# 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

| Condition | Mode |
|-----------|------|
| No `.c3/README.md` | **Adopt** - Route to `/onboard` skill |
| Has `.c3/` + "audit" intent | **Audit** - Validate docs |
| Has `.c3/` + question/navigation | Use `c3-skill:c3-navigator` agent |
| Has `.c3/` + change request | Use `c3-skill:c3-orchestrator` agent |

---

## 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.

| Scope | Command |
|-------|---------|
| Full system | `audit C3` |
| Container | `audit container c3-1` |
| ADR | `audit adr adr-YYYYMMDD-slug` |

**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
```
