AI Project Showcase: WordPress Plugin Clone Safety Checker

Section 1 — Product Overview

1.1 Product name and tagline

Name: WordPress Plugin Clone Safety Checker
Tagline: A comprehensive command-line tool to identify issues when cloning WordPress plugins
Current status: Active — v1.0.0
First commit / project start: ~February 18, 2026 💡 [CLAUDE NOTE: inferred from filesystem timestamps on plugin-clone-checker.php and README.md; no git history in this directory]

1.2 What it is

The WordPress Plugin Clone Safety Checker is a standalone PHP CLI script that scans a cloned WordPress plugin directory for leftover references to the original plugin’s prefix. When cloning a WordPress plugin (a common ITI development pattern), dozens of identifiers must be updated — class names, constants, function names, option names, database tables, AJAX actions, nonces, text domains, hooks, JavaScript objects, CSS classes, transients, cron hooks, REST routes, meta keys, shortcodes, widget IDs, and plugin headers. Missing even one can cause fatal errors, data conflicts, security issues, or silent functionality failures. The tool automates this verification across 19 check categories, scanning PHP, JS, CSS, JSON, MD, TXT, and HTML files with color-coded terminal output.

1.3 What makes it meaningfully different

• WordPress-specific check categories: 19 targeted checks covering every WordPress-specific identifier pattern (not just generic string search)
• Automatic case variation handling: Derives snake_case, kebab-case, PascalCase, camelCase, and CONSTANT_CASE from the original prefix and checks all variations
• Zero dependencies: Single PHP file, no Composer, no npm — runs anywhere PHP CLI is available
• CI/CD compatible: Exit code 0 (clean) or 1 (issues) enables integration with automated pipelines
• Born from real need: Created specifically to validate the ITI Agent Plugin POC → production clone process

1.4 Platform and deployment context

Platform: Standalone PHP CLI script (not a WordPress plugin)
Deployment: Run from any terminal with PHP CLI
Primary interface: Command line with ANSI color-coded output

Section 2 — User Needs and Problem Statement

2.1 Target user

Primary user: WordPress plugin developers cloning plugins for customization
Secondary users: AI toolbox during plugin clone operations; CI/CD pipelines for automated validation
User environment: Development workstation or CI runner with PHP CLI

2.2 The problem being solved

WordPress plugin cloning is a common development pattern (ITI uses it extensively — GD Chatbot → ITI Chatbot, ITI Agent POC → ITI Agent Plugin). The process requires updating identifiers across dozens of files in multiple case formats. Manual search-and-replace is error-prone: a missed constant causes “undefined constant” errors, a missed option name causes settings conflicts with the original plugin, a missed nonce name causes security check failures, a missed AJAX action causes silent JS failures. There was no purpose-built tool to comprehensively validate that all identifiers had been updated.

2.3 Unmet needs this addresses

Need	How the product addresses it	Source of evidence
Catch missed class names	Checks class definitions, new, static calls, instanceof with PascalCase prefix	checkClassNames() in source
Catch missed options/settings	Checks get_option, update_option, delete_option, register_setting with snake_case prefix	checkOptionNames()
Catch missed AJAX mismatches	Checks both PHP wp_ajax_* hooks and JS action parameters	checkAjaxActions()
Catch missed nonce names	Checks wp_create_nonce, wp_verify_nonce, check_ajax_referer	checkNonceNames()
Catch missed text domains	Checks __(), _e(), esc_html__(), esc_attr__(), _n() with kebab-case domain	checkTextDomains()
Validate plugin headers	Checks Plugin Name for original prefix, Text Domain vs folder name match	checkPluginHeaders()

2.4 What users were doing before this existed

Manual grep/search across files, often missing case variations or WordPress-specific patterns like nonce verification functions, AJAX action hooks, or wp_localize_script object names. The alternative was deploying and discovering errors at runtime.

Section 3 — Market Context and Competitive Landscape

3.1 Market category

Primary category: WordPress development tooling / code quality
Market maturity: Niche — plugin cloning is common but dedicated tooling is rare
Key dynamics: Most WordPress developers use generic text search tools or manual review

3.2 Competitive landscape

Product / Company	Approach	Strengths	Key gap this project addresses	Source
⚡ grep/ripgrep	Generic text search	Universal, fast	No WordPress-specific pattern awareness, no case variation handling, no categorized output	[CLAUDE NOTE: inferred from tool design]
⚡ IDE find-and-replace	Manual search/replace	Visual, interactive	No automated validation, no CI integration, misses cross-file patterns	[CLAUDE NOTE: inferred]
⚡ WP-CLI scaffold	Plugin scaffolding	Creates new plugins correctly	Doesn’t validate cloned plugins, no detection of leftover identifiers	[CLAUDE NOTE: inferred]

3.3 Market positioning

Internal development tool within the ITI ecosystem, purpose-built for the plugin cloning workflow that ITI uses to create derivative products. Could be open-sourced as a WordPress development community tool. [CLAUDE NOTE: positioning inferred from usage context]

3.4 Defensibility assessment

Low defensibility as a standalone tool (simple concept, single file). Value is in the comprehensive WordPress-specific check list (19 categories) and the case variation handling. Primary value is as a process tool within the ITI development workflow. [CLAUDE NOTE: inferred]

Section 4 — Requirements Framing

4.1 How requirements were approached

Requirements derived from real-world experience cloning ITI plugins — the README’s “Common Issues Found” table documents actual failure patterns encountered during plugin cloning. The tool was built to codify this institutional knowledge into an automated check.

