skill-audit

> Host: Codex CLI — This skill was designed for Claude Code and adapted for Codex.

> Cross-reference commands use installed skill names in Codex rather than /octo:* slash commands.

> Use the active Codex shell and subagent tools. Do not claim a provider, model, or host subagent is available until the current session exposes it.

> For host tool equivalents, see skills/blocks/codex-host-adapter.md.

Systematic Audit Process

Load skills/blocks/engineering-method-selection.md from the installed plugin

and apply only the methods relevant to this task. Preserve this entry point's

execution contract and output format. Read referenced skills as instructions;

do not invoke the current command recursively or add provider calls from a seat.

Overview

Comprehensive, methodical auditing to find issues, inconsistencies, and broken features across a codebase.

Core principle: Define scope → Create checklist → Execute systematically → Report findings → Prioritize fixes.

For architecture simplification, load

skills/blocks/architecture-simplification.md. Pin the revision, inspect recent

churn and representative callers, then apply the deletion test. Do not recommend

removing a small wrapper when it centralizes a security, cleanup, precedence, or

failure invariant. A simplify verdict needs source evidence, a concrete caller,

and migration and rollback steps.

When to Use

Use this skill when user wants to:

• Audit entire application for issues
• Find all instances of a problem pattern
• Check for broken features systematically
• Comprehensive quality verification
• Identify inconsistencies across codebase

Do NOT use for:

• Security vulnerability scanning (use skill-security-audit)
• Code quality review (use skill-code-review)
• Single file searches (use Grep/Glob directly)
• Performance profiling

The Process

Phase 1: Scope Definition

Step 1: Understand Audit Objectives

**Audit Objectives:**

What to audit: [app features, code patterns, specific issues]
Why auditing: [what prompted this, what problem are we solving]
Scope: [entire app, specific module, particular feature set]
Depth: [surface-level or deep inspection]

Step 2: Define Audit Criteria

Use AskUserQuestion if needed:

**Audit Focus:**

Which aspects should I audit?
1. Functional - Do features work as expected?
2. Consistency - Are patterns applied uniformly?
3. Completeness - Are implementations finished?
4. Quality - Is code maintainable?
5. User-facing - Does UI/UX work correctly?
6. Integration - Do components work together?

Step 3: Create Audit Plan

**Audit Plan**

**Areas to Cover:**
1. [Area 1: e.g., All form submissions]
2. [Area 2: e.g., All API endpoints]
3. [Area 3: e.g., All button states]
4. [Area 4: e.g., All error handling]

**Methodology:**
- [ ] Identify all instances
- [ ] Test each systematically
- [ ] Document findings
- [ ] Categorize by severity
- [ ] Propose fixes

**Estimated Coverage:** [X components, Y files, Z features]

Phase 2: Discovery

Step 1: Identify Audit Targets

Use Glob and Grep to find all relevant code:

**Finding Audit Targets:**

Searching for: [pattern/feature]
Method: [glob pattern or grep query]

**Found:**
1. [File 1:line]
2. [File 2:line]
3. [File 3:line]
...
N. [File N:line]

Total instances: [N]

Step 2: Create Audit Checklist

**Audit Checklist:**

- [ ] Item 1: [component/feature to check]
  - Location: [file:line]
  - Expected: [what should happen]
  - Test: [how to verify]

- [ ] Item 2: [component/feature to check]
  - Location: [file:line]
  - Expected: [what should happen]
  - Test: [how to verify]

...

Total items to audit: [N]

Use task plan tool to track audit progress.

Phase 3: Systematic Execution

Step 1: Execute Audit Checklist

For each item:

**Auditing Item [N]/[Total]: [Description]**

**Location:** [file:line]

**Check 1: [Test name]**
- Expected: [what should happen]
- Method: [how to test - code review, runtime check, etc.]
- Result: ✓ Pass / ❌ Fail
- Evidence: [what you observed]

**Check 2: [Test name]**
- Expected: [what should happen]
- Method: [how to test]
- Result: ✓ Pass / ❌ Fail
- Evidence: [what you observed]

**Overall Status:** ✓ Pass / ⚠️ Issues Found / ❌ Broken

**Issues:**
[If any issues, list them here]

Step 2: Track Progress

Audit Progress:
✓ [1/50] User login form
✓ [2/50] Password reset form
⚠️ [3/50] Registration form (issues found)
❌ [4/50] Contact form (broken)
⚙️ [5/50] Newsletter signup (in progress)
- [6/50] Survey form
...

