Source insight (Samantics / @inferencepoint): "Almost every single thing I see that claims to run a robust proxy is not aware of the cache-busting tricks Claude Code and Codex have implemented in the harness when you try to hook it up to your own gateways." Keep an eye on your cache hit rate.
Gateway Cache Awareness is a community-contributed Claude Code skill in the engineering-misc sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/gateway-cache-awareness/ and loads when your prompt matches the skill's trigger.
When to invoke it: Use when configuring a custom base_url/gateway, debugging exploding token costs or slow first-token latency behind a proxy, or evaluating an "OpenAI/Anthropic-compatible" gateway. Watch the cache hit rate — most proxies silently break it.
The Gateway Cache Awareness Claude Code skill is built for software engineers, backend developers, full-stack teams, and technical leads building and maintaining production systems. It's part of ClaudSkills (also referred to as Claude Skills or Claude Code Skills) — the open community-curated registry of 158,000+ SKILL.md files for Anthropic's Claude Code agent and the wider Claude ecosystem (Claude API, Claude Agent SDK).
