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 | $0.00034 | $0.00788 |
| Opus 5 | $0.00017 | $0.00394 |
| Sonnet 5 | $0.00007 | $0.00158 |
| Haiku 4.5 | $0.00003 | $0.00079 |
Grade A, and why
phx-quick 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 4d 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.
This is a copy
92% identical to quick — 18 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 156 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Quick Mode
Skip the planning ceremony. Get working code fast.
Usage
phx-quick Add pagination to posts
phx-quick Fix the login redirect bug
phx-quick Add CSV export to reports
Arguments
$ARGUMENTS = What to implement
How It Differs
| Normal Mode | Quick Mode |
|---|---|
| Spawn research agents | No agents |
| Create plan document | Mental model only |
| Parallel review | Optional single review |
| Multiple iterations | Single pass |
Workflow
- Understand - Read relevant files (max 3)
- Implement - Write code directly
- Verify - Quick compile check
- Done - No ceremony
Iron Laws
- NEVER skip verification — run
mix compile --warnings-as-errorsafter every change, even in quick mode - DO NOT touch files outside the stated scope — quick mode means minimal blast radius; if a fix requires changes across multiple domains, escalate to
phx-plan - NEVER bypass security checks for speed — auth, input validation, and XSS rules apply regardless of change size
Rules in Quick Mode
Still Enforced (Iron Laws)
- ✓ No process without runtime reason
- ✓ No DB in mount
- ✓ Security basics (no SQL injection, etc.)
- ✓ Run
mix format
Skipped
- ✗ Parallel agent research
- ✗ Written plan document
- ✗ Multiple review passes
- ✗ Documentation updates
When to Use
Good for:
- Bug fixes with clear solution
- Small features (<100 lines)
- Refactoring with tests
- Adding fields/columns
- UI tweaks
Not for:
- New authentication flows
- Payment integration
- Data migrations
- Architectural changes
- Anything touching security
Quick Patterns
Add Field
/quick Add phone field to users
→ Migration + schema + changeset + form field
Fix Bug
/quick Fix: posts not showing for admin users
→ Find issue + fix + verify
Add Endpoint
/quick Add GET /api/health endpoint
→ Route + controller + response
Escape Hatch

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.

phx-quick is a skill published in the GitHub repository oliver-kriska/claude-elixir-phoenix (539 stars, last pushed 2d ago), licensed MIT. It adds 34 tokens to every session and 788 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. It is 92% identical to quick, differing in 18 lines, and is treated as a copy.
