In plain words
What is it for?
Use it for end-to-end browser tests, API tests, screenshots, videos, parallel test runs, and HTML test reports.
Why use it?
It provides a governed way to run browser and API tests, capture evidence, and track reports while requiring human approval.

Written for no agent in particular: nothing here depends on one. Also seen: installed under .agents/ (shared by several agents).

This is layer1labs/specsmith's own configuration. It tells Claude Code and Codex how to work on specsmith itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything specsmith configures →

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

playwright-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 2mo 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.

What it actually says

Playwright Testing Framework

This skill enables specsmith projects to use Playwright for end-to-end browser testing while maintaining governance compliance.

Requirements Covered

  • REQ-101: Playwright Testing Framework
  • Allows specsmith projects to use Playwright for end-to-end browser testing with human approval

Integration Capabilities

Framework Features

  • End-to-end browser testing with Playwright
  • Cross-browser testing (Chromium, Firefox, WebKit)
  • API testing capabilities
  • Screenshot and video capture
  • Parallel test execution
  • Test reporting and analytics

Governance Requirements

  • Human approval required for all Playwright testing
  • Configuration management with governance controls
  • Test artifact management with approval
  • Reporting and coverage tracking with approval

Usage Examples

# Initialize Playwright testing
specsmith skill install playwright-testing

# Configure Playwright settings
specsmith playwright configure --browser chromium --timeout 30000

# Run end-to-end tests
specsmith playwright run --test-suite e2e-tests

# Generate test reports
specsmith playwright report --format html

Configuration

The skill requires the following configuration in scaffold.yml:

playwright:
  browser: chromium
  timeout: 30000
  headless: true
  parallel: true
  screenshot: "on_failure"

Security Considerations

  • All Playwright testing requires human approval
  • Test environment isolation must be maintained
  • Sensitive data handling in tests must be secured
  • Test artifact access controls must be enforced

Compliance Requirements

  • Follow security best practices for testing environments
  • Maintain audit logs of all Playwright test executions
  • Ensure proper test artifact management and retention
  • Generate and track test coverage reports

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.
