A Subscription-First AI Workspace

An eight-part series moving from US$20 plan comparison through measurement, context, sessions, tool output, model routing, orchestration, and break-even decisions.

Comparing US$20 AI coding subscriptions without API keys1. A Subscription-First AI WorkspaceexperimentalComparing US$20 AI coding subscriptions without API keysCompare the roughly US$20 Gemini CLI, Codex, and Claude Code subscriptions with Z.ai, Kimi Code, and OpenCode Go, then design a no-key workflow that reduces usage per completed task.Measure subscription AI by completed work2. A Subscription-First AI WorkspaceexperimentalMeasure subscription AI by completed workBuild a baseline that compares verified work per consumed allowance and rework time without pretending that provider requests, messages, credits, and tokens are interchangeable.Put a budget on AI coding context3. A Subscription-First AI WorkspaceexperimentalPut a budget on AI coding contextReduce repeated subscription usage by separating durable rules, task contracts, and temporary evidence instead of duplicating long AGENTS.md, CLAUDE.md, and GEMINI.md files.Handoff AI work without carrying the session4. A Subscription-First AI WorkspaceexperimentalHandoff AI work without carrying the sessionStart a fresh session for a new task, compact only a continuing task, and switch providers with evidence-based handoffs instead of copied conversation history.Budget logs, tests, diffs, and MCP output5. A Subscription-First AI WorkspaceexperimentalBudget logs, tests, diffs, and MCP outputConstrain shell logs, test results, diffs, searches, and MCP responses in stages so an agent keeps the evidence needed to solve the problem without carrying unbounded tool output.Route subscription work from light to deep models6. A Subscription-First AI WorkspaceexperimentalRoute subscription work from light to deep modelsClassify work as exploration, everyday implementation, or high-stakes reasoning, then start with the lightest suitable model and escalate only on observable failure signals.Orchestrate AI subscriptions without API keys7. A Subscription-First AI WorkspaceexperimentalOrchestrate AI subscriptions without API keysUse the official signed-in Gemini CLI, Codex, Claude Code, and Kimi Code clients as explorer, implementer, and reviewer roles in one repository without duplicating work.Set break-even and cancellation rules for AI subscriptions8. A Subscription-First AI WorkspaceexperimentalSet break-even and cancellation rules for AI subscriptionsCompare one US$20 subscription, several core subscriptions, and a higher tier by total cost per accepted task, then define explicit rules to keep, add, upgrade, or cancel.
