# /kai-budget — Spend Allocated Against Unit Economics, Not Vibes ## Objective A marketing budget with defensible arithmetic behind every line: unit economics modeled or explicitly estimated, channel-by-channel allocation with expected CAC and volume, three ROI scenarios, a ramp schedule, and the kill/scale criteria that decide what happens next quarter. The number the user leaves with is one they could defend to a board. Broken economics are the first finding, not a footnote. An LTV:CAC below 1:1 or a payback beyond 18 months changes the whole recommendation. ## Done when Work type `strategy-plan` — floor **E3/C3/O1** (`harness/eco-floors.yaml`). - **E3** — a named human approved the exact budget document. Approving the plan is not authorizing the spend; spend authorization is a separate decision. - **C3** — `banned_word_check` clean, every projection carries a confidence level, every assumption that needs validation is flagged as such, and someone other than the author read it end to end. - **O1** — every allocation line names the metric that proves it worked (CAC, volume, payback), its baseline, its threshold, and its owner, recorded before the first dollar moves. A budget with no predeclared thresholds cannot be graded later. ## Constraints - **Read `MARKETING.md` from the project root first.** It carries product, ICP, value prop, monetization, voice, current channels, and competitive landscape. If it does not exist, build it from the codebase — CLAUDE.md, README.
