Phase D of v2.3 template configuration — closes the loop between the Swift app and the catalog pipeline. Authors can now ship schemaful bundles; the Python validator enforces the same invariants the Swift installer does; the catalog site displays the schema so visitors see what they'll need to configure before installing. Python validator (tools/build-catalog.py): - SUPPORTED_SCHEMA_VERSIONS accepts both 1 and 2 (v1 bundles are unchanged; v2 adds optional manifest.config). - New _validate_config_schema function mirrors the Swift ProjectConfigService.validateSchema rules: unique keys, supported types, enum option presence + unique values, list itemType == "string", secret-field cannot declare a default, modelRecommendation.preferred non-empty when present. - _validate_contents_claim cross-checks contents.config (field count) against config.schema actual length — mismatch refused. - TemplateRecord.to_catalog_entry exposes `config` in catalog.json so the site can render the schema. - render_site copies each bundle's template.json to the detail dir as manifest.json (only when the manifest has a config block — keeps the served tree lean and makes "no manifest.json" a meaningful 404 signal in the frontend). - catalog.json's own schemaVersion stays at 1 (independent of per- template manifest schemaVersion). Python tests (tools/test_build_catalog.py): 8 new cases in a new ConfigSchemaValidationTests suite — accepts schemaful bundle, rejects duplicate keys, rejects secret-with-default, rejects enum-without- options, rejects unsupported field type, rejects contents.config count mismatch, rejects unsupported list itemType, legacy v1 manifests pass unchanged. 24/24 Python tests total. Site (site/widgets.js): - New renderConfigSchema(container, config) — mirrors the display on the Scarf install preview. Renders each field as a <dt>/<dd> pair with type + required badges; enum shows choice labels; list fields show min/max bounds; string fields show pattern/length; secret fields get a "Stored in Keychain" reassurance. Optional modelRecommendation panel at the bottom with preferred + rationale + alternatives. - The renderer is display-only — the site never collects values; that's the Scarf app's job. template.html.tmpl adds a #config-schema <section>. The inline script fetches manifest.json from the detail dir; on success hands the config block to ScarfWidgets.renderConfigSchema; on 404 (schema-less templates) silently leaves the section empty. CSS in styles.css adds a config-schema panel matching the accent-green aesthetic. 24/24 Python + 50/50 Swift tests pass. site-status-checker still renders correctly (schema-less; manifest.json isn't copied for it).

Scarf Templates
The community template catalog for Scarf — a macOS GUI for the Hermes AI agent. Each subdirectory here is one installable project template. Browse the live catalog with live dashboard previews at https://awizemann.github.io/scarf/templates/.
What's a template?
A .scarftemplate bundle ships:
- A pre-configured project dashboard (widgets for stats, lists, text, charts).
- A cross-agent
AGENTS.md(agents.md standard) that tells Claude Code, Cursor, Codex, Aider, Jules, Copilot, Zed, etc. how to work with the project. - Optional skills, cron jobs, optional per-agent instruction shims (
CLAUDE.md,GEMINI.md,.cursorrules,.github/copilot-instructions.md), and an optional memory appendix.
Users install with one click from the catalog site or by opening a .scarftemplate file in Scarf.
Layout
Each template lives at templates/<github-handle>/<template-name>/ with:

├── staging/ source tree
│ ├── template.json manifest (id, name, version, contents claim)
│ ├── README.md shown on catalog detail page
│ ├── AGENTS.md required cross-agent instructions
│ ├── dashboard.json rendered as a live preview on the catalog site
│ ├── instructions/… optional per-agent shims

│ ├── cron/jobs.json optional cron job definitions
│ └── memory/append.md optional memory appendix
├── <template-name>.scarftemplate built bundle (zipped staging/), committed as-is

The built .scarftemplate is served directly from raw.githubusercontent.com — the catalog's Install button links at:

Contributing a template
See CONTRIBUTING.md for the full submission walkthrough. tl;dr: fork, drop a template under templates/<your-handle>/<your-name>/, open a PR. A CI check validates the bundle; a maintainer reviews the content.
Catalog metadata
catalog.json at this directory is the aggregate index that the website reads. It's regenerated by the maintainer on merge — do not modify it in your PR, the build script will take care of it.
