1. What happened before the handoff
A solo builder planned in Claude, implemented part of the work in Codex, and now wants Claude Code to debug the next issue without a long recap.
2. Local source files
.contextos/
handoffs/
latest.md
tasks/
active/
TASK-004.md
context/
constraints.md
Safe sample data
The sample uses a fake project named Acme Notes and contains no private repo names, customer data, production hostnames, or credential-shaped values.
3. Command
checkpoint continue --from codex --for claude-code
4. Generated continuation pack
# Continuation Pack
Current task: TASK-004 improve empty-project recovery
Previous agent: codex
Next agent: claude-code
## Relevant context
- Acme Notes is a sample CLI docs project.
- Keep project memory readable and local.
- Do not add hidden state.
## Files to inspect
- .contextos/tasks/active/TASK-004.md
- .contextos/handoffs/latest.md
- .contextos/context/constraints.md
## Next action
Reproduce the empty-project path and improve the recovery message.
Illustrative sample based on v0.1.0 behavior; verify exact output
with checkpoint --help.
5. Why this is safe to inspect
The pack is generated from local Markdown project memory. You can open the source files, edit them, diff them, and decide what to share with the next tool.
