name: c3 description: | Routes C3 architecture requests and audits existing C3 documentation for consistency. Use when the user asks to "audit architecture", "validate C3", "check C3 docs", "verify docs", "check documentation", "are docs up to date", or when no .c3/ directory exists (routes to onboarding). Routes navigation to c3-navigator agent, changes to c3-orchestrator agent.

C3 Architecture Assistant

REQUIRED: Load References

Before proceeding, use Glob to find and Read these files:

1. **/references/skill-harness.md - Red flags and complexity rules
2. **/references/layer-navigation.md - How to traverse C3 docs

Mode Selection

Mode: Adopt

Route to /onboard skill for the full staged learning loop.

See skills/onboard/SKILL.md for the complete workflow.

Mode: Audit

REQUIRED: Load **/references/audit-checks.md for full procedure.

Checks: Inventory vs code, categorization, reference validity, diagrams, ADR lifecycle, abstraction boundaries, content separation

Content Separation Check (Phase 9):

• Verifies components contain domain logic, refs contain usage patterns
• Uses c3-skill:c3-content-classifier agent for LLM-based analysis
• Detects: missing refs for technologies, integration patterns in components, duplicated patterns

Example:

User: "Check if C3 docs are up to date"

1. Load audit-checks.md
2. Run Phase 1: Gather (list containers, components, ADRs)
3. Run Phase 2-9: Validate each check (including content separation)
4. Output audit report with PASS/FAIL/WARN per check
5. List actionable fixes for any failures
