Build and debug Enable Banking API integrations for account information (AIS), payment initiation (PIS), ASPSP discovery, user sessions, JWT authentication with RSA certificates, sandbox setup, and TypeScript/Node clients. Use when Codex needs to implement Enable Banking request flows, generate or validate bearer JWTs, model Enable Banking schemas, handle PSU redirect callbacks, fetch accounts/balances/transactions, create payments, or troubleshoot Enable Banking API errors.
Scaffold and architect custom Frappe apps including app structure, hooks, background jobs, service layers, and production hardening. Use when creating new apps, setting up app architecture, or implementing cross-cutting patterns like caching, logging, and error handling.
Reviews, audits, and modifies CockroachDB cluster settings. Self-Hosted has full control over all settings and start flags. Advanced/BYOC can modify most SQL-level settings but infrastructure settings are managed by CRL. Standard has limited settings access — session variables are the primary tuning mechanism. Basic has minimal settings — use session variables and Cloud Console. Use when auditing configuration, tuning performance, or troubleshooting settings-related issues.
Estimates storage requirements for CockroachDB online schema change backfills using SHOW RANGES WITH DETAILS, KEYS, INDEXES. Use before CREATE INDEX, ADD COLUMN with INDEX/UNIQUE, ALTER PRIMARY KEY, CREATE MATERIALIZED VIEW, CREATE TABLE AS, REFRESH, or SET LOCALITY on tables with large per-index footprints, to avoid mid-backfill disk exhaustion.

Low-level Go terminal primitives - cell-based rendering, input handling, screen management. Use when building custom Go terminal renderers, ultraviolet, cell buffers, or performance-critical TUI work below Bubble Tea's abstraction level.
Reviews Forge apps for security vulnerabilities, architecture issues, cost inefficiencies, performance problems, and trigger/scheduling waste before deployment. Use when the user says "review my Forge app", "check my app", "pre-deploy check", "is my app ready to deploy", "audit my Forge app", "check for security issues", "check performance", "review manifest", "check my Forge app for problems", "app review", "optimize my Forge app costs", "reduce invocations", "why is my app expensive", "check my triggers", or any request to evaluate a Forge app's quality, safety, cost efficiency, or readiness. Also triggers when users ask about Forge best practices, permission scopes, resolver optimization, storage efficiency, cold start reduction, frontend offloading, trigger filtering, scheduled trigger frequency, N+1 API calls, bulk API usage, verbose logging, or Forge platform pricing.
Analyze a Materialize environment for health, performance, and optimization opportunities using the MCP Developer endpoint. Use this skill when someone wants to check environment health, investigate performance issues, troubleshoot stale materialized views, diagnose memory pressure, audit resource utilization, or get optimization recommendations. Trigger this even if the user just says "check my environment", "why is my MV stale", "why is my cluster slow", or "what can I optimize".
