Gabriel Peal 6b0c486861 [MCP] Render full MCP errors to the model (#5298 )

Previously, the model couldn't see why MCP tool calls failed, many of
which were the model using the parameters incorrectly. A common failure
is the model stringifying the json for the notion-update-page tool which
it then couldn't correct.

I want to do some system prompt massaging around this as well. However,
it is crucial that the model sees the error so it can fix it.

codex-core

This crate implements the business logic for Codex. It is designed to be used by the various Codex UIs written in Rust.

Dependencies

Note that codex-core makes some assumptions about certain helper utilities being available in the environment. Currently, this

macOS

Expects /usr/bin/sandbox-exec to be present.

Linux

Expects the binary containing codex-core to run the equivalent of codex sandbox linux (legacy alias: codex debug landlock) when arg0 is codex-linux-sandbox. See the codex-arg0 crate for details.

All Platforms

Expects the binary containing codex-core to simulate the virtual apply_patch CLI when arg1 is --codex-run-as-apply-patch. See the codex-arg0 crate for details.
