Guard Fixes
Add input/output validation.
Not available in this release
No new fix is generated or deployed today: fix generation runs after a diagnosis, which is held for the beta, and fix deployment is gated off. This page describes the fix type as designed.
Guard fixes add validation to inputs, outputs, or both.
Use Cases
- Content safety filtering
- JSON format validation
- Input length constraints
- Output length constraints
Configuration
Guard fixes use a guard_type and guard_config structure:
{
"fix_id": "fix-guard-001",
"fix_type": "guard",
"config": {
"guard_type": "content_filter",
"guard_config": {
"blocked_patterns": ["(?i)password", "(?i)secret"]
}
}
}Config Keys
| Key | Type | Description |
|---|---|---|
guard_type | string | One of "content_filter", "format_check", "input_validation", "output_validation" |
guard_config | object | Type-specific guard configuration |
Guard Types
Content Filter
Block content matching regex patterns. Applies to input only:
{
"fix_type": "guard",
"config": {
"guard_type": "content_filter",
"guard_config": {
"blocked_patterns": [
"(?i)password",
"(?i)api[_-]?key",
"\\b\\d{3}-\\d{2}-\\d{4}\\b"
]
}
}
}Format Check
Validate output format (e.g., valid JSON). Applies to output only:
{
"fix_type": "guard",
"config": {
"guard_type": "format_check",
"guard_config": {
"format": "json"
}
}
}Input Validation
Validate input content constraints:
{
"fix_type": "guard",
"config": {
"guard_type": "input_validation",
"guard_config": {
"min_length": 1,
"max_length": 50000
}
}
}Output Validation
Validate output content constraints:
{
"fix_type": "guard",
"config": {
"guard_type": "output_validation",
"guard_config": {
"min_length": 10,
"max_length": 10000
}
}
}Guard Direction
Each guard type applies to a specific direction:
| Guard Type | Input | Output |
|---|---|---|
content_filter | Yes | No |
format_check | No | Yes |
input_validation | Yes | No |
output_validation | No | Yes |
Common Fixes
Block Sensitive Content

}
}Ensure JSON Output
{

}
}
}Limit Input Size
{
"fix_type": "guard",
"config": {
"guard_type": "input_validation",
"guard_config": {
"max_length": 50000
}
}
