Expertise in the Create Simulated Project — a NeoForge Minecraft mod suite adding physics-based contraptions including planes, airships, cars, and land vehicles built on the Create mod framework.
Authoritative reference for Odoo 19 syntax conventions across Python ORM, XML views, OWL/JavaScript, controllers, manifests, and SCSS. Use this skill BEFORE writing or modifying any Odoo code, whenever the user mentions Odoo, an Odoo module, an Odoo model, an XML view, an OWL component, or any file under an Odoo addons directory. Odoo 19 introduces breaking changes (130 model renames, res.groups privilege refactor, hr.contract→hr.version, models.Constraint, attrs removal continued, type='jsonrpc') that older training data does NOT reflect. Always consult this skill before generating code, even if the request looks routine — a model that "obviously" works in Odoo 18 may be wrong in Odoo 19. Trigger this skill on phrases like "create an Odoo module", "add a field to res.partner", "write a controller", "make an OWL component", "fix this Odoo view", "_sql_constraints", "tree view", or any time you see a `__manifest__.py`, `models/*.py`, `views/*.xml`, or `static/src/**/*.js` file in an Odoo project.
This skill should be used when the user asks to "add a background job", "process async", "schedule a task", "retry failed jobs", "add email sending", "run this later", "add a cron job", "unique jobs", "batch process", or mentions Oban, Oban Pro, workflows, job queues, cascades, grafting, recorded values, job args, or troubleshooting job failures.
Use when designing or architecting Elixir/Phoenix applications, creating comprehensive project documentation, planning OTP supervision trees, defining domain models with Ash Framework, structuring multi-app projects with path-based dependencies, or preparing handoff documentation for Director/Implementor AI collaboration
Use when building Elixir applications that need to evaluate JavaScript or TypeScript code, load ES modules, import npm/jsr packages, call JS functions from Elixir, or use V8 snapshots. Triggers on Denox, deno_core, Rustler NIF JS runtime, TypeScript transpilation in Elixir.
This skill should be used when the user works on any .ex or .exs file, mentions Elixir/Phoenix/Ecto/OTP, the project has a mix.exs, or asks "which skill should I use", "new to Elixir", "help with Elixir". Routes to the correct thinking skill BEFORE exploring code. Triggers on "implement", "add", "fix", "refactor" in Elixir projects.
This skill should be used when the user asks to "add a database table", "create a new context", "query the database", "add a field to a schema", "validate form input", "fix N+1 queries", "preload this association", "separate these concerns", or mentions Repo, changesets, migrations, Ecto.Multi, has_many, belongs_to, transactions, query composition, or how contexts should talk to each other.
Monitors CockroachDB background job health by identifying failed, paused, and long-running jobs using SHOW JOBS and SHOW AUTOMATIC JOBS. Surfaces schema changes, backups/restores, automatic statistics collection, and SQL stats compaction jobs without DB Console access. Use when investigating schema change delays, failed backups, or automatic job issues.
Validate pending migrations for foreign key consistency, rollback safety, and best practices
Create and manage a DDD bounded context with standard directory structure
Expert logging guidance based on Boris Tane's loggingsucks.com philosophy. Use when implementing logging, adding observability, debugging production issues, or reviewing code that includes log statements. Covers wide events architecture, structured logging, smart sampling, and high-cardinality field design.
Guidelines for fixing Motoko compiler warnings (moc). Use when asked to fix, suppress, or clean up Motoko compiler warnings from `dfx build --check`.
