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.

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 | $0.00018 | $0.01926 |
| Opus 5.5 | $0.00007 | $0.00770 |
| Sonnet 5.5 | $0.00004 | $0.00385 |
| Haiku 4.5 | $0.00002 | $0.00193 |
Grade A, and why
elixir-phoenix-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 2mo 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.
How it starts
The opening of the file, as written. The whole thing — 169 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
`elixir-phoenix-review` # Review all changed files
`elixir-phoenix-review` test # Review test files only
`elixir-phoenix-review` security # Run security audit only
`elixir-phoenix-review` oban # Review Oban workers only
`elixir-phoenix-review` deploy # Validate deployment config
`elixir-phoenix-review` iron-laws # Check Iron Law violations only
`elixir-phoenix-review` .codex/plans/auth/plan.md # Review implementation of plan
Arguments
$ARGUMENTS = Focus area or path to plan file.
Workflow
Step 1: Identify Changed Files and Prepare Directories
CRITICAL: Create output dirs BEFORE spawning agents — agents cannot create directories and will fail repeatedly on writes.
Determine SLUG from the most recent plan directory (use rg --files on .codex/plans/*/), default to "review".
Run mkdir -p ".codex/plans/${SLUG}/reviews" ".codex/plans/${SLUG}/summaries" and mkdir -p .codex/reviews.
Then run git diff --name-only HEAD~5 and git diff --name-only main to identify changed files. Save the diff base for pre-existing detection in Step 3b.
Step 1b: Load Plan Context (Scratchpad)
If reviewing a plan, read .codex/plans/${SLUG}/scratchpad.md for
planning decisions, rationale, and handoff notes. Include relevant
decisions in each agent's prompt so they have context about WHY
code was written a certain way. This eliminates session archaeology.
Step 1c: Check Prior Reviews
If .codex/plans/${SLUG}/reviews/ has prior output, include consolidated
summary in each agent's prompt as "PRIOR FINDINGS" with instruction:
"Focus on NEW issues. Mark still-present issues as PERSISTENT."
Step 2: Create Task List and Spawn Review Agents (MANDATORY)
NEVER spawn the same agent role twice in one review. If reviewing a plan, scope ALL agents to the plan's changed files in a single pass. Do NOT run a scoped review followed by a broader review — one pass per role.
What ships with it
5 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.
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.

elixir-phoenix-review is a skill published in the GitHub repository ccarvalho-eng/codex-elixir-phoenix (11 stars, last pushed 5mo ago), licensed MIT. It adds 18 tokens to every session and 1,926 once invoked, about $0.0001 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 2026-08-30.
