What is Claude-PHP-SDK copilot-instructions.md?

Project instructions for a framework-independent PHP software development kit (SDK) for the Claude API. An SDK is a library that helps PHP programs call a service without building every network request themselves.

Use them when adding Claude API endpoints, implementing synchronous or asynchronous clients, handling errors, or organizing PHP classes and dependencies.

They explain the intended API coverage, PHP standards, error handling, and client structure so contributors can keep the library compatible with its Python counterpart and PHP frameworks.

Token cost

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	$0.03375	$0.03375
Opus 5.5	$0.01350	$0.01350
Sonnet 5.5	$0.00675	$0.00675
Haiku 4.5	$0.00337	$0.00337

Measured 2mo ago against content hash 472e14d05927, method: parsed. Prices are Anthropic first-party input rates as of 2026-10-07, from the pricing page.

Security

Grade A, and why

Claude-PHP-SDK copilot-instructions.md 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 2mo 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.

Copilot Instructions for Claude PHP SDK

This is a PHP clone of the Anthropic Python SDK (https://github.com/anthropics/anthropic-sdk-python), designed as a universal, framework-agnostic PHP SDK following PSR standards for easy integration with Laravel, Symfony, Slim, and other frameworks.

Project Goals

API Parity: Full implementation of latest Claude API endpoints (Messages, Files, Batches, Models APIs)
PSR Compliance: Follow PHP Standards Recommendations (PSR-12 coding style, PSR-11 containers for DI)
Dependency Injection Ready: Support framework-agnostic DI patterns for seamless integration
Latest Models & Features: Support Claude Sonnet 4.5, Haiku 4.5, Opus 4.1, plus extended thinking, streaming, tool use, vision, embeddings
Async & Sync Support: Both synchronous and asynchronous clients via Amphp/PHP async patterns
Python SDK Parity: Mirror error handling, configuration, and patterns from the official Python SDK

Key Architectural Patterns

Client Pattern: Anthropic class acts as main entry point, returns resource instances

$client = new Anthropic(apiKey: $key);
$response = $client->messages->create([...]);

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.
