X++ has SQL-style statements baked into the language — select, while select, update_recordset, insert_recordset, delete_from — that look like SQL but aren't quite. The differences mostly matter: syntax order, set-based fallback rules, mandatory transactions, and the difference between insert() / update() (which run business logic) vs doInsert() / doUpdate() (which skip it and are usually wrong).
Xpp Data is a community-contributed Claude Code skill in the general-misc sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/xpp-data/ and loads when your prompt matches the skill's trigger.
When to invoke it: Use when writing X++ code that reads from or modifies the D365 F&O database — select statements, while select, joins, set-based operations (update_recordset / insert_recordset / delete_from), the per-record insert/update/delete methods, transaction scoping with ttsBegin / ttsCommit / ttsAbort, and the integrity checks that govern them. Covers the syntax differences from ANSI SQL and the foot-guns (doInsert/doUpdate, set-based fallback, missing forUpdate) that bite developers most often.
The Xpp Data Claude Code skill is built for Claude Code users and developers across all disciplines looking for general-purpose AI assistance. It's part of ClaudSkills (also referred to as Claude Skills or Claude Code Skills) — the open community-curated registry of 196,000+ SKILL.md files for Anthropic's Claude Code agent and the wider Claude ecosystem (Claude API, Claude Agent SDK).

SKILL.md from the source repository to ~/.claude/skills/xpp-data/SKILL.md and restart Claude Code. Both flows are detailed at claudskills.com/install/.SKILL.md file that lives under ~/.claude/skills/<name>/ and tells the Claude Code CLI agent how to perform a specific task (instructions, prompts, allowed tools). Skills are auto-discovered at session start. Xpp Data is one of 67,000+ skills indexed in the open ClaudSkills catalog, classified under the General category.
