Coding agents

View as Markdown Edit on GitHub Docs at 1675df8

Termbridge can prepare coding agents inside Daytona sandboxes by installing their CLIs and syncing your existing auth. This keeps the sandbox ready to use without re-logging in.

Supported agents

  • Claude Code (claude)
  • Codex (codex)
  • OpenCode (opencode)

Enable automatic setup by selecting agents explicitly:

Shell
export TERMBRIDGE_SANDBOX_AGENTS=claude-code,codex,opencode

Or enable all known agents:

Shell
export TERMBRIDGE_SANDBOX_AGENT_AUTO=true

When automatic setup is enabled, Termbridge will:

  • Install agent CLIs inside the sandbox (via npm install -g).
  • Sync local auth files into the sandbox.
  • Forward supported API keys into the tmux session.

Local auth files are discovered from these defaults:

  • ~/.claude/.credentials.json
  • ~/.codex/auth.json
  • ~/.config/opencode/opencode.json

Manual auth sync

If you prefer manual control, you can specify auth paths directly:

Shell
export TERMBRIDGE_SANDBOX_AGENT_AUTH_PATHS=~/.claude/.credentials.json,~/.codex/auth.json,~/.config/opencode/opencode.json

Need custom destinations inside the sandbox? Use explicit mappings:

Shell
export TERMBRIDGE_SANDBOX_AGENT_AUTH_MAPS=~/.claude/.credentials.json=/home/daytona/.claude/.credentials.json

API keys and extra env vars

Termbridge forwards common agent API keys automatically. Add additional env var names via:

Shell
export TERMBRIDGE_SANDBOX_AGENT_ENV=CUSTOM_TOKEN,ANOTHER_SECRET

Controlling installation

If you want to skip installing CLIs in the sandbox, set:

Shell
export TERMBRIDGE_SANDBOX_AGENT_INSTALL=false

To override the install packages entirely:

Shell
export TERMBRIDGE_SANDBOX_AGENT_PACKAGES=claude-code,codex,opencode

Note Auth sync copies local credentials into the sandbox. Only use this with sandboxes you trust, and prefer ephemeral sandboxes with TERMBRIDGE_SANDBOX_DELETE_ON_EXIT=true.
