Read SAP ABAP objects — exact raw source, a method body, grep output, inactive drafts, revision history, or metadata. For "what does this object do?", explanations, spec work, reviews, or pre-change orientation, prefer SAPContext first (intent-level context before raw source). Types: PROG, CLAS, INTF, FUNC, FUGR (expand_includes=true for all include sources), INCL, DDLS, DCLS, DDLX, BDEF, SRVD, SRVB, SKTD/KTD (KTD aliases SKTD), TABL (covers both transparent tables AND DDIC structures — no separate STRU type), VIEW, DOMA, DTEL, TRAN, TABLE_CONTENTS (single-column filter), TABLE_QUERY (multi-column WHERE via the freestyle endpoint; gated by allowDataPreview; CDS views need SAP_BASIS 752+), DEVC, SOBJ (BOR — method param reads one method), SYSTEM, COMPONENTS, MSAG, TEXT_ELEMENTS, VARIANTS, BSP, BSP_DEPLOY, API_STATE (contract states C0-C4; objectType for non-class), INACTIVE_OBJECTS (no name; pending-activation list), AUTH, FEATURE_TOGGLE, ENHO, VERSIONS, VERSION_SOURCE. AUTH/FEATURE_TOGGLE/ENHO/VERSIONS/VERSION_SOURCE are on-prem only. CLAS: to save tokens, prefer method="*" (all signatures), method="NAME" (one body, ~95% fewer tokens than the full class), or grep over reading the full source. Omit include for the full source, or include=definitions|implementations|macros|testclasses for a local section. Full per-type detail: docs_page SAPRead. Optional grep: case-insensitive regex returning only matching source lines (+context, line numbers); for CLAS, matches are annotated with the owning class/method. Optional version parameter (default "active"): "inactive" reads the user's draft, "auto" the developer view. Active reads note when an inactive draft exists.

Search for ABAP objects, exact object-directory entries, or source code. Modes:

1. Object search (default): name pattern with wildcards (*); returns type, name, package, description, ADT URI.

2. TADIR lookup (searchType="tadir_lookup"): exact cross-package lookup of one or more names (prefer over long SAPQuery TADIR IN-lists). Tips: BOR objects appear as SOBJ; the uri field feeds SAPNavigate, objectType feeds SAPRead/SAPWrite/SAPActivate. Searches object NAMES only — for field names use SAPRead(type='DDLS', include='elements') or SAPQuery on DD03L.

Navigate code: definitions, references (where-used), completion, class hierarchy. references uses the scope-based Where-Used API (line numbers, snippets, package); optional objectType filters by ADT slash type (e.g. CLAS/OC, PROG/P); pass type+name instead of uri. hierarchy returns superclass + interfaces + direct subclasses. For CDS (DDLS), prefer SAPContext(action="impact") — the same where-used pre-classified into RAP buckets, answering "what breaks if I change this view".

Run local abaplint rules on ABAP/CDS source (auto-selects cloud or on-prem rules by system type). Actions:

• "lint": check source (errors+warnings) for ABAP (PROG/CLAS/INTF/FUNC) and CDS (DDLS).

• "lint_and_fix": lint + auto-fix fixable issues (keyword case, obsolete statements); returns fixed source.

• "list_rules": list rules + current config (no source).

• "format": pretty-print via SAP's ADT formatter (needs source).

• "get_formatter_settings" / "set_formatter_settings": read/update the system's global PrettyPrinter (indentation bool, style keywordUpper|keywordLower|keywordAuto|none; set is blocked read-only). lint/lint_and_fix/list_rules run locally; format/*_formatter_settings call SAP. For ATC/syntax/unit tests use SAPDiagnose.

Run diagnostics on ABAP objects and analyze runtime errors. Actions:

• "syntax": syntax-check (name+type; optional version; optional source = pre-write dry-run, nothing written).

• "unittest": run ABAP Unit tests (name+type).

• "atc": run ATC checks (name+type; optional variant).

• "cds_testcases": SAP-suggested ABAP Unit test cases for a CDS entity (name; read-only; SAP_BASIS 8.16+).

• "object_state": compare active and inactive source versions without fetching both (name+type; CLAS compares all includes). Returns ETags, hashes, divergence flags.

• "quickfix": get quick-fix proposals at a position (name+type+source+line; optional column, sourceUri).

• "apply_quickfix": apply one proposal, return text deltas, no write (name+type+source+line+proposalUri+proposalUserContent; pass proposalUserContent through exactly, may be empty).

