Data & Analytics

woocommerce Skill

Use when the merchant asks which products are performing best, what changed in product mix, which products entered or dropped out of top sellers, which categories or SKUs are carrying sales, which products did not move, or which product refund signals deserve attention. Produces a merchant-friendly WooCommerce product trading review using existing analytics tools, with aggregated data only, no customer PII, no forecasts, and no suggestions to build new tools.

woocommerce Skill

Use when the merchant asks how customer acquisition is performing, whether new customers are growing, which channels brought first-time customers, how new customers compare with returning customers, or what practical acquisition actions to take. Produces a merchant-friendly WooCommerce customer acquisition review using existing analytics tools, with aggregated data only, no customer PII, no forecasts, and no suggestions to build new tools.

woocommerce Skill

Use when the merchant asks which countries are driving revenue, orders, customers, refunds, or geographic mix changes; whether revenue is concentrated by country; which country-level signals need operational attention; or whether tax-threshold context is relevant. Produces a merchant-friendly WooCommerce billing-country performance review using existing analytics tools, with aggregated data only, no customer PII, no legal or tax advice, and no suggestions to build new tools.

woocommerce Skill

Use when the merchant asks how to merchandise the catalogue, which products or categories deserve attention, which products are slow movers, how current stock or sale pricing affects product placement, or which product pages need practical improvements. Produces a merchant-friendly WooCommerce catalogue merchandising review using existing analytics and product tools, with aggregated data only, no customer PII, no forecasts, and no suggestions to build new tools.

txyzznc Bundle

COG项目配置表设计与生成工具。专注于配置表的设计规范和TXT格式生成。强制规范：配置表中使用资源ID（int类型）而非资源路径。使用DataTableGenerator的DataTable创建方式，确保与游戏框架兼容。TXT转XLSX格式转换由用户手动执行。

imbue-ai Skill

Show a file to the user in chat. Display an image inline (chart, plot, screenshot, diagram, rendered figure, photo), or offer any other file (PDF, CSV, log, zip, spreadsheet, ...) as a download link. Use whenever you have a file on disk you want the user to see or download, or want to embed an image from a public URL.

unknown-333 Skill

Protect personally identifiable information in data pipelines — classifying PII, choosing masking vs tokenization vs hashing vs encryption, dynamic data masking and column-level access control, and handling deletion/right-to-be-forgotten. Use when handling sensitive data, masking or anonymizing PII, meeting GDPR/CCPA/HIPAA requirements, or restricting column access in a warehouse.

unknown-333 Bundle

Optimize slow analytical SQL by reading query/EXPLAIN plans, cutting scanned data, fixing join strategy, and using partitioning, clustering, and indexes across Postgres, Snowflake, BigQuery, Databricks/Spark SQL, and Redshift. Use when a query is slow, times out, costs too much, scans too many rows/bytes, or spills to disk.

unknown-333 Skill

Optimize slow or failing PySpark and Spark SQL jobs — partitioning and repartitioning, data skew, shuffles, broadcast joins, caching, Adaptive Query Execution, and avoiding driver collects and Python UDFs. Use when a Spark job is slow, spills, OOMs, has skewed tasks, runs a huge shuffle, or a stage hangs on a few straggler tasks.

unknown-333 Skill

Define and enforce data contracts between producers and consumers — explicit schema, semantics, ownership, SLAs, and versioning — to prevent silent upstream changes from breaking downstream pipelines. Use when a producer schema change could break consumers, defining an interface between teams/services and the warehouse, or adding schema enforcement at ingestion.

unknown-333 Skill

Evolve data schemas safely over time — backward/forward compatibility, additive vs breaking changes, column adds/renames/type changes, and evolution in Avro, Parquet, Iceberg, Delta, and warehouse tables. Use when changing a table or event schema, adding or renaming columns, changing types, or preventing a schema change from breaking readers or pipelines.

unknown-333 Bundle

Design analytics data models using dimensional modeling — star and snowflake schemas, fact and dimension tables, grain declaration, surrogate keys, and slowly changing dimensions (SCD Type 1/2/3). Use when designing a warehouse schema, building marts, choosing a table grain, tracking history, or deciding fact vs dimension.

unknown-333 Skill

Optimize columnar Parquet storage for analytics — file and row-group sizing, compression codecs (Snappy/ZSTD), partitioning and file layout, column pruning and predicate pushdown, dictionary encoding, and fixing the small-files problem. Use when Parquet reads are slow or costly, files are too small/large, choosing compression or partitioning, or improving scan pruning on a data lake.

nativescript Skill

Use when a ListView janks or stutters while scrolling, an itemTemplates template never applies, analytics or side effects in itemLoading fire far too often, or when writing itemLoading handlers / itemTemplateSelector / refresh() — the args.view recycling contract (only create when absent), the selector's silent fallback to the default template on unknown keys, and why refresh() re-fires itemLoading for every item.

