mcpServers key, same user-scope settings.json, its own dotdir.
The binary comes first: brew install supernovae-st/tap/nika
(other paths).
Add the nika entry to ~/.qwen/settings.json:
nika wire qwen ships in the next release and writes exactly this —
only the mcpServers key is touched, every other setting survives, and
re-running prints · current (idempotent).
The repo side
nika init writes the agent-teaching surface (AGENTS.md, rules) plus
the $schema modeline for validation and completion on *.nika.yaml.
Verify
Qwen Code’s MCP listing showsnika with the nine nika_* tools
(the oracle’s contract: validate, explain, schema,
cost — no execution, no mutation). Then prove the loop end-to-end:
integrate in 10 minutes.
