for haplotype/reference/annotated/variants output modes, attaching BigWig or Table tracks, setting up spliced haplotypes from a GTF, choosing track insertion-fill strategies for indels, or filtering variants by allele frequency.
syncfusion-angular-calendars
syncfusion/angular-ui-components-skills
Comprehensive guide for implementing Syncfusion Angular Calendar components including Calendar, DatePicker, DateRangePicker, DateTimePicker, and TimePicker. Covers installation, data binding, date/time selection, range selection, formatting, localization, masking, validation, customization, templates, accessibility, and controlled component patterns in Angular applications.
figma-manage-variables
southleft/figma-console-mcp-skills
Create, update, rename, delete, and organize Figma variables, collections, and modes — including fast batch create/update, setting scopes, code syntax, and adding theme modes. Use for incremental variable work: triggers 'create a variable', 'batch update variables', 'add a dark mode to my collection', 'rename this variable', 'set variable scopes', 'delete a variable/collection', 'add a mode'. Works on ANY Figma plan. For a from-scratch system use figma-setup-design-tokens; for code↔Figma sync use figma-import-tokens / figma-export-tokens.
asset-manager
oakoss/agent-skills
Organize design assets, optimize images and fonts, maintain brand asset libraries, implement version control for assets, and enforce naming conventions. Use when optimizing images for web, converting fonts to WOFF2, organizing asset directories, setting up responsive image pipelines, or managing logo variants.
email-notifications
serac-labs/serac
Create ServiceNow sysevent_email_action notifications — templates with substitution variables, mail scripts for dynamic content/recipients/attachments, custom events, weights, and digest configuration.
code-map-visualization
pproenca/dot-skills
Rendering and perception layer for codebase-as-geohash-map visualisations — choosing what to encode on colour/size/position, picking perceptually honest colour scales (viridis/OKLCH, not rainbow), drawing tens of thousands of cells on Canvas2D + WebGL/deck.gl inside a 16ms frame budget, placing and decluttering labels, GPU or spatial-index picking, camera animation and level-of-detail crossfades, and keyboard plus screen-reader accessibility for the canvas. Sits on top of geohash-spatial-code-maps, which owns the geohash encoding, projection, tiling, and navigation math. Also covers nature-inspired rendering — Voronoi, circle packing, phyllotaxis, metaball hulls, edge bundling. Trigger even when the user does not say "visualisation" — if the work involves drawing, colouring, labelling, animating, or making navigable a code map, spatial heatmap, or large cell/point layer on the web, this is the skill.
deterministic-metric-design
pproenca/dot-skills
Inventing deterministic metrics — turning a fuzzy property like 'maintainability', 'risk', or 'how reducible this code is' into a deterministic, computable number an agent can trust and optimize. Covers the path from construct to adoption — operationalizing the construct, confronting computability limits (Kolmogorov, Rice) with sound proxies, picking the right measurement scale, proving properties (monotonicity, invariance, the Weyuker/Briand axioms), guaranteeing determinism, establishing construct validity (not just LOC in disguise), and hardening against Goodhart-style gaming when an agent optimizes the metric. Trigger when designing, reviewing, or validating a quantitative metric, score, measure, or index — and even when the user doesn't say 'metric' but wants to quantify, score, rank, or measure code/behavior, build a deterministic optimization target, or invent a measure for something previously unquantified (e.g., behavior-preserving codebase-size reduction).
figma-analyze-component-set
southleft/figma-console-mcp-skills
Analyze a Figma COMPONENT_SET as a state machine for code generation — extract variant axes (state/size/etc.), map state variants to CSS pseudo-classes (hover→:hover, focus→:focus-visible, disabled→:disabled, error→[aria-invalid]), and compute per-variant visual diffs (only what changes per state). Use when generating an interactive component from a Figma variant set — triggers: 'analyze this component set', 'turn these variants into CSS states', 'generate a button/input/checkbox from Figma variants', 'what changes between the hover and default state', 'map Figma variants to component props', 'extract the state machine for this component'. Resolves bound variables to token names. NOT covered by the native MCP's get_design_context/get_metadata, which don't give you a variant-axis→CSS-state machine.
figma-generate-component-doc
southleft/figma-console-mcp-skills
Generate complete Markdown documentation for a Figma component — anatomy/layer tree, design tokens (colors, spacing, typography), states/variants matrix, accessibility notes, content guidelines, and optional code-parity + YAML frontmatter. Use when the user wants a docs page or handoff spec for a component or component set. Triggers: 'document this component', 'generate component docs/spec', 'create a docs page for the Button', 'write up the anatomy and variants', 'component handoff doc from Figma', 'turn this component into Markdown docs'. Reads the node tree, bound variables/tokens, and designer annotations, then the agent assembles Markdown. Requires the Figma Desktop app (Plugin API).
webconsulting-branding
dirnbauer/webconsulting-skills
Applies the current webconsulting.at design system: borderless square surfaces, Hanken Grotesk typography, teal/ink color tokens, invoice-led information hierarchy, a header-only brand notice, logo-first project icons, MDX patterns, dark mode, accessibility, and shadcn/ui integration. Use when building or reviewing webconsulting.at pages, internal tools, tracker/GitLab themes, project catalogs, TYPO3 templates, brand assets, or visual consistency.

