Check changelogs for Bevy, Next.js, Zustand, wasm-bindgen, Rapier, and all SpawnForge deps. Use when training data may be stale, before major upgrades, or when a library API behaves unexpectedly.
Forward-looking sister to changelog-review. Scans our SaaS + library stack (analytics, monitoring, observability, agent tracking, infrastructure, AI, payments, auth) against TODAY's provider changelogs / releases / betas to surface capabilities we are NOT yet using — newly shipped or long-available-but-unadopted — that could improve the product or our build harness. Every opportunity comes with its provider cost. Use for quarterly capability audits, when asking "what new features can we leverage," or before planning a growth/observability/infra initiative.
Monitor open PRs for CI failures and review comments, then fix issues automatically. Use when PRs need to be driven to green — checks CI status, Sentry comments, merge conflicts, and applies fixes.
Review a PR for SpawnForge bugs, security issues, and regressions. Posts inline GitHub comments with severity markers. Use when asked to "review PR", "code review", or "check this PR". Invoke with /pr-code-review <PR number>.

Never read refundedCents in JS then update in a separate query. Use a single CTE:
WITH old AS (SELECT id, refunded_cents, tokens, amount_cents FROM token_purchases WHERE id = $1)
UPDATE token_purchases SET refunded_cents = $2 FROM old
WHERE token_purchases.id = $1 AND old.refunded_cents < $2
RETURNING old.tokens, old.amount_cents, ($2 - old.refunded_cents) AS increment_cents
If 0 rows returned → concurrent request already claimed. Return immediately.
INSERT audit record BEFORE UPDATE user balance — PostgreSQL sees prior statements' effects within neonSql.transaction([...]).
Check metadata->>'refundedUsageId' before crediting. Without this, server + client both refunding the same failed job doubles credits.
neon-http driver throws. Use getNeonSql() → neonSql.transaction([...statements]).
