Limit fallback

When Claude Code stops mid-task, move the harness before Codex edits code.

A limit or outage is not only a model switch. The fragile part is the operating context around the model: instructions, skills, hooks, MCP config, and validation notes.

Bring Your AI does not raise Claude Code limits. It gives you a local fallback path so Codex can start with the portable parts of the Claude Code setup and explicit notes for the parts that do not map cleanly.

The fallback sequence

  1. Freeze task state. Write changed files, failing command, next step, and half-written assumptions into the repo before switching tools.
  2. Run the first-party Codex import path if available. Use it as the initial import and checklist source.
  3. Preview the Bring Your AI move locally. Preview reports support and source safety without exposing file lists or generated content.
  4. Apply with merge policy only after preview. Merge keeps existing Codex setup unless you explicitly choose a different policy.
  5. Run the environment check. Confirm local tool state before asking Codex to continue the task.

What the target agent should check

Task handoffChanged files, failing tests, current goal, and next command.
Instruction scopeActive rules versus old session artifacts that should stay review-only.
Hook equivalenceClaude Code hooks and per-agent restrictions that Codex cannot enforce directly.
MCP secret referencesKeychain, env, and vault references preserved instead of pasted values.

Agent-readable version

The same runbook is available as structured JSON for agents, docs bots, and directory reviewers:

curl -s https://bringyour.ai/claude-code-limit-fallback.json
No-data remote invariant.

The public JSON route and remote MCP are descriptive. They do not accept harness files, generated memories, rules, API keys, GitHub handles, repo paths, or source content. Actual migration runs locally.
