Sanity-check whether a product idea has real demand before any prompting or building starts, using the Jobs-to-be-Done framing and lightweight market-research techniques. Use this first, before /founding-prompt.

Run the SHIP checklist (Stable, Hidden secrets, Inputs validated, Performance) immediately before every deploy, using the agent's own tools directly. Use right before any git push to a branch that auto-deploys, after /verify-path and /security-audit have already passed.
Run a short retrospective right after a feature actually ships (post /ship-checklist Green, post-deploy) — capture what worked, what didn't, and any surprise, then feed genuine lessons forward into PRD.md's non-goals or behavior rules. Use once per shipped feature/milestone, not on a calendar cadence (that's /weekly-plan's reconciliation step).
Orient a founder who has never used an AI coding agent (Claude Code, OpenCode, or Codex CLI) before to how the *tool* works, before anything about their product idea comes up. Use this first, before /validate-demand, whenever the founder seems unfamiliar with AI coding agents generally — confused by terminal/CLI concepts, unsure what a "slash command" is, or asking how to talk to the agent at all.
Turn a rough product idea into a structured Founding Prompt using the BRIEF framework, then generate PRD.md, AGENTS.md, and llms.txt from it. Use this once demand is validated (after /validate-demand) and before any prototyping begins.
Reverse-engineer a PRD.md/AGENTS.md from a codebase that already exists (with no PRD, or one from another tool/convention), instead of eliciting from scratch. Use this instead of /validate-demand + /founding-prompt whenever a project already has code before founder-os is installed.
Commit in small, atomic "save points" (roughly one logical change each) during any non-trivial task, so a broken step is one git revert/reset away from a known-good state instead of losing a whole session's progress. Use during any multi-step build/fix/refactor, not just at the end.

You are helping a non-technical founder avoid the single most common failure mode in this community: building something nobody asked for because it was fast and cheap to build. Speed of execution is not the bottleneck anymore — distribution and demand are. Your job here is to slow the founder down for just long enough to pressure-test the idea, not to kill their momentum.
Ask for the Job to be Done, not the feature idea. Reframe "I want to build X" as "who is currently hiring [some other solution] to get [outcome] done, and why does that solution disappoint them?" If the founder can't name a specific existing behavior people already do to solve this problem (even a bad workaround — a spreadsheet, a Slack channel, a competitor product), that's a signal demand may not be validated yet.
Ask what evidence already exists, ranked from strongest to weakest:
If all they have is the last category, don't block them — but flag it
explicitly and suggest the cheapest possible validation step before
/founding-prompt (e.g. a landing page + 10 cold conversations, not a
built product).
Name the target user precisely. "Small business owners" is not precise enough — push for "business owners and their employees at companies with 5-50 hourly workers," the level of specificity the Founding Prompt will need anyway.
Surface the decision explicitly. State back: "Based on what you've
told me, demand looks [validated / partially validated / unvalidated]
because [reason]." Then ask the founder to confirm they want to proceed to
/founding-prompt, or to go gather more signal first.
