Manage database, schema, and API evolution safely. Use when a repo has migrations, database schemas, public API schemas, seed data, fixtures, compatibility requirements, rollback conventions, or needs scripts/check-migrations.

Diagnose failed or unreliable agent workflows by classifying bad assumptions, missing observations, tool misuse, wrapper failures, hidden repair loops, incomplete validation, handoff gaps, and repeated failure patterns. Use after a failed harness run, flaky agent output, or confusing validation loop.
Review agent-generated changes against project rules. Use when asked for a review, before opening a PR, after large Codex edits, or when checking diffs for correctness, security, architecture, tests, docs drift, dependencies, migrations, and release risk.
Generate or maintain a minimal high-signal AGENTS.md for coding agents. Use whenever a repo needs agent instructions, an existing AGENTS.md is too long or vague, or project docs/scripts need a concise routing map for Codex.
Define and mechanically enforce architecture boundaries for a repo. Use when a project needs allowed dependency rules, forbidden imports, layer documentation, dependency maps, circular dependency checks, or protection against agent-created architectural drift.
Scaffold a new TypeScript web, mobile, API, or full-stack project with Better-T-Stack, then harden it with the Pax Fullstack Harness. Use whenever the user wants a new TypeScript app scaffold, mentions Better-T-Stack, asks for a modern type-safe stack, or wants Codex to start a repo that is agent-ready from day one.
Use guided Chrome DevTools MCP setup and workflows for browser runtime debugging. Use when a web app needs console, network, DOM, accessibility, Lighthouse, performance, responsive, or live-browser investigation beyond normal tests.
