# Claude Abap Skills > Skill library for Claude Code — opinionated rules and slash commands for modern ABAP (BTP ABAP Environment, S/4HANA 2023+ ABAP Cloud development model). Assumes the official SAP ABAP MCP Server provides system access. - **Type:** MCP server - **Install:** `agentstack add mcp-matt1as-claude-abap-skills` - **Verified:** Yes — security-reviewed for prompt injection and unsafe behavior - **Seller:** [matt1as](https://agentstack.voostack.com/s/matt1as) - **Installs:** 0 - **Category:** [Integrations](https://agentstack.voostack.com/c/integrations) - **Latest version:** 0.1.0 - **License:** Apache-2.0 - **Upstream author:** [matt1as](https://github.com/matt1as) - **Source:** https://github.com/matt1as/claude-abap-skills ## Install ```sh agentstack add mcp-matt1as-claude-abap-skills ``` Requires the [AgentStack CLI](https://agentstack.voostack.com/docs/cli). Works with Claude Code, Cursor, and any MCP-compatible agent. ## About # claude-abap-skills **The official SAP ABAP MCP Server gives your AI coding agent hands. This library gives it a brain.** Two Claude Code plugins for modern ABAP development — SAP BTP ABAP Environment and S/4HANA on-prem in the ABAP Cloud development model. They live together in this repo but are independent — install either or both. An [`AGENTS.md` template](templates/AGENTS.md) is also provided for use with other AI coding agents (GitHub Copilot, Cursor, …). --- ## What this is A collection of **always-on rules, prompt templates, and slash commands** that turn raw AI-agent output into production-quality modern ABAP, RAP, and ABAP CDS. This is **not** an MCP server. There is no system connector code here. All system access — reading objects, writing source, running ATC, executing ABAP Unit — is assumed to flow through the **official SAP ABAP MCP Server**, distributed as part of the `SAPSE.adt-vscode` VS Code extension. | Component | Role | |--------------------------------------------|------------------------------------------------------------------------------| | `SAPSE.adt-vscode` (official SAP MCP) | **Hands & eyes** — create/activate objects, run ATC, run unit tests, generate RAP services | | `claude-abap-skills` (this repo) | **Brain** — what to write, what to avoid, how to structure RAP, how to review | --- ## The two plugins ### `clean-abap` Universal Clean ABAP rules plus two skills (the rules in `CLAUDE.md` are read by each skill on invocation, not loaded at session start): - **`/clean-abap:review`** — review existing ABAP against the rule set, structured report grouped by severity - **`/clean-abap:refactor`** — refactor to Clean ABAP style in deterministic passes, behavior-preserving, asks before writing back ### `abap-cloud-rap` ABAP Cloud / RAP rules plus three skills (rules read on invocation, as above): - **`/abap-cloud-rap:rap-bo-design`** — design a complete RAP business object end-to-end; drives the SAP ADT MCP `x-ui-service` / `ui-service` / `webapi-service` generators - **`/abap-cloud-rap:atc-remediation`** — walk ATC violations methodically, grouped by category, refuses pseudo-comment suppressions by default - **`/abap-cloud-rap:clean-core-check`** — audit objects for clean core compliance (released APIs, no SAP table reads, no classic constructs, no SAP-standard modifications) Each plugin is **independent** — install either or both. They do not load each other's rules at runtime; the layering is conceptual, not enforced by Claude Code. If you want Clean ABAP rules applied to a Cloud/RAP skill invocation, install both plugins and reference the Clean ABAP plugin's behaviour explicitly. --- ## Supported systems - **SAP BTP ABAP Environment** (Steampunk) - **SAP S/4HANA on-prem**, when developed in the **ABAP Cloud development model** Where the two diverge — released-API surface, allowed `@AbapCatalog` annotations, ATC variants — the skills call it out explicitly and ask which system you are targeting if unclear. ### Not supported - SAP ECC - Classic non-Cloud development model on S/4HANA (any release) - Classic dynpro, logical databases, SAP Query, classic batch input - BAPI-style transactional code where RAP is the modern alternative PRs adding content for unsupported scopes will be closed — see `CONTRIBUTING.md`. --- ## Prerequisites 1. **[Claude Code](https://docs.claude.com/en/docs/claude-code)** installed 2. The **official SAP ABAP MCP Server**, distributed as part of the [`SAPSE.adt-vscode`](https://marketplace.visualstudio.com/items?itemName=SAPSE.adt-vscode) extension, installed and connected to your ABAP system. Enable it under VS Code settings: `adt.mcpServer.enabled: true` 3. A target system: BTP ABAP Environment or S/4HANA on-prem in