What

Adds a playwright-verify skill (skills/playwright-verify/SKILL.md) that operationalizes the §4 "use the feature in a browser" rule with real automation, and routes it from CLAUDE.md:

  • Trigger: after any change to a web application (frontend, or a backend change affecting a user-facing web flow), before declaring it done; also when setting up a new web project, where installing the harness is part of setup.
  • Prod-parity local runs, mandated per app repo: a documented one-command way to run locally that mirrors production (same URL contract, headers/proxy topology, build artifacts) - e.g. compose stack with Caddy/nginx standing in for the CDN, MinIO for S3, and built artifacts served statically for static sites, never the dev server alone. make up / make e2e is the preferred convention; creating the harness where missing is part of the task.
  • Verification loop: Playwright against the prod-parity serving path, enforcing a standard checklist (zero console errors; core flows; deep-link cold load restoring state; back/forward; phone-viewport spot-check; network tab free of 404s on app-computed URLs), iterating until clean; deferred findings go to known-issues.md.
  • Selectors/hooks: stable selectors and dev-only window.__app* test hooks gated on the bundler's DEV flag, stripped from prod builds.

CLAUDE.md changes are minimal: one new Skills-table row, and the §4 per-change-type UI/frontend entry now points at the skill (bullet rewrapped to keep the column width).

Verification

scripts/validate-skills.sh passes (5779/7000 chars); all pre-commit hooks pass.

Closes #62

Summary by CodeRabbit

  • Documentation
    • Added guidance for validating web application changes with browser-based testing.
    • Documented production-parity local testing workflows, including startup, validation, and iteration steps.
    • Expanded verification coverage for console errors, core user flows, deep links, navigation history, responsive layouts, and unexpected network activity.
    • Added the new browser verification process to the project’s standard development guidance.

Operationalize the §4 use-the-feature-in-a-browser rule: a skill that runs
Playwright against a mandated prod-parity local stack (make up / make e2e)
after any web-app change, with a standard checklist (zero console errors,
core flows, deep-link cold load, back/forward, phone viewport, network-tab
hygiene) and an iterate-until-clean loop. Route it from the Skills table and
the §4 UI/frontend per-change-type entry.

Closes #62

Review Change Stack

📝 Walkthrough

Walkthrough

The changes add a playwright-verify skill for browser-based web-app validation. CLAUDE.md routes web-app changes to the skill and requires production-parity local-stack testing with Playwright.

Changes

Playwright verification

Layer / File(s) Summary
Define Playwright verification workflow
skills/playwright-verify/SKILL.md
The skill defines Playwright verification triggers, production-parity startup requirements, validation checks, iteration rules, and stable selector guidance.
Route web-app guidance to the skill
CLAUDE.md
The skills table and frontend verification instructions now reference playwright-verify and production-parity local-stack testing.

Estimated code review effort: 1 (Trivial) | ~5 minutes

Merge Risk: 🔵 Low · up to 0556f

This change adds a browser-verification workflow, but the documented command can fetch an unpinned Playwright package when the local dependency is missing, which may reduce reproducibility; the documentation also needs a small formatting cleanup. The PR is mergeable with explicit owner follow-up to make the CLI fail loudly and correct the formatting.

- **Per-change-type**: **UI/frontend** — invoke the `playwright-verify` skill: run the prod-parity
local stack and drive the feature with Playwright, golden path + edge cases; if the project deploys
on push, re-verify in the deployed browser afterwards (local pass ≠ deployed pass). **Backend/API**
— hit the endpoint with `curl` or a test; verify response shape, status codes, error paths.
**Libraries/shared code** — run the suite AND exercise at least one consumer.
**Infrastructure/ops** — staging-first (invoke `infra-ops`). **CI/CD** — simulate locally with
`act` before pushing.

Replace the Unicode U+2014 separators.

This added guidance uses em dashes in the UI/frontend, Backend/API, Libraries/shared code, and Infrastructure/ops entries. Replace each separator with a colon or hyphen to comply with the repository writing rule.

As per coding guidelines: “Never use em-dashes (Unicode U+2014) in generated prose by default.”

2. Run Playwright against that serving path: the project's `make e2e` if present, else
`npx playwright test`.

npm npx documentation --no-install packages not found downloads package behavior

💡 Result:

The --no-install flag in npx is deprecated and is automatically converted to --no [1][2][3]. When you use this flag, npx will attempt to execute a command only if it is already present in your local PATH or your project's node_modules/.bin directory [4][5]. If the requested package is not found in these locations, npx will not attempt to install it [4][5]. Historically, this could result in a vague "canceled" error [6]. In more recent versions of npm, if the command cannot be found and installation is suppressed by this flag, it will fail to execute because the environment constraints (no installation allowed) cannot be met [6]. Key points regarding this behavior: - Deprecation: The --no-install option is deprecated in favor of --no [1][7]. - Execution Scope: It restricts npx to existing binaries, preventing any automated downloading or installation of packages from the npm registry [4][5][8]. - Error Handling: If you encounter an error stating that the process was canceled or that no "YES" option was available, it indicates that the tool you are trying to run is missing from your local environment and your configuration is explicitly forbidding the automatic installation required to fetch it [6]. To resolve a "package not found" error when using this flag, you must either ensure the package is already installed locally or omit the --no-install flag to allow npx to download and execute the package [6].

Use the consuming project's pinned local Playwright CLI.

The fallback npx playwright test can download and execute a package when the local CLI is missing. Require a locked local Playwright dependency and use npx --no playwright test so missing dependencies fail loudly.

[warning] 36: [RP1] null: npx commands without a version suffix (e.g. @1.0.0) create a rug-pull risk if the upstream server is compromised and publishes a malicious update.

Remediation: Pin the version: npx @scope/server@1.2.3

(MCP Rug Pull (RP1))


[warning] 30: [EA2] Autonomous Decision Making: Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.

Remediation: Add human-in-the-loop confirmation for destructive, irreversible, or high-impact operations. Never auto-execute commands that modify files, send data, or alter system state.
