description	Build, edit, validate, and troubleshoot Hugo static sites. Use when working with Hugo repositories, including config.toml/config.yaml/hugo.toml, content front matter, archetypes, layouts, partials, shortcodes, taxonomies, menus, assets, image processing, RSS/search outputs, redirects, or static-site deployment.

Hugo

Use this skill for Hugo static-site work: content changes, template/layout edits, taxonomy and menu updates, asset pipeline changes, data files, shortcodes, render hooks, redirects, and deployment validation.

First Pass

Before editing, inspect the project shape:

• Read repository instructions such as AGENTS.md, .codex/config.toml, and relevant README files.
• Identify the Hugo config file: hugo.toml, config.toml, hugo.yaml, config.yaml, hugo.json, or a config/ directory.
• Check for a theme, module, or local layouts: themes/, layouts/, assets/, static/, data/, content/, archetypes/, i18n/.
• Check the build/deploy path: package.json, go.mod, .github/workflows/, netlify.toml, vercel.json, wrangler.*, Cloudflare Pages docs, Makefile, or project scripts.
• Run or inspect hugo version when validation depends on version-specific behavior.
• Inspect git status --short and preserve unrelated user changes.

Common Commands

Use the repository's existing scripts when present. Otherwise prefer:

hugo server
hugo server --buildDrafts --buildFuture
hugo --gc --minify
hugo --printPathWarnings --printUnusedTemplates

Use --source, --config, --environment, or --destination only when the repository structure requires them.

Content Work

• Use existing archetypes and nearby content as the model for new pages or posts.
• Preserve explicit url, slug, aliases, and redirect behavior unless the task is specifically about URL changes.
• Keep front matter format consistent with the file or project: TOML, YAML, or JSON.
• Preserve taxonomy spelling and casing used by existing content.
• For posts, verify required fields such as title, date, draft, description, summary, image, categories, tags, author, or custom params by checking templates and archetypes.
• Use <!--more--> only when existing list templates or content conventions rely on manual summaries.
• Avoid broad rewrites of historical content unless requested.

Template Work

• Prefer existing partials, base templates, render hooks, shortcodes, and CSS patterns over one-off markup.
• Identify template lookup rules before moving or renaming files. Section/type-specific templates can be intentional.
• Treat these as high-impact files because they often affect many pages: baseof.html, head/meta partials, navigation/header/footer partials, list/single templates, RSS templates, sitemap templates, search index templates, and structured-data partials.
• Preserve SEO and sharing behavior: canonical URLs, Open Graph, Twitter cards, JSON-LD, RSS, sitemap, and robots output.
• Preserve accessibility affordances such as semantic headings, skip links, focus states, useful alt text, labels, and keyboard-accessible controls.
• For shortcodes, keep positional/named parameter compatibility unless a breaking change is requested.

Assets And Data

• Understand the asset boundary:
  • assets/ is processed by Hugo Pipes.
  • static/ is copied directly to the published site.
  • public/ is generated output and is usually not source.
• For SCSS, JS, fonts, and images, follow the existing pipeline rather than adding a new package manager or bundler.
• For image processing, check config and template use of .Resources, resources.Get, Fit, Fill, Resize, WebP, and fingerprinting before changing paths.
• For data/ files, keep JSON/YAML/TOML valid and preserve the shape consumed by templates.
• Do not commit secrets, API keys, private tokens, or generated credentials in data files, templates, scripts, or build logs.

Hugo Modules And Themes

• If the site uses Hugo Modules, inspect go.mod, go.sum, and module imports in config before editing theme files.
• If the site uses a theme under themes/, prefer overriding templates in the project layouts/ directory unless the task requires changing the theme source.
• If the site vendors a theme or has no external theme, treat local templates and assets as first-party source.

Multilingual Sites

When languages, defaultContentLanguage, i18n/, or language-specific content directories are present:

• Preserve translation keys and language-specific URL rules.
• Check whether menus, params, taxonomies, and permalinks are language-specific.
• Validate at least one representative page per affected language when practical.

Deployment

Match validation to the deployment target:

• Cloudflare Pages commonly runs hugo or a project script and publishes public/.
• Netlify may use netlify.toml, environment variables, and a pinned Hugo version.
• GitHub Pages may deploy through Actions and may require base URL or artifact settings.
• Vercel or custom hosts may wrap Hugo in package scripts.

Do not change deployment commands, publish directories, Hugo versions, or environment assumptions without checking the existing deployment config.

Validation

For most changes, run:

hugo --gc --minify

For content scheduled in the future or drafts:

hugo server --buildDrafts --buildFuture

For high-impact template or URL changes, also inspect representative generated pages or run a local server and check:

• Home page.
• A single content page.
• A list page.
• A taxonomy page.
• Search or JSON output if present.
• RSS or sitemap if touched.
• A page using any changed shortcode/render hook.

Report validation commands run, failures, skipped checks, and residual risks.
