Apply Moodle coding standards (PSR-12 with exceptions) to PHP code. Validates style, naming conventions, PHPDoc, and type hints.
Review WooCommerce code changes for coding standards compliance. Use when reviewing code locally, performing automated PR reviews, or checking code quality.
Write clean, readable, and maintainable code following principles from Robert C. Martin's "Clean Code" and Object Calisthenics. Use when writing, reviewing, or refactoring code to improve naming, function design, formatting, error handling, and class structure. Includes code smell detection and refactoring guidance.
Python coding standards with automatic version detection. Use when writing, reviewing, or refactoring Python to ensure adherence to LBYL exception handling patterns, modern type syntax (list[str], str | None), pathlib operations, ABC-based interfaces, absolute imports, and explicit error boundaries at CLI level. Also provides production-tested code smell patterns from Dagster Labs for API design, parameter complexity, and code organization. Essential for maintaining erk's dignified Python standards.
Generate a project-specific CLAUDE.md (or AGENTS.md) with coding standards, style guides, and best practices. Triggers on any request to set up a project, initialize coding standards, create or update CLAUDE.md or AGENTS.md, configure agent instructions, add code quality rules, or start a new codebase. Use this skill at the start of every new project.
Specifies Poetry or Rye for dependency management in Python projects.
Style rules and idioms for writing high-quality Zener HDL code. Use when writing, reviewing, or refactoring `.zen` files — modules, reference designs, or board files. Covers DNP patterns, typed configs, voltage checks, component naming, computation style, and common gotchas.
Captures executable contracts and coding knowledge into .trellis/spec/ documents after implementation, debugging, or design decisions. Enforces code-spec depth for infra and cross-layer changes with mandatory sections for signatures, contracts, validation matrices, and test points. Use when a feature is implemented, a bug is fixed, a design decision is made, a new pattern is discovered, or cross-layer contracts change.
TypeScript language patterns and type safety rules — strict mode, no any, discriminated unions. Use when writing TypeScript code, reviewing types, or enforcing type safety.
Personal PHP conventions enforced when creating, modifying, or planning code that will touch PHP files. Covers strict types, function imports, testing philosophy, class design, observability, and planning practices. Activate whenever working on PHP code.
Comprehensive Python development skill covering coding standards, CLI development, linting, testing, debugging, refactoring, code review, auditing, documentation, project planning, and bulk operations. Use when writing, reviewing, refactoring, debugging, or documenting Python code; configuring linters; setting up CLI tools; planning features; performing code audits; or handling bulk operations (10+ files) that need 90%+ token savings.
Review changes starting from a fixed point (commit, branch, tag, or merge-base) along two axes: Standards (Does the code comply with the coding standards documented in this repository?) and Spec (Does the code meet the requirements from the source issue/PRD?). The two reviews run in parallel sub-agents and report side by side. This applies when users want to review a branch, PR, in-progress changes, or request a "review since X".
