SourceCraft Publisher

Publish already-built static artifacts to a SourceCraft Sites repository. Works from Russia (Yandex infrastructure).

This skill is the deployment/output layer for page artifacts created by other skills (e.g. telegram-channel-parser digest).

Required repository layout

Every published artifact must go into this path shape inside the target repo:

<year>/<year>-<month>/<page-slug>/

Example:

• 2026/2026-03/ai-digest-week/

Never publish flat at repo root. Never skip the year or year-month nesting.

What this skill expects

Input should already exist as one of these:

• a folder of built static files
• a single HTML artifact plus local assets
• a small static site ready to serve from a subdirectory

This skill does not do frontend design work. It packages and publishes what already exists.

Config

Read config/README.md for required environment variables and token setup.

cp config/.env.example config/.env

Required: SOURCECRAFT_TOKEN, SOURCECRAFT_REPO, SOURCECRAFT_SITE_URL.

Workflow

1. Determine the publish date bucket:

• year = YYYY
• year-month = YYYY-MM

1. Create or update target directory:

• <year>/<year-month>/<page-slug>/

1. Copy artifact files into that directory
2. Verify there is an entrypoint (index.html normally)
3. Ensure .sourcecraft/sites.yaml exists in repo root
4. Commit and force-push to the SourceCraft repo
5. Return the final public URL

Publishing command

python3 scripts/publish_static.py --source <dir-or-html> --slug <name> [--date YYYY-MM-DD] [--image-max-kb 500]

The script:

• Clones the SourceCraft repo (shallow)
• Ensures .sourcecraft/sites.yaml config exists
• Copies artifact into YYYY/YYYY-MM/slug/
• Optimizes oversized .jpg, .jpeg, .png, and .webp images before commit
• Commits and force-pushes
• Prints the final public URL

Image optimization

Image optimization is a recommendation, not a hard requirement. By default, the publishing script tries to keep each raster image under 500KB by stripping metadata, recompressing, and resizing long edges when needed.

Use --image-max-kb <kb> for a different target. Use --keep-large-images or --image-max-kb 0 when the user explicitly needs original-size images (for example, a full-resolution infographic, map, or downloadable media asset).

The original --source artifact is not changed. Optimization happens only after files are copied into the publish repo target directory. If Pillow/uv is unavailable or optimization fails, continue publishing originals and mention the warning.

Manual console run for a prepared artifact:

uv run --with pillow python3 scripts/optimize_images.py <artifact-dir> --max-kb 500

Slug rules

• use lowercase letters, digits, and hyphens
• keep it short and descriptive
• avoid spaces, underscores, Cyrillic

URL contract

Always return the final public URL: <SOURCECRAFT_SITE_URL>/<year>/<year>-<month>/<page-slug>/

Pre-publish validation

Before pushing, verify:

• artifact has index.html entrypoint
• oversized raster images are optimized when practical, unless original-size sharing is intentional
• no absolute local paths in HTML/CSS
• no secrets in files
• all local assets reachable from the target folder

Safety rules

• do not delete unrelated directories in the repo
• only replace contents of the target page directory
• if overwriting, say so in the result
• do not expose the token in output, logs, or committed files
