Use when setting up or reviewing a development environment, especially Varlock env schemas, gitignored env files, macOS Keychain/local secret storage, SOPS/age optional GitOps secrets, CI secret access, dotenv bootstrapping, or secure local dev onboarding.
Use when the repo has .beans or the user mentions beans, beans-prime, flat-file issues, task tracking, or issue status changes.
Opinionated JB GitHub Actions release-attempt workflow. Use only when the repo already has .github/workflows/jb-release-v1.yaml (or equivalent JB release-attempt workflow) or the user explicitly asks to set it up. Do not use for ordinary local releases; use jb-local-release instead.
Use when the user asks to run a local release flow: prepare version/changelog changes, run local checks, commit, tag, and optionally publish only when explicitly requested.
Query MDN Web Docs through the official MDN MCP server using a persistent mcporter config, avoiding a direct MCP connection in the agent harness. Use when checking current web platform docs, CSS/HTML/JavaScript/Web API behavior, MDN browser compatibility data, Baseline support, or when the user asks whether a browser feature is supported.
Use when the user asks for Chrome MCP/DevTools MCP via mcporter, existing Chrome tabs, console/network inspection, screenshots, or performance traces.
Use for JB browser-testing decisions: prefer PinchTab, choose agent-browser only when needed, and avoid playwriter/playwright-mcp.
Use when the user mentions ADR, MADR, decision record, architectural decision, design decision, tech decision, or documenting architecture choices.