android-ux
rcosteira79/android-skills
Use when designing or reviewing Android UI — applies Material Design 3 UX principles covering touch targets, spacing, navigation patterns, accessibility, animation timing, and platform conventions. Includes an M3 compliance audit that scores screens across 10 categories. Complements the compose skill with design-level decisions.
uifork
sambernhardt/uifork
Install and work with uifork, a CLI tool and React component library for managing UI component versions. Use when the user wants to version components, test UI variations, gather stakeholder feedback, or work with uifork commands like init, watch, new, fork, promote.
yc-apply
pedronauck/skills
Guides a founder through the full Y Combinator batch application end-to-end. A 10-phase workflow that captures the live YC form, profiles the founders, stress-tests the idea via an embedded grill loop, runs a mandatory 5-agent parallel external research pass on the startup, drafts every form field with anti-pattern and accepted-example checks, produces founder-video bullet notes (no script), runs a final adversarial gate, generates paste-ready submission answers, unlocks an interview-prep simulator after invite, and supports reapplicant delta tracking and post-decision post-mortems. Writes a documented markdown trail under a user-chosen workspace. Use when a founder wants to prepare a YC batch application, build their founder video, drill mock YC interview questions, or reapply with delta evidence. Don't use for pitch-deck design unrelated to YC, generic startup advice without applying, or post-funding work.
figma-annotations
southleft/figma-console-mcp-skills
Read and write designer annotations on Figma nodes — node-level design specs that pin properties (fills, width, fontSize, etc.) and carry plain or markdown notes. Use when the user wants to document or inspect interaction specs, animation timings, easing, accessibility requirements, or implementation notes attached directly to a node. Triggers: 'add an annotation', 'annotate this node/component', 'read the annotations on…', 'what specs are pinned to this element', 'list annotation categories', 'document the focus behavior on this button in Figma'. Annotations are distinct from comments (they pin to design properties) and from the description field. Requires the Figma Desktop app (Plugin API).
figma-deep-component
southleft/figma-console-mcp-skills
Extract a single Figma component (or any node) as a full recursive tree to N levels deep — every child's layout, fills/strokes/effects, typography, resolved bound variables (token names + code syntax), INSTANCE mainComponent references, prototype reactions, and annotations. Use when you need maximum-fidelity data to generate production code for ONE component — triggers: 'get the full component tree', 'deep extract this component', 'give me everything about this node for code gen', 'resolve all the tokens in this component', 'what instances does this component nest', 'extract reactions/prototype links', 'high-fidelity component spec'. Resolves bound variables to token names on ANY plan. Far deeper than the native MCP's get_design_context / get_metadata.
figma-library-variables
southleft/figma-console-mcp-skills
Discover and import design tokens from SUBSCRIBED Figma team libraries into the current file. Use when the user wants to reuse tokens that live in a shared library: triggers 'list library variables', 'what tokens are in our shared library', 'import a variable from our design system library', 'pull in the brand color token from the library'. Works on ANY plan via the Plugin API teamLibrary methods. For LOCAL variables use figma-export-tokens / figma-manage-variables.
figma-scan-code-accessibility
southleft/figma-console-mcp-skills
Scan generated/authored HTML for accessibility violations with axe-core (Deque) running over JSDOM — structural and semantic rules: ARIA attributes and roles, accessible names, alt text, form labels, heading order, landmarks, semantic HTML, tabindex, duplicate IDs, lang attribute, and ~50 more. Use on the CODE side of a Figma-to-code workflow: triggers 'scan this HTML for accessibility', 'run axe on my component', 'check the generated code for a11y', 'axe-core scan', 'accessibility lint my markup', 'WCAG check on code', 'is this HTML accessible'. This is a standalone Node script — NO Figma connection required. Visual rules (color-contrast, focus-visible, link-in-text-block, target-size) are DISABLED because JSDOM has no layout — use figma-lint-design for visual a11y on the design side. The two together give full design+code coverage.
recharts-patterns
yonatangross/orchestkit
Data visualization with Recharts 3.x including responsive charts, custom tooltips, animations, and accessibility for React applications. Use when building charts or dashboards with Recharts.
scvi-tools

figma-component-properties
southleft/figma-console-mcp-skills
Add, edit, and delete Figma component properties (TEXT, BOOLEAN, INSTANCE_SWAP, VARIANT) on a COMPONENT or COMPONENT_SET, and instantiate a component then set its instance properties. Use when authoring or wiring up a component's API in Figma — triggers: 'add a component property', 'add a boolean prop to this component', 'make this text a component property', 'add an instance-swap slot', 'create a variant property', 'rename/delete a component property', 'place an instance of this component', 'instantiate this component and set its label/state', 'set properties on this instance'. Properties must be added to the parent COMPONENT_SET, not individual variants. NOT covered by the native MCP's read-only get_design_context/get_metadata.
opquast-digital-quality
mgifford/accessibility-skills
Apply the Opquast Digital Quality Framework (245 rules, 14 categories) when building, reviewing, or auditing websites and web applications. Use for web development quality assurance, accessibility compliance, security hardening, privacy implementation, e-commerce best practices, and holistic digital quality checks.
spree-catalog

