Costs

See where the money actually goes - vendor by vendor, before you sign the next renewal. Every vendor the project pays (Anthropic · Vercel · Stripe · others) with a current spend band, the scale ceiling where it starts to hurt, and the mitigation to reach for when it does. Lives at .claude/brain/costs.md.

What it does for you

A vendor table you can defend at a board meeting.Current monthly band and cost driver per vendor, projected bands for the launch and hosted-scale phases, and a scale ceiling with its mitigation for the vendors that have one. Hand-edited, so it is only as current as the last time someone read it against the bill.
The pain point is written down before the bill grows.Every vendor carries a spend band for each phase. The five that scale first (Vercel, Neon, Stripe, Anthropic, Sentry) also carry the pain point that arrives first and what to do about it, so the “what happens when this gets expensive?” answer is on the page before the invoice forces it.
Lined up with Telemetry & Billing outcomes.Costs is the static “what we pay for”; Telemetry + Billing outcomes are the live “what we actually spent.” Both should converge or one is wrong.

Configure

Nothing - hand-edit the markdown when a vendor is added, removed, or repriced. The HTML page is rendered from that markdown on request, so there is no second copy to sync.

Use it well

Before signing any new vendor: add the row first, then sign. Forces the “what triggers us to switch?” question while it's still cheap to leave. Quarterly: re-read the bands against the last invoice - if the band's wrong, update before the next planning window so budgets price correctly.
