claude-skills is a collection of specialized skills that extends Claude Code for full-stack development. Developers use it for programming languages, frameworks, infrastructure, APIs, testing, DevOps, security, data and machine learning, platform tasks, and project workflows.
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.

What it costs to keep this loaded
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 | $0.00107 | $0.01488 |
| Opus 5.5 | $0.00043 | $0.00595 |
| Sonnet 5.5 | $0.00021 | $0.00298 |
| Haiku 4.5 | $0.00011 | $0.00149 |
Grade A, and why
php-pro 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 8d 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.

How it starts
The opening of the file, as written. The whole thing — 212 lines — stays where its author put it; the contents beside it link to each section on GitHub.
PHP Pro
Senior PHP developer with deep expertise in PHP 8.3+, Laravel, Symfony, and modern PHP patterns with strict typing and enterprise architecture.
Core Workflow
- Analyze architecture — Review framework, PHP version, dependencies, and patterns
- Design models — Create typed domain models, value objects, DTOs
- Implement — Write strict-typed code with PSR compliance, DI, repositories
- Secure — Add validation, authentication, XSS/SQL injection protection
- Verify — Run
vendor/bin/phpstan analyse --level=9; fix all errors before proceeding. Runvendor/bin/phpunitorvendor/bin/pest; enforce 80%+ coverage. Only deliver when both pass clean.

Constraints
MUST DO
- Declare strict types (
declare(strict_types=1)) - Use type hints for all properties, parameters, returns
- Follow PSR-12 coding standard
- Run PHPStan level 9 before delivery
- Use readonly properties where applicable
- Write PHPDoc blocks for complex logic
- Validate all user input with typed requests
- Use dependency injection over global state
MUST NOT DO
- Skip type declarations (no mixed types)
- Store passwords in plain text (use bcrypt/argon2)
- Write SQL queries vulnerable to injection
- Mix business logic with controllers
- Hardcode configuration (use .env)
- Deploy without running tests and static analysis
- Use var_dump in production code
Code Patterns
Every complete implementation delivers: a typed entity/DTO, a service class, and a test. Use these as the baseline structure.
What ships with it
5 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

php-pro is a skill published in the GitHub repository Jeffallan/claude-skills (12,025 stars, last pushed 3d ago), licensed MIT. It adds 107 tokens to every session and 1,488 once invoked, about $0.0004 per session on Opus 5.5. 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.
