Context Bridge

Context Bridge (cb) moves the useful, observable part of a coding session between agents without claiming to transfer hidden model state. It keeps a local canonical event log, reconciles the repository before a handoff, and generates a redacted package for the next supported agent.

What it carries

A handoff is working context, not an opaque transcript dump. Context Bridge can retain supported messages, tool activity, commands, tests, decisions, assumptions, errors, file activity, Git state, checkpoints, and the next action. The canonical log stays local; each handoff is derived from it.

The normal workflow

Start or import a session, inspect the derived context, then launch the next agent. The CLI preserves the source session and lets the operator preview a handoff before it reaches another agent.

12345cb doctor --verbose
cb run opencode
cb import opencode --session <opencode-session-id>
cb continue --session <bridge-session-id> --to claude --preview
cb continue --session <bridge-session-id> --to claude

Use getting started for installation and first-run checks, then read session transfer for the supported import and continuation flows.

Compatibility is deliberate

Context Bridge uses versioned, documented adapter profiles instead of reading vendor databases or guessing flags. OpenCode 1.18 supports structured discovery and import. Claude Code 2.1 and Codex CLI 0.145 support documented bootstrap prompts and native resume for sessions Context Bridge already linked.

When a detected version is not verified, cb doctor --verbose reports it and the CLI falls back to a manual handoff rather than treating an undocumented integration as safe. This makes a failed capability check an explicit operator decision, not silent data loss.
