symfony:e2e-panther-playwright

symfony:e2e-panther-playwright is a skill for Claude Code from dev-toolings/superpowers-symfony. It costs 31 tokens per session (241 once invoked), scanned A, original, MIT.

A Symfony testing guide for browser-based end-to-end tests using Panther or Playwright. End-to-end tests check complete user flows through the application, often in a real browser.

In plain words
What is it for?
It helps write failing tests, implement the smallest fix, and then refactor safely. It covers browser automation, regression tests, and more complex Playwright scenarios.
Why use it?
It turns bug reports and desired behavior into repeatable tests and helps catch failures at boundaries such as invalid, unauthorized, or missing requests.

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

symfony:e2e-panther-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 9d 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

E2e Panther Playwright (Symfony)

Use when

  • Building regression-safe behavior with TDD/functional/e2e tests.
  • Converting bug reports into executable failing tests.

Default workflow

  1. Write failing test for target behavior and one boundary case.
  2. Implement minimal code to pass.
  3. Refactor while preserving green suite.
  4. Broaden coverage for invalid/unauthorized/not-found paths.

Guardrails

  • Prefer deterministic fixtures/builders.
  • Assert observable behavior, not internal implementation.
  • Keep tests isolated and stable in CI.

Progressive disclosure

  • Use this file for execution posture and risk controls.
  • Open references when deep implementation details are needed.

Output contract

  • RED/GREEN/REFACTOR trace.
  • Test files changed and executed commands.
  • Coverage and confidence notes.

References

  • reference.md
  • docs/complexity-tiers.md
Files

What ships with it

1 file 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.

Changes

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.
