WP Audit Standards

This skill defines the audit criteria, severity levels, report format, and quality thresholds used by all wp-audit agents.

---

Severity Levels

Severity	Meaning	Action
CRITICAL	Security vulnerability, complete accessibility failure, broken core functionality	Fix immediately
WARNING	Best-practice violation, degraded UX, performance issue	Fix before delivery
INFO	Optimization opportunity, minor improvement	Fix when convenient

---

Report JSON Schema

All audit agents MUST output findings in this format:

{
  "category": "security|seo|a11y|performance|best-practices",
  "tier": 1,
  "issues": [
    {
      "severity": "critical|warning|info",
      "code": "SEC-001",
      "message": "Human-readable description",
      "file": "path/to/file.php",
      "line": 42,
      "auto_fixable": true,
      "fix_method": "Description of how to fix"
    }
  ],
  "summary": {
    "total": 0,
    "critical": 0,
    "warning": 0,
    "info": 0,
    "auto_fixable": 0
  }
}

Field Requirements

• category — one of: security, seo, a11y, performance, best-practices
• tier — integer 1–3 indicating which audit tier produced the finding
• issues — array of issue objects (may be empty)
• severity — one of: critical, warning, info
• code — prefixed issue code (see Issue Code Prefixes below)
• message — human-readable description of the problem
• file — relative path to the affected file
• line — line number (0 if not applicable)
• auto_fixable — boolean indicating whether the agent can safely fix this
• fix_method — description of the fix approach
• summary — counts aggregated from the issues array

Issue Code Prefixes

Prefix	Domain
SEC-xxx	Security
SEO-xxx	SEO
A11Y-xxx	Accessibility
PERF-xxx	Performance
WP-xxx	Best Practices

---

Audit Tiers

Tier 1 — Code-only (always available)

File scanning via Read, Grep, Glob. No runtime environment required.

Tier 2 — + WP-CLI runtime (when .wp-create.json exists)

Plugin management, option reading, database queries. Requires a working WordPress installation with WP-CLI access.

Tier 3 — + External skills (when web-quality-skills installed)

Lighthouse-style browser audits. Requires the web-quality-skills package for browser-based testing.

Performance Budgets

Resource	Budget
CSS compressed	<100KB
JS compressed	<300KB
Total page weight	<1.5MB
Images above-fold	<500KB
Fonts total	<100KB

---

Accessibility Thresholds

Requirement	Minimum
Normal text contrast	4.5:1
Large text contrast (>=18px or >=14px bold)	3:1
UI component contrast	3:1
Touch target size	44x44 CSS pixels
Minimum gray on white passing 4.5:1	#767676

---

Core Web Vitals Targets

Metric	Good	Needs Work	Poor
LCP	≤2.5s	2.5s–4s	>4s
INP	≤200ms	200ms–500ms	>500ms
CLS	≤0.1	0.1–0.25	>0.25

---

Auto-Fix Classification

Auto-fixable

Agent can safely fix without risk of breaking the site:

• Add missing attributes (e.g., alt, aria-label, loading)
• Append CSS rules
• Set wp-config constants
• Install/configure plugins via WP-CLI
• Add missing escaping wrappers
• Add missing nonce checks to simple forms

Manual-only

Requires human judgment:

• Restructuring templates
• Changing application logic
• Removing code
• Design decisions
• Complex refactoring

---

Deduplication Rules

When multiple agents find the same issue:

• Security agent owns vulnerability-class checks (XSS, SQLi, CSRF)
• Practices agent owns coding-standards checks (escaping for theme review compliance)
• SEO agent owns heading hierarchy for search ranking context
• A11y agent owns heading hierarchy for screen reader navigation context
• Command deduplicates identical file:line findings, keeping the highest severity

---

Agent Interaction Model

All plugin interaction via WP-CLI options/meta, never PHP APIs:

Operation	Command
Read plugin config	$WP option get <option_name>
Write plugin config	$WP option update/patch
Seed data	$WP post meta update
Complex operations	$WP eval "php code"
Install plugins	$WP plugin install --activate
Theme modifications	Direct file Edit/Write
wp-config changes	$WP config set
