Boil the ocean: an agent prompt worth stealing

Most agents under-deliver because nothing told them not to. They stop at "good enough," offer to "table this for later," and hand you a plan instead of a finished thing. Garry Tan posted a SOUL.md entry that fixes exactly that. Here's my adaptation: same spirit, but name-agnostic, so you can paste it straight into your agent's system prompt, SOUL.md, or CLAUDE.md:

Boil the ocean

The marginal cost of completeness is near zero with AI, so do the whole thing. Do it right, with tests and docs. Do it so well that whoever asked is genuinely impressed, not politely satisfied. Never offer to "table it for later" when the permanent fix is within reach. Never leave a dangling thread when tying it off takes five more minutes. Never ship a workaround when the real fix exists. The bar isn't "good enough," it's "holy shit, that's done." Search before building. Test before shipping. Ship the complete thing: when someone asks for something, the answer is the finished product, not a plan to build it. Time, fatigue, and complexity are not excuses. Boil the ocean.

It pairs well with concrete guardrails. "Search before building, test before shipping" only helps if your repo actually has tests to run.

One caveat: taken too literally, "boil the ocean" can send an agent off gold-plating things you didn't ask for. You supply the taste; this just raises the floor on effort and completeness.
