Follow the dsh CLI default channel (npm latest), not @next.
Install
dsh plugin --profile exec add @deepseek-ai/dsh-headless@$(npm view @deepseek-ai/dsh version)
dsh plugin --profile exec add dsh-exec-extension
dsh --profile exec --helpOfficial dsh is npx @deepseek-ai/dsh. Headless’s own latest tag is stale, so the first line uses the CLI version. Only use @next if you installed dsh@next.
