claude-api is a skill for Claude Code, Codex from JiuTian-dev/SupplyChainCortex. It costs 193 tokens per session (7,898 once invoked), scanned A, original, no licence file.

Guidance for building and maintaining applications that call the Claude API or use Anthropic's software library. It also covers moving code between Claude model versions and adding prompt caching, which reuses repeated prompt content.

In plain words
What is it for?
Use it when writing, debugging, optimising, or updating code that imports the Anthropic SDK or calls the Claude API.
Why use it?
It helps avoid common integration and model-migration mistakes when an application depends on Anthropic's services or SDK.

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.

Security

Grade A, and why

claude-api scanned grade A with 1 finding 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 3d 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.

Makes network callslowCapability

Not a fault in itself. Listed so you know the mod talks to something, and to what.

2. **Raw HTTP** (`curl`, `requests`, `fetch`, `httpx`, etc.) — only when the user explicitly asks for cURL/REST/raw HTTP, the project is a shell/cURL project, or the language has no official SDK.

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.
