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.

SkillSpector: 3 findings, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00089 | $0.01070 |
| Opus 5 | $0.00044 | $0.00535 |
| Sonnet 5 | $0.00018 | $0.00214 |
| Haiku 4.5 | $0.00009 | $0.00107 |
Grade A, and why
playwright-regression-testing 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 11d 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 Regression Testing (TypeScript)
Strategy and best practices for automated regression testing of web applications using Playwright with TypeScript.
Activation: This skill is triggered when working with regression test strategy, test suite selection, test prioritization, CI/CD pipeline testing, flaky test management, test sharding, or optimizing test execution for web applications using Playwright.
When to Use This Skill
- Plan regression suites with risk-based and change-based test selection
- Organize tests into tiers (smoke, sanity, selective, full regression)
- Optimize execution with parallelization, sharding, and time-budget strategies
- Integrate with CI/CD using GitHub Actions pipelines
- Manage flaky tests with quarantine, retry policies, and root cause tracking
- Monitor suite health with execution time, flake rate, and detection metrics
- Select tests after changes using git diff analysis and impact mapping
Do NOT Use For
- Authoring a single UI spec or page-object model (use
playwright-e2e-testing). - Driving a live browser interactively for debugging (use
playwright-cli). - Selenium/Java regression suites (use
webapp-selenium-testing). - API contract testing in isolation (use
api-testing).
Prerequisites
| Requirement | Details |
|---|---|
| Node.js | v18+ recommended |
| Playwright | @playwright/test package |
| TypeScript | typescript configured in project |
| Browsers | Installed via npx playwright install |
| Git | Required for change-based test selection |
| GitHub Actions | Recommended CI/CD platform |
Quick Reference
Tiers: Smoke (<2min, every commit) → Sanity (<10min, every PR) → Selective (<30min, on merge) → Full (<60min, nightly/pre-release).
Key tags: @smoke, @sanity, @regression, @e2e, @api, @destructive — exactly one per test, never on describe() blocks. Domain-specific extensions (e.g., @a11y in accessibility skills) are allowed alongside, but only one execution tag per test.
What ships with it
7 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.

playwright-regression-testing is a skill published in the GitHub repository fugazi/test-automation-skills-agents (234 stars, last pushed 8d ago), licensed MIT. It adds 89 tokens to every session and 1,070 once invoked, about $0.0004 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 2026-08-30.
