ARC-1

Get compressed dependency context or CDS blast-radius impact for an ABAP / CDS object. Decision rule — pick the action based on the user's question: - "What breaks if I change <CDS view>?" / "Who consumes <I_*>?" / "Impact analysis on <DDLS>" / "Blast radius" → action="impact" - "Understand dependencies before editing <object>" / "What does X depend on?" → action="deps" (default) - "Find all callers of <object>" (cache-warmup required) → action="usages" action="impact" (CDS blast-radius, DDLS only): ALWAYS use this for CDS change-impact questions. Returns upstream AST dependencies plus downstream where-used results classified into RAP-aware buckets: projectionViews, bdefs, serviceDefinitions, serviceBindings, accessControls (DCLS), metadataExtensions (DDLX), abapConsumers, documentation (SKTD), tables, other. Also emits additive sibling-consistency diagnostics (consistencyHints + siblingExtensionAnalysis) when sibling DDLS variants in the same package show asymmetric metadata-extension coverage. DO NOT replicate this with SAPQuery against DDDDLSRC/ACMDCLSRC/DDLXSRC_SRC/SRVDSRC_SRC — those text scans produce noise (non-dependency matches, package group nodes) that this classifier already filters out. Optional includeIndirect=true widens to transitive consumers. Optional siblingCheck=false disables sibling analysis; siblingMaxCandidates controls fan-out (default 4, hard cap 10). action="deps" (default): Returns only the public API contracts (method signatures, interface definitions, type declarations) of all objects that the target depends on — NOT the full source code. The most token-efficient way to understand dependencies. Instead of N separate SAPRead calls returning full source (~200 lines each), returns ONE response with compressed contracts (~15-30 lines each). Typical compression: 7-30x fewer tokens. What deps extracts per dependency: - Classes: CLASS DEFINITION with PUBLIC SECTION only (methods, types, constants). PROTECTED, PRIVATE and IMPLEMENTATION st…

Run diagnostics on ABAP objects and analyze runtime errors. Actions: - "syntax": Syntax check an ABAP object. Requires name + type. Optional: version ("active" or "inactive", defaults to active). Optional: source — when supplied, SAP compiles the given content as if it lived at the object's URI (pre-write dry-run, nothing is written). Omit source to check what is stored. - "unittest": Run ABAP unit tests. Requires name + type. - "atc": Run ATC code quality checks. Requires name + type. Optional: variant. - "cds_testcases": Get SAP-suggested ABAP Unit test cases for a CDS entity (CDS Test Double Framework). Requires name (the CDS entity / DDLS source name; no type needed). Returns one test-method suggestion per testable semantic (whole view, calculated fields, CAST/JOIN/CASE) to scaffold a cl_cds_test_environment unit test. Read-only; SAP_BASIS 8.16+ (ABAP Platform 2025 / S/4HANA 2025) only. - "object_state": Compare active and inactive source versions. Requires name + type. For CLAS, also compares main, definitions, implementations, macros, and testclasses includes (up to 10 parallel reads per class; sequence calls when sweeping many classes). Returns ETags, byte lengths, hashes, and divergence flags. - "quickfix": Get SAP quick fix proposals for a specific source position. Requires name + type + source + line. Optional: column, sourceUri for exact ADT include/source targets. - "apply_quickfix": Apply one quick fix proposal and return text deltas (does not write source). Requires name + type + source + line + proposalUri + proposalUserContent. Optional: column, sourceUri, proposalAffectedObjects. proposalUserContent may be an empty string; pass it through exactly from quickfix. - "dumps": List or read ABAP short dumps (ST22). Without id: lists recent dumps (filter by user, maxResults). With id: returns focused chapter sections by default; set includeFullText=true to include the full formatted dump blob. Optional sections=[kap0,kap3,...] to request specific chapter…

Run local abaplint rules on ABAP and CDS source code. System-aware: auto-selects cloud or on-prem rules based on detected system type. Actions: - "lint": Check source for issues. Returns errors and warnings. Works for ABAP (PROG, CLAS, INTF, FUNC) and CDS views (DDLS) — catches syntax errors, naming conventions, field order, legacy view patterns. - "lint_and_fix": Lint + auto-fix all fixable issues (keyword case, obsolete statements, etc.). Returns fixed source. - "list_rules": List all available rules with current config. No source needed. - "format": Pretty-print ABAP source via SAP's ADT formatter (uses the SAP system's global formatter settings). Requires source. Returns the formatted source. - "get_formatter_settings": Read the SAP system's global PrettyPrinter settings (indentation, keyword style). No params. - "set_formatter_settings": Update the SAP system's global PrettyPrinter settings. Requires indentation (bool) and/or style (keywordUpper|keywordLower|keywordAuto|none). Blocked in read-only mode. For server-side checks (ATC, syntax check, unit tests), use SAPDiagnose instead. Note: lint/lint_and_fix/list_rules run locally; format/*_formatter_settings call the SAP system.