4.2 Core requirements

1. Scan a plugin directory for all references to an original prefix
2. Handle 5 case variations automatically (snake_case, kebab-case, PascalCase, camelCase, CONSTANT_CASE)
3. Check 19 WordPress-specific identifier categories
4. Produce color-coded terminal output grouped by file
5. Distinguish issues (must fix) from warnings (review recommended)
6. Return exit code 0/1 for CI/CD integration
7. Skip irrelevant directories (.git, node_modules, vendor)
8. Scan relevant file types (PHP, JS, CSS, JSON, MD, TXT, HTML)

4.3 Constraints and non-goals

Hard constraints: PHP CLI only; single-file distribution; no external dependencies
Explicit non-goals: Auto-fixing (tool only detects, does not modify); WordPress runtime integration (CLI-only, not a plugin)

4.4 Key design decisions and their rationale

Decision	Alternatives considered	Rationale	Evidence source
Standalone CLI script, not WP plugin	WP-CLI command, Composer package	Maximum portability — runs anywhere PHP is available, no WordPress installation needed	Shebang line #!/usr/bin/env php
19 specific check categories vs generic search	Simple grep, regex-only approach	WordPress-specific patterns (AJAX hooks, nonces, wp_localize_script) need targeted detection	19 check*() methods
Issues vs warnings distinction	Single severity level	CSS class and README mentions may be intentional; AJAX/nonce/constant mismatches are always bugs	$severity parameter in searchFile()
New prefix accepted but not used in checks	Use new prefix for suggestions, auto-fix	Scope limited to detection; user information only — new prefix is displayed but no replacement logic	$newPrefix stored but only in header output

5.3 Knowledge categories

Category	Files / format	Purpose	Update frequency
WordPress identifier patterns	PHP regex patterns in 19 check methods	Detect leftover original-prefix references	As new WordPress patterns are identified
Case variation rules	5 conversion methods	Generate all case forms from a single prefix input	Stable
File type targeting	$scanExtensions array	Focus scanning on relevant file types	As needed
Skip directories	$skipDirs array	Exclude irrelevant directories	As needed

5.4 How the knowledge system was built

1. WordPress plugin architecture patterns (class names, constants, hooks, AJAX, nonces, etc.) encoded as regex patterns
2. Case variation handling built from WordPress naming conventions (snake_case for functions/options, kebab-case for text domains, PascalCase for classes, CONSTANT_CASE for defines)
3. Common issues table in README documents real-world failure patterns from ITI plugin cloning experience
4. 19 check categories represent a comprehensive audit of every place WordPress plugin identifiers appear

5.5 System prompt and agent configuration

System prompt approach: N/A — this is a CLI tool, not an AI agent
Key behavioural guardrails: N/A
Persona / tone configuration: N/A

Section 10 — Product Ideation Story

10.1 Origin of the idea

Created during the ITI Agent Plugin development process — specifically when cloning the POC (iti-agent-plugin-poc) to create the production version (iti-agent-plugin). The complexity of updating all WordPress-specific identifiers across 50+ files motivated building an automated verification tool. [CLAUDE NOTE: inferred from tool’s location in iti-agents/ directory and README examples using iti_agent prefix]

10.2 How the market was assessed

N/A — internal tool built to solve an immediate development workflow need.

10.3 The core product bet

That automated, WordPress-specific identifier checking would prevent deployment failures that manual search-and-replace inevitably misses — and that the investment in building the tool would pay back across multiple future plugin cloning operations.

10.4 How the idea evolved

Started as a solution to a specific problem (ITI Agent POC → production clone) and was built as a reusable tool applicable to any WordPress plugin cloning operation. The comprehensive 19-category check list represents accumulated knowledge from real clone failures. The README’s “Common Issues Found” table codifies this institutional knowledge. [CLAUDE NOTE: inferred from README content and tool design]

Section 11 — Lessons and Next Steps

11.1 Current state assessment

What works well: Comprehensive 19-category checking; automatic case variation handling; clean CLI interface with color output; CI/CD compatible exit codes; zero dependencies
Current limitations: Detection-only (no auto-fix); new prefix argument accepted but unused in checks; no programmatic output format (JSON/CSV) for tool integration
Estimated completeness: 90% [CLAUDE NOTE: inferred — tool is feature-complete for its detection scope; auto-fix and structured output would be enhancements]

11.2 Visible next steps

1. Use the $newPrefix parameter in checks (currently stored but unused)
2. Add auto-fix mode (optional flag to replace original prefix with new prefix)
3. Add JSON/CSV output format for programmatic consumption
4. Add to ITI shared tooling for all plugin clone operations
5. Consider open-sourcing as a WordPress community development tool
