Before You Start

• tests/fixtures/findings/ — 8 fixture files, one per Phase 1 agent
• schemas/ — 14 JSON schema files; the 8 relevant ones match by base name
• tests/fixtures/CLAUDE.md — documents the 5 known schema violations in current fixtures

Known Violations

Five of eight current fixtures violate their schemas. These are documented and intentional — no runtime schema validation exists in agent.sh. Proceed only if you are intentionally fixing drift:

Fixture	Known Violation
patterns.json	type: 'design' is not in the schema's enum
tooling.json	Missing required purpose field
git-forensics.json	Uses path where schema expects file; missing commit_patterns.example_messages
structure-scout.json	Invalid role strings; extra total_files/total_directories fields

Steps

1. Check which fixtures have required-field violations

for agent in identity commands git-forensics patterns tooling docs-scanner security-scan structure-scout; do
    fixture="tests/fixtures/findings/${agent}.json"
    schema="schemas/${agent}.json"
    if [[ ! -f "$fixture" || ! -f "$schema" ]]; then
        echo "MISSING: $agent"
        continue
    fi
    # Check required fields
    required=$(jq -r '.required[]?' "$schema" 2>/dev/null)
    for field in $required; do
        present=$(jq -e ".${field}" "$fixture" 2>/dev/null && echo yes || echo no)
        if [[ "$present" == "no" ]]; then
            echo "MISSING REQUIRED: $agent.$field"
        fi
    done
done

2. Check for additionalProperties violations

for agent in identity commands git-forensics patterns tooling docs-scanner security-scan structure-scout; do
    fixture="tests/fixtures/findings/${agent}.json"
    schema="schemas/${agent}.json"
    fixture_keys=$(jq -r 'keys[]' "$fixture" 2>/dev/null | sort)
    schema_keys=$(jq -r '.properties | keys[]' "$schema" 2>/dev/null | sort)
    extra=$(comm -23 <(echo "$fixture_keys") <(echo "$schema_keys"))
    if [[ -n "$extra" ]]; then
        echo "EXTRA FIELDS in $agent: $extra"
    fi
done

3. Check enum values

For fields with enum constraints (particularly patterns.json type and structure-scout.json role):

# Check patterns.json type values
jq -r '.patterns[].type' tests/fixtures/findings/patterns.json | sort -u
# Compare against schema enum:
jq -r '.properties.patterns.items.properties.type.enum[]' schemas/patterns.json | sort

4. Fix a fixture

When fixing, use real values — never hand-craft values. Capture from real claude output if possible:

# Option A: Minimal fix — add missing required field
jq '.findings[0] += {"purpose": "example purpose"}' \
    tests/fixtures/findings/tooling.json > /tmp/fixed.json
mv /tmp/fixed.json tests/fixtures/findings/tooling.json

# Option B: Replace invalid enum value
jq '.patterns[].type |= if . == "design" then "architecture" else . end' \
    tests/fixtures/findings/patterns.json > /tmp/fixed.json
mv /tmp/fixed.json tests/fixtures/findings/patterns.json

5. Verify tests still pass after fixing

make test-unit
make test-integration

Fixing a schema violation can break existing tests if a test was asserting on the (incorrect) current value. Update the assertion alongside the fixture.

Verify

# All fixtures are valid JSON
for f in tests/fixtures/findings/*.json; do jq empty "$f" && echo "OK: $f"; done

# Run tests
make test-unit

Common Mistakes

1. Hand-crafting fixture values — the tests/fixtures/CLAUDE.md rule says to capture real claude -p --output-format json output. Hand-crafted fixtures can make tests pass against data that real Claude would never produce.

2. Fixing a fixture without updating dependent tests — some unit tests assert on specific fixture field values. If you fix patterns.json's type enum, find any test that asserts type: 'design' and update it too.
