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 | $0.05358 | $0.05358 |
| Opus 5 | $0.02679 | $0.02679 |
| Sonnet 5 | $0.01072 | $0.01072 |
| Haiku 4.5 | $0.00536 | $0.00536 |
Grade A, and why
e2e-skills AGENTS.md 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.

Repository Overview
e2e-skills is a bundle of four Agent Skills for end-to-end test work on Playwright and Cypress projects:
playwright-test-generator— generates Playwright E2E tests from scratch (coverage-gap analysis → live-browser exploration → approval gate → review).e2e-reviewer— static review of existing Playwright/Cypress specs against 24 anti-patterns grouped P0/P1/P2.playwright-debugger— root-cause diagnosis fromplaywright-report/.cypress-debugger— root-cause diagnosis fromcypress/reports/(mochawesome / JUnit).
The repo doubles as a Claude Code plugin (.claude-plugin/), a Codex plugin (.codex-plugin/), a cross-agent skill source via the skills CLI, and a standalone scanner (skills/e2e-reviewer/scripts/scan.sh).
Verification gate (must pass before commit)
[ ] /bin/bash -p scripts/ci/ci-local.sh # review checks + drift smoke checks + 0 P0 smell hits
[ ] /bin/bash -p scripts/ci/pre-push-security.sh # secrets and credential leak guard
ci-local.sh is the single source of truth for the repository CI mirror
(shell syntax, security, parity, evals, public skill surface, framework scope,
link integrity, docs orphan check, language, and the E2E smell scan).
ci-local.sh reaches the security gate through review.sh; the explicit
pre-push-security.sh command above reruns that mandatory gate at the
pre-push boundary. If you change a CI check, update ci-local.sh first.

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-skills AGENTS.md is an instructions file published in the GitHub repository voidmatcha/e2e-skills (10 stars, last pushed 4d ago), licensed Apache-2.0. It adds 5,358 tokens to every session, about $0.0268 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.
