elixir-phoenix

A development add-on for Elixir applications using Phoenix, a web framework, and LiveView, which builds interactive web pages with Elixir. It includes specialist agents, development rules, and Tidewave MCP integration.

In plain words
What is it for?
Use it when building or maintaining Elixir, Phoenix, LiveView, Ecto database, Oban background-job, or OTP applications.
Why use it?
It provides tools and guidance tailored to this specific Elixir web-development stack. Without it, a general coding agent may lack the project's specialised conventions and integrations.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Grade A, and why

elixir-phoenix scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it installs

The manifest is a name and a version. 7 skills, 26 agents, 10 hooks travel with it, and installing the plugin installs all of them — 1,286 tokens a session between them. Each is measured on its own page, and each can be installed alone.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
