elixir-skills

Adds Credo, Dialyxir, Dialyzer PLT layout, and mix lint / mix lint:quick aliases to an existing Elixir project. Use when bootstrapping CI lint, typecheck, or reproducing the diode-drive mix lint workflow in another repo.

Creates or extends bash `run` scripts with `run rpc <expression>` and `scripts/rpc` for remote Elixir/Erlang RPC on running nodes. Detects iex/mix dev vs release (`bin/app rpc`) patterns. Use when adding run/rpc/remsh scripts, remote RPC over SSH, or unifying split run+remsh scripts.

Use when the user asks to review a branch, review code changes, code review a PR, check branch quality, or evaluate changes against project guidelines.

Installs the GitHub cursor issue workflow (workflow.exs and README) into `.cursor/issue-workflow/`, installs the `branch-code-review` project skill into `.cursor/skills/`, runs `workflow.exs --create-labels` once for GitHub labels, then prompts about workflow tweaks. Use when bootstrapping issue/PR automation, setting up cursor labels, copying the issue workflow into a repo, or installing branch review plus label workflow.

Configure rotated and compressed file logging for Elixir/Phoenix projects using :logger_std_h. Use when setting up production logging, configuring logger rotation, or when the user asks to add file logging to an Elixir project.

Debug and investigate concrete issues on a running Elixir/Erlang node using live RPC (run rpc, remsh rpc, scripts/rpc, or bin/app rpc). Forms hypotheses from user symptoms, runs read-only checks, interprets output. Use when debugging production/staging/dev node behavior, inspecting process state, or investigating user-reported live system issues.

Review branch changes against AGENTS.md guidelines. Fetch intended goal from PR/issue, check correctness (logic, goal alignment, conciseness), focus on new changes only, pull GitHub PR comments if available via gh CLI. Output summary, alignment score (1-10), and LLM prompts to fix issues. Propose posting the review as a PR comment when one exists. Use when the user asks to review a branch, code review a PR, or review changes.

Autonomous Goal-directed Iteration. Apply Karpathy's autoresearch principles to ANY task. Loops autonomously — modify, verify, keep/discard, repeat forever until stopped.

Guides users through creating implementation specifications for libraries, features, and API changes. Use when the user wants to write a spec document, define a new feature for an existing product, create a multi-language library spec, or formalize API/behavior changes in the whenwords/SPEC.md style.

Detects and removes cyclic compile-time dependencies in Elixir codebases using mix xref, with minimal code changes. Use when the user explicitly asks to check for cycles, remove cyclic dependencies, or fix xref cycle failures. Requires Elixir 1.19 or higher for accurate results.
