  "message": "Add AI skill to check current repository against upstream APIs (#1460)\n\n* Initial commit for skill to check upstream repo\n\n* Add instructions on using the check-upstream skill\n\n* Add FFI type coverage and implementation pattern to check-upstream skill\n\nDocument the full FFI type pipeline (Rust PyO3 wrapper → Protocol type →\nPython wrapper → ABC base class → exports → example) and catalog which\nupstream datafusion-ffi types are supported, which have been evaluated as\nnot needing direct exposure, and how to check for new gaps.\n\nCo-Authored-By: Claude Opus 4.6 (1M context) \u003cnoreply@anthropic.com\u003e\n\n* Update check-upstream skill to include FFI types as a checkable area\n\nAdd \"ffi types\" to the argument-hint and description so users can invoke\nthe skill with `/check-upstream ffi types`. Also add pipeline verification\nstep to ensure each supported FFI type has the full end-to-end chain\n(PyO3 wrapper, Protocol, Python wrapper with type hints, ABC, exports).\n\nCo-Authored-By: Claude Opus 4.6 (1M context) \u003cnoreply@anthropic.com\u003e\n\n* Move FFI Types section alongside other areas to check\n\nSection 7 (FFI Types) was incorrectly placed after the Output Format and\nImplementation Pattern sections. Move it to sit after Section 6\n(SessionContext Methods), consistent with the other checkable areas.\n\nCo-Authored-By: Claude Opus 4.6 (1M context) \u003cnoreply@anthropic.com\u003e\n\n* Replace static FFI type list with dynamic discovery instruction\n\nThe supported FFI types list would go stale as new types are added.\nReplace it with a grep instruction to discover them at check time,\nkeeping only the \"evaluated and not requiring exposure\" list which\ncaptures rationale not derivable from code.\n\nCo-Authored-By: Claude Opus 4.6 (1M context) \u003cnoreply@anthropic.com\u003e\n\n* Make Python API the source of truth for upstream coverage checks\n\nFunctions exposed in Python (e.g., as aliases of other Rust bindings)\nwere being falsely reported as missing because they lacked a dedicated\n#[pyfunction] in Rust. The user-facing API is the Python layer, so\ncoverage should be measured there.\n\nCo-Authored-By: Claude Opus 4.6 (1M context) \u003cnoreply@anthropic.com\u003e\n\n* Add exclusion list for DataFrame methods already covered by Python API\n\nshow_limit is covered by DataFrame.show() and with_param_values is\ncovered by SessionContext.sql(param_values\u003d...), so neither needs\nseparate exposure.\n\nCo-Authored-By: Claude Opus 4.6 (1M context) \u003cnoreply@anthropic.com\u003e\n\n* Move skills to .ai/skills/ for tool-agnostic discoverability\n\nMoves the canonical skill definitions from .claude/skills/ to .ai/skills/\nand replaces .claude/skills with a symlink, so Claude Code still discovers\nthem while other AI agents can find them in a tool-neutral location.\n\nCo-Authored-By: Claude Opus 4.6 (1M context) \u003cnoreply@anthropic.com\u003e\n\n* Add AGENTS.md for tool-agnostic agent instructions with CLAUDE.md symlink\n\nAGENTS.md points agents to .ai/skills/ for skill discovery. CLAUDE.md\nsymlinks to it so Claude Code picks it up as project instructions.\n\nCo-Authored-By: Claude Opus 4.6 (1M context) \u003cnoreply@anthropic.com\u003e\n\n* Make README upstream coverage section tool-agnostic\n\nRemove Claude Code references and update skill path from .claude/skills/\nto .ai/skills/ to match the new tool-neutral directory structure.\n\nCo-Authored-By: Claude Opus 4.6 (1M context) \u003cnoreply@anthropic.com\u003e\n\n* Add GitHub issue lookup step to check-upstream skill\n\nWhen gaps are identified, search open issues at\napache/datafusion-python before reporting. Existing issues are\nlinked in the report rather than duplicated.\n\nCo-Authored-By: Claude Opus 4.6 (1M context) \u003cnoreply@anthropic.com\u003e\n\n* Require Python test coverage in issues created by check-upstream skill\n\nCo-Authored-By: Claude Opus 4.6 (1M context) \u003cnoreply@anthropic.com\u003e\n\n* Add license text\n\n---------\n\nCo-authored-by: Claude Opus 4.6 (1M context) \u003cnoreply@anthropic.com\u003e",
