axiom

Run a comprehensive backend quality audit across all eight dimensions. Orchestrates scan, critique, harden, distill, verify, and humanize skills, deduplicates findings, and produces a unified report with verdict. Use when assessing overall codebase health. Triggers: 'audit backend', 'full quality check', 'run audit', or /axiom:audit. Do NOT use for targeted checks — use individual skills instead.

Core reference skill defining the backend quality dimension taxonomy, finding format, scoring model, and deterministic check catalog. Not user-invokable — referenced by all axiom skills as the shared foundation.

Apply backend quality dimensions as design constraints during ideation. The design-mode counterpart to axiom:audit — surfaces DIM-1..DIM-8 as questions to ask while shaping a system, not as findings to report after. Pairs with project-specific invariants skills via the pairs-with frontmatter slot. Use when running /exarchos:ideate or any pre-implementation conversation. Triggers: 'apply axiom dimensions to design', 'constrain design space', 'design with quality in mind', or /axiom:design. Do NOT use for review of existing code — use axiom:audit instead.

Bootstrap a project-specific invariants skill that pairs with axiom:design. Interviews the user about the project's domain (one-line characterization, non-obvious commitments, dimension overlap, failure modes, mechanical checks) and emits a SKILL.md plus references files modeled on the design-invariants archetype. Use when starting a new project or formalizing existing architectural invariants. Triggers: 'scaffold invariants skill', 'bootstrap design skill', 'create invariants for this project', or /axiom:scaffold-invariants. Do NOT use to apply invariants — use axiom:design after scaffolding.

Scan for AI writing patterns in markdown, docs, comments, and user-facing strings. Detects 24 cataloged AI-writing tells across content, language, style, communication, and filler categories. Triggers: 'check prose', 'AI writing', 'humanize', or /axiom:humanize. Do NOT use for code quality — use other axiom skills.

Review backend architecture for SOLID violations, coupling issues, and dependency direction problems. Use when evaluating structural design decisions or preparing for refactoring. Triggers: 'review architecture', 'check SOLID', 'critique code', or /axiom:critique. Do NOT use for error handling — use axiom:harden instead.

Strip backend code to its essence by identifying dead code, vestigial patterns, and unnecessary complexity. Use when cleaning up after refactoring or reducing cognitive load. Triggers: 'simplify code', 'find dead code', 'clean up', or /axiom:distill. Do NOT use for error handling — use axiom:harden instead.

Strengthen backend resilience by finding silent catches, missing error context, resource leaks, and operational fragility. Use when hardening error handling or preparing for production deployment. Triggers: 'harden code', 'check error handling', 'resilience review', or /axiom:harden. Do NOT use for dead code — use axiom:distill instead.

Run deterministic pattern checks against backend code. Use when you need mechanical detection of known anti-patterns, code smells, or structural issues. Triggers: 'scan code', 'check patterns', 'run checks', or /axiom:scan. Do NOT use for qualitative architecture review — use axiom:critique instead.

Validate test quality by finding test-production divergence, mock overuse, and schema drift. Use when evaluating test suite health or after discovering a bug that tests missed. Triggers: 'check tests', 'test quality', 'verify contracts', or /axiom:verify. Do NOT use for architecture review — use axiom:critique instead.
