Streaming Export & Cursor Integrity
Protect paged and streaming exports from cursor leaks, pagination drift, partial reads, lost flushes, unsafe replacement, and inconsistent snapshots. This bundle joins async-generator cleanup with exact byte and record integrity from query through final file publication. Use it when large exports work normally but truncate, duplicate, omit, or retain resources after timeout, cancellation, retry, or concurrent updates.
Works with every agent that reads SKILL.md — Claude Code, Cursor, Codex CLI, Gemini CLI, GitHub Copilot, Windsurf, OpenClaw, and more.
One payment, lifetime access. 8 skills unlock instantly in your library.

Repair Async Generator Cleanup Bugs
Example session with this skill installed
Our TypeScript service wraps a broker subscription in two async-generator adapters. Breaking from for-await closes the outer generator, but the inner subscription keeps receiving messages and its heartbeat timer survives. A pending next() can also resolve after cancellation and publish one more value. Repair locally with a fake subscription and controlled promises. Preserve message order, buffer size, retry behavior, and timeout values; do not connect to the broker.
- Read your context and instructions
- Compiled the repair async generator
Cleanup leak found. The adapter forwards next but not return, so breaking from for-await leaves the source producer and subscription alive. The repair forwards all terminal operations, makes finalization single-owner, cancels the pending read, preserves the original error, and verifies that no value or resource survives termination.
