What is it for?
Writing Playwright end-to-end tests for Next.js and Fastify projects.

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

e2e-playwright 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 22d 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.

Playwright patterns: @.agents/skills/playwright

Config

  • Frontend apps (apps/web) use Playwright E2E only — no Vitest/Testing Library unit or integration tests
  • No webServer; URLs from PLAYWRIGHT_APP_URL / PLAYWRIGHT_API_URL (env or --app / --api params)
  • Fastify: only --api param; test:e2e = URL-based, test:e2e:local = spawn API, poll, run, cleanup
  • Param format: --app=URL or --app URL, --api=URL or --api URL
  • CI: test:e2e:local only (spawn local servers; no Vercel URLs). Loopback http://localhost:3000 / :3001 — Portless is skipped in CI (no sudo/CA). Eve is not in the Playwright DAG; spawn pins EVE_COMMAND_URL / EVE_CHAT_URL to http://127.0.0.1:3004 / :3005.
  • Local: Next test:e2e:local = spawn Fastify + Next, poll, run all projects, kill. Fastify test:e2e:local = spawn API only. Root pnpm test:e2e = run both via scripts/run-e2e.mjs
  • workers: 1, fullyParallel: false — PGLite does not support concurrent writers; tests must run in series
  • Do not filter --project= in spawn scripts; run the full project DAG
  • Local/CI API spawn sets ALLOW_TEST=true, RATE_LIMIT_MAX=10000, and COINS_RATE_LIMIT_MAX=10000 (default API limit is 100/min per IP; GET /coins defaults to 10)
  • Local/CI API spawn sets COINS_USE_FIXTURE=true so GET /coins uses checked-in fixture quotes
  • Local/CI API spawn sets WEBAUTHN_RP_NAME=Test App when unset (passkey registration requires an RP display name)
  • Confirm dialogs use getByRole('alertdialog') (shadcn AlertDialog), not dialog

Projects (dependency graph)

public → auth → setup → {chromium, security, passkey-login}

  • public: no storageState
  • auth: empty storageState; numbered 01-…06- specs (file-name order is the convention — testMatch only selects files, it does not impose execution order)
  • setup: auth.setup.ts writes test-results/.auth/user.json (depends on auth)
  • chromium / security: storageState from setup file
  • passkey-login: empty storageState; dedicated [email protected]

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.
