claude-api

claude-api is a skill for Claude Code, Codex from warpdotdev/warp. It costs 193 tokens per session (7,884 once invoked), scanned A, original, AGPL-3.0.

A guide for building, debugging, and improving applications that use the Claude API or Anthropic software libraries. The Claude API is a service that lets applications send requests to Anthropic's Claude models.

In plain words
What is it for?
It is for creating Claude API apps, fixing Anthropic SDK code, improving integrations, and moving code between Claude model versions.
Why use it?
It helps keep Claude integrations working across model changes and includes prompt caching in new applications to avoid repeating unchanged instructions.

About the project

Warp is an agentic development environment built around a terminal, combining a coding agent with tools for software development and team workflows. Developers can use its built-in agent or connect external CLI agents, while teams can define and deploy software factories in code.

SkillSpector: 2 findings, up to medium

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

  • medium Memory Poisoning · line 257
    Skill attempts to fill the context window with filler content, displacing legitimate instructions and safety constraints. This can degrade agent performance or bypass safety boundaries.
    Fix: Implement context-window management that detects and rejects padding or stuffing attempts. Prioritize system instructions over user-injected content.
  • medium Excessive Agency · line 317
    Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.
    Fix: Add human-in-the-loop confirmation for destructive, irreversible, or high-impact operations. Never auto-execute commands that modify files, send data, or alter system state.

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 1mo 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.

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

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.
