What it does
Phx Init is an agent skill from oliver-kriska/claude-elixir-phoenix. Initialize plugin in a project — install Iron Laws, auto-activation; Use when setting up or updating the plugin.
Its SKILL.md is about 1.4k tokens, which your agent loads only when the skill is triggered. The skill folder holds 3 other files, including reference files (for example `references/codex-review-guidelines.md` and `references/injectable-template.md`).
It sits in Agent Workflows. It works with Elixir. The repository describes itself as: Claude Code plugin for Elixir/Phoenix/LiveView — 26 specialist agents, Iron Laws enforcement, and Tidewave MCP integration. Plan features with parallel research agents, execute… The licence is MIT.
When your agent uses it
- Updating the plugin
Example prompts
- “/phx-init”
Workflow steps
5 steps, taken from the step headings in SKILL.md.
What it can do on your machine
Read from SKILL.md and the folder at commit 9767a82. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
codex
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Phx Init loads about 1.4k tokens when it runs, and up to ~4k if it reads all its reference files. Until then it costs about 30 tokens; SKILL.md has 523 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

- description
- Initialize plugin in a project — install Iron Laws, auto-activation; Use when setting up or updating the plugin.
Plugin Initialization
Install the Elixir/Phoenix plugin's behavioral instructions into the project's CLAUDE.md.
Usage
$elixir-phoenix:phx-init # First-time installation
$elixir-phoenix:phx-init --update # Update existing installation with latest rulesIron Laws
- NEVER overwrite content outside plugin markers — User-written CLAUDE.md rules must be preserved verbatim
- Always detect stack before generating — Never assume Phoenix/Ecto versions
- Always validate after installation — Verify markers present and stack correct
Workflow
Step 1: Check Existing CLAUDE.md
Use Glob to check if CLAUDE.md exists. Then use Grep to check for existing ELIXIR-PHOENIX-PLUGIN:START marker in CLAUDE.md.
Step 2: Detect Project Stack
Scan the project to customize the injected instructions:
Read mix.exs and use Grep to extract:
- Phoenix version: search for
phoenix.*"~>inmix.exs - Ecto version: search for
ecto.*"~>inmix.exs - Oban: search for
"oban"and"oban_pro"inmix.exs - Frameworks: search for
"ash","surface"inmix.exs - Tidewave: search for
"tidewave"inmix.exs - Project size: use Glob to count
lib/**/*.exfiles
Step 3: Handle Installation Modes
Mode A: Fresh Install (no CLAUDE.md or no markers)
- Create/append to CLAUDE.md
- Insert full behavioral instructions between markers
- Include only relevant sections based on detected stack
Mode B: Update (--update flag or markers exist)
- Find content between
<!-- ELIXIR-PHOENIX-PLUGIN:START -->and<!-- ELIXIR-PHOENIX-PLUGIN:END --> - Replace with latest behavioral instructions
- Preserve everything outside the markers
In both modes, CLAUDE.md content outside the plugin markers — user-written rules, project conventions, other plugin sections — stays verbatim (Iron Law 1)
Step 4: Generate Content
Write the following structure to CLAUDE.md:
<!-- ELIXIR-PHOENIX-PLUGIN:START -->
<!-- Last updated: {date} | Plugin version: 1.0 | Stack: Phoenix {version}, Ecto {version}, {optional: Oban, Tidewave} -->
# Elixir/Phoenix Plugin - Auto-Activation Rules
{Include all sections from the Content Template below, filtered by detected stack}
<!-- ELIXIR-PHOENIX-PLUGIN:END -->Step 4b: Offer Codex Review Guidelines (optional)
If command -v codex succeeds (or the user asks): offer to install a
managed ## Review guidelines block into the project's AGENTS.md —
honored by BOTH codex exec review locally and the Codex cloud PR
reviewer. Follow the install rules and exact block in
references/codex-review-guidelines.md: markers
ELIXIR-PHOENIX-REVIEW-GUIDELINES:START/END, upsert in place on
--update, never touch content outside markers, and STOP to ask if an
unmanaged ## Review guidelines section already exists. When codex is
absent and not requested, skip silently — never mention codex to users
who don't have it.
Show full SKILL.md (204 more words)Show less
Step 5: Output Summary
✅ Elixir/Phoenix plugin initialized
Detected stack:
- Phoenix {version}
- Ecto {version}
- {Oban standard | Oban Pro | not detected}
- {Tidewave ✓ | Tidewave not detected}
- {Ash Framework detected - Ecto patterns disabled | not detected}
Added to CLAUDE.md:
- Auto-activation rules (complexity detection, interview mode)
- Agent trigger patterns ({n} agents available)
- Reference auto-loading ({n} reference docs)
- Iron Laws enforcement ({n} laws)
- Verification rules
{- Codex review guidelines → AGENTS.md (only if installed in Step 4b)}
Run $elixir-phoenix:phx-init --update after plugin updates.
Run $elixir-phoenix:phx-audit for a full project health check.Content Template
The exact content to inject is in references/injectable-template.md.
Key structure:
- Routing table — which
$elixir-phoenix:phx-*command fits which kind of request - Iron Laws — STOP behavior on violations
- Conditional Sections — Include based on detected stack:
{OBAN_SECTION}— If Oban detected (not Pro){OBAN_PRO_SECTION}— If Oban Pro detected{ASH_SECTION}— If Ash Framework detected{TIDEWAVE_SECTION}— If Tidewave detected
- Verification — Mandatory after code changes
- Quick Reference — Skill routing table
Placeholder substitution:
| Placeholder | Source |
|---|---|
{DATE} | Current date |
{PHOENIX_VERSION} | From mix.exs |
{ECTO_VERSION} | From mix.exs |
{OPTIONAL_STACK} | Detected optional deps |
See references/injectable-template.md for full template with all placeholders and conditional sections.
Validation
After running $elixir-phoenix:phx-init:
- Check CLAUDE.md contains markers
- Verify detected stack matches actual project
- New session should:
- Auto-detect complexity when given tasks
- Stop on Iron Law violations
- Offer relevant workflows based on task
Error Handling
| Scenario | Action |
|---|---|
| CLAUDE.md read-only | Error: "Cannot modify CLAUDE.md - check permissions" |
| Markers corrupted | Warn, offer to remove and reinstall |
| Unknown Phoenix version | Use conservative defaults (all features enabled) |
| Not an Elixir project | Error: "No mix.exs found - is this an Elixir project?" |
Relationship to Other Commands
| Command | When to Use |
|---|---|
$elixir-phoenix:phx-init | First time, or after plugin updates |
$elixir-phoenix:phx-audit | Periodic project health check |
$elixir-phoenix:phx-verify | After code changes |
