Implement copyFiles API for huggingface.js bucket support
Session from pi-sessions on Hugging Face by julien-c · CC-BY-4.0 · condensed by Coders Talk
Port the `copy_files`/bucket-copy feature from the huggingface_hub Python commit into the huggingface.js hub package, including CLI-style `hf://` handle parsing and unit tests.
- +9mPrompt · +9mCheck commit d82a7f7d... in huggingface_hub and implement the same feature (bucket copy) in this codebase
- +9mAgent did · +9mReviewed the huggingface_hub commit's diffs (hf_api.py, _buckets.py, cli/buckets.py, tests), studied existing hub package patterns (commit.ts, paths-info.ts, list-files.ts, download-file.ts), then wrote a first draft of copy-files.ts implementing parseHfCopyHandle and copyFiles.
- +31mAgent did · +31mExported copy-files from lib/index.ts, ran tsc and fixed type errors (const reassignment, missing repoType property, unused variable) until copy-files.ts compiled cleanly.
- +36mPrompt · +36mGit commit it, no need to read any skill, just do a simple git commit
- +39mAgent did · +39mCommitted the new copy-files.ts and index.ts changes, then on request committed IDE-formatted code and removed unused RepoId/toRepoId imports as separate commits.
- +51mPrompt · +51mStart a very simple .spec.ts file, testing only parseHfCopyHandle with 2 or 3 simple test cases
- +52mFail · +52mInitial tests failed: repoType returned 'datasets' instead of singular 'dataset', and bucket handle parsing only captured the first path segment instead of namespace/bucket-name.
- +55mAgent did · +55mFixed the repoType singularization and the bucket path slicing logic; all 3 tests passed, and the fixes plus spec file were committed.
- +1h 2mIntervention · +1h 2mRepeated the same rename request (ValueError to CopyHandleError) multiple times over ~1.5 hours with no useful response, then gave up on the model after it failed one of two edits and asked a generic clarifying question instead of just finishing the rename.Why: I asked the same simple rename three times and it kept stalling or giving vague follow-up questions instead of just doing the edit, so I lost patience and decided to try a different model.
- +1h 27mOutcome · +1h 27mSession ends with the ValueError→CopyHandleError rename still incomplete, developer repeating the request unanswered.
Next time I'd give the exact rename edit up front, including both call sites, instead of asking for it piecemeal so the agent doesn't half-apply it. The intervention that actually helped was writing the small spec.ts myself as a prompt - it immediately caught two real parsing bugs (repoType pluralization and bucket path slicing) that the agent then fixed correctly. The session fell apart at the end when a trivial rename got stuck in a loop and the model started asking clarifying questions instead of just doing the edit.
