Agent Scorecard Output Quality Framework

Configurable quality evaluation for AI agent outputs. Define criteria, run evaluations, track quality over time. No LLM-as-judge, no API calls, pattern-based automated checks.

Configurable quality evaluation for AI agent outputs. Define criteria, run evaluations, track quality over time.

Agent Scorecard gives you a structured, repeatable way to measure whether your AI agent is producing good output — and whether it's getting better or worse over time. No LLM-as-judge, no API calls, no external dependencies. Everything runs locally with pattern-based automated checks and optional human scoring.

The Problem

You changed your agent's system prompt. Is the output better now? You don't know. You added a new tool. Did response quality degrade? You have a feeling, but no data. Quality management for AI agents is mostly vibes.

Agent Scorecard replaces vibes with numbers.

What It Does

1. Define Quality Dimensions (config_example.json)

• Configure what "quality" means for your use case
• Set dimensions: accuracy, completeness, tone, format compliance, consistency — or your own
• Define rubrics (what does a 1 vs a 5 look like for each dimension?)
• Set weights (accuracy matters more than tone? Give it 2× weight)
• Set pass/fail thresholds per dimension

2. Evaluate (scorecard.py)

• Automated mode: Pattern-based checks run instantly with zero API calls

- Response length analysis (too short? too long?) - Format compliance (expected headers, lists, code blocks present?) - Sycophancy detection ("Great question!" markers) - Filler/hedge word density ("basically", "perhaps", "I think") - Required section verification - Style consistency (sentence length variation)

• Manual mode: Interactive rubric-guided human scoring
• Blended mode: Combine auto scores with human judgment (averaged)
• Aggregate scoring with configurable method (weighted average, minimum, geometric mean)

3. Track (scorecard_track.py)

• Append every evaluation to a JSONL history file
• Filter by agent, task type, time period
• Compute trends per dimension (improving, degrading, stable)
• Linear regression slope for quantified direction
• Sparkline visualisations in terminal

4. Compare (scorecard_track.py)

• Before/after comparison (last N evals vs previous N)
• Per-dimension delta with direction indicators
• Perfect for measuring the impact of config changes

5. Report (scorecard_report.py)

• Single evaluation reports (markdown or JSON)
• History summary reports with tables and sparklines
• Per-dimension breakdowns with rubric reference
• Export to files or stdout

Quick Start

# 1. Configure
cp config_example.json scorecard_config.json
# Edit dimensions, thresholds, and weights for your use case

# 2. Evaluate a response
python3 scorecard.py --config scorecard_config.json --input response.txt

# 3. Evaluate and save to history
python3 scorecard.py --config scorecard_config.json --input response.txt --save history.jsonl

# 4. Manual scoring mode
python3 scorecard.py --config scorecard_config.json --input response.txt --manual --save history.jsonl

# 5. View trends
python3 scorecard_track.py --history history.jsonl --summary

# 6. Compare before/after (last 10 vs previous 10)
python3 scorecard_track.py --history history.jsonl --compare 10

# 7. Generate a report
python3 scorecard_report.py --config scorecard_config.json --history history.jsonl

Programmatic Usage

from scorecard import Scorecard, _load_config

cfg = _load_config("scorecard_config.json")
sc = Scorecard(cfg)

text = open("agent_response.txt").read()
result = sc.evaluate(text, agent="my-agent", task_type="code-review")

print(result.summary())
# Overall: 3.85/5 (PASS)
#   ✓ Accuracy: 4.0/5 (threshold 3, weight 2.0) [auto]
#   ✓ Completeness: 3.5/5 (threshold 3, weight 1.5) [auto]
#   ...

# Save for tracking
import json
with open("history.jsonl", "a") as f:
    f.write(json.dumps(result.to_dict()) + "\
")

Use Cases

• Prompt engineering: Measure whether prompt changes improve output quality
• Model comparison: Same task, different models — which scores higher?
• Agent regression testing: Catch quality degradation before it ships
• Team quality standards: Define shared rubrics for consistent evaluation
• Continuous monitoring: Track quality trends over days/weeks/months
• A/B testing: Quantified before/after comparisons

What's Included

Requirements

• Python 3.8+
• No external dependencies (stdlib only)
• Works on any OS
• Platform-agnostic (works with any AI agent framework)

Configuration

See config_example.json for the complete reference. Key areas:

• DIMENSIONS — Quality dimensions with rubrics, weights, thresholds, and auto-checks
• AUTO_CHECKS — Tuning for each pattern-based check (markers, thresholds, penalties)
• AGGREGATE_METHOD — How to combine dimension scores ("weighted_average", "minimum", "geometric_mean")
• HISTORY_FILE — Where to store evaluation history
• REPORT_OUTPUT_DIR — Where reports are saved

⚠️ Security Note — Config File

Configuration is loaded from a JSON file. This is safe to share — no code execution.

• Config path is validated for existence and size (1MB cap) before loading
• Must be a .json file — raises ValueError if given a non-JSON path
• Keep your config under version control; it defines your quality rubrics and scoring weights
