checkpointing

GraphSmith is a free, open-source tool that generates AI agent workflows that survive crashes, never duplicate work and don't hallucinate code.

Checkpoint sequential JavaScript and agent workflows, reuse completed steps after failure, bound retries and supply stable idempotency keys. No cloud required. 本地长任务分步保存、失败恢复、复用成果、有界重试与幂等键，无需云服务。

Find the checkpoint interval that maximizes training goodput: split wall-clock time into goodput, saving, rework and restart with Daly's exact model. 千卡训练的 checkpoint 间隔计算器

Preserve compiled ARM64 code and initialized objects as portable Node and browser APIs.

Keep long Codex tasks recoverable across context compaction with incremental checkpoints, freshness-gated restore, and no extra model calls by default.

ZCode skill for task-continuation / auto-resume (断点续跑): stage decomposition, checkpoints, reality-checked resume after interruption, anti-duplication, 3-strike error escalation, evidence-gated COMPLETED.
