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 | $0.00038 | $0.01412 |
| Opus 5 | $0.00019 | $0.00706 |
| Sonnet 5 | $0.00008 | $0.00282 |
| Haiku 4.5 | $0.00004 | $0.00141 |
Grade A, and why
write-e2e-test 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 3d 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

Write E2E Test
Create Playwright E2E tests for agentconfig.org following project patterns.

Test File Structure
import { test, expect } from '@playwright/test'
test.describe('Feature Name', () => {
test.beforeEach(async ({ page }) => {
await page.goto('/')
})
test('should do something specific', async ({ page }) => {
// Arrange
const element = page.getByRole('button', { name: 'Click me' })
// Act
await element.click()
// Assert
await expect(page.getByText('Success')).toBeVisible()
})
})
Locator Strategy (Priority Order)
Use the most resilient locators, in this order of preference:
1. Role + Name (most resilient)
page.getByRole('button', { name: 'Submit' })
page.getByRole('heading', { name: 'Welcome' })
page.getByRole('navigation')
2. Label/Placeholder (for form elements)
page.getByLabel('Email address')
page.getByPlaceholder('Enter your email')
3. Text content (for static text)
page.getByText('Learn more')
page.getByText(/welcome/i) // regex for flexible matching
4. Test ID (when others don't work)
page.getByTestId('file-tree-node')
5. CSS selectors (last resort)
page.locator('.custom-component')
Common Test Patterns
Navigation
test('should scroll to section when nav link is clicked', async ({ page }) => {
const navLink = page.getByRole('link', { name: 'File Tree' })
const section = page.getByRole('region', { name: 'File Tree' })
await navLink.click()
await expect(section).toBeInViewport()
})
Theme Toggle
test('should toggle between light and dark mode', async ({ page }) => {
const toggle = page.getByRole('button', { name: /theme/i })
await expect(page.locator('html')).toHaveAttribute('data-theme', 'light')
await toggle.click()
await expect(page.locator('html')).toHaveAttribute('data-theme', 'dark')
})
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.
- 3d ago First seen · 237 lines · 38 tokens per session scan A 05313f7a21f3
write-e2e-test is a skill published in the GitHub repository agentconfig/agentconfig.org (8 stars, last pushed 6d ago), licensed ISC. It adds 38 tokens to every session and 1,412 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.
