A series of utilities for developers.
- Regex Tester
- HTTP Sink. Send a request and see it echo on the UI.
- Generator diff pipeline. See the diff between versions and flags of
generators, such as
phx.gen.auth,phx.new,scenic.new, ornerves.new. - Community-provided tips that post to Twitter for you from @elixirstream
- ... that's it for now :)
This repo doubles as an agent-skill marketplace. The gendiff skill teaches your
agent to upgrade Elixir/Phoenix generators from real, flag-accurate diffs served by
elixirstream.dev (via /gendiff/api) instead of guessing at what changed.
Claude Code — add this repo as a plugin marketplace, then install:
/plugin marketplace add github://zestcreative/elixirstream
/plugin install elixirstream@elixirstream
The skill loads as elixirstream:gendiff.
Codex (SKILL.md is a cross-agent standard) — drop the skill into your Codex
skills directory:
# project-scoped
mkdir -p .codex/skills && cp -rf skills/gendiff .codex/skills/
# or global, from a clone of this repo
mkdir -p ~/.codex/skills && cp -rf skills/gendiff ~/.codex/skills/Codex auto-discovers any directory under those paths that contains a SKILL.md.
You need to install docker and gem for Ruby and docker needs to be running,
otherwise the app will complain when starting up since it can't build the
Dockerfiles needed for diffing. Colima doesn't seem to work, but docker-ce does
seem to work when mounting volumes. podman might work instead of docker but
is the containerd runtime is untested.
You also need silicon installed to
generate code screenshots.
To start your Phoenix server:
- Setup the project with
mix setup - Start Phoenix endpoint with
iex -S mix phx.server
Now you can visit localhost:4000 from your browser.
flyctl deploy
