Validation and Build — HALOS

Help users validate the spec, build the site, and use Docker. Per halos-repo-operations, run validation and build before committing.

When to Use

• Validation errors (schema, generate-spec)
• Build failures (Jekyll, Docker)
• Docker commands or image issues
• Questions about local dev (serve, scripts)

Validation

Commands

Docker (recommended):

docker run --rm halos validate
# With local changes:
docker run --rm -v "$(pwd):/workspace" halos validate

Local:

npx --yes ajv-cli validate --spec=draft2020 -s spec/schema/manifest.schema.json -d spec/manifest.json
npx --yes ajv-cli validate --spec=draft2020 -s spec/schema/core.schema.json -d spec/core.json
npx --yes ajv-cli validate --spec=draft2020 -s spec/schema/changelog.schema.json -d spec/changelog.json
node scripts/validate-spec-immutability.js origin/main
node scripts/generate-spec.js
test -s spec/spec.md && test -s spec/CHANGELOG.md

Pre-push immutability check:

node scripts/validate-spec-immutability.js origin/main

Common Errors

• Schema validation fails — Check JSON syntax; ensure required fields in manifest, core, changelog; run node scripts/generate-spec.js after JSON edits
• spec.md / CHANGELOG.md missing — Run node scripts/generate-spec.js from repo root
• ajv-cli not found — Use npx --yes ajv-cli or Docker

Build and Serve

Docker

# Build site
docker run --rm halos build

# Serve (builds then serves on 3000)
docker run --rm -p 3000:3000 halos serve

# Info (version, bundled vs mounted)
docker run --rm halos info

Local Script

./scripts/serve.sh

Requires: Jekyll, Python 3. Copies spec and agents into docs, runs jekyll build, serves docs/_site on port 3000.

Common Build Errors

• Jekyll / Sass errors — Ensure Ruby, bundle; check docs/_config.yml
• spec/spec.html not built — Ensure spec/ was copied to docs/ (script does this; Docker build does too)

CI Workflows

• spec-validate.yml — Schema validation, generate-spec, verify outputs
• deploy-pages.yml — Build site, deploy to GitHub Pages
• docker-build.yml — Build and push Docker image

Integration tests

./scripts/integration-test.sh

Spins up the site in Docker, checks all paths (200s, expected content), verifies 404 for unknown paths. Run before committing or deploying. CI runs this as a pre-deploy gate.

Before Committing

Per halos-repo-operations:

• Run validation (Docker or local)
• Run build and verify key pages if changing docs/spec
• No secrets in committed files; pinned dependencies
