Backend Quality — Foundation Reference

This skill defines the shared foundation for all axiom backend quality skills. It is NOT user-invokable — it exists to be referenced by the specialized skills.

Dimension Taxonomy

Eight canonical quality dimensions: @skills/backend-quality/references/dimensions.md

ID	Name	What it assesses
DIM-1	Topology	Dependency graphs, wiring, ambient state
DIM-2	Observability	Error visibility, logging, failure transparency
DIM-3	Contracts	Schema integrity, API consistency, type safety
DIM-4	Test Fidelity	Test-production divergence, mock quality
DIM-5	Hygiene	Dead code, vestigial patterns, evolutionary leftovers
DIM-6	Architecture	SOLID, coupling, cohesion, dependency direction
DIM-7	Resilience	Resource management, timeouts, failure handling
DIM-8	Prose Quality	AI-writing patterns, documentation authenticity

Finding Format

Standard schema for all skill output: @skills/backend-quality/references/findings-format.md

Scoring Model

Verdict computation and health thresholds: @skills/backend-quality/references/scoring-model.md

Deterministic Checks

Grep patterns and structural checks per dimension: @skills/backend-quality/references/deterministic-checks.md

Pairing Contract
