Packwright compiles, renders, validates, and captures paired Minecraft Java packs.
Packwright has 7 tools with basic naming (verb_noun pattern) and documented schemas. However, descriptions are minimal (10-50 chars), parameter descriptions lack detail, and output schemas are not visible in the source. Tool names are clear but descriptions fail to explain WHEN to use each tool or what distinguishes similar operations (e.g., render_pack vs capture_pack). No error handling guidance, no parameter constraints beyond enums, and no evidence of idempotency or composition patterns. Schemas are present but sparse.
Captures visual representations of pack content in Minecraft
Compiles a Minecraft resource pack or data pack
Retrieves diagnostic information about a pack project
Retrieves registry data for a specific Minecraft version
Lists all supported Minecraft versions
Renders visual assets from a Minecraft pack
Validates a Minecraft pack against schema and rules
Descriptions are too brief (10-50 chars) and lack context. 'Compiles a Minecraft resource pack or data pack' does not explain WHEN to use compile_pack vs render_pack vs capture_pack, or what the output contains.
Parameter descriptions are missing or minimal. 'projectPath' has a description, but 'packType' enum values ('resource', 'data') lack explanation of what each produces or when to choose one.
Output schemas are not documented in the source. LLMs cannot plan downstream calls or extract required fields (e.g., does compile_pack return a file path, a status, or a full manifest?).

No error handling guidance. Tools that write files (compile_pack, render_pack, capture_pack) may fail due to invalid paths, missing dependencies, or Minecraft version mismatches, but no recovery hints are provided.
Render and capture tools are semantically similar but lack distinguishing descriptions. An LLM cannot determine which to call without trial-and-error or external knowledge of Minecraft pack workflows.
