Commands

waza run

Run an evaluation benchmark from a YAML spec file.

# Run with default mock engine
waza run path/to/eval.yaml --context-dir path/to/fixtures

# Verbose output with results saved
waza run eval.yaml -c ./fixtures -v -o results.json

# Filter to specific tasks
waza run eval.yaml -t "task-name-1" -t "task-name-2"

# Parallel execution
waza run eval.yaml --parallel --workers 4

# Save per-task transcripts
waza run eval.yaml --transcript-dir ./transcripts

waza init

Initialize a new evaluation suite with a compliant directory structure.

# Initialize in current directory
waza init

# Initialize in a named directory
waza init my-eval-suite

Creates: eval.yaml, tasks/ with example task, fixtures/ with example fixture.

waza generate

Generate an eval suite from an existing SKILL.md file.

# Generate eval from SKILL.md
waza generate path/to/SKILL.md

# Specify output directory
waza generate SKILL.md --output-dir ./my-eval

Parses YAML frontmatter (name, description) and creates eval.yaml, starter tasks, and fixtures.

waza compare

Compare results from multiple evaluation runs side by side.

# Compare two result files
waza compare run1.json run2.json

# Compare three or more
waza compare gpt4.json claude.json gemini.json

# JSON output
waza compare run1.json run2.json --format json

Shows per-task score deltas, pass rate differences, and aggregate statistics.

waza dev

Iteratively improve SKILL.md frontmatter compliance with automated scoring.

# Score current skill and suggest improvements
waza dev skills/my-skill

# Target high compliance level
waza dev skills/my-skill --target high

# Auto-apply improvements without prompts
waza dev skills/my-skill --target medium --auto --max-iterations 3

Compliance Levels:

• Low (< 150 chars or no triggers) — Minimal description
• Medium (150+ chars, has triggers) — Basic trigger coverage
• Medium-High (+ anti-triggers) — Routing clarity improved
• High (+ routing markers like INVOKES/FOR SINGLE OPERATIONS) — Full compliance

Scoring Checks:

• Description length (150+ chars required, 1024 max)
• Trigger phrases (USE FOR: patterns)
• Anti-trigger phrases (DO NOT USE FOR: patterns)
• Routing clarity markers (WORKFLOW SKILL, INVOKES:, etc.)
• Token budget (500 soft limit, 5000 hard limit)

Coming Soon: Trigger accuracy tests (#36), --skip-integration (#37), --fast (#38), improvement suggestions engine (#34).

Evaluation Spec Format

name: my-eval
skill: my-skill
version: "1.0"
executor: mock          # or copilot-sdk
tasks:
  - id: task-1
    name: "Describe the task"
    prompt: "Your prompt to the agent"
    expected: "Expected behavior"
    validators:
      - type: code
        config:
          language: go
      - type: text
        config:
          pattern: "expected pattern"

Engines

| Engine | Use | Description | |--------|-----|-------------| | mock | Testing | Returns canned responses for validator development | | copilot-sdk | Production | Executes via Copilot CLI SDK |

Validators

| Validator | What it checks | |-----------|---------------| | code | Code compiles / passes syntax check | | regex | Output matches regex pattern |

Configuration

| Setting | Flag | Default | |---------|------|---------| | Fixtures dir | --context-dir | ./fixtures | | Output file | --output | (none) | | Verbose | --verbose | false | | Parallel | --parallel | false | | Workers | --workers | CPU count | | Transcript dir | --transcript-dir | (none) |

Scoring Quick Reference

Each task produces an EvaluationOutcome with:

| Field | Description | |-------|-------------| | score | 0.0–1.0 normalized score | | pass | Boolean pass/fail | | validator_results | Per-validator details | | duration | Execution time |