Common phrasings include "add a product type", "variants vs options", "product taxonomy", "categorize products", "product images", "Meilisearch reindex", "search broken", "product not showing in store", "publish product on channel", "master variant", "default variant", "SKU". Provides the catalog graph and the operations on it; defers to local @spree/docs for field-level detail.
figma-arrange-component-set
southleft/figma-console-mcp-skills
Organize a Figma COMPONENT_SET's variants into a clean, labeled grid — rows and columns derived from the variant properties, with row labels on the left, column headers on top, and a titled white container. Use when a variant set is a messy pile and you want a presentable, documentation-ready layout — triggers: 'arrange my variants in a grid', 'organize this component set', 'lay out the variants with labels', 'make a variant matrix', 'clean up my component set layout', 'add row/column headers to my variants'. Picks the last property (usually State) as columns and the rest as rows by default. NOT something the native MCP's read-only tools do — this writes a new organized layout to the canvas.
design-tokens
laurigates/claude-plugins
Design tokens and CSS custom properties: theme systems, dark mode, component libraries. Use when implementing design systems or user mentions tokens, CSS variables, or theming.
content-writer
majesticlabs-dev/majestic-marketplace

Analyse the language demands of a classroom task to identify barriers for EAL and multilingual learners. Use when adapting tasks, planning support, or assessing linguistic accessibility.
expo-design-system-scaffolder
pproenca/dot-skills
Scaffolds Expo / React Native design system components that obey the expo-design-system rules by construction — a variant-driven pressable primitive, a slot-based card surface, a typed text primitive, a labeled form field, a FlashList entity screen, a theme token group, and a Storybook variant catalog. Generated code uses Unistyles v3 variants instead of style props, ref-as-prop, design tokens, built-in accessibility, and web/iOS parity (`_web` hover/focus/cursor on interactive primitives), so it follows expo-design-system without rework. Output is TSX/TS using react-native-unistyles. Trigger whenever the user wants to create, add, generate, or scaffold a new shared UI component, primitive, design token group, or screen for the clinic mobile app — even if they don't mention the design system.
code-distill
pproenca/dot-skills
On-demand pattern extraction from a specific GitHub codebase, given a focused query — "how does shadcn/ui implement the design system", "how does opencode use effect-ts", "how does base-ui handle composition" — when no pre-distilled static rule pack exists yet. Distills the generic pattern-extraction moves — classify the query before grepping (component / composition / state / effect / error / build / routing), grep before reading whole files, treat tests and examples/ as canonical intent, follow imports outward for the public surface, follow usages inward for variants, filter boilerplate / legacy / test scaffolding to surface load-bearing code, and capture findings to /knowledge/libraries/ for reuse. Dynamic light sibling of static code-atlas skills (opencode-ts, openai-codex-rust-patterns, nextjs-ppr-patterns). Triggers on "show me how <library> implements X", "find the <pattern> in <repo>", "distill <library>", and ad-hoc /distill-<library>-style invocations.
spree-data-model
spree/agent-skills
Use when the user is asking how Spree's domain models relate — Orders, LineItems, Variants, Products, Stores, Channels, Markets, Payments, Shipments, Customers, Adjustments. Architecture and relationships only. Common phrasings include "how does X connect to Y", "what's the relationship between", "where does Spree store X", "how do I query orders across stores", "how do channels work", "what's the difference between Cart and Order", "Store vs Channel vs Market". For adding new models / new API resources, use the `spree-resource` skill. For field-level detail, see `docs/developer/core-concepts/` in the installed `@spree/docs` package.
spree-pricing
spree/agent-skills
Use when the user is working with Spree pricing — variant prices, currency-specific pricing, sale/compare-at prices, price lists (5.3), price rules, EU Omnibus compliance (PriceHistory + prior_price), tax-inclusive pricing. Common phrasings include "set price", "compare at price", "sale price", "price list", "multi-currency pricing", "prior price", "Omnibus", "EU pricing law", "lowest price in 30 days", "tax inclusive", "VAT". Provides the price graph and the regulatory bits.
variation-theory-task-designer

metric-validation-harness
pproenca/dot-skills
Empirically validates a software metric before trusting or optimizing it — point it at any candidate metric (a command that takes a path and prints one number) plus a corpus, and it runs experiments that try to falsify each property a good metric must have. Checks determinism (same input, same number across runs and hash seeds), invariance to cosmetic edits (also an anti-gaming probe), monotonicity under construct-increasing edits, discrimination, robustness on edge inputs, near-linear tractability, and construct validity (convergent, discriminant vs LOC, predictive AUC, lift over a baseline). Trigger whenever someone proposes, reviews, tunes, or ships a metric, score, or index, asks "is this metric any good", suspects a score tracks LOC or jumps between runs, or builds a deterministic optimization target. It is the empirical companion to the deterministic-metric-design skill and is read-only.
webflow-mcp:accessibility-audit