• "dumps": list/read ST22 short dumps (no id = list; id = read; includeFullText, sections).

• "traces": list/analyze profiler traces (id+analysis: hitlist=hot spots, statements=call tree, dbAccesses=DB stats).

• "trace_start": arm a profiler trace for the NEXT matching execution, then reproduce and read via "traces" (write scope; defaults: next HTTP request, SQL on; optional traceUser/processType/maxExecutions/expiresHours/sqlTrace/…).

• "trace_requests": list armed trace requests. "trace_cancel": cancel one by id (write scope).

• "system_messages": list SM02 messages. "gateway_errors": list /IWFND/ERROR_LOG (on-prem; detailUrl or id+errorType for detail).

• "odata_perf": diagnose why an OData call is slow (url = host-relative path from the Network tab); returns the sap-statistics timing split (DB/ABAP/framework/auth) + a verdict. Read-only; needs allowDataPreview.

• "cds_sql": show the native SQL a CDS view compiles to (name; read-only; may be absent on old releases).

• "sql_trace_state" / "set_sql_trace_state" (sqlOn; needs SAP_ALLOW_WRITES) / "sql_trace_directory": ST05 SQL-trace control. Quickfix workflow: syntax/ATC → quickfix → apply_quickfix → write via SAPWrite. Full action reference: docs_page SAPDiagnose.

Primary tool for understanding ABAP/CDS objects before specs, reviews, explanations, or changes — use instead of SAPRead when the user asks what an object does. Returns intent first (the object KTD when available) then compressed dependency contracts. Use SAPRead after SAPContext for exact source/method bodies/grep/drafts.

Decision rule — pick the action from the user's question:

• "What breaks if I change ?" / "Who consumes <I_*>?" / "Blast radius" → action="impact" (DDLS only).

• "Which includes/appends extend ?" → action="structure", type="TABL".

• "What does do?" / "Explain" / "deps before editing" → action="deps" (default).

• "Find all callers of " (needs cache warmup) → action="usages".

impact (CDS blast-radius): upstream AST deps + downstream where-used, classified into RAP buckets (projectionViews, bdefs, serviceDefinitions, serviceBindings, accessControls, metadataExtensions, abapConsumers, documentation, tables, other) + sibling-consistency hints. Use this instead of text-scanning DDDDLSRC/ACMDCLSRC with SAPQuery (it filters the noise). Optional includeIndirect, siblingCheck, siblingMaxCandidates. deps (default): target KTD + the public API contracts of its dependencies (not full source) — one compact response vs N SAPRead calls (7-30x fewer tokens); SAP standard objects filtered out. For CDS, includes dependency DDL/field catalogs for cl_cds_test_environment. structure (TABL only): the DDIC include/append tree.

Use SAPContext BEFORE editing existing objects. For non-CDS reverse-lookup use SAPNavigate(references); for CDS prefer impact. Full detail: docs_page SAPContext.

Probe and report SAP system capabilities. Use BEFORE operations that depend on optional features (abapGit, RAP/CDS, AMDP, HANA, UI5/Fiori, CTS transports, FLP). Also handles package (DEVC) lifecycle.

Actions:

• "features": cached feature status (fast, no round-trip; id, available, mode, probedAt). "probe": re-probe now (feature probes + auth + discovery refresh). "cache_stats": object cache health.

• "create_package" / "delete_package" / "change_package": DEVC lifecycle via ADT packages API.

• FLP read: flp_list_catalogs, flp_list_groups, flp_list_tiles (catalogId). FLP write: flp_create_catalog, flp_create_group, flp_create_tile, flp_add_tile_to_group, flp_delete_catalog.

• "set_api_state": release/revoke an object's API release contract (objectUri, or name+objectType; apiState defaults RELEASED, contract defaults C1 — C0 for SRVD, C3 for classic views). Write counterpart of SAPRead(type="API_STATE").

Returns features + systemType ("onprem"/"btp"); "available: false" means do NOT attempt dependent operations.

Manage CTS transport requests (SE09/SE10). Actions: list (current user, modifiable), get (tasks + objects), create (always a Workbench (K) request — the package/target sets target & layer, not the request category; optional explicit target), release, delete, remove_object (keep the request), reassign (change owner), release_recursive (tasks then parent), check (does a package need a transport — type, name, package), history (transports referencing an object — type, name; read-only, no write scope needed). IDs look like A4HK900123. Status: D=modifiable, R=released.
