name: ingest-l0 description: "L0 bootstrap of the abap_wiki knowledge base: creates stubs for all custom objects from the TADIR. Use this skill to initialize the repo from scratch or to ingest a new TADIR export. Deterministic operations (no LLM sub-agent), idempotent."

Ingest L0 - stub bootstrap from TADIR

Creates (or updates) the L0 stub for every custom object in the TADIR. Everything is deterministic: no sub-agents, parallelism via devclass partitioning. State lives in state/abap_wiki.db (see core/docs/01-pipeline-l0-l1.md).

When to use it

• First-time initialization of the repo (empty DB).
• Arrival of a new export raw/tadir/TADIR_Z_<YYYYMMDD>.XLSX.

Procedure

Shortcut: python core/src/tools/pipeline.py l0-run runs steps 1-6 as a single deterministic command (newest TADIR in raw/tadir/ or --file). The step-by-step procedure below remains the reference for diagnostics.

All commands must be run from the repo root with the venv active.

1. Initialize the schema (idempotent):

   python core/src/tools/pipeline.py init-db
   

2. Import the TADIR (dtype=str, excludes objects already removed from the L1 queue):

   python core/src/tools/pipeline.py import-tadir --file raw/tadir/<most recent TADIR>.XLSX
   

3. Resolve sources (unique in-memory index, deterministic hash):

   python core/src/tools/pipeline.py resolve-sources
   

4. Create L0 stubs (all, or by devclass partition in parallel across multiple sessions):

   python core/src/tools/pipeline.py ingest-l0            # all
   python core/src/tools/pipeline.py ingest-l0 --partition ZPACKAGE   # one package
   

   Idempotent: re-running on an already-processed package is a no-op.
5. Enqueue L1 (only analyzable types with available source):

   python core/src/tools/pipeline.py enqueue-l1
   

6. Verify and commit:

   python core/src/tools/pipeline.py progress
   python core/src/tools/pipeline.py export-excel
   python core/src/tools/pipeline.py git-commit --message "ingest L0: <export>"
   

Rules

• Never modify raw/ (only the user stages it when updating the export).
• Indexes (abap_wiki/_packages/, abap_wiki/index.md) are regenerated from queries: do not edit them manually.
• If unknown TADIR types appear they are mapped to tadir-<x> and listed in output/reports/unknown-tadir-types.md (non-blocking).
