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 | $0.00042 | $0.01743 |
| Opus 5 | $0.00021 | $0.00872 |
| Sonnet 5 | $0.00008 | $0.00349 |
| Haiku 4.5 | $0.00004 | $0.00174 |
Grade A, and why
phoenix-generator 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 5d 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 — 314 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Phoenix Generator
This skill helps generate Phoenix resources using built-in generators with proper patterns and best practices.
When to Use
- Creating new Phoenix contexts
- Adding schemas to existing contexts
- Generating LiveView CRUD interfaces
- Creating JSON/HTML resources
- Scaffolding authentication
Available Generators
Context and Schema Generation
mix phx.gen.context - Generate a context with schema and migration
mix phx.gen.context Accounts User users name:string email:string:unique age:integer
Generates:
- Context module:
lib/my_app/accounts.ex - Schema:
lib/my_app/accounts/user.ex - Migration:
priv/repo/migrations/*_create_users.exs - Test files
mix phx.gen.schema - Schema and migration only (no context)
mix phx.gen.schema Accounts.User users name:string email:string:unique
LiveView Generators
mix phx.gen.live - Full LiveView CRUD with context
mix phx.gen.live Catalog Product products \
name:string \
description:text \
price:decimal \
sku:string:unique \
in_stock:boolean
Generates:
- Context and schema
- LiveView modules (Index, Show, Form Component)
- Routes
- Tests
mix phx.gen.live.component - Standalone LiveView component
mix phx.gen.live.component Components.Modal
Traditional Web Generators
mix phx.gen.html - HTML resource with controllers
mix phx.gen.html Blog Post posts title:string body:text published:boolean
mix phx.gen.json - JSON API resource
mix phx.gen.json Shop Product products name:string price:decimal
Field Types and Modifiers
Common Field Types

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.

phoenix-generator is a skill published in the GitHub repository mkreyman/bmad-elixir (10 stars, last pushed 10mo ago), licensed MIT. It adds 42 tokens to every session and 1,743 once invoked, about $0.0002 per session on Opus 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 2026-08-31.
