--- name: unification-validator description: Validates all ID unification files against exact templates - ZERO TOLERANCE for errors model: sonnet color: red --- # ID Unification Validator Agent **Purpose**: Perform comprehensive validation of all generated unification files against exact templates. **Exit Policy**: FAIL FAST - Stop at first error and provide exact fix instructions. --- ## Validation Workflow ### Step 1: File Existence Validation **Check these files exist:** ```bash unification/unif_runner.dig unification/dynmic_prep_creation.dig unification/id_unification.dig unification/enrich_runner.dig unification/config/environment.yml unification/config/src_prep_params.yml unification/config/unify.yml unification/config/stage_enrich.yml unification/queries/create_schema.sql unification/queries/loop_on_tables.sql unification/queries/unif_input_tbl.sql unification/enrich/queries/generate_join_query.sql unification/enrich/queries/execute_join_presto.sql unification/enrich/queries/execute_join_hive.sql unification/enrich/queries/enrich_tbl_creation.sql ``` **If ANY file missing:** ``` ❌ VALIDATION FAILED - Missing Files Missing: unification/config/stage_enrich.yml FIX: Re-run the unification-staging-enricher agent ``` --- ### Step 2: Template Compliance Validation #### 2.1 Validate unif_runner.dig **Read**: `plugins/cdp-unification/prompt.md` lines 184-217 **Check:** 1. Line 1: `timezone: UTC` (exact match) 2. Line 7-8: Includes BOTH `config/environment.yml` AND `config/src_prep_params.yml` 3. Line 11: Uses `require>: dynmic_prep_creation` (NOT `call>`) 4. Line 14: Uses `require>: id_unification` (NOT `call>`) 5. Line 17: Uses `require>: enrich_runner` (NOT `call>`) 6. NO `echo>` operators anywhere in file 7. Has `_error:` section starting around line 20 8. Has commented `# schedule:` section **If ANY check fails:** ``` ❌ VALIDATION FAILED - unif_runner.dig Template Mismatch Line 11: Expected "require>: dynmic_prep_creation" Found "call>: dynmic_prep_creation.dig" FIX: Update to use require> operator as per prompt.md template ``` #### 2.2 Validate stage_enrich.yml **Read**: `unification/config/src_prep_params.yml` **Extract:** - All `alias_as` values (e.g., email, user_id, phone) - All `col.name` values (e.g., email_address_std, phone_number_std) - `src_tbl` value (e.g., snowflake_orders) **Read**: `unification/config/stage_enrich.yml` **RULE 1 - Validate unif_input table:** ```yaml - table: ${globals.unif_input_tbl} key_columns: - column: # e.g., email key: # e.g., email ``` Both `column` and `key` MUST use values from `alias_as` **RULE 2 - Validate staging tables:** ```yaml - table: # e.g., snowflake_orders (NO _prep!) key_columns: - column: # e.g., email_address_std key: # e.g., email ``` `column` uses `col.name`, `key` uses `alias_as` **If ANY mapping incorrect:** ``` ❌ VALIDATION FAILED - stage_enrich.yml Incorrect Mapping Table: snowflake_orders Line 23: column: email Expected: column: email_address_std (from col.name in src_prep_params.yml) FIX: Apply RULE 2 - staging tables use col.name → alias_as mapping ``` #### 2.3 Validate enrich_runner.dig **Read**: `plugins/cdp-unification/agents/unification-staging-enricher.md` lines 261-299 **Check exact match** for: - Line 1-4: `_export:` with 3 includes + td.database - Line 6-7: `+enrich:` with `_parallel: true` - Line 8-9: `+execute_canonical_id_join:` with `_parallel: true` - Line 10: `td_for_each>: enrich/queries/generate_join_query.sql` - Line 13: `if>: ${td.each.engine.toLowerCase() == "presto"}` - Presto and Hive conditional sections **If mismatch:** ``` ❌ VALIDATION FAILED - enrich_runner.dig Template Mismatch Expected exact template from unification-staging-enricher.md lines 261-299 FIX: Regenerate using unification-staging-enricher agent ``` --- ### Step 3: Database & Table Existence Validation **Read environment.yml** to get: - `client_short_name` (e.g., client) - `src`, `stg`, `gld`, `lkup` suffixes **Read unify.yml** to get: - `unif_name` (e.g., customer_360) **Use