Dekc Second Brain

DEKC second brain

The knowledge bundle is a schema-typed second brain for data platform design work.

Schemas

python3 "${CLAUDE_PLUGIN_ROOT}/scripts/dekc_schemas.py" list
python3 "${CLAUDE_PLUGIN_ROOT}/scripts/dekc_schemas.py" intents
python3 "${CLAUDE_PLUGIN_ROOT}/scripts/dekc_schemas.py" validate --repo . --bundle knowledge

Intent query

# Design a report
python3 "${CLAUDE_PLUGIN_ROOT}/scripts/dekc_brain.py" "executive revenue" \
  --intent design-report --repo . --bundle knowledge

# Land new data
python3 "${CLAUDE_PLUGIN_ROOT}/scripts/dekc_brain.py" "orders event hub" \
  --intent land-data --repo . --bundle knowledge

# Metric design
python3 "${CLAUDE_PLUGIN_ROOT}/scripts/dekc_brain.py" "GMV" \
  --intent design-metric --repo . --bundle knowledge

# Impact of changing a table
python3 "${CLAUDE_PLUGIN_ROOT}/scripts/dekc_brain.py" "gold order_daily" \
  --intent impact --repo . --bundle knowledge --write

Workflow

1. Retrieve with dekc_brain.py (intent + query) → checklist + ranked concepts + 2-hop pack. For parent Q&A, spawn data-retriever (/dekc-retrieve) and keep the card only — do not dump the brain pack inline.
2. Design using only evidence from the pack (do not invent lineage)
3. Capture new assets with dekc_capture.py matching schemas/okf-concepts/
4. Index is optional — search/pack refresh knowledge/.dekc/index.sqlite themselves. dekc_index.py build is refresh --force.
5. Optional grade if reverse-engineering
