Add the openrouter-chat-cli fragment to this existing repository. 1. Run npx @steamfield/stacks show openrouter-chat-cli --json and check that it fits the project. If it does not, explain why before changing files. 2. Run npx @steamfield/stacks add openrouter-chat-cli and follow the brief it prints. 3. In this repository, run npx @steamfield/stacks verify. Fix failures without weakening or skipping verification steps. 4. Summarize what changed and the verification result. Quote published stats only when they are available, including their interval and sample size. The stacks docs, written for agents, are at https://stacks.steamfield.io/llms.txt.

Or use the terminal

npx @steamfield/stacks add openrouter-chat-cli
