Used together 6
- Plan with Claude Code, execute with Codex via MCP
Claude Code plans and reviews, Codex executes through the Codex MCP, and notes and skills live in Obsidian.
- Keep agent state in init.d-style files to survive compaction
Instead of one PROGRESS.md, ordered runlevel-style state files plus fork/wait subagents survived two 230k-token compactions.
- Gate “done” claims behind a real test run
One dev found 69% of “done” claims false, another 35% of “tests pass” claims; both re-run checks before the agent may stop.
- Have a small local model vet agent shell commands
A hook sends every command to a 322M local model that returns allow, review or block; tuned against false blocks and chained commands.
- Extract your memories from thousands of chats
Instead of an agent run, a builder had Opus 5.5 extract memories across Claude, Cursor and Codex chats to stay portable.
- Route by task type and make each agent review the other
