# Full-Codebase Audit

Single-pass whole-project analysis leveraging Opus 4.6's extended context window. Loads entire codebases (~50K LOC) into context for cross-file vulnerability detection, architecture review, and dependency analysis.

## Quick Start

```bash
/ork:audit-full                          # Full audit (all modes)
/ork:audit-full security                 # Security-focused audit
/ork:audit-full architecture             # Architecture review
/ork:audit-full dependencies             # Dependency audit
```

> **Opus 4.6**: Uses `complexity: max` for extended thinking across entire codebases. 1M context (GA) enables cross-file reasoning that chunked approaches miss.

> **1M Context Required:** If `CLAUDE_CODE_DISABLE_1M_CONTEXT` is set, audit-full cannot perform full-codebase analysis. Check: `echo $CLAUDE_CODE_DISABLE_1M_CONTEXT` — if non-empty, either unset it (`unset CLAUDE_CODE_DISABLE_1M_CONTEXT`) or use `/ork:verify` for chunked analysis instead.

## STEP 0: Verify User Intent with AskUserQuestion

**BEFORE creating tasks**, clarify audit scope using the interactive dialog.

Load: `Read("${CLAUDE_SKILL_DIR}/references/audit-scope-dialog.md")` for the full AskUserQuestion dialog with mode options (Full/Security/Architecture/Dependencies) and scope options (Entire codebase/Specific directory/Changed files).

---

## CRITICAL: Task Management is MANDATORY

```python
# 1. Create main task IMMEDIATELY
TaskCreate(
  subject="Full-codebase audit",
  description="Single-pass audit using extended context",
  activeForm="Running full-codebase audit"
)

# 2. Create subtasks for each phase
TaskCreate(subject="Estimate token budget and plan loading", activeForm="Estimating token budget")  # id=2
TaskCreate(subject="Load codebase into context", activeForm="Loading codebase")                    # id=3
TaskCreate(subject="Run audit analysis", activeForm="Analyzing codebase")                          # id=4
TaskCreate(subject="Generate audit report", activeForm="Generating report")                        # id=5

# 3. Set dependencies for sequential phases
TaskUpdate(taskId="3", addBlockedBy=["2"])  # Loading needs budget estimate
TaskUpdate(taskId="4", addBlockedBy=["3"])  # Analysis needs codebase loaded
TaskUpdate(taskId="5", addBlockedBy=["4"])  # Report needs analysis done

# 4. Before starting each task, verify it's unblocked
task = TaskGet(taskId="2")  # Verify blockedBy is empty

# 5. Update status as you progress
TaskUpdate(taskId="2", status="in_progress")  # When starting
TaskUpdate(taskId="2", status="completed")    # When done — repeat for each subtask
```

## STEP 1: Estimate Token Budget

Before loading files, estimate whether the codebase fits in context.

Load: `Read("${CLAUDE_SKILL_DIR}/references/token-budget-planning.md")` for estimation rules (tokens/line by file type), budget allocation tables, auto-exclusion list, and fallback dialog when codebase exceeds budget.

Run estimation: `bash ${CLAUDE_SKILL_DIR}/scripts/estimate-tokens.sh /path/to/project`

---

## STEP 2: Load Codebase into Context

Load: `Read("${CLAUDE_SKILL_DIR}/references/report-structure.md")` for loading strategy, inclusion patterns by language (TS/JS, Python, Config), and batch reading patterns.

---

## STEP 3: Audit Analysis

With codebase loaded, perform the selected audit mode(s).

### Security Audit

Load: `Read("${CLAUDE_SKILL_DIR}/references/security-audit-guide.md")` for the full checklist.

Key cross-file analysis patterns:
1. **Data flow tracing**: Track user input from entry point → processing → storage
2. **Auth boundary verification**: Ensure all protected routes check auth
3. **Secret detection**: Scan for hardcoded credentials, API keys, tokens
4. **Injection surfaces**: SQL, command, template injection across file boundaries
5. **OWASP Top 10 mapping**: Classify findings by OWASP category

### Architecture Review

Load: `Read("${CLAUDE_SKILL_DIR}/references/architecture-review-guide.md")` for the full guide.

Key analysis patterns:
1. **Dependency direction**: Verify imports flow inward (clean architecture)
2. **Circular dependencies**: Detect import cycles across modules
3. **Layer violations**: Business logic in controllers, DB in routes, etc.
4. **Pattern consistency**: Same problem solved differently across codebase
5. **Coupling analysis**: Count cross-module imports, identify tight coupling

### Dependency Audit

Load: `Read("${CLAUDE_SKILL_DIR}/references/dependency-audit-guide.md")` for the full guide.

Key analysis patterns:
1. **Known CVEs**: Check versions against known vulnerabilities
2. **License compliance**: Identify copyleft licenses in proprietary code
3. **Version currency**: Flag significantly outdated dependencies
4. **Transitive risk**: Identify deep dependency chains
5. **Unused dependencies**: Detect installed but never imported packages

### Progressive Output (CC 2.1.76)

Output findings **incrementally** as each audit mode completes — don't batch until the report:

1. **Security findings first** — show critical/high vulnerabilities immediately, don't wait for architecture review
2. **Architecture findings** — show dependency direction violations, circular deps as they surface
3. **Dependency findings** — show CVE matches, license compliance issues

For multi-mode audits (Full), each mode's findings appear as they complete. This lets users act on critical security findings while architecture analysis is still running.

## STEP 4: Generate Report

Load the report template: `Read("${CLAUDE_SKILL_DIR}/assets/audit-report-template.md")`.

Report structure and severity classification: `Read("${CLAUDE_SKILL_DIR}/references/report-structure.md")` for finding table format, severity breakdown (CRITICAL/HIGH/MEDIUM/LOW with timelines), and architecture diagram conventions.

Severity matrix: `Read("${CLAUDE_SKILL_DIR}/assets/severity-matrix.md")` for classification criteria.

### Completion Checklist

Before finalizing the report, verify with `Read("${CLAUDE_SKILL_DIR}/checklists/audit-completion.md")`.

## When NOT to Use

| Situation | Use Instead |
|-----------|-------------|
| Small targeted check (1-5 files) | Direct Read + analysis |
| CI/CD automated scanning | `security-scanning` skill |
| Multi-agent graded verification | `/ork:verify` |
| Exploring unfamiliar codebase | `/ork:explore` |
| Codebase > 125K LOC (exceeds 1M) | `/ork:verify` (chunked approach) |
