Eric Traut 9e07892253 [3 of 3] Support images in TUI goals (#27510)
## Stack

1. [1 of 3] Support long raw TUI goal objectives - #27508
2. [2 of 3] Support long pasted text in TUI goals - #27509
3. **[3 of 3] Support images in TUI goals** - this PR

## Why

The first two PRs make goal definitions resilient to long text, but
`/goal` still dropped image inputs from the composer. That meant a user
could attach images while defining a goal and the resulting goal
continuation would not have any useful reference to those images.

Goal state still persists only objective text, so image inputs need to
become paths or URLs that the agent can read later.

## What Changed

- Extends TUI `GoalDraft` with local image attachments and remote image
URLs.
- Copies local goal images through the app-server filesystem layer into
the managed goal attachment directory, then rewrites active image
placeholders to file references.
- Appends unplaced local images and remote image URLs to the objective
as referenced image files or URLs.
- Preserves goal image metadata through live `/goal` submission and
queued `/goal` dispatch.

## Verification

- Added goal materialization coverage for local image files and remote
image URLs.
- Added/updated TUI slash-command coverage showing `/goal` drafts
include attached images instead of dropping them.

## Manual Testing

- Attached an image by bracketed-pasting its local path into a live
`/goal` composer. The `[Image #1]` placeholder became a server-host
`image-1.png` reference, copied bytes matched exactly, and no attachment
was written under the TUI's local home.
- Deleted an image placeholder before submitting a small goal and
verified no image was copied.
- Attached PNG and JPEG files to the same goal. Placeholder order was
preserved as `image-1.png` and `image-2.jpg`, and both remote copies
matched their source bytes.
- Tried extensionless, malformed-extension, and
extension/content-mismatched paths; the composer rejected them as image
attachments before goal dispatch rather than creating misleading managed
image files.
- Combined a local image, a large pasted block, and enough raw text to
exceed 4,000 characters. The remote attachment directory contained the
image, paste sidecar, and `goal-objective.md`; all embedded references
used server-host paths and both payloads matched their sources.
- Submitted an image replacement while a goal was active, verified no
image was copied before confirmation, then canceled and confirmed the
attachment count was unchanged.

Codex CLI is a coding agent from OpenAI that runs locally on your computer.

Codex CLI splash


If you want Codex in your code editor (VS Code, Cursor, Windsurf), install in your IDE.
If you want the desktop app experience, run codex app or visit the Codex App page.
If you are looking for the cloud-based agent from OpenAI, Codex Web, go to chatgpt.com/codex.


Quickstart

Installing and running Codex CLI

Run the following on Mac or Linux to install Codex CLI:

curl -fsSL https://chatgpt.com/codex/install.sh | sh

Run the following on Windows to install Codex CLI:

powershell -ExecutionPolicy ByPass -c "irm https://chatgpt.com/codex/install.ps1 | iex"

Codex CLI can also be installed via the following package managers:

# Install using npm
npm install -g @openai/codex
# Install using Homebrew
brew install --cask codex

Then simply run codex to get started.

You can also go to the latest GitHub Release and download the appropriate binary for your platform.

Each GitHub Release contains many executables, but in practice, you likely want one of these:

  • macOS
    • Apple Silicon/arm64: codex-aarch64-apple-darwin.tar.gz
    • x86_64 (older Mac hardware): codex-x86_64-apple-darwin.tar.gz
  • Linux
    • x86_64: codex-x86_64-unknown-linux-musl.tar.gz
    • arm64: codex-aarch64-unknown-linux-musl.tar.gz

Each archive contains a single entry with the platform baked into the name (e.g., codex-x86_64-unknown-linux-musl), so you likely want to rename it to codex after extracting it.
