What its author says it does

Copied from the file, not written here

Detailed coding patterns for a polyglot stack. TRIGGER when: working in Elixir, TypeScript, Go, Rust, Python, Lua, C, Zig, Shell/Bash, Noir, or chezmoi templates. Provides incorrect/correct examples that complement CLAUDE.md preferences. DO NOT TRIGGER when: working with Claude API or Anthropic SDK (use claude-api skill), Raxol TUI/agent framework patterns (use raxol skill), Solidity smart contracts (use solidity-auditor skill), ZK circuit domain questions (use noir skill -- this skill only covers Noir language syntax), NIF/SIMD domain questions for BEAM integration (use native-code skill -- this skill only covers C and Zig general syntax), or ffmpeg upstream / libav* assembly work (use ffmpeg-asm skill).

droo-stack

Concrete coding patterns for a polyglot stack. Each rule shows Incorrect and Correct examples with rationale. These complement CLAUDE.md (which sets high-level preferences) with detailed, actionable reference material.

What You Get

Incorrect/Correct code examples with rationale for each language
Patterns organized by impact level (critical, high, medium)
Language-specific idioms: pipes, pattern matching, error handling, testing
Complements CLAUDE.md preferences with concrete, actionable rules

When to use

This skill activates contextually when working in the languages below. Read the relevant rule file for the language you're working in.

Rules by impact

CRITICAL

go-errors -- Error wrapping, errors.Is/errors.As, sentinel errors
rust-errors -- thiserror/anyhow, ? operator, From implementations
noir-patterns -- Field vs integers, constrained/unconstrained, nargo tests

HIGH

elixir-patterns -- with chains, pipes, pattern matching in function heads
typescript-zod -- Zod schemas, discriminated unions, safeParse
typescript-patterns -- Functional patterns, strict mode, error handling
go-testing -- Table-driven tests, t.Run, t.Helper()
rust-patterns -- Builder pattern, derive traits, clippy, iterators
c-patterns -- Memory ownership, const correctness, error codes, string safety
zig-patterns -- Error unions, comptime generics, allocators, C interop, build.zig
python-cli -- Typer scaffolding, pydantic models, pathlib, pytest
lua-modules -- Module pattern, metatables, LuaLS annotations
shell-patterns -- Traps, getopts, [[ ]], quoting, set -euo pipefail

MEDIUM

elixir-testing -- ExUnit patterns, real dependencies over mocks
python-patterns -- Type hints, f-strings, async, comprehensions
chezmoi-templates -- Whitespace trimming, conditionals, run_onchange scripts
