Put a hard stop between your coding agent and a runaway bill.
Budget worksheets, kill-switch prompts, routing decisions, and review gates for Claude Code, GitHub Copilot, OpenAI Codex/API workflows, and Gemini-style coding agents.
Built for source-verified decisions and practical run control. No bill-reduction promise.
Use it before the agent starts
Estimate the run
Classify the task, allowed files, likely expensive steps, retry caps, and human checkpoints.
Set hard stops
Give the agent max turns, max files, max failures, approval gates, and a blocker-note format.
Route by phase
Separate planning, bounded execution, and final review instead of using one open-ended premium run.
Prompt library
Includes prompts for budget estimation, Claude Code guarded execution, Copilot premium-request containment, OpenAI Codex/API workflows, Gemini-style quota checks, multi-vendor routing, runaway-loop prevention, and post-run review.
Templates
Includes an agent-run budget worksheet, circuit-breaker checklist, vendor routing matrix, budget alert setup checklist, and post-run review form. Every template includes a worked sample.
Built for current vendor reality
The kit points users to official OpenAI, Anthropic, GitHub, and Google billing or rate-limit sources before making plan-sensitive decisions. It avoids precise pricing claims that can go stale.
