Setup Quality Ci

Quality CI

Instructions

Generate a GitHub Actions workflow that enforces code quality and test coverage on every pull request: $ARGUMENTS. $ARGUMENTS may specify the branch, workflow name, or special requirements.

Nexa Rules Gate

Read and follow ${CLAUDE_PLUGIN_ROOT}/shared/readiness/NEXA_RULES_GATE.md.

Prerequisites

• The project must have oxlint and oxfmt in devDependencies (use /code-quality first if needed)
• The project must have vitest with coverage configured in vitest.config.ts (use /vitest-test first if needed)
• The project must have an oxlintrc.json at the root with the eslint/complexity rule

Workflow

1. Read the project context:

• Verify oxlintrc.json exists in the project root
• Verify vitest.config.ts exists and has coverage configured with thresholds
• Read package.json to determine the Node.js version and check that oxlint, oxfmt, and @vitest/coverage-v8 are in devDependencies
• Check for any existing GitHub Actions workflows in .github/workflows/
• Ask the user for: workflow trigger branch (default: main), whether to also trigger on pull requests (default: yes)

1. Create the GitHub Actions workflow at .github/workflows/quality.yml using the template.

Fill in the template placeholders:

| Placeholder | Description | Default | |---|---|---| | {{NODE_VERSION}} | Node.js version from package.json engines field or .nvmrc | 22 | | {{BRANCH}} | Branch that triggers the workflow | main |

Ensure the following are present in the generated workflow:

• Concurrency: The concurrency key must cancel in-progress runs for the same branch/PR to prevent redundant CI billing
• Package manager detection: Detect the package manager from the lockfile (package-lock.json → npm, pnpm-lock.yaml → pnpm, yarn.lock → yarn) and pass it to actions/setup-node's cache parameter
• Coverage report upload: The coverage job must use actions/upload-artifact to save the Vitest HTML report from coverage/

1. Verify the workflow file:

• Validate YAML syntax by reading the file back
• Ensure no placeholder {{...}} markers remain
• Ensure the workflow file is under 80 lines

1. Output a summary with:

• What was created and where
• How the workflow triggers (push, PR, or both)
• What each job checks (lint job: oxlint + oxfmt, coverage job: vitest --coverage)
• Reminder: the coverage job will fail if any metric drops below the thresholds in vitest.config.ts

Reference Templates

• GitHub Actions workflow: [templates/github-actions/quality.yml](templates/github-actions/quality.yml)

Workflow Template Placeholders

| Placeholder | Description | Example | |---|---|---| | {{NODE_VERSION}} | Node.js major version | 22 | | {{BRANCH}} | Branch that triggers the workflow on push | main |

Design Decisions

Two separate jobs: lint and coverage

The lint job runs oxlint and oxfmt — these are fast (seconds) and have no external dependencies. The coverage job runs Vitest with coverage — this needs Docker for Testcontainers and takes longer. Splitting them gives faster feedback: a formatting issue fails in ~30 seconds instead of waiting for the full test suite.

Why v8 coverage, not istanbul

The v8 provider uses V8's built-in code coverage, which is faster and requires no code instrumentation. It is Vitest's recommended provider for Node.js environments.

Coverage thresholds fail the CI job

The vitest.config.ts defines thresholds (statements, branches, functions, lines at 80%). When npx vitest run --coverage detects coverage below these thresholds, it exits with a non-zero code, which fails the GitHub Actions job. No additional threshold checking is needed in the workflow — Vitest handles it natively.

Update CLAUDE.md

After creating the workflow, append a ## Quality CI section to the target project's CLAUDE.md so that future sessions know CI is configured.

1. If CLAUDE.md does not exist, create it
2. If a ## Quality CI section already exists (check for ``),

ask the user whether to overwrite or skip

1. Append the following section (fill in the actual values from the setup):

~~~markdown

Quality CI

• Workflow: .github/workflows/quality.yml
• Triggers: push to [branch], pull requests to [branch]
• Lint job: oxlint (with complexity rule) + oxfmt --check
• Coverage job: vitest run --coverage (v8 provider, 80% thresholds)
• Artifacts: coverage report uploaded on every run

~~~

Do not remove or modify any other content in CLAUDE.md.

DO NOT

• Combine lint and coverage into a single job — they have different performance profiles and dependencies
• Hard-code the Node.js version — read it from the project's package.json or .nvmrc
• Hard-code the package manager (npm/pnpm/yarn) — detect it from the lockfile present in the project root
• Omit the concurrency key — we must prevent redundant CI billing on rapid pushes
• Skip actions/setup-node caching — speed is a priority for the Nexa ecosystem
• Add matrix strategies for multiple Node versions or OS — keep the workflow single-purpose
• Add deployment steps or notifications — this workflow is only for quality gates
• Overwrite an existing .github/workflows/quality.yml without reading it first and asking the user
• Add ESLint or Prettier steps — the project uses Oxc (oxlint + oxfmt) exclusively
