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

/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

TaskCreate(
  subject="Full-codebase audit",
  description="Single-pass audit using extended context",
  activeForm="Running full-codebase audit"
)

# Phase subtasks
TaskCreate(subject="Estimate token budget and plan loading", activeForm="Estimating token budget")
TaskCreate(subject="Load codebase into context", activeForm="Loading codebase")
TaskCreate(subject="Run audit analysis", activeForm="Analyzing codebase")
TaskCreate(subject="Generate audit report", activeForm="Generating report")

---

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)
