Conciseness

The body is dense with product-specific facts Claude cannot know (parameter defaults, "edges is not inherited", variation defect rates), but a few sentences over-explain and could be trimmed, e.g. "The prompt does not need to repeat that the image is a style guide unless the user asks to emphasize a specific detail" and parts of the variation-checking paragraph, matching anchor 4 rather than the every-token-earns-its-place anchor 5.

Actionability

Gives fully executable guidance: exact tool calls with concrete values ("list_presets(mode=\"tileset\", query=...)", "wait_seconds=90", "piece_set=\"15-piece\"", "tile_size=32"), specific error recovery ("When an edit fails twice, generate from the set as reference_asset_id or start fresh with a clearer prompt"), and an explicit recovery action ("execute the supplied warning.recovery tool call"), covering the common cases copy-paste ready.

Workflow Clarity

Sequences are clear (upload/import → asset ID → generate → wait/poll → validate → save) with explicit validation ("Check every variation before using it" plus how: compare left/right and top/bottom edges, paint a test map) and feedback loops for failure ("tileset_unusable" refund and the two-failure retry policy), matching the anchor-5 example with checkpoints and error recovery.

Progressive Disclosure

Sections are well organized (Tools, Recommended Defaults, Reference Workflow, Prompting, Output Handling) with sibling-skill references clearly signaled by name and no nested references, but at roughly 74 lines it exceeds the under-50-line simple-skill threshold and the full parameter table is bulk content that could be split into a reference file as the skill grows, fitting anchor 4 rather than 5.

Specificity

Lists several concrete actions ("generating autotile tilesets through SpriteCook MCP tools", "choosing tile sizes", "using reference/edit/style asset IDs", "saving generated tileset asset IDs"), but the opening "Tileset generation guide for SpriteCook" frames rather than acts and coverage omits prompting, variations, and output handling, so it falls just short of the comprehensive anchor 5.

Completeness

Explicitly answers both "what" (generate autotile tilesets, choose tile sizes, use reference/edit/style asset IDs, save generated asset IDs) and "when" with concrete trigger phrases ("when generating autotile tilesets through SpriteCook MCP tools, choosing tile sizes, using reference/edit/style asset IDs"), which matches the both-present-and-explicit anchor 5.

Trigger Term Quality

Includes natural terms users would say ("tileset", "autotile tilesets", "tile sizes", "SpriteCook"), but common variations such as "tile set", "game tiles", or "tile map" are missing, matching the good-coverage-with-gaps anchor 4 rather than the synonym-complete anchor 5.

Distinctiveness Conflict Risk

It carves a clear niche (SpriteCook tileset generation) and names its companion skill, but its "when" clause spans triggers like using and saving asset IDs that closely related sibling skills (workflow-essentials, upload-assets) also serve, giving minor overlap risk consistent with anchor 4 rather than the minimal-conflict anchor 5.
