Registering or resolving services with MS DI. Keyed services, scopes, decoration, hosted services.
Use when building or maintaining real-time collaborative apps with the DeepSpace SDK on Cloudflare Workers — scaffolding new apps, adding features, debugging a `worker.ts` that imports from `deepspace` / `deepspace/worker` or uses `RecordRoom`, `__DO_MANIFEST__`, or `npx deepspace`. Also use when the user mentions DeepSpace or app.space, or asks for anything involving real-time sync, multiplayer state, live cursors / presence, whiteboards or canvases, collaborative text editing (Yjs), channel-based chat, per-role permissions (RBAC), Durable Object rooms, Stripe-backed subscriptions / paywalls / one-time products / tips / refunds, or one-package deploy to `.app.space` — even if they don't name DeepSpace explicitly.
Personal C# conventions - style/structure (file layout, naming, member/ctor ordering, methods, types, visibility, modern C# 11/12/13 syntax, forbidden patterns, XML doc) and runtime behavior (DateTime/IClock, async, dispose, exceptions + Result, structured logging, secrets/config, LINQ, System.Text.Json, decoupling + DI lifetimes). Load before creating or editing any `.cs` file - writing, reviewing, or refactoring C#; do not lean on recalled conventions.
Explain ABAP objects with full dependency context (via SAPContext) and optional ATC code quality analysis — replicates SAP Joule's "Explain Code" capability, including behavior definitions (BDEF — CRUD graph, determinations/validations, bound handler class). Use when asked to "explain this ABAP", "what does ZCL_X do", "walk me through this class/CDS view/behavior definition", or "review this object's quality".
Install Syndicate Links conversion attribution using the shipped merchant API. Covers Shopify backends, generic checkouts, SaaS apps, webhook workers, and agent surfaces without relying on draft-only SDKs or CDN scripts.
Salesforce Metadata API reference for creating, understanding, or modifying metadata XML files (.object-meta.xml, .flow-meta.xml, etc.) and any of 604 metadata types (CustomObject, Flow, ApexClass, ApexTrigger, Profile, PermissionSet, Layout, ValidationRule, RecordType, EmailTemplate, ...). Use for questions about a type's fields or XML format, or Salesforce DX project structure (force-app/main/default). TRIGGER when: authoring or editing any *-meta.xml file, asking what fields/format a metadata type has, or whenever 'Salesforce metadata' or 'sfdx project' is mentioned. DO NOT TRIGGER when: SOQL/DML/runtime sObject access (use the Enterprise API skill), Tooling API developer records (ApexExecutionOverlayAction, TraceFlag), or non-XML logic (Apex code, LWC JS, Visualforce controllers).
Assists in provisioning instances/tables, designing performant schemas, and querying data in Bigtable. Use when designing Bigtable row keys, configuring column families, writing SQL queries or client library code (Java, Go, Python) for Bigtable, or diagnosing performance/hotspotting issues. Also use when provisioning Bigtable clusters using gcloud or cbt CLIs. Don't use for generic Cloud SQL administration.

Master Odoo ORM patterns: search, browse, create, write, domain filters, computed fields, and performance-safe query techniques.
Interactive Brokers (IBKR) API integration for portfolio management, account queries, and trade execution across multiple account types (Roth IRA, personal brokerage, business). Use when the user mentions IBKR, Interactive Brokers, IB Gateway, TWS API, Client Portal API, brokerage API, portfolio positions, account balances, placing trades via API, multi-account trading, IRA trading restrictions, or wants to build/debug code that connects to Interactive Brokers. Also triggers on "ib_async", "ib_insync", "ibapi", or any IBKR endpoint reference.
Resilience patterns with Spring Cloud Circuit Breaker and Resilience4j. Covers circuit breaker, retry, rate limiter, bulkhead, and fallback patterns. USE WHEN: user mentions "circuit breaker", "resilience4j", "fallback", "retry pattern", "rate limiter", "bulkhead", "fault tolerance Spring" DO NOT USE FOR: basic HTTP errors - handle in code, Hystrix (deprecated) - use Resilience4j instead
Salesforce Industries Common Core (OmniStudio/Vlocity) Apex callable generation and review with 120-point scoring. TRIGGER when: user creates or reviews System.Callable classes, migrates `VlocityOpenInterface` / `VlocityOpenInterface2`, or builds Industries callable extensions used by OmniStudio, Integration Procedures, or DataRaptors. DO NOT TRIGGER when: generic Apex classes/triggers (use sf-apex), building Integration Procedures (use sf-industry-commoncore-integration-procedure), authoring OmniScripts (use sf-industry-commoncore-omniscript), configuring Data Mappers (use sf-industry-commoncore-datamapper), or analyzing namespace/dependency issues (use sf-industry-commoncore-omnistudio-analyze).
