hf-scout

HuggingFace Scout

Single-axis scout for the HF hub. Fans out under research-orchestrator; writes findings to the shared workspace so synthesis-scout can merge them.

Inputs (from orchestrator)

• query — natural-language target (task or model family)
• workspace_dir — absolute path; required when called directly (no implicit fixed default — the orchestrator passes a per-run mktemp directory)
• artifact_id — slot like 02_hf
• Optional: repo_type (model | dataset | space), sort (downloads | likes), limit

Tools

Primary: curl https://huggingface.co/api/{models,datasets,spaces}?search=... for cwd-free public search; uvx hf {models,spaces,datasets} ls|search|info when you need CLI subcommands (note: top-level hf search-repos does not exist — use the per-type subcommands). Read skills/research-orchestrator/references/resource-finder.md for the canonical query patterns.

Workflow

1. date +%Y-%m-%d anchor.
2. Decide axis: if repo_type unset, default to model first, fall back to space for demo discovery.
3. Hit the REST endpoint with sort=downloads&direction=-1&limit=10; parse with jq.
4. For each top candidate, fetch metadata (tags, library, license) via the per-repo endpoint.
5. Optional: download config-only artifacts (uvx hf download <id> --include "*.json" --local-dir /tmp/<name>) to compare model shapes — never download weights.
6. Write findings as JSON to ${workspace_dir}/${artifact_id}.json.
