erp-xpp

erp-xpp is a skill for Claude Code from microsoft/Dataverse-skills. It costs 84 tokens per session (3,399 once invoked), scanned A, original, MIT.

A skill for developing Finance and Operations X++ applications, including models, classes, services, data entities, packages, deployments, database synchronisation, and verification. It includes safety checks for Windows-only tools, target environments, authentication, and deployment status.

In plain words
What is it for?
It is for building, compiling, packaging, deploying, synchronising, and checking Finance and Operations ERP customisations written in X++.
Why use it?
It helps prevent deploying to the wrong environment, overwriting existing ERP code, using mismatched tools, or treating an unfinished deployment as successful.

About the project

microsoft/Dataverse-skills is a collection of skills that lets AI coding agents build, query, deploy, and administer Microsoft Dataverse environments and linked Dynamics 365 Finance and Operations systems. It is for working with Dataverse data models, records, solutions, and Finance and Operations development through natural-language instructions. The catalogue entries are the skills and plugin that operate the Dataverse tools and workflows.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

erp-xpp scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Critical safety rules — read first

  1. Windows only. pac tool xpp install and pac package compile --package-type erp require Windows. Do not invent a Linux/macOS or SDK-based fallback.
  2. Confirm the target before any deploy or DB sync. Show the Dataverse environment URL, obtain explicit confirmation, then run pac org who --environment <url> and verify both the Dataverse URL and linked ERP URL/version.
  3. Never assume Full DB sync. Although standalone pac package db-sync defaults to Full, require the user to choose Full, Module, or Incremental when the request is ambiguous.
  4. Do not call deployment successful until PAC reaches a successful terminal state. Preserve and report the async operation ID on failure.
  5. Do not overwrite existing models or source files. Inspect .erp/xpp.json, descriptors, and target metadata paths before scaffolding or editing.
  6. Pin every runtime surface before ERP verification. PAC and the Dataverse CLI have separate active profiles. Before any dataverse ... --target erp check, require dataverse auth who and dataverse org who --json to match the confirmed Dataverse and linked ERP URLs. Validate ERP MCP according to its transport: direct HTTP must target <erp-url>/mcp; an stdio proxy must receive the base <erp-url> and route effectively to /mcp. Profile selection does not retarget an existing MCP connection.
  7. Treat runtime verification as possible data mutation. After the separate post-deployment opt-in, inspect the X++ implementation, disclose exact test inputs and expected mutations, and obtain confirmation for those inputs and effects. Do not apply a generic test matrix to non-idempotent operations.
  8. All additional validation after an ERP X++ package deployment is opt-in. After pac package deploy --package-type erp, capture PAC's terminal result, then ask whether the user wants any further validation and which checks to run. Do not query the async operation, execute an X++ artifact, query its ERP entity, or test its security unless selected. For runtime validation, confirm exact inputs, success criteria, and failure criteria; never invent values or execute an unapproved failure path. This rule is scoped to ERP X++ package deployment, not Dataverse solution ALM.

PAC CLI is the managed surface for the X++ lifecycle. Do not replace these commands with raw Dataverse APIs, direct calls to the ERP sidecar, LCS upload automation, or hand-written compiler invocations.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