Phase 4: Analysis & Reporting

Step 1: Categorize Findings

**Audit Findings Summary**

**Critical Issues (Broken Functionality):**
1. [Issue 1]
   - Location: [file:line]
   - Impact: [what's broken]
   - Severity: Critical

2. [Issue 2]
   - Location: [file:line]
   - Impact: [what's broken]
   - Severity: Critical

**Major Issues (Degraded Functionality):**
1. [Issue 1]
   - Location: [file:line]
   - Impact: [what's wrong]
   - Severity: Major

**Minor Issues (Inconsistencies/Polish):**
1. [Issue 1]
   - Location: [file:line]
   - Impact: [what's inconsistent]
   - Severity: Minor

**Passed Checks:**
- [N] items fully functional
- [List if relevant]

Step 2: Provide Statistics

**Audit Statistics**

Total Items Audited: [N]
✓ Passed: [N] ([X%])
⚠️ Issues Found: [N] ([X%])
❌ Broken: [N] ([X%])

**By Category:**
- Critical: [N]
- Major: [N]
- Minor: [N]

**Coverage:**
- Files reviewed: [N]
- Components tested: [N]
- Code paths verified: [N]

Phase 5: Remediation Plan

Step 1: Prioritize Issues

**Recommended Fix Priority:**

**Phase 1: Critical Fixes (Do First)**
1. [Issue - file:line]
   - Why critical: [reason]
   - Estimated effort: [time]

2. [Issue - file:line]
   - Why critical: [reason]
   - Estimated effort: [time]

**Phase 2: Major Fixes (Do Next)**
1. [Issue - file:line]
   - Impact: [description]
   - Estimated effort: [time]

**Phase 3: Minor Fixes (Nice to Have)**
1. [Issue - file:line]
   - Impact: [description]
   - Estimated effort: [time]

**Total Estimated Effort:** [sum of all fixes]

Step 2: Offer to Execute Fixes

**Next Steps:**

I found [N] issues during the audit.

Would you like me to:
1. Fix all critical issues now (estimated [time])
2. Fix issues one category at a time (critical → major → minor)
3. Let you review findings first, then decide what to fix
4. Create detailed tickets/todos for each issue

What's your preference?

Common Patterns

Pattern 1: Audit Entire App for Broken Features

User: "Create a process to audit and check the entire app for things that might be broken"

Implementation:

**Phase 1: Scope**
- Audit all user-facing features
- Check for runtime errors
- Verify expected behavior

**Phase 2: Discovery**
- List all features (from routes, components, docs)
- Create comprehensive checklist

**Phase 3: Execute**
- Test each feature systematically
- Document working vs broken

**Phase 4: Report**
- Critical: Features that crash
- Major: Features that work incorrectly
- Minor: Features with UX issues

**Phase 5: Fix**
- Prioritized remediation plan

Pattern 2: Audit for Specific Pattern

User: "Find all instances of direct DOM manipulation and check if they should use React state"

Implementation:

**Phase 1: Scope**
- Audit: Direct DOM manipulation patterns
- Goal: Identify React anti-patterns

**Phase 2: Discovery**
- Grep for: document.querySelector, getElementById, etc.
- Found: [N] instances

**Phase 3: Execute**
- Check each instance:
  - Is there a good reason for direct DOM?
  - Should it use React state instead?
  - Is it causing bugs?

**Phase 4: Report**
- List instances that should migrate to React
- List instances that are fine as-is

**Phase 5: Fix**
- Refactor problematic instances

Pattern 3: Consistency Audit

User: "Audit the app for button style consistency"

Implementation:

**Phase 1: Scope**
- Audit: All button elements
- Goal: Ensure consistent styling

**Phase 2: Discovery**
- Find all buttons in codebase
- Identify button component(s)

**Phase 3: Execute**
- Check each button against style guide
- Document inconsistencies

**Phase 4: Report**
- Buttons using correct component: [N]
- Buttons with inconsistent styles: [N]
- Buttons using deprecated patterns: [N]

**Phase 5: Fix**
- Standardize all buttons to design system

Best Practices

1. Be Systematic, Not Random

Good:

Auditing all form submissions:
1. Login form
2. Registration form
3. Password reset form
4. Contact form
5. Newsletter signup
...
(Methodical, complete)

Poor:

Checking some forms:
- Login form
- Maybe that contact thing
- Whatever else I find
(Random, incomplete)

2. Document Everything

For each audit item, record:

• What was checked
• How it was checked
• Result (pass/fail)
• Evidence (what you observed)

3. Use Categories

Group findings into meaningful categories:

• By severity (critical, major, minor)
• By type (functional, UI, consistency, performance)
• By component (forms, navigation, data display)

4. Make Findings Actionable

Good:

Issue: Registration form submit button doesn't work
Location: src/components/RegisterForm.tsx:45
Root cause: onClick handler missing
Fix: Add onClick={handleSubmit}
Effort: 5 minutes

Poor:

Issue: Some button broken somewhere
Fix: Fix it

Red Flags - Don't Do This

| Action | Why It's Wrong |

|--------|----------------|

| Skip creating checklist | Will miss things, duplicate work |

| Test randomly without system | Incomplete coverage |

| Not documenting findings | Can't prioritize or fix later |

| Audit without clear criteria | Don't know what "pass" means |

| Fix while auditing | Confuses audit with remediation |

| Ignore patterns | Miss systemic issues |
