Collect Amazon product details by ASIN from Amazon — ASIN, title, price, rank, reviews, variants. Use when the user wants to look up product data directly by ASIN.
Use when designing or reviewing reusable Jetpack Compose component APIs with modifier parameters, root layout placement, caller-provided variable content, primitive content parameters, optional content, or boolean shape flags.
Generate and iterate on UI with 21st AI from the terminal via the `21st` CLI (`@21st-dev/cli`): sketch a UI from a prompt, preview the variants in the browser, edit any variant in place with a natural-language change, and pull the final code into the project. Use whenever the user wants to BUILD / SKETCH new UI ("sketch a pricing page", "generate a hero with 21st", "make me a <X> section"), ITERATE on a generated draft ("edit the third variant", "add a toggle to that take"), or GRAB the code of a draft ("pull that variant's code", "сгенери UI на 21st", "поправь третий вариант", "забери код того наброска"). For finding/installing existing components use the `21st-cli-use` skill; to publish your own, `21st-registry`.
One-shot brand-faithful presales redesign of a website page. The user provides only the URL; everything else — extraction, tension identification, three differentiated variants (one fully cinematic), validation — is derived from the captured brand surface. Use when the user asks to "uplift", "refresh", or "redesign a site for presales" without wanting to coordinate the extract / direct / prototype chain themselves.
Extract and structure design tokens from existing CSS, Tailwind config, Figma variables, or design descriptions. Use when asked to extract tokens, create a token system, audit design consistency, or migrate from hardcoded values to a token architecture. Outputs tokens in CSS custom properties, Tailwind config, and Style Dictionary JSON formats.
Use when writing, reviewing, or refactoring code, or scaffolding a new project. Language-agnostic principles (types encode invariants, parse don't validate, errors as values, no mocks, earn abstractions) with dialects for Rust, TypeScript, Go, and Python.
Effective Lua programming for FiveM - functions, tables, variables, conditionals, error handling. Use when writing or reviewing Lua code for FiveM resources.
Used to discover the minimal change that a target truly accomplishes: put identity, boundaries, quality, optimization metrics, and implementations in parentheses, keep only the concise core of 'who or what goes from A to B', compress it into the minimal structural formula of interpretable variables, verify whether it is truly decontextualized through cross-domain migration, and save it as a validated Org note. USE WHEN the user says '/ljg-is', 'What is the essence of X', 'The One', 'Find the essence of the target', 'Essence definition', 'Minimum function', 'What exactly is transformed into what', or asks to distinguish qualifiers from the core. NOT FOR asking about reasons (use ljg-think), seeking motifs or causal structures (use ljg-structure), or casually saying 'essentially' in a sentence.
Use when the user asks to "generate subject line variants", "pre-score my subject lines", or "will this subject get truncated / trigger spam filters"; produces a labeled subject + preheader variant set and a per-variant heuristic pre-score card — spam-trigger flags, length/truncation across desktop + mobile, emoji-count, and the inbox preview render (from-name + subject + preheader) — before any test is run. Not for the body copy or CTA — use email-creative-builder; not for the A/B test design or significance read — use send-experiment-designer; not for the profile-weighted EQS or the S1/S2/N1/D1 vetoes — use email-quality-auditor. 邮件主题行生成/主题行预打分/截断与垃圾词检查
Use when the user asks to "personalize the email", "add merge tags / dynamic content", "set up conditional blocks per segment", or "make first-name and product-recommendation fields fall back safely"; produces a merge-tag map with per-tag fallbacks, conditional-block rules with per-segment variations, a fallback-safety audit, and a PII guard on what may render, informing the SEND E (Engagement/personalization) dimension. Not for building the segments — use list-segment-builder; not for writing the base copy — use email-creative-builder; not for scoring EQS or running vetoes — use email-quality-auditor. 邮件个性化/合并标签/条件内容块/兜底默认值
Amplify personality — raises layout variance and motion, strengthens typography and one signature detail, without slop. Use when the UI works but feels safe, flat, or "template-y", or when the user says "bolder", "more personality", "more creative", or "make it pop" (still professional). Invoke when the user asks for bolder on their UI, or mentions 'bolder' alongside design / UI / frontend work.
Tone down visual noise — lowers variance and motion, simplifies layout and color weight, keeps hierarchy clear. Use when the UI feels loud, busy, or over-designed, or when the user says "quieter", "more restrained", "simpler", or "tone it down". Invoke when the user asks for quieter on their UI, or mentions 'quieter' alongside design / UI / frontend work.