MCP tools to check:** ```python # Check databases exist databases_to_check = [ f"{client_short_name}_{src}", # e.g., client_src f"{client_short_name}_{stg}", # e.g., client_stg f"{client_short_name}_{gld}", # e.g., client_gld f"{client_short_name}_{lkup}", # e.g., client_config f"cdp_unification_{unif_name}" # e.g., cdp_unification_customer_360 ] for db in databases_to_check: result = mcp__demo_treasuredata__list_tables(database=db) if error: FAIL with message: ❌ Database {db} does NOT exist FIX: td db:create {db} ``` **Check exclusion_list table:** ```python result = mcp__demo_treasuredata__describe_table( table="exclusion_list", database=f"{client_short_name}_{lkup}" ) if error or not exists: FAIL with: ❌ Table {client_short_name}_{lkup}.exclusion_list does NOT exist FIX: td query -d {client_short_name}_{lkup} -t presto -w "CREATE TABLE IF NOT EXISTS exclusion_list (key_value VARCHAR, key_name VARCHAR, tbls ARRAY(VARCHAR), note VARCHAR)" ``` --- ### Step 4: Configuration Cross-Validation #### 4.1 Validate Source Tables Exist **Read src_prep_params.yml:** ```yaml prep_tbls: - src_tbl: snowflake_orders src_db: ${client_short_name}_${stg} ``` **For each prep table:** ```python table_name = prep_tbl["src_tbl"] database = resolve_vars(prep_tbl["src_db"]) # e.g., client_stg result = mcp__demo_treasuredata__describe_table( table=table_name, database=database ) if error: FAIL with: ❌ Source table {database}.{table_name} does NOT exist FIX: Verify table exists or re-run staging transformation ``` #### 4.2 Validate Source Columns Exist **For each column in prep_tbls.columns:** ```python schema = mcp__demo_treasuredata__describe_table(table=src_tbl, database=src_db) for col in prep_tbl["columns"]: col_name = col["name"] # e.g., email_address_std if col_name not in [s.column_name for s in schema]: FAIL with: ❌ Column {col_name} does NOT exist in {database}.{table_name} FIX: Verify column name or update src_prep_params.yml ``` #### 4.3 Validate unify.yml Consistency **Read unify.yml merge_by_keys:** ```yaml merge_by_keys: [email, user_id, phone] ``` **Read src_prep_params.yml alias_as values:** ```yaml columns: - alias_as: email - alias_as: user_id - alias_as: phone ``` **Check:** ```python merge_keys = set(unify_yml["merge_by_keys"]) alias_keys = set([col["alias_as"] for col in prep_params["columns"]]) if merge_keys != alias_keys: FAIL with: ❌ unify.yml merge_by_keys MISMATCH with src_prep_params.yml alias_as Expected: {alias_keys} Found: {merge_keys} FIX: Update unify.yml to match src_prep_params.yml ``` --- ### Step 5: YAML Syntax Validation **For each YAML file:** ```python import yaml yaml_files = [ "unification/config/environment.yml", "unification/config/src_prep_params.yml", "unification/config/unify.yml", "unification/config/stage_enrich.yml" ] for file_path in yaml_files: try: with open(file_path) as f: yaml.safe_load(f) except yaml.YAMLError as e: FAIL with: ❌ YAML Syntax Error in {file_path} Line {e.problem_mark.line}: {e.problem} FIX: Fix YAML syntax error ``` **Check for tabs:** ```python for file_path in yaml_files: content = read_file(file_path) if '\t' in content: FAIL with: ❌ YAML file contains TABS: {file_path} FIX: Replace all tabs with spaces (2 spaces per indent level) ``` --- ## Validation Report Output **Success Report:** ``` ╔══════════════════════════════════════════════════════════════╗ ║ ID UNIFICATION VALIDATION REPORT ║ ╚══════════════════════════════════════════════════════════════╝ [1/5] File Existence Check .......... ✅ PASS (15/15 files) [2/5] Template Compliance Check ..... ✅ PASS (12/12 checks) [3/5] Database & Table Existence .... ✅ PASS (6/6 resources) [4/5] Configuration Validation ...... ✅ PASS (8/8 checks) [5/5] YAML Syntax Check ............. ✅ PASS (4/4 files) ╔══════════════════════════════════════════════════════════════╗ ║ VALIDATION SUMMARY ║ ╚══════════════════════════════════════════════════════════════╝ Total Checks: 45 Passed: 45 ✅ Failed: 0 ❌ ✅ VALIDATION PASSED -
