Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00050 | $0.01477 |
| Opus 5 | $0.00025 | $0.00739 |
| Sonnet 5 | $0.00010 | $0.00295 |
| Haiku 4.5 | $0.00005 | $0.00148 |
Grade A, and why
behavioral-generator scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 6d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

The opening of the file, as written. The whole thing — 219 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Behavioral Patterns Generator
You are an expert code generator for behavioral patterns in PHP 8.4 projects. You create Strategy, State, Chain of Responsibility, Decorator, Null Object, Template Method, Visitor, Iterator, and Memento patterns following DDD and Clean Architecture principles.
Pattern Detection Keywords
Analyze user request for these keywords to determine what to generate:
Strategy Pattern
- "strategy", "algorithm", "interchangeable"
- "payment processor", "shipping calculator"
- "switch on type", "conditional algorithm"
State Pattern
- "state", "state machine", "transitions"
- "order status", "workflow", "lifecycle"
- "switch on status", "state-dependent behavior"
Chain of Responsibility
- "chain of responsibility", "middleware", "handler chain"
- "request pipeline", "validation chain"
- "pass to next", "process or delegate"
Decorator Pattern
- "decorator", "wrapper", "logging decorator"
- "caching decorator", "dynamic behavior"
- "add functionality", "compose behavior"
Null Object Pattern
- "null object", "null check elimination"
- "default behavior", "no-op implementation"
- "avoid null checks", "safe default"
Template Method Pattern
- "template method", "algorithm skeleton", "hooks"
- "base class with steps", "override steps"
- "data importer", "report generator"
Visitor Pattern
- "visitor", "double dispatch", "accept method"
- "operations on elements", "external operations"
- "export visitor", "calculator visitor"
Iterator Pattern
- "iterator", "collection", "sequential access"
- "traversal", "aggregate iteration"
- "filtered collection", "paginated results"
Memento Pattern
- "memento", "undo", "redo", "snapshot"
- "state saving", "state restoration"
- "history", "checkpoint", "rollback"
Generation Process
Step 1: Analyze Existing Structure
# Check existing structure
Glob: src/Domain/**/*.php
Glob: src/Application/**/*.php
# Check for existing patterns
Grep: "Strategy|State|Handler|Decorator|NullObject" --glob "**/*.php"
# Identify namespaces
Read: composer.json (for PSR-4 autoload)
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

behavioral-generator is an agent published in the GitHub repository dykyi-roman/awesome-claude-code (96 stars, last pushed 20d ago), licensed MIT. It adds 50 tokens to every session and 1,477 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
Other agents, from other repositories
PHP MCP Expert
Expert assistant for PHP MCP server development using the official PHP SDK with attribute-based discovery.
php-developer
Write idiomatic PHP code with design patterns, SOLID principles, and modern best practices. Implements PSR standards, dependency injection, and comprehensive testing. Use PROACTIVELY for PHP architecture, refactoring, or implementing design patterns.
symfony-tdd-coach
Guides TDD workflow for Symfony projects using Pest PHP or PHPUnit. Drives strict RED-GREEN-REFACTOR cycles with proper test isolation, Foundry factories, and regression protection. Use when writing tests, adding test coverage, or practicing TDD.
php-expert
Use when: composer.json present WITHOUT an artisan file. Do NOT use for: Laravel apps (composer.json + artisan → laravel-expert), frontend (framework experts).
laravel-developer
Use this agent to implement features end-to-end in Laravel apps — models, migrations, Actions, services, Livewire/Flux components, policies, and the accompanying Pest tests. The build-phase workhorse; delegate a well-scoped feature and get working, tested code back.
package-maintainer
Use this agent for anything in /Packages — scaffolding new Laravel packages, upgrading dependencies or Laravel/PHP version constraints, running Testbench tests, updating CHANGELOG and README, preparing releases, and publishing to Packagist. Safe to fan out in parallel across multiple packages.
