audit-full

Full-Codebase Audit

Single-pass whole-project analysis leveraging Opus 5'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 5: Uses complexity: max for extended thinking across entire codebases. 1M context (default and maximum on Opus 5) enables cross-file reasoning that chunked approaches miss. Effort defaults to high; bump to xhigh for one additional cross-file pattern sweep on the hardest codebases.

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.

Effort (CC 2.1.111+): xhigh adds a second pass that re-reads cross-module boundaries specifically looking for patterns the first pass normalized over. The Opus tier has defaulted to high since CC 2.1.154 and reserves xhigh for the hardest codebases. Silently falls back to high on other models; /ork:doctor warns on mismatch.

Switching to Opus (CC 2.1.144+): /model now affects the current session only — pick Opus for this audit without it persisting. Press d in the picker only if you want it as the default for new sessions too.

STEP 0: Verify User Intent with AskUserQuestion

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

Load: Read("${CLAUDE_PLUGIN_ROOT}/skills/audit-full/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

# 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. 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_PLUGIN_ROOT}/skills/audit-full/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_PLUGIN_ROOT}/skills/audit-full/scripts/estimate-tokens.sh /path/to/project

Two tiers — pick by the estimate

audit-full has two execution tiers. The estimate decides which:

Over-budget → run the map-reduce workflow (don't punt, don't silently truncate the load):

# Derive shards from STEP 1 (top-level modules/dirs by size: src, apps/api, apps/web, packages/*).
Workflow({
  "scriptPath": "${CLAUDE_PLUGIN_ROOT}/skills/audit-full/workflows/audit-full-mapreduce.js",
  "args": { "shards": ["<repo-relative dirs>"], "mode": "<full|security|architecture|dependencies>", "effort": "<high|xhigh>" }
})

It preserves cross-file reasoning within each shard and recovers cross-shard edges (taint/auth/dep-direction that span modules) in a dedicated synthesis pass, then runs the same STEP 3.5 adversarial refutation. Its return (merged findings + refutation ledger) feeds STEP 4. The single-context tier remains the default because it's cheaper and loses no boundaries when the repo fits — only reach for map-reduce when it genuinely doesn't.

STEP 2: Load Codebase into Context

Load: Read("${CLAUDE_PLUGIN_ROOT}/skills/audit-full/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_PLUGIN_ROOT}/skills/audit-full/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_PLUGIN_ROOT}/skills/audit-full/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_PLUGIN_ROOT}/skills/audit-full/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 3.5: Adversarial Refutation (effort-gated)

Before the report, a separate blind refuter verifies CRITICAL/HIGH findings — the structural fix for self-preferential bias (a single-context pass grading its own findings anchors on its own reasoning). low/medium skip this step; high runs single advisory refuters; xhigh runs the engine's quorum (3 for CRITICAL, 2 for HIGH).

Load the protocol + audit-full bindings: Read("${CLAUDE_PLUGIN_ROOT}/skills/audit-full/references/adversarial-refutation.md") (which loads the shared engine ${CLAUDE_PLUGIN_ROOT}/shared/rules/adversarial-refutation.md).

These refuters are audit-full's only sub-agent spawns (the producer is single-context), always isolated Agent(...) with no team_name, fed only a neutral claim (category + file:line). Deterministic ground truth is exempt — CVE/CVSS matches, failing build/test, type errors are never refuted; only a reachability claim on top of a CVE is. Cross-file findings the refuter can't reproduce from its narrow slice stay UPHELD (engine §5). Refutation never silently drops a CRITICAL — the ledger (refutation-ledger.json) records survived/killed/downgraded, and removing a CRITICAL/HIGH from the report needs user confirmation.

STEP 4: Generate Report

Load the report template: Read("${CLAUDE_PLUGIN_ROOT}/skills/audit-full/assets/audit-report-template.md").

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

Severity matrix: Read("${CLAUDE_PLUGIN_ROOT}/skills/audit-full/assets/severity-matrix.md") for classification criteria.

Completion Checklist

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

PushNotification on Completion (CC 2.1.110+)

A full-codebase 1M-context audit typically runs 15–60 minutes on medium projects and can exceed that on large ones. After the report file is written and the completion checklist passes, call PushNotification so the finding counts are visible even if the user walked away.

PushNotification(
  message=f"ork:audit-full complete — {SCOPE}: {critical}C/{high}H/{medium}M/{low}L · {report_path}",
  status="proactive"
)

Full rule: Read("${CLAUDE_PLUGIN_ROOT}/skills/chain-patterns/rules/push-notification-on-completion.md").

When NOT to Use

Notes for whole-codebase passes

Oversized reads (CC 2.1.144+): When loading large files, Read returns a [PARTIAL view] truncated first page instead of a hard error if the whole-file read exceeds the token limit. Detect that notice and re-read with explicit offset/limit to page through the rest — a partial read silently omits code an audit must not miss.

When context fills (CC 2.1.141+): Use the rewind menu's "Summarize up to here" to compress earlier turns while keeping recent findings, instead of restarting the audit. Reactive compaction (CC 2.1.142+) sizes the first summarize to the actual overflow, so a wasted second pass mid-turn is now rare.

Running unattended with /goal

Set a completion condition with /goal (CC 2.1.139+) and this skill will keep working across turns until the condition is met. Works in interactive, -p, and Remote Control. The overlay panel shows live elapsed / turns / tokens.

Example completion condition for this skill:

/goal until findings.critical == 0 OR no_new_critical_for_3_turns, or stop after 30 turns

Stops when: zero critical issues remain across 3 consecutive passes, or a structural anti-pattern budget is reached. Compatible with claude.ai Remote Control runs.
