config_overridesparameter for overriding arbitrary config values. - Update Inspect dependency to 0.3.152 (required for bridged tools).
- Codex CLI: Use
RUST_LOG=warning(rather thandebug) to reduce amount of output produced byexec(). - Codex CLI: Enable setting a custom
home_dir(override default of ~). - Handle multiple
run()calls to the same agent (resume session and send only new messages in prompt).
- Copy agent binary executables to /var/tmp/ (more liberal default permissions)
- Agent binary chmod+x using "root" user for scenarios where they agent isn't root.
- Codex CLI: Execute
codexusing theuserpassed tocodex_cli().
- Claude Code: Pass
modelthrough to agent bridge to accomodate scenarios where a non-Inspect model is specified. - Claude Code: Remove
small_modelsetting as it conflicts with aforementioned fix to non-Inspect model.
- Codex: Eliminate use of
--include-plan-tooloption (no longer available as plan mode is now always on).
- Codex CLI now uses the latest version of codex, which includes the
