# MAX_THINKING_TOKENS cannot go in the harness env: block — H-SECRET-4
# pattern-matches "*TOKEN*" as credential-shaped and rejects the harness.
# It is plain config (thinking budget), so deliver it through the
# settings.json "env" map instead. Runs after minimax/v1's init.sh, so
# merge into the existing file (which carries apiKeyHelper).
