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 | $0.00082 | $0.01033 |
| Opus 5.5 | $0.00033 | $0.00413 |
| Sonnet 5.5 | $0.00016 | $0.00207 |
| Haiku 4.5 | $0.00008 | $0.00103 |
Grade A, and why
e2e-test-suite-init 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 1mo 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 — 130 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Initialise E2E Test Suite
Scaffold the entire e2e/ directory structure with all configuration files, base classes, fixtures, and helpers needed to start writing Playwright E2E tests.
Pre-Flight Check
- Check if
e2e/already exists. If so, abort and inform the user — do NOT overwrite an existing test suite. - Check if Playwright is installed. If
@playwright/testis not inpackage.json, add it.
Workflow
Step 1 — Create the Directory Structure
e2e/
├── auth/
│ └── auth.setup.ts
├── fixtures/
│ └── base.ts
├── helpers/
│ └── env-config.ts
├── poms/
│ └── base.page.ts
├── test-data/
├── tests/
│ ├── handover/
│ ├── regression/
│ └── smoke/
├── .auth/ # git-ignored, holds saved session state
├── .gitignore
├── .env.example
├── playwright.config.ts
└── tsconfig.json
Step 2 — Generate Configuration Files
Generate each file using the reference templates:
| File | Template Reference |
|---|---|
playwright.config.ts |
references/playwright-config-template.md |
poms/base.page.ts |
references/base-page-template.md |
fixtures/base.ts |
references/fixtures-template.md |
helpers/env-config.ts |
references/env-config-template.md |
auth/auth.setup.ts |
See e2e-test-conventions skill, references/auth-setup.md |
Step 3 — Generate Support Files
e2e/.gitignore:
.auth/
.env
.env.*
!.env.example
test-results/
playwright-report/
blob-report/
e2e/.env.example:
BASE_URL="https://your-app.example.com"
LOGIN_EMAIL="[email protected]"
LOGIN_PASSWORD="your-password"
AUTH_FILE="e2e/.auth/user.json"
e2e/tsconfig.json:
{
"compilerOptions": {
"target": "ES2022",
"module": "commonjs",
"moduleResolution": "node",
"strict": true,
"esModuleInterop": true,
"skipLibCheck": true,
"forceConsistentCasingInFileNames": true,
"resolveJsonModule": true,
"outDir": "./dist",
"rootDir": "."
},
"include": ["**/*.ts"],
"exclude": ["node_modules", "dist"]
}
What ships with it
4 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.

e2e-test-suite-init is a skill published in the GitHub repository agentmantis/test-skills (12 stars, last pushed 6mo ago), licensed MIT. It adds 82 tokens to every session and 1,033 once invoked, about $0.0003 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.
