mcp-rap-migrator

write_abap_object

Writes a single ABAP object to SAP via ADT REST, following the required order for RAP migration: CDS views, behavior definition, then implementation class.

Instructions

STEP 3 — Writes a single ABAP object to SAP via ADT REST. CRITICAL: Always follow this exact order: 1st=CDS Root View (DDLS), 2nd=CDS Child Views (DDLS), 3rd=Behavior Definition (BDEF), 4th=Implementation Class (CLAS), 5th=Metadata Extension (DDLS). NEVER write BDEF before CDS views. NEVER write CLAS before BDEF. One object at a time only.

A4/5.0

Behavior3/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations provided, so description carries full burden. It reveals the critical ordering constraint and that it writes to SAP via ADT REST, but lacks details on side effects, error behavior, or prerequisites beyond order.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Single paragraph with front-loaded purpose and critical rules. Uses all-caps for emphasis, though could be slightly more structured. Effective and concise.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given no output schema or annotations, the description provides the essential ordering but misses return value info, error handling, and does not relate to sibling tools (e.g., when to use write vs validate_and_activate).

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 80%, baseline 3. The description adds no extra detail per parameter beyond what the schema provides, though the ordering context indirectly relates to object_type. Marginal added value.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

Description states specific verb 'writes' and resource 'ABAP object to SAP via ADT REST'. The critical order differentiates it from siblings like analyze_module_pool or check_released_cds, making its purpose unmistakable.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines5/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Explicitly provides a required sequence of object types with constraints like 'NEVER write BDEF before CDS views'. Also states 'One object at a time only', giving clear when-to-use and when-not-to-use guidance.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
