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 | $0.00057 | $0.01018 |
| Opus 5 | $0.00028 | $0.00509 |
| Sonnet 5 | $0.00011 | $0.00204 |
| Haiku 4.5 | $0.00006 | $0.00102 |
Grade A, and why
examples 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 2d 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.

Examples & Walkthroughs
Official Phoenix Guides (Reference)
For standard implementation patterns, always check official guides first:
| Topic | Guide |
|---|---|
| Contexts | hexdocs.pm/phoenix/contexts |
| Ecto Basics | hexdocs.pm/phoenix/ecto |
| LiveView | hexdocs.pm/phoenix_live_view |
| Authentication | mix phx.gen.auth |
| Channels | hexdocs.pm/phoenix/channels |
| Testing | hexdocs.pm/phoenix/testing |
| Deployment | hexdocs.pm/phoenix/deployment |
Plugin-Specific Patterns
Patterns NOT in official guides (unique to this plugin):
Tidewave Integration Workflow
# Requires connected mcp__tidewave__* tools
# Get exact docs for YOUR dependency versions
mcp__tidewave__get_docs "Ecto.Query"
# Execute code in running app
mcp__tidewave__project_eval "MyApp.Accounts.list_users() |> length()"
# Query database directly
mcp__tidewave__execute_sql_query "SELECT count(*) FROM users"
Multi-Agent Review Workflow
# 1. Plan feature with specialist agents
/phx:plan Add user avatars with S3 upload
# 2. After implementation, review with multiple perspectives
/phx:review lib/my_app/accounts.ex # Elixir idioms
# Security analyzer runs automatically on auth code
# 3. Before deployment
# Deployment validator checks production readiness
Iron Laws Enforcement
This plugin enforces non-negotiable rules across all agents:
Elixir Idioms:
- NO process without runtime reason
- Messages are copied (keep small)
- Changesets for external data
LiveView:
- NEVER query DB in mount
- ALWAYS use streams for lists
- RE-AUTHORIZE in every handle_event
Oban:
- Jobs MUST be idempotent
- ALWAYS handle {:error, _} returns
- Use unique keys for deduplication
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.
- 2d ago First seen · 139 lines · 57 tokens per session scan A 4a2fa157846f
examples is a skill published in the GitHub repository oliver-kriska/claude-elixir-phoenix (538 stars, last pushed yesterday), licensed MIT. It adds 57 tokens to every session and 1,018 once invoked, about $0.0003 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 2026-09-03.
