𝟭. 𝗧𝗛𝗘 𝗛𝗔𝗥𝗡𝗘𝗦𝗦 𝗔𝗡𝗗 𝗧𝗛𝗘 𝗕𝗥𝗔𝗜𝗡

→ The harness is local: your prompts, your skills, your tools.

→ The brain is the model underneath. Swap it, keep everything else.

𝟮. 𝗪𝗛𝗬 𝗧𝗛𝗘 𝗗𝗘𝗙𝗔𝗨𝗟𝗧 𝗖𝗢𝗦𝗧𝗦 𝗬𝗢𝗨

→ By default, a subagent runs on whatever model the parent was using.

→ So a one-line file rename bills at heavy-reasoning rates.

𝟯. 𝗠𝗢𝗗𝗘𝗟-𝗧𝗔𝗦𝗞 𝗔𝗟𝗜𝗚𝗡𝗠𝗘𝗡𝗧

→ Opus for the hard architectural thinking.

→ Sonnet for daily writing and coding.

→ Haiku or a local model for the chores nobody should pay for.

𝟰. 𝗕𝗥𝗜𝗡𝗚 𝗔𝗡𝗬 𝗕𝗥𝗔𝗜𝗡

→ Connect free, paid or local. OpenRouter alone reaches hundreds of models.

→ Ollama and LM Studio run them on your own machine, for nothing.

𝟱. 𝗧𝗜𝗘𝗥 𝗥𝗢𝗨𝗧𝗜𝗡𝗚 𝗜𝗦 𝗧𝗛𝗘 𝗥𝗘𝗔𝗟 𝗧𝗥𝗜𝗖𝗞

→ Fable, Opus, Sonnet and Haiku can each point at a different provider.

→ Forty-plus backends behind one harness, from Bedrock to Groq to DeepSeek.

→ So the tiers you lean on least can quietly run on something free.

𝟲. 𝗦𝗘𝗧𝗨𝗣 𝗔𝗡𝗗 𝗞𝗘𝗬𝗦

→ One terminal command, a few yes or no answers, and you get an alias.

→ The admin panel holds your keys. Set spend limits, switch models mid-task.

Harness = what you built.

Brain = what you rent.

Alignment = what you keep.
