Run evaluation against acceptance criteria	build

Eval Command

Evaluate implementation against acceptance criteria: $ARGUMENTS

Your Task

Run structured evaluation to verify the implementation meets requirements.

Evaluation Framework

Grader Types

1. Binary Grader - Pass/Fail

   • Does it work? Yes/No
   • Good for: feature completion, bug fixes

2. Scalar Grader - Score 0-100

   • How well does it work?
   • Good for: performance, quality metrics

3. Rubric Grader - Category scores

   • Multiple dimensions evaluated
   • Good for: comprehensive review

Evaluation Process

Step 1: Define Criteria

Acceptance Criteria:
1. [Criterion 1] - [weight]
2. [Criterion 2] - [weight]
3. [Criterion 3] - [weight]

Step 2: Run Tests

For each criterion:

• Execute relevant test
• Collect evidence
• Score result

Step 3: Calculate Score

Final Score = Σ (criterion_score × weight) / total_weight

Step 4: Report

Evaluation Report

Overall: [PASS/FAIL] (Score: X/100)

Criterion Breakdown

Criterion	Score	Weight	Weighted
[Criterion 1]	X/10	30%	X
[Criterion 2]	X/10	40%	X
[Criterion 3]	X/10	30%	X

Evidence

Criterion 1: [Name]

• Test: [what was tested]
• Result: [outcome]
• Evidence: [screenshot, log, output]

Recommendations

[If not passing, what needs to change]

Pass@K Metrics

For non-deterministic evaluations:

• Run K times
• Calculate pass rate
• Report: "Pass@K = X/K"

TIP: Use eval for acceptance testing before marking features complete.