Cloud development model See `docs/mcp-setup.md` for connection details. --- ## Install Two commands. Both plugins, available in every Claude Code session. ```bash # 1. Register this repo as a plugin source for Claude Code claude plugin marketplace add https://github.com/matt1as/claude-abap-skills # 2. Install both plugins (or just one — they work independently, but pair best together) claude plugin install clean-abap claude plugin install abap-cloud-rap ``` Verify: ```bash claude plugin list ``` You should see both plugins listed. The five skills auto-register and become invokable as `/clean-abap:review`, `/clean-abap:refactor`, `/abap-cloud-rap:rap-bo-design`, `/abap-cloud-rap:atc-remediation`, `/abap-cloud-rap:clean-core-check`. ### Important — `MCP_TIMEOUT` The `rap-bo-design` skill drives the SAP ADT MCP's RAP generators, which routinely take 60–180 s for a multi-entity BO. Claude Code's default MCP tool timeout (~30 s) is shorter. Launch Claude Code with a longer timeout when generation is on the plan: ```bash MCP_TIMEOUT=600000 claude # 10 minutes — plenty of headroom ``` --- ## Workspace bootstrap for other AI coding agents — `AGENTS.md` template The plugins are packaged for Claude Code, but the rule sets they enforce describe ABAP, not any specific agent. AI coding agents that read an `AGENTS.md` workspace bootstrap — GitHub Copilot in VS Code, Cursor, and others — can pick up the same guardrails. [`templates/AGENTS.md`](templates/AGENTS.md) is a drop-in template for an ABAP project workspace. Copy it to the root of your ABAP project, fill in the placeholders (target system, package prefix, GitHub owner), and trim sections that don't apply. It covers: - The same modern-ABAP, released-API, Cloud-development-model guardrails as the plugins - VS Code virtual-workspace quirks, scoped so they don't fire in Eclipse or out-of-process MCP clients - Pointers back into the installed plugins' rule files and slash commands - The `MCP_TIMEOUT` caveat for RAP generators The template follows the convention SAP recommends in its [ADT-for-VS-Code FAQ](https://community.sap.com/t5/technology-blog-posts-by-sap/abap-development-tools-for-visual-studio-code-your-questions-answered/ba-p/14269432) and extends it with the project's full rule set. --- ## Updating ```bash claude plugin marketplace update claude-abap-skills claude plugin update clean-abap claude plugin update abap-cloud-rap ``` --- ## Uninstall ```bash claude plugin uninstall clean-abap claude plugin uninstall abap-cloud-rap claude plugin marketplace remove claude-abap-skills ``` --- ## Repo layout ``` claude-abap-skills/ ├── .claude-plugin/marketplace.json # manifest listing both plugins ├── clean-abap/ # Plugin 1 │ ├── .claude-plugin/plugin.json │ ├── CLAUDE.md # universal Clean ABAP rule set │ ├── review/SKILL.md │ └── refactor/SKILL.md ├── abap-cloud-rap/ # Plugin 2 │ ├── .claude-plugin/plugin.json │ ├── CLAUDE.md # RAP / ABAP Cloud overlay rule set │ ├── rap-bo-design/SKILL.md │ ├── atc-remediation/SKILL.md │ └── clean-core-check/SKILL.md ├── templates/ │ └── AGENTS.md # workspace bootstrap for any AI coding agent ├── docs/mcp-setup.md ├── CLAUDE.md ├── CONTRIBUTING.md ├── LICENSE └── README.md ``` --- ## Known limitations of the official ADT MCP `SAPSE.adt-vscode` 1.0 ships an MCP server tagged as "experimental" in its manifest. It is **creation-focused** — strong for bootstrapping a fresh RAP service end-to-end, weak for everything else. | Capability | Status | |-----------------------------------------------------|--------| | Create new objects (class, CDS, BDEF, service def/binding, access control, …) | ✓ | | Generate complete RAP UI service in one call | ✓ (`x-ui-service` / `ui-service` / `webapi-service`) | | Activate objects | ✓ | | Run ABAP Unit tests | ✓ | | Create / inspect transports | ✓ | | Inspect OData service info of existing bindings | ✓ | | **Read source of an existing object** | ✗ | | **Search the repository** | ✗ | | **Run ATC** | ✗ | Skills affected: `review`, `refactor`, `atc-remediation`, `clean-core-check` currently work on **pasted** source rather than MCP-fetched source. The `rap-bo-design` skill is a perfect fit and uses the generators end-to-end. **Forward-looking.** The MCP is tagged `"experimental"` in the extension manifest, which strongly suggests its capability set will grow over the next releases. When source reads, repository search, or an ATC tool ship, the affected skills will pick them up without changes to their contracts — each `SKILL.md` already says *try the MCP first, fall back to paste*. Treat the current paste-only flows as transitional, not architectural. --- ## Contributing Contributions are very welcome.
