[Feature]: Support for a global agent prompt (e.g. ~/.claude/CLAUDE.md) #1233

Problem or use case
The ~/.claude/CLAUDE.md file is very useful to prevent Claude from co-authoring itself or telling him how I want him to do things. It works fine when using the Claude CLI directly, but t3code doesn't seems to pick it up. There's no way to have global preferences that apply across all projects without copy-pasting the same file everywhere.
This is based on my experience with Claude specifically, I haven't tested with Codex or other providers, but the concept should be provider-agnostic.
Proposed solution
Import the global prompt file (e.g. ~/.claude/CLAUDE.md or a provider-agnostic ~/.t3code/global-prompt.md) before the project-specific one, so project config can override global defaults. Or have a global prompt option in the user settings that works regardless of the agent provider.
Why this matters
Most of my agent instructions are personal preferences (coding style, interaction patterns, behaviors), not project-specific. Having to duplicate them across every repo is annoying and easy to forget.
Smallest useful scope
Load a single global prompt file and prepend it to the project-level agent prompt before sending to the provider.

Adding the following to your
~/.claude/settings.jsonshould work and absolutely does when using Claude Code directly.CLAUDE.mdis probably valid too.All that being said, you're absolutely right that T3 Code isn't reading the settings.json either. So ultimately the same issue but worth noting that pretty much any environment config isn't working as expected.

Okay, thanks. I didn't know that (honestly, I wasn't really looking into it too deeply).
That's one less thing in my claude.md then
