Finds, builds, runs and publishes a stand-in for one API — the owning team's published mock when there is one, otherwise one built from its spec or collection that behaves like the real API, stateful when callers write then read. Use when something needs an API that isn't built or reachable yet (a frontend, client or demo), when other teams should build against your API before it ships, or when asked to mock an API or fake a backend.

What this skill can do

Install

Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.

if [ -e ~/.agents/skills/'api-mocking' ] || [ -L ~/.agents/skills/'api-mocking' ]; then echo 'A skill folder named api-mocking already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/postmanlabs/postman-plugin' "$d" && git -C "$d" checkout --quiet 'e5f3170b693d9bcf4634fa9e1df64f15c9838581' -- 'skills/api-mocking' && mkdir -p ~/.agents/skills && cp -R "$d"/'skills/api-mocking' ~/.agents/skills/'api-mocking' && rm -rf "$d"; fi

Codex reads ~/.agents/skills directly. For Claude Code, Cursor, Copilot, Gemini CLI, Antigravity or OpenCode, also link it. For Claude Code: ln -s ~/.agents/skills/'api-mocking' ~/.claude/skills/'api-mocking' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
