Conversation
The ClawHub API v1 version endpoint only returns file metadata (path, size, sha256, contentType) without inline content or download URLs. Our code was looking for inline content in the metadata, which never existed, causing all ClawHub installs to fail with: 'no inline/raw file content was available' Fix: Use the /api/v1/download endpoint (same as the official clawhub CLI) to download skills as ZIP bundles and extract files in-memory. Changes: - Add _download_zip() method that downloads and extracts ZIP bundles - Retry on 429 rate limiting with Retry-After header support - Path sanitization and binary file filtering for security - Keep _extract_files() as a fallback for inline/raw content - Also fix nested file lookup (version_data.version.files)

Problem
hermes skills install steipete/nano-banana-pro(and all other ClawHub skills) fails with:Root Cause
The ClawHub API v1 version endpoint (
/api/v1/skills/{slug}/versions/{version}) only returns file metadata (path, size, sha256, contentType) — it never includes inline content or download URLs. Our_extract_files()method was looking forcontentorrawUrlfields that don't exist in the response.Additionally,
_extract_files()was looking atversion_data.get('files')but the API nests files underversion_data['version']['files'].Fix
Use the
/api/v1/download?slug=X&version=Yendpoint (same as the officialnpx clawhubCLI) to download skills as ZIP bundles and extract files in-memory.Changes:
_download_zip()method — downloads ZIP from/api/v1/download, extracts text files in-memoryRetry-Afterheader support (download endpoint has stricter 20 req/min limit)..traversal prevention) and binary file filtering (500KB cap)version_data['version']['files']in the fallback pathTesting
hermes skills install steipete/nano-banana-pronow succeeds (downloads ZIP, extracts SKILL.md + scripts)
