Use the OpenConstructionERP validation engine: rule packs (BOQ quality, DIN 276, NRM, GAEB, MasterFormat, DPGF) that check estimates at import time and on demand. Use when verifying BOQ correctness or writing custom validation rules.

What this skill does
Validation Engine in OpenConstructionERP Philosophy "Validation is a first-class citizen." Every BOQ import (Excel/CSV/GAEB X83/X84) runs the configured rule packs at import time, so violations surface immediately — not when a user is staring at row 452. Built-in rule packs Pack Checks --- --- boqquality required fields, unit consistency, duplicate codes, quantity sanity DIN 276 cost-group codes valid, hierarchy consistent NRM element codes, measurement rules GAEB X83/X84 structure, item references MasterFormat / DPGF classification codes Configure the default set via OEDEFAULTVALIDATIONRULESETS (default ["boqquality"]); run on demand with POST /api/v1/boqs/{id}/validate/. Writing custom rules A rule is: condition + severity + message. Example patterns: Reconciliation rules (the ones that actually catch data problems): qty × unitprice = cost per component line (tolerance ±0.01 or rounding-aware). Σ components = totalresourcecostperposition (markup applied on top). classification non-empty at every tree level. no negative quantities outside documented deduction lines. Where validation plugs in 1. Import gate — importinlinevalidation (env) runs packs during upload. 2. On demand — /boqs/{id}/validate/ returns violations with severity. 3. Continuous — the BOQ quality score updates live as the editor changes lines. Best practices 1. Fail imports on error-severity, warn on warning — never block a user silently. 2. Keep rule messages actionable: name the row, the expected value, the found value. 3. Version rule packs with the standards they encode (DIN 276:2018-12, NRM2, …). 4. Use validation as the QA agent's deterministic backbone (see ai-agent-orchestration).