Probe and report SAP system capabilities. Use this BEFORE attempting operations that depend on optional features (abapGit, RAP/CDS, AMDP, HANA, UI5/Fiori, CTS transports, FLP customization). Also handles package (DEVC) lifecycle operations. Actions: - "features": Get cached feature status from last probe (fast, no SAP round-trip). Returns which features are available, their mode (auto/on/off), and when they were last probed. - "probe": Re-probe the SAP system now (runs feature probes, auth checks, and ADT discovery refresh). Use this on first use or if you suspect feature availability has changed. - "cache_stats": Show object cache health and warmup state. - "flp_list_catalogs": List FLP business catalogs. - "flp_list_groups": List FLP groups. - "flp_list_tiles": List tiles in a catalog (requires "catalogId"). - "create_package": Create a package (DEVC) via ADT packages API. - "delete_package": Delete an existing package. - "flp_create_catalog": Create a business catalog (requires "domainId", "title"). - "flp_create_group": Create a group (requires "groupId", "title"). - "flp_create_tile": Create a tile in a catalog (requires "catalogId", "tile"). - "flp_add_tile_to_group": Add a catalog tile to a group (requires "groupId", "catalogId", "tileInstanceId"). - "flp_delete_catalog": Delete a business catalog (requires "catalogId"). Returns JSON with features, each having: id, available (bool), mode, message, and probedAt timestamp. Also returns systemType ("btp" or "onprem") for understanding available capabilities. "available: false" means do NOT attempt operations that depend on it.

Navigate code: find definitions, references (where-used), code completion, and class hierarchy. Use for "go to definition", "where is this used?", "what does this class inherit?", and auto-complete. For references: uses the full scope-based Where-Used API returning detailed results with line numbers, snippets, and package info. Optional objectType filter narrows results to a specific ADT type in slash format (e.g., CLAS/OC, PROG/P). Type+name params are auto-normalized (e.g., type="clas" works). For hierarchy: returns superclass, implemented interfaces, and direct subclasses via SEOMETAREL. You can use type+name instead of uri (e.g., type="CLAS", name="ZCL_ORDER") for a where-used list without needing the full ADT URI. For CDS entities (DDLS), prefer SAPContext(action="impact") — it returns the same where-used data pre-classified into RAP buckets (projection views, BDEFs, SRVDs, access controls, metadata extensions, documentation, ABAP consumers), which answers "what breaks if I change this view" directly without manual bucketing.

Read SAP ABAP objects. Types: PROG, CLAS, INTF, FUNC, FUGR (use expand_includes=true to get all include sources), INCL, DDLS, DCLS (CDS access controls), DDLX (CDS metadata extensions — UI annotations), BDEF, SRVD, SRVB (service bindings — returns structured binding info: OData version, publish status, service definition ref), SKTD (Knowledge Transfer Documents — Markdown documentation attached to ABAP objects like CDS views, BDEFs, classes), TABL (DDIC TABL — covers transparent tables like T000 AND DDIC structures like BAPIRET2; returns CDS-like source. ARC-1 auto-resolves the URL: tries /sap/bc/adt/ddic/tables/ first, falls back to /sap/bc/adt/ddic/structures/. Note: there is no separate STRU type — TABL is the canonical short type for both, mirroring TADIR R3TR TABL and abapGit conventions), VIEW, DOMA (DDIC domains — returns type info, value table, fixed values), DTEL (data elements — returns domain, labels, search help), TRAN (transaction codes — returns description, program, package), TABLE_CONTENTS (simple row preview — no filter or single-column filter; use TABLE_QUERY for multi-column WHERE), TABLE_QUERY (structured multi-column query on DDIC tables and CDS views via the freestyle endpoint — supports AND conditions, column selection; gated by allowDataPreview; use instead of TABLE_CONTENTS when filtering on multiple fields. Note: CDS views require SAP_BASIS 752+ — NW 7.50/7.51 rejects them with "TABLE is invalid here"), DEVC, SOBJ (BOR business objects — returns method catalog or full implementation), SYSTEM, COMPONENTS, MSAG (message classes — returns class metadata + messages array), TEXT_ELEMENTS, VARIANTS. For CLAS: omit include to get the full class source (definition + implementation combined). The include param is optional — use it only to read class-local sections: definitions (local types), implementations (local helper classes), macros, testclasses (ABAP Unit). For CLAS with method param: use method="*" to list all methods with signatures and vis…

Search for ABAP objects. Search by name pattern with wildcards (* for any characters). Returns object type, name, package, description, and ADT URI. Use this to find classes, programs, function modules, tables, etc. 2. TADIR lookup (searchType="tadir_lookup"): Exact cross-package object lookup for one or more names via ADT repository quick search. Use this before create/reset workflows instead of long SAPQuery TADIR IN-lists. Tips: BOR business objects appear as SOBJ type in results. The uri field from results can be used directly with SAPNavigate for references. The objectType field from results can be passed directly to SAPRead/SAPWrite/SAPActivate (ARC-1 auto-normalizes slash suffixes like DDLS/DF, CLAS/OC, PROG/P). Note: Searches object names only (classes, tables, CDS views, etc.) — field/column names are not searchable here. To find fields by name, use SAPRead(type='DDLS', include='elements') for CDS views or SAPQuery against DD03L.

Manage CTS transport requests (SE09/SE10 equivalent). Actions: list (defaults to current user, modifiable transports — both Workbench and Customizing), get (details with tasks and objects), create (K=Workbench, W=Customizing, T=Transport of Copies), release, delete, remove_object (remove an object, keep the request), reassign (change owner), release_recursive (release tasks first, then parent), check (check if a package requires a transport — provide type, name, package), history (find transports referencing an object — provide type, name; read-only, works without SAP_ALLOW_TRANSPORT_WRITES). Transport IDs look like A4HK900123. Status: D=modifiable, R=released.
