Pin Your Execution Model with enforceAvailableModels — Don't Let Auto-Upgrades Burn Through Your Credits

From June 15, monthly credits become non-rolling. This is a setup-layer approach to keep subagents and fallbacks from silently upgrading to pricier models, using enforceAvailableModels to pin the model set from the managed-settings layer, with a verification step you can run in CI.

Context Budgets for Nested Subagents: Designing Contracts So 5-Level Delegation Doesn't Lose Quality

Once subagents could nest, deeper delegation made summaries thinner and reruns more frequent. Here is how I rebuilt quality by adding four contracts between layers: token budgets, a handoff schema, failure isolation, and an independent grader.

A Three-Tier fallbackModel Setup for Claude Code — Keeping Unattended Runs Alive Through Overload Mornings

How I run Claude Code with a three-tier fallbackModel chain so overnight batches survive overload errors: logging which model actually ran, measuring quality drift on fallback days, and pairing it with deny rules.

Fixing Overlapping Paywall and Review Dialogs on Android with a Central ModalGate

How I fixed three dialogs — paywall, review prompt, and rewarded-ad promo — stacking on top of each other with a priority-based central gate, plus the three dismiss-leak paths a Claude Code design review uncovered.
