Lists multiple specific concrete actions: 'Creates tile manifest, validates directory structure, and ensures skill format compliance.' These are clear, actionable capabilities.

Clearly answers both what ('Package a standalone skill into a Tessl tile for versioning, distribution, and evaluation') and when (explicit 'Use when...' clause with multiple trigger scenarios).

Excellent coverage of natural trigger phrases users would say: 'convert to tile', 'package this skill', 'create a tessl tile', 'wrap skill in tile', plus the contextual trigger 'before running evals on a skill not yet in a tile'.

Highly distinctive with domain-specific terminology ('Tessl tile', 'tile manifest', 'skill format compliance') that creates a clear niche unlikely to conflict with other skills.

Content is lean and efficient, providing only necessary information without explaining concepts Claude already knows. Every section serves a clear purpose with no padding or unnecessary context.

Provides fully executable commands and copy-paste ready JSON schemas. The quick start section has concrete bash commands, and the tile.json examples are complete and usable.

Clear numbered sequence with explicit validation checkpoint (lint step). Includes feedback loop guidance: 'If lint fails, see Common Lint Errors below, fix issues, then re-run lint.' Error recovery table provides specific fixes.

Well-organized with clear sections progressing from prerequisites to quick start to detailed schemas. Appropriately references external skill ('creating-eval-scenarios') for next steps. Content length is appropriate for inline presentation.
