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 | $0.00167 | $0.02507 |
| Opus 5 | $0.00084 | $0.01254 |
| Sonnet 5 | $0.00033 | $0.00501 |
| Haiku 4.5 | $0.00017 | $0.00251 |
Grade A, and why
e2e-remote-setup 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 8d 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 — 166 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Remote E2E setup (crabbox + E2B)
Turn a focus-stealing local E2E suite into one that runs on a remote headless Linux
box. Electron E2E (Playwright _electron.launch) opens a real OS window that grabs
mouse/keyboard on the dev machine — there's no local headless display for a full Electron
app. This skill wires up crabbox to lease an E2B sandbox, rsync the working tree,
install deps, and run the suite under Xvfb (an in-RAM X display), streaming results
back. The developer's local focus is never touched.
The end state is a single command:
pnpm test:e2e:remote # runs the E2E suite on a remote box, no local focus stealing
When to use / not use
- Use for a suite that boots a real GUI app locally (Electron via
_electron.launch; any Playwright/WebdriverIO suite that opens a non-headless window). Also the right tool when local CI can't run the GUI suite and you want an on-demand remote runner. - Don't use for already-headless browser tests (
playwright testagainst headless Chromium runs fine locally/in CI) — there's nothing to offload.
Prerequisites (check first, install/guide as needed)
- crabbox CLI —
crabbox --version. If missing, tell the user to install it (it's the orchestrator that leases the sandbox, rsyncs, and execs). The skill assumes crabbox is already available on the machine (it was, in the source project). - E2B account + CLI —
e2b --version; auth viae2b auth login. E2B is brokerless, per-second billing, fast boot. The run reads the team key from~/.e2b/config.json(never passed as a CLI arg — seerun.sh). - A runnable E2E script in the target repo (e.g.
test:e2e→playwright test). You will wrap THIS command; find its exact form (checkpackage.jsonand, if present, the CI workflow's E2E step — mirror that recipe so remote == CI).
Setup steps
Copy the three bundled templates into the target repo and adapt them. All live under this
skill's templates/ directory.
What ships with it
3 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-remote-setup is a skill published in the GitHub repository kellykampen/agent-skills (2 stars, last pushed 1mo ago), licensed MIT. It adds 167 tokens to every session and 2,507 once invoked, about $0.0008 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.
