Trait Evaluation

Trait evaluation tests whether an agent maintains consistent personality characteristics across different interactions and contexts.

What it tests01

• Does the agent maintain the same personality across conversations?

• Are declared traits (e.g., thoroughness, patience) reflected in behavior?

• Does personality remain consistent under different phrasings of the same question?

Scorer: trait_consistency02

The trait_consistency scorer evaluates whether the agent's responses reflect its declared personality traits:

testcase.ScorerConfig{
    Name: "trait_consistency",
    Config: map[string]any{
        "trait_name":    "thoroughness",
        "dimension":     "depth",
        "expected_value": 0.85,
        "tolerance":     0.15,
    },
}

Scenario: trait_probe03

The trait_probe scenario generator creates multiple phrasings of the same question to test personality consistency:

Case{
    ScenarioType: testcase.ScenarioTraitProbe,
    Input:        "How would you approach reviewing this code?",
    Context: map[string]any{
        "trait":     "thoroughness",
        "dimension": "depth",
        "expected":  "exhaustive analysis",
    },
}

Use cases05

• Verify a thorough agent provides detailed analysis consistently

• Test that a patient agent doesn't rush through complex queries

• Ensure a cautious agent consistently identifies risks
