基于 SOC 职业分类
Scaffold East / e3 projects with the `npm create @elaraai/e3` and `npm create @elaraai/east` initializers. Use when: (1) Creating a new project from scratch ('create an e3 project', 'set up an East project', 'new project called X'), (2) Choosing e3 (durable dataflow, Node+Python+C) vs east (Node-only), (3) Deciding CLI flags — --runners, --platform, --python-packages / --node-packages / --c-packages, --ui, --tests, --eslint, --install — and understanding exactly what each generates, (4) Splitting platform code into per-runtime workspace packages for per-package change detection. After scaffolding, the east-project skill drives the build/deploy/run/watch lifecycle.
East Execution Engine (e3) - durable dataflow execution for East programs. Use when: (1) Authoring e3 packages with @elaraai/e3 (e3.input, e3.task, e3.customTask, e3.function, e3.ui, e3.package, e3.export), (2) Running e3 CLI commands (e3 repo, e3 workspace, e3 package, e3 dataset, e3 task, e3 dataflow run, e3 call, e3 watch, e3 auth), (3) Working with workspaces and packages, (4) Content-addressable caching and reactive dataflow execution.
I/O platform functions for the East language on Node.js. Use when writing East programs that need SQL databases (SQLite, PostgreSQL, MySQL), NoSQL databases (Redis, MongoDB), S3 storage, file transfers (FTP, SFTP), file format parsing (XLSX, XML), or compression (Gzip, Zip, Tar). Triggers for: (1) Writing East programs with @elaraai/east-node-io, (2) Database operations with SQL.SQLite, SQL.Postgres, SQL.MySQL, NoSQL.Redis, NoSQL.MongoDB, (3) Cloud storage with Storage.S3, (4) File transfers with Transfer.FTP, Transfer.SFTP, (5) Format parsing with Format.XLSX, Format.XML, (6) Compression with Compression.Gzip, Compression.Zip, Compression.Tar.
Node.js platform functions for the East language. Use when writing East programs that need Console I/O, Environment variables, FileSystem operations, HTTP Fetch requests, Cryptography, Time operations, Path manipulation, Random number generation, or Testing. Triggers for: (1) Writing East programs with @elaraai/east-node-std, (2) Using platform functions like Console.log, Env.get, FileSystem.readFile, Fetch.get, Crypto.uuid, Time.now, Path.join, Random.normal, (3) Testing East code with describeEast and Assert, (4) Passing credentials/secrets to East tasks without putting them in source.
Data science and machine learning platform functions for the East language (TypeScript types + directly-callable Python implementations). Use when writing East programs that need optimization (MADS, Optuna, SimAnneal, Scipy, Optimization, GoogleOr), machine learning (XGBoost, LightGBM, NGBoost, Torch MLP, Lightning, GP), Bayesian inference (PyMC), causal inference (Causal: DoWhy, EconML DML, ALE), simulation (Simulation DES), ML utilities (Sklearn preprocessing, metrics, splits), conformal prediction (MAPIE), or model explainability (SHAP). Triggers for: (1) Writing East programs with @elaraai/east-py-datascience, (2) Derivative-free optimization with MADS, (3) Bayesian optimization with Optuna, (4) Discrete/combinatorial optimization with SimAnneal, (5) Gradient boosting with XGBoost or LightGBM, (6) Probabilistic predictions with NGBoost or GP, (7) Neural networks with Torch MLP or Lightning, (8) Data preprocessing and metrics with Sklearn, (9) Conformal prediction intervals with MAPIE, (10) Model explainab
I/O platform functions for the East language on the Python runtime - SQL databases (SQLite, PostgreSQL, MySQL, Access), NoSQL (Redis, MongoDB), S3 storage, file transfers (FTP, SFTP), file formats (XLSX, XML), and compression (Gzip, Zip, Tar). Use when writing Python (not the TypeScript DSL) that calls or registers these platform functions. Triggers for: (1) Calling east_py_io *_impl functions directly from a project's own Python @platform_function (sqlite_query_impl, mongo_find_impl, s3_put_object_impl, ftp_get_impl, xlsx_read_impl, gzip_compress_impl, ...), (2) Registering the east_py_io platform list with compile() so East programs can use SQL/NoSQL/Storage/Transfer/Format/Compression on the Python runtime, (3) Building connection configs (SqliteConfigType, PostgresConfigType, RedisConfigType, S3ConfigType, FtpConfigType, ...) in Python, (4) The connect -> handle -> operate -> close connection lifecycle. For authoring East programs in TypeScript against these functions, use the east-node-io skill instead.

Read the README.md file within this skill, and explore the other available files.
Non-negotiable for any East component or screen: pass every line of guidelines/component-rules.md (semantic tokens only — no raw hex; every numeral JetBrains Mono tabular; status = dot + uppercase mono word, never a tinted badge; structure from 1px rules, shadows only on overlays; dashed = ephemeral; must work with data-theme="dark" unchanged). Compose from the 8 core atoms in components/core/ (Button, Chip, Status, DeltaPill, Tag, Kbd, Banner, Avatar); build larger patterns fresh, copying anatomy and exact dimensions from guidelines/reference/ (spec.css is the source of truth).
If creating visual artifacts (slides, mocks, throwaway prototypes, etc), copy assets out and create static HTML files for the user to view. If working on production code, you can copy assets and read the rules here to become an expert in designing with this brand.
If the user invokes this skill without any other guidance, ask them what they want to build or design, ask some questions, and act as an expert designer who outputs HTML artifacts or production code, depending on the need.
