Validating Summaries
Validates summary JSON output against the strict contract defined in
app/core/summary_contract.py.
Summary JSON Contract
See app/core/summary_schema.py for the full Pydantic model.

Validation Scripts
Strict provider-schema validation
Validates raw model output against the complete provider JSON Schema. It requires
every schema field and rejects extra fields or invalid nested structures:
.venv/bin/python .claude/skills/validating-summaries/scripts/validate-summary.py summary.json
Compatibility shaping
Runs the tolerant project mapper used for legacy or partial payloads. Successful
shaping is not evidence that the raw payload satisfied the strict provider schema:
.venv/bin/python .claude/skills/validating-summaries/scripts/validate-with-project.py summary.json
Testing with CLI Runner
Test URL processing and summary generation end-to-end:
.venv/bin/python -m app.cli.summary \
--url https://example.com/article \
--json-path output.json \
--log-level DEBUG
Use the strict script above on output.json when the test is meant to prove that
raw provider output satisfies the generation contract.

Important Notes
get_summary_json_schema() defines the strict provider-output contractvalidate_and_shape_summary() is a tolerant compatibility mapper- JSON repair attempts to fix malformed LLM output (
json_repair library)
- Both English and Russian prompts must be kept in sync
- Database stores verbatim JSON in
summaries.json_payload
- Failed validations are logged with correlation ID for debugging
