A code-review guide for Elixir and Phoenix projects, using focused checks for tests, security, database code, LiveView, background jobs, and deployment settings.

Use it to review changed files, test code, security rules, background workers, deployment configuration, or a specific plan.

It helps find bugs and risky patterns after implementation, before changes are committed.

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.

Any agent

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00051	$0.02294
Opus 5.5	$0.00020	$0.00918
Sonnet 5.5	$0.00010	$0.00459
Haiku 4.5	$0.00005	$0.00229

Security

Grade A, and why

review 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 26d 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.

The opening of the file, as written. The whole thing — 186 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Review Elixir/Phoenix Code

Review code by spawning parallel specialist agents. Find and explain issues — do NOT create tasks or fix anything.

Usage

/phx:review                          # Auto-detects task ID from branch/commits
/phx:review test                     # Review test files only
/phx:review security                 # Run security audit only
/phx:review oban                     # Review Oban workers only
/phx:review deploy                   # Validate deployment config
/phx:review iron-laws                # Check Iron Law violations only
/phx:review ENA-8931                 # Force Linear issue
/phx:review #42                      # Force GitHub issue
/phx:review .claude/plans/auth/plan.md    # Force plan / spec file
/phx:review --no-requirements        # Skip requirements coverage check
/phx:review --codex                  # Add Codex CLI as cross-model reviewer

Arguments

$ARGUMENTS = Focus area, task ID, or path to plan/spec file.

When no requirements argument is passed, the skill auto-detects a task ID from the branch and recent commits (see ${CLAUDE_SKILL_DIR}/references/requirements-detection.md).

Workflow

Step 1: Identify Changed Files and Prepare Directories

Create output dirs before spawning agents — agents cannot create directories, so their writes would fail.

Determine SLUG via Glob on .claude/plans/*/ (default: "review")
Run mkdir -p ".claude/plans/${SLUG}/reviews" ".claude/plans/${SLUG}/summaries" .claude/reviews
Run git diff --name-only HEAD~5 and git diff --name-only main
Save the diff base for pre-existing detection in Step 3b

Step 1b: Load Plan Context and Prior Reviews

Read .claude/plans/${SLUG}/scratchpad.md for planning decisions and rationale
Pass relevant decisions to agents as WHY-context (eliminates session archaeology)
Check .claude/plans/${SLUG}/reviews/ for prior output; if present, include a consolidated summary as "PRIOR FINDINGS" with: "Focus on NEW issues. Mark still-present issues as PERSISTENT."

Files

What ships with it

6 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.

review is a skill published in the GitHub repository oliver-kriska/claude-elixir-phoenix (570 stars, last pushed 3d ago), licensed MIT. It adds 51 tokens to every session and 2,294 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
