Run headless browser smoke and E2E tests for scaffolded web services. Use when verifying rendered web UI, checking browser errors, creating Playwright-style scenarios, collecting screenshots, or testing a deployed/local service through Chromium.

Explicit-only Docker deploy. Run this skill's bundled scripts/deploy.sh directly; do not search for skills, inspect trees, or use subagents.

Use only when explicitly invoked as $web-service-scaffold to run the bundled web-service scaffold script.
Use when a goal should be split across multiple queued session turns with reflection turns between work turns.
Enforce the repository package documentation contract as a navigable dependency graph. Use when creating or updating package README, docs pages, navigation tables, architecture router, API docs, usage docs, constraints, blast-radius/consumer records, internals, decisions, or testing docs. Docs exist so a later model drills down from task to edit target with minimal context and sees blast radius before editing. Keep content terse; keep only repo-specific contracts, paths, edges, intent, and decisions.
Enforce the repository Docker contract: Docker-first runtime, one root docker-compose.yml, module-owned Docker assets, apps service-module to container mapping, isolated networking, Docker socket passthrough for container-spawning services, a standard npm deploy entrypoint, and runtime-only Dockerfiles that copy prebuilt local dist artifacts instead of building the project. Use when defining compose services, Dockerfiles, networks, volumes, env_file wiring, deploy scripts, Docker socket access, or container ownership.

Use scripts first. This skill is for the NDX agent running inside its Docker runtime to test a project created or managed by NDX. Keep prompts short; let the checked scripts enforce browser setup, URL handling, artifacts, trace capture, and report shape.
