Free guides, interactive tools, and deeper resources for Claude Code operators facing Anthropic's Agent SDK monthly credit change.
Before June 15, a Claude Code subscriber running claude -p automation drew from the same usage pool as their interactive session. After June 15, the Agent SDK path draws from a separate monthly dollar credit, sized by plan. Beyond the credit, calls bill at standard API rates (if extra-usage is enabled) or stop (if it is not).

| Plan | New monthly SDK credit |
|---|---|
| Pro / Team Standard | $20/mo |
| Max 5x / Team Premium / Enterprise (usage-based) | $100/mo |
| Max 20x / Enterprise (seat-based Premium) | $200/mo |
| Direct API key only | Unaffected |
Community reaction in the first 24 hours after the May 13 announcement: approximately 4,039 points across r/ClaudeCode, r/ClaudeAI, and Hacker News. Multiple independent operators report 10x effective cost increase for typical heavy-SDK workloads.
5-question interactive aid. Outputs your projected post-cliff monthly bill, credit utilization, and a recommended path in 30 seconds. All browser-side, no signup.
5問の interactive な道具の日本語版。月の請求の予測と推奨の経路を返す。すべて browser 内で完結。
5問の入力 (plan / M の値 / 自動化の頻度 / 予算の余地 / 技術の整備の余地) から、 4経路 (対話への畳み込み / claude -p の最適化 / API への移行 / 混在) のうち1経路を推奨。 上の Path Finder が「いくら超過するか」 を、 本道具が「どの経路を選ぶか」 を articulate する補完の関係。 Token Book と Migration Playbook の段の動線を内包。
The structured response framework. Four paths, the single number that picks between them, the opt-in trap, the 32-day timeline (measure → decide → implement → verify).
5 effective-usage rows × 5 alternative platforms. Shows where Cursor Ultra and Codex Pro 20x absorb workloads that post-cliff Claude Code Max would charge $1,000-1,500/mo overage on.
日本語の整理。単一の指標 M、4つの経路、加入の落とし穴、32日の時系列。Max 5x で `claude -p` の自動化を運用している利用者の判断の整理。
The single piece that walks through what changes, the M number, all four paths (consolidation / claude -p optimization / API migration / mixed routing) with their fit + don't-fit articulation, and the 15-minute pre-flight audit. Embeds the path picker and credit cliff calculator as the operator-side flow.
Stay / Switch / Stack framework. Edition 1 live since 2026-04-25. Edition 2 incorporates the June 15 cliff as Trigger 12 (billing-system change) and expands Path A' (harness reduction), Path B' (switch routes), Path D (hybrid delegation). Free update for all Edition 1 buyers. ~120 pages.
Companion on a separate axis: when Claude Code's response surface claims success while the underlying state diverges. 99 cases (15 in-text + 84 Appendix D), three-stage framework, 14 operator defenses, 5 detection tools (all implemented and tested, 165+ test cases passing).
Zenn paid book (14 chapters, chapter 1 free). Chapter 13 (added 2026-05-28) covers the 9-issue API-error / guardrail-rejection cluster behind Pool 2 overage with three loss modes (Mode A: 5 paths where session ends, Mode B: 2 guardrail false-positive paths, Mode C: 2 paths where operator-side recovery surface is near zero), monthly $20-$140 loss estimate, and a Stop-hook sketch. Direct successor to Path 2 (claude -p optimization) in the Path Picker.
Each month: 4-8 verified incidents, a deep-dive case, copy-paste safety hooks, an updated checklist. June 2026 issue (ships 6/1) centers on the cliff context, with one chapter on the pricing-quality coupling structure.
Three chapter intros: complexity trap, pricing-quality coupling, irreversible operations, trust boundary collapse. Includes the 5/14 update with the 4,039-point community signal integration.
