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 | $0.00101 | $0.05411 |
| Opus 5 | $0.00051 | $0.02705 |
| Sonnet 5 | $0.00020 | $0.01082 |
| Haiku 4.5 | $0.00010 | $0.00541 |
Grade A, and why
write-e2e 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.
How it starts
The opening of the file, as written. The whole thing — 290 lines — stays where its author put it; the contents beside it link to each section on GitHub.
zuvo:write-e2e — E2E Test Generation
Discover routes and user flows, rank them by criticality, generate Playwright specs that assert causality, and — when
the project can actually run Playwright — execute them and report exactly what was proven; a spec is a draft until a
state on the verification ladder says otherwise. Scope: web apps with routes, forms, interactions. Out of
scope: unit tests (zuvo:write-tests), a suite audit (zuvo:test-audit), diagnosing flaky specs (zuvo:debug), batch anti-pattern repair (zuvo:fix-tests).
Argument Parsing
Parse $ARGUMENTS as: [--scope <path>] [--flow <name>] [--output <dir>] [--base-url <url>] [--max-flows N] [--live] [--auto] [--flows] [--dry-run] [--no-install] [--allow-external-origin] [--allow-destructive <ops>]
| Argument | Mode | Flows | Description |
|---|---|---|---|
--scope <path> |
SCOPED | 1 | Restrict discovery to one app root, directory or route file |
[path] |
SCOPED | 1 | Deprecated positional alias for --scope — accepted, but prefer --scope <path> |
--flow <name> |
NAMED | 1 | Generate exactly the named flow |
--output <dir> / --base-url <url> |
OUTPUT / TARGET | — | Write specs under <dir> instead of the detected E2E root / name the origin the specs target, classified in Phase 0.5 before any request |
--max-flows N |
LIMIT | N | Explicit flow budget — the only way to ask for a large batch, 20 included |
--live |
LIVE | — | Permit live DOM/locator inspection against a permitted origin |
--auto |
AUTO | 3 | Skip the selection prompt; take the highest-scored flows |
--flows / --dry-run |
DISCOVER / PREVIEW | 0 | Print the scored list and stop / plan through scaffold and write nothing |
--no-install |
NO-BOOTSTRAP | — | Forbid the BOOTSTRAP_REQUIRED dependency materialization (env alias: ZUVO_E2E_NO_BOOTSTRAP=1); the run caps at STATIC_CHECKED and verdict WARN |
--allow-external-origin |
CONSENT 1 | — | Permits READ-ONLY execution against a non-local origin, and is the only thing (besides an exact ZUVO_E2E_STAGING_HOSTS match) that classifies an origin STAGING. Grants nothing mutating |
--allow-destructive <ops> |
CONSENT 2 | — | Authorizes the named mutating operations only, comma-separated. Independent of consent 1 — neither implies the other, and an unnamed operation stays BLOCKED |
What ships with it
6 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.
- 2d ago First seen · 290 lines · 101 tokens per session scan A bf3e035eb84e
write-e2e is a skill published in the GitHub repository greglas75/zuvo (6 stars, last pushed yesterday), licensed MIT. It adds 101 tokens to every session and 5,411 once invoked, about $0.0005 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.
Other skills, from other repositories
browser-check
Drive a real browser and come back with a MEASUREMENT rather than an impression - console errors and >=400 responses as counts, computed styles as JSON when appearance is disputed. Use when work touches UI, when a review must verify one, or when fidelity-gate asks for its measurement.
test-site
Tests a deployed, activated Power Pages site at runtime using browser-based navigation, page crawling, and API request verification via Playwright. Use when the user wants to test, verify, or smoke-test their deployed site.
browser-smoke-review
Use browser automation to review docs pages, preview URLs, rendered output, or web-facing fallow surfaces. Use when the user wants a screenshot-based review, browser smoke test, docs site check, or preview deployment inspection.
qa
Browser-based QA verification. Launches a real browser, navigates the app, clicks buttons, fills forms, and tests user flows. Works as a standalone skill or as a phase end condition in campaigns. Requires Playwright (optional dependency, graceful skip if not installed).
browser-qa
自动化视觉测试与 UI 交互验证。部署功能后使用浏览器自动化验证关键页面、核心路径和发布前回归。 当任务需要真实浏览器验证渲染、导航、交互或前端上线风险时使用。.
integration-e2e-testing
Integration and E2E test design principles, ROI calculation, test skeleton specification, and review criteria. Use when designing integration tests, E2E tests, or reviewing test quality.
