# 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

```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 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

```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. 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:

| Estimate vs budget | Tier | Path |
|--------------------|------|------|
| **Fits** (~≤125K LOC / ≤1M tokens) | **Single-context** (default — the skill's edge: whole-codebase cross-file reasoning in one window) | continue to STEP 2 |
| **Exceeds** budget | **Map-reduce** (scale tier — shard → per-shard audit → cross-shard boundary synthesis → refute) | invoke the workflow below; STEP 2–3.5 run *inside* it |

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

```python
# 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.

```python
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

| 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) | **stay here** — STEP 1 routes to the map-reduce tier (`workflows/audit-full-mapreduce.js`); `/ork:verify` only if you want multi-agent *graded* verification instead of an audit |

---

## 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.
