# Build Until Agreed The builder is the worst judge of whether the work is done. This skill writes down what "done" means *before* building, then lets independent auditors decide — and checks their claims before acting on them. **Standing rules — they hold for the whole run, every round:** 1. **Problem first.** No contract without a named user and the pain it removes. If there isn't one, say so and stop — we don't build for the sake of building. 2. **Auditors are blind and read-only.** Fresh, **unnamed**, never `fork` — each round. They get the contract file, the commit range and the harness — never the ledger, the builder's reasoning, earlier findings, or each other's verdicts. The ledger is git-ignored, so no commit range can show it to them. 3. **Nothing is fixed until it is verified.** A blocking finding is a claim until a separate verifier reproduces it. Documented decisions are not defects. 4. **Freeze while auditing.** Commit before a round; no edits until every auditor returns. 5. **Prefer cutting to adding.** Before each fix, name what it protects. If nothing, cut. 6. **Never merge. Never push to the default branch.** Work on a branch; the human merges. This is enforced here, in the workflow — `Bash(git *)` does not enforce it. 7. **Explain progress.** After every round, print the round block (see `reference/contract-and-ledger.md`) so the user always knows where things stand and why. ## Preferences _On startup, use Read to load `~/.claude/s...
