The content is lean and efficient. Every section serves a purpose—no explanations of what TUS is, what Supabase is, or how HTTP works. It assumes Claude's competence and focuses purely on the specific protocol steps and constraints.

Provides fully executable curl examples for initialization, chunk upload, and resume operations. Headers, base64 encoding, and specific byte sizes are all spelled out concretely. The HALT conditions are explicit and unambiguous.

Five clearly sequenced phases with explicit validation checkpoints (HALT conditions at phases 1, 2, 4), a feedback loop for network failure recovery (HEAD request to resume), exponential backoff retry logic for 409 conflicts, and a final verification phase. This is exemplary workflow design for a multi-step destructive/network operation.

References companion tiles (supabase-mcp-verification, storage-path-validation) at the top with clear paths, keeping the main skill focused on the TUS upload workflow. No deeply nested references; everything is one level deep and clearly signaled.

Lists multiple specific concrete actions: configures TUS resumable upload client, handles Postgres Advisory Lock 409 Conflict, enforces tenant-scoped bucket paths, and specifies the 6MB threshold.

Clearly answers both 'what' (configures TUS resumable upload client with advisory lock handling and tenant-scoped paths) and 'when' (explicit 'Use when...' clause listing five distinct trigger scenarios).

Excellent coverage of natural terms users would say: 'large file uploads', 'resumable uploads', 'TUS protocol', 'unstable networks', 'files larger than 6MB', 'Supabase Storage'. These are terms a developer would naturally use when facing this problem.

Highly distinctive with a very specific niche: TUS protocol + Supabase Storage + Postgres Advisory Locks + 6MB threshold. This combination is unlikely to conflict with any other skill.
