PSR Compliance Audit

Perform a comprehensive PSR compliance audit with actionable improvement recommendations.

Input Parsing

Parse $ARGUMENTS to extract path, level, and optional meta-instructions:

Format: <path> [level] [-- <meta-instructions>]

Arguments:
- path: Target directory or file (required, default: current directory)
- level: Audit depth - quick|standard|deep (optional, default: standard)
- -- meta-instructions: Additional focus areas or filters (optional)

Examples:
- /acc:audit-psr ./src
- /acc:audit-psr ./src deep
- /acc:audit-psr ./src quick
- /acc:audit-psr ./src -- focus on PSR-12 only
- /acc:audit-psr ./src deep -- focus on interfaces
- /acc:audit-psr ./src -- level:deep (backward compatible)

Parsing rules:

1. Split $ARGUMENTS by -- (space-dash-dash-space)
2. First part = positional arguments, Second part = meta-instructions
3. In positional arguments, check if last word is a valid level (quick|standard|deep)
4. If level found → extract it; remaining = path
5. Also accept level:quick|standard|deep in meta-instructions (backward compatibility)
6. Priority: positional > meta-instruction > default (standard)
7. Default path: current directory (if empty)

Pre-flight Check

1. Verify the path exists:

   • If $ARGUMENTS is empty, audit current directory
   • If path doesn't exist, report error and stop

2. Verify it's a PHP project:

   • Check for composer.json or *.php files
   • If not a PHP project, report and stop

3. Check PSR tooling:

   • Look for .php-cs-fixer.php, phpcs.xml, phpstan.neon
   • Look for PSR packages in composer.json (psr/log, psr/cache, psr/http-message, etc.)
   • Note available vs missing tooling in report

Audit Levels

Level is an optional positional parameter. Default: standard.

Level	Scope	What's Checked
quick	Structure only	declare(strict_types=1), namespace conventions, basic naming
standard	Full analysis	PSR-1/12 coding style, PSR-4 autoloading, interface detection, file:line references
deep	Standard + quality	Standard + PSR interface implementation quality, method signatures, return types, docblock compliance

Severity Levels

Level	Symbol	Criteria
Critical	🔴	Missing strict_types, wrong namespace-to-path mapping, broken autoloading
High	🟠	PSR-12 violations (indentation, line length, brace placement)
Medium	🟡	Naming convention issues, missing type declarations
Low	🟢	Style suggestions, optional improvements

Meta-Instructions Guide

Instruction	Effect
focus on PSR-12	Deep PSR-12 coding style analysis
focus on interfaces	Analyze PSR interface implementations in depth
skip autoloading	Exclude PSR-4 autoloading checks
PSR-12 only	Only check PSR-12 coding style
level:quick	Quick audit (same as positional quick)
level:standard	Standard audit (same as positional standard)
level:deep	Deep audit (same as positional deep)
detailed report	Maximum detail in report
на русском	Report in Russian

Instructions

Use the acc:psr-auditor agent to perform a comprehensive PSR compliance audit:

Task tool with subagent_type="acc:psr-auditor"
prompt: "Perform PSR compliance audit on [PATH]. Audit level: [LEVEL]. [META-INSTRUCTIONS if provided]

Use TaskCreate/TaskUpdate for progress visibility. Create tasks for each audit phase.

Analyze:
1. PSR-1/PSR-12 Coding Style — strict_types, naming (PascalCase classes, camelCase methods, UPPER_CASE constants), indentation, line length, brace placement
2. PSR-4 Autoloading — composer autoload config, namespace-to-path mapping, file naming
3. PSR Interface Implementations — detect PSR-3, PSR-6, PSR-7, PSR-11, PSR-13, PSR-14, PSR-15, PSR-16, PSR-17, PSR-18, PSR-20 usage and quality

For each violation provide:
- Severity (🔴/🟠/🟡/🟢)
- File:line location
- What's wrong and how to fix it

Generate a detailed report with skill recommendations."

If no path is provided, audit the current project root.

What It Checks

1. PSR-1/PSR-12 Coding Style

• declare(strict_types=1) usage
• Class naming (PascalCase)
• Method naming (camelCase)
• Constant naming (UPPER_CASE)
• Property naming (camelCase)
• Line length limits (120 chars max)
• Indentation (4 spaces, no tabs)
• Brace placement (Allman for classes, K&R for control)
• Use statement ordering
• Blank line rules

2. PSR-4 Autoloading

• Composer autoload configuration
• Namespace-to-path mapping correctness
• File naming matches class names
• One class per file

3. PSR Interface Implementations

• Detects PSR-3, PSR-6, PSR-7, PSR-11, PSR-13, PSR-14, PSR-15, PSR-16, PSR-17, PSR-18, PSR-20
• Implementation completeness
• Method signature correctness
• Recommends missing implementations

Expected Output

# PSR Compliance Audit Report

**Project:** [NAME] | **Date:** [DATE] | **Level:** [quick|standard|deep]

## 1. Executive Summary

| Category | Score | 🔴 | 🟠 | 🟡 | 🟢 |
|----------|-------|-----|-----|-----|-----|
| PSR-1 Basic | X/100 | N | N | N | N |
| PSR-12 Style | X/100 | N | N | N | N |
| PSR-4 Autoloading | X/100 | N | N | N | N |
| PSR Interfaces | X/100 | N | N | N | N |

**Overall Score:** X/100 | **Risk Level:** LOW/MEDIUM/HIGH/CRITICAL

## 2. PSR-1/PSR-12 Compliance

### 🔴 Critical Issues
- **Location:** `file.php:line` — Missing `declare(strict_types=1)` — Add declaration

### 🟠 High Priority
- **Location:** `file.php:line` — Wrong brace placement — Move to next line

### 🟡 Medium
- **Location:** `file.php:line` — Method naming — Rename to camelCase

## 3. PSR-4 Autoloading

| Namespace | Path | Status |
|-----------|------|--------|
| App\Domain | src/Domain/ | ✅ |
| App\Infra | src/Infrastructure/ | 🟠 Mismatch |

## 4. PSR Interface Detection

| PSR | Package | Implemented | Quality |
|-----|---------|-------------|---------|
| PSR-3 | psr/log | ✅ | Good |
| PSR-7 | — | ❌ Not found | — |
| PSR-11 | psr/container | ✅ | Good |

## 5. Skill Recommendations

| Gap | Skill | Command |
|-----|-------|---------|
| No PSR-3 logger | `acc:create-psr3-logger` | `/acc:generate-psr logger` |
| No PSR-7 messages | `acc:create-psr7-http-message` | `/acc:generate-psr http-message` |
| No PSR-15 middleware | `acc:create-psr15-middleware` | `/acc:generate-psr middleware` |

## 6. Action Items

1. 🔴 Add `declare(strict_types=1)` to N files
2. 🟠 Fix PSR-12 brace placement in N files
3. 🟡 Rename N methods to camelCase
4. 🟢 Consider implementing PSR-3 logger

Usage Examples
