# Send Validation Rules Builder to your agent
Hand the extracted package to your coding agent with a concrete install brief instead of figuring it out manually.
## Fast path
- Download the package from Yavira.
- Extract it into a folder your agent can access.
- Paste one of the prompts below and point your agent at the extracted folder.
## Suggested prompts
### New install

```text
I downloaded a skill package from Yavira. Read SKILL.md from the extracted folder and install it by following the included instructions. Tell me what you changed and call out any manual steps you could not complete.
```
### Upgrade existing

```text
I downloaded an updated skill package from Yavira. Read SKILL.md from the extracted folder, compare it with my current installation, and upgrade it while preserving any custom configuration unless the package docs explicitly say otherwise. Summarize what changed and any follow-up checks I should run.

### Problem Statement

Construction data quality challenges:

Inconsistent naming conventions
Invalid cost codes and WBS
Missing or malformed data
Non-compliant BIM elements

### Solution

Rule-based validation engine using RegEx and logic rules to ensure data quality across construction systems.

### Technical Implementation

### Quick Start

# Create validator
validator = ValidationRulesBuilder()

# Add rules
validator.add_required_rule("id_required", "item_id")
validator.use_pattern("wbs_valid", "wbs_code", "wbs_code")
validator.add_range_rule("cost_range", "total_cost", min_value=0, max_value=10000000)
validator.add_enum_rule("status_valid", "status", ["Active", "Completed", "Cancelled"])

# Validate records
records = [
    {"item_id": "001", "wbs_code": "01.02.03", "total_cost": 50000, "status": "Active"},
    {"item_id": "", "wbs_code": "invalid", "total_cost": -100, "status": "Unknown"}
]

results = validator.validate_records(records)
print(f"Valid: {results['valid_records']}/{results['total_records']}")
print(f"Errors: {results['error_count']}, Warnings: {results['warning_count']}")

### 1. Cost Data Validation

cost_validator = ConstructionValidators.cost_item_validator()
results = cost_validator.validate_records(cost_items)

### 2. Schedule Validation

schedule_validator = ConstructionValidators.schedule_activity_validator()
results = schedule_validator.validate_records(activities)

### 3. BIM Element Validation

bim_validator = ConstructionValidators.bim_element_validator()
results = bim_validator.validate_records(elements)
