Calculation Report Skill

Pipeline

calculation.yaml → generate-calc-report.py → report.html (default) / report.md

Usage

# Generate HTML (default)
uv run --no-project python scripts/reporting/generate-calc-report.py <input.yaml>

# Generate Markdown with LaTeX math
uv run --no-project python scripts/reporting/generate-calc-report.py <input.yaml> --format md

# Specify output path
uv run --no-project python scripts/reporting/generate-calc-report.py <input.yaml> --output path/to/report.html

YAML Structure (Required Sections)

• metadata: title, doc_id, revision, date, author, status (draft/reviewed/approved)
• inputs: list of {name, symbol, value, unit} with optional source/notes
• methodology: description, standard, equations [{id, name, latex, description}]
• outputs: list of {name, symbol, value, unit} with optional pass_fail/limit
• assumptions: list of strings
• references: list of strings

Optional Sections

• charts: interactive Chart.js charts (line, bar, scatter, log_log)
• data_tables: tabular data with column headers and units
• change_log: revision history in metadata

Examples (13 calc reports)

• examples/reporting/dividend-yield-forecast.yaml — Gordon growth model

Schema Validation Gate (mandatory before report generation)

Full schema at config/reporting/calculation-report-schema.yaml.

Validate EVERY YAML before generating the report:

uv run --no-project python -c "
import yaml
with open('config/reporting/calculation-report-schema.yaml') as f:
    schema = yaml.safe_load(f)
with open('<your-calc>.yaml') as f:
    report = yaml.safe_load(f)
# Required sections
for s in ['metadata', 'inputs', 'methodology', 'outputs', 'assumptions', 'references']:
    assert s in report, f'Missing: {s}'
# Metadata fields
for f in ['title', 'doc_id', 'revision', 'date', 'author', 'status']:
    assert f in report['metadata'], f'Missing metadata.{f}'
# Standard traceability
assert 'standard' in report['methodology'], 'Missing methodology.standard'
assert 'equations' in report['methodology'], 'Missing methodology.equations'
for eq in report['methodology']['equations']:
    assert 'name' in eq and 'latex' in eq, f'Equation missing name or latex'
print('PASS')
"

Compliance Audit

Run periodically to catch missing reports across all implementations:

# List all calc report YAMLs and validate each
for f in examples/reporting/*.yaml; do
  echo -n "$f: "
  uv run --no-project python -c "import yaml; d=yaml.safe_load(open('$f')); [d[s] for s in ['metadata','inputs','methodology','outputs','assumptions','references']]; print('PASS')" 2>&1 || echo "FAIL"
done

Tests

uv run --no-project --with PyYAML --with pytest python -m pytest tests/reporting/test_generate_calc_report.py -v
