Check 2: Database Directory

ls .claude/db/ 2>/dev/null || mkdir -p .claude/db

Check 3: Schema Initialized

sqlite3 .claude/db/marketing.sqlite ".tables" 2>/dev/null | grep -q epics

If epics table is missing, run the PM schema migration:

1. Check if competitive-intel base tables exist (our_products, tags). If not, warn user to initialize competitive-intel first.
2. Check if feature-tracker tables exist (product_features). If not, run feature-tracker schema.sql first.
3. Run schema.sql to add PM tables (epics, requirements, iterators, etc.)
4. Handle ALTER TABLE for existing tables — add columns if missing:

-- Check and add columns to product_features
SELECT COUNT(*) FROM pragma_table_info('product_features') WHERE name = 'epic_id';
-- If 0: ALTER TABLE product_features ADD COLUMN epic_id TEXT REFERENCES epics(id);

SELECT COUNT(*) FROM pragma_table_info('product_features') WHERE name = 'base_version';
-- If 0: ALTER TABLE product_features ADD COLUMN base_version INTEGER NOT NULL DEFAULT 1;

-- Check and add columns to product_feature_tests
SELECT COUNT(*) FROM pragma_table_info('product_feature_tests') WHERE name = 'requirement_id';
-- If 0: ALTER TABLE product_feature_tests ADD COLUMN requirement_id TEXT REFERENCES requirements(id);

SELECT COUNT(*) FROM pragma_table_info('product_feature_tests') WHERE name = 'base_version';
-- If 0: ALTER TABLE product_feature_tests ADD COLUMN base_version INTEGER NOT NULL DEFAULT 1;

Check 4: Schema Version

SELECT version FROM schema_versions WHERE skill = 'pm';

Compare against expected version. If mismatch, run migration steps for the gap.

Output on Success

PM Preflight: OK
  sqlite3: /usr/bin/sqlite3
  database: .claude/db/marketing.sqlite
  schema: pm v1
  tables: epics, requirements, iterators, iterator_values (+ existing)

Rules

1. Hard stop on any failure. No fallbacks. No markdown workarounds.
2. Only skill that runs DDL. All CREATE TABLE and ALTER TABLE happen here.
3. Idempotent. Safe to run multiple times — uses IF NOT EXISTS and column checks.
4. Never deletes data. Only adds tables and columns.