paultyng Bundle

Review database usage for migration safety, query performance, connection/transaction management, and schema design. Covers PostgreSQL and MySQL. Runs squawk for PostgreSQL migration linting if available. Use when the user asks for a database review, SQL review, migration review, or schema review.

estuary Skill

Write Estuary derivations in Python — async-generator transforms, Pydantic-typed source/output, optional persistent state, and dependency installation via uv. Use for ML/embeddings, async API calls, or any transform where SQL and TypeScript are awkward. Derivations add complexity and cost (and Python derivations require a private/BYOC data plane) — confirm the user wants a Python derivation before reaching for this. Use when user says "python derivation", "write a derivation in python", "embed with a python derivation", "ML derivation", "call an API from a derivation", or anything mentioning model2vec / huggingface / pydantic in a derivation context.

estuary Skill

Create an Estuary derivation that joins two or more collections on a shared key, merging their fields into a single enriched collection. Use for data enrichment, denormalisation, building wide tables for BI, and real-time CDC joins. Derivations add complexity and cost — confirm the user wants a derivation before reaching for this (a destination-side SQL join or BI tool view is often simpler). Use when user says "join-collections derivation", "derivation to join two collections", "transformation to enrich with customer data", "derive a wide table", "lookup-join derivation", or "build a join derivation".

estuary Skill

Create an Estuary derivation that continuously aggregates metrics (daily totals, running counts, min/max, lifetime revenue) using reduction annotations. Use for real-time dashboards, continuous materialised views, and replacing batch ETL aggregations with streaming. Derivations add complexity and cost — confirm the user wants a derivation before reaching for this. Use when user says "aggregation derivation", "derivation to sum daily totals", "running-count derivation", "transformation for min/max per group", "derive lifetime metrics", "aggregate-by-date derivation", or "real-time-dashboard derivation".

alterlab-ieu Skill

Invoke when the user needs to set up analytics, define telemetry events, establish KPIs, build dashboards, configure A/B testing, or implement data-driven design capabilities. Triggers on: "analytics", "telemetry", "KPIs", "metrics", "player data", "retention", "DAU", "dashboard", "A/B testing", "funnel analysis". Do NOT invoke for balance tuning (use game-balance-check) or economy design (use game-economy-designer). Part of the AlterLab GameForge collection.

gcwing Skill

Pre-landing PR review. Analyzes diff against the base branch for SQL safety, LLM trust boundary violations, conditional side effects, and other structural issues. Use when explicitly asked for the specialized pre-landing workflow. Product `/review` requests are handled by OpenBitFun's unified Review mechanism instead. (gstack)

ilyautov Bundle

Проводит собственника через закрытие месяца: сверяет данные бухгалтерии (1С/МойСклад) с зачислениями эквайринга и выписками банка, помечает операции без статьи, подозрительные дубли и недостающие первичные документы, затем пишет ОПиУ-сводку простым языком и выгружает пакет закрытия месяца (xlsx + PDF на одну страницу). Триггеры: «закрой месяц», «закрытие месяца», «сделай месячную отчётность», «сверка», «что не сходится», «ОПиУ», «финрезультат», а также вопросы «почему изменилась выручка/маржа в этом месяце».

ilyautov Bundle

Берёт дебиторку и кредиторку, историю сроков поступления денег и известные постоянные расходы из бухгалтерии (1С, МойСклад) и платёжных сервисов (ЮKassa, Тинькофф, банк-выписка) — или из выгрузки CSV — и строит прогноз денежного потока на 30/60/90 дней с доверительными коридорами по проценту отклонения и поимёнными флагами рисков. На выходе — сводка в чат и XLSX для скачивания. Триггеры: «посчитай денежный поток», «спрогнозируй кэшфлоу», «хватит ли на зарплату», «на сколько хватит денег», «запас прочности», «кассовый разрыв», «хватит ли на налоги». В выплаты ВКЛЮЧАЕТ предстоящие налоги и взносы (из навыка tax-calendar-proactive) — именно они чаще всего создают кассовый разрыв. Если коннектор не подключён — переходит на выгрузку CSV или грубый режим по средним.

evan-daruwalla Bundle

Read-only source-vs-target assertion after a data transform or copy — prove every row moved. Compares CSV or SQLite endpoints (--src/--dst as csv:<path> | sqlite:<db>:<table>) on row count + an order-independent XOR content checksum; --key <col> names the first 10 missing keys. SQLite opens mode=ro. Use when: "validate the copy", "did every row move", "verify the ETL", "reconcile the table after a rebuild". Python stdlib only.

a-novel-kit Skill

Base Go conventions for EVERY Go repo in the a-novel and a-novel-kit orgs — naming, error handling, dependency policy, context, the format/lint discipline, time, and secrets.
